EXECUTIVE SUMMARY The Alberta Capital Airshed (ACA) is a not-for-profit, multi-stakeholder organization that facilitates the sharing of easily accessible air quality data and the development of comprehensive air quality management plans with all stakeholders in the Alberta Capital Region. For further information on the ACA, please visit www.capitalairshed.ca. The air monitoring network consists of a continuous monitoring network, an intermittent particulate monitoring network, and a passive monitoring network. Figure 2 of the main report present the locations of the continuous air monitoring stations. The stations are owned and operated independently by ACA members including the Strathcona Industrial Association, Alberta Environment and Sustainable Resource Development (ESRD) and Lehigh Cement. The ACA contains nine continuous monitoring stations plus an additional station operated by ESRD at their Edmonton office (McIntyre). The continuous network measures sulphur dioxide (SO2), hydrogen sulphide (H2S), nitrogen oxides (NO, NO2, NOx), carbon monoxide (CO), ozone (O3), total hydrocarbons (THC), methane (CH4), non-methane hydrocarbon (NMHC), particulate matter (PM2.5 and PM10), ambient temperature, relative humidity (RH), wind speed and wind direction. In 2012, the annual instrument uptime for the continuous monitoring parameters exceeded 90%, a requirement of the Alberta Air Monitoring Directives (AMD), with the exception of 71.9% for PM2.5 at the Edmonton South Station. Table ES-1 summarizes the annual average concentrations for the year of 2012. There were eight exceedance events for H2S, as well as twenty-two exceedance events for PM2.5. The Sherwood Park, Gold Bar, Beverly, and Woodcroft stations also measure 24-hour intermittent samples for particulate matter every six days following the sampling schedule of the National Ambient Pollution Surveillance Network (NAPS, Environment Canada). The intermittent monitoring program measures 24-hour average concentrations for PM2.5, PM10, and TSP using dedicated air samplers. Table ES-2 summarizes the monitoring results for 2012. There was one exceedance event for 24-hour average PM2.5 on July 14, 2012 at all four stations. The exceedance was due to wildfire smoke in the capital region. The Woodcroft station recorded five exceedance events for 24-hour average TSP, attributed to construction activities near the station. The ACA passive network includes six monitoring sites as shown in Figure 3 of the main report. Each site monitors 30-day average concentration for SO2, NO2, and O3. Table ES-3 summarizes the annual average concentrations results for 2012. There were no exceedance events in 2012.

ACA Air Monitoring Network

The ACA air monitoring network includes a continuous monitoring network, an intermittent particulate monitoring network and a passive monitoring network. The ACA management zone currently contains ten (10) continuous air monitoring stations. The air monitoring stations are operated by the Strathcona Industrial Association (SIA), Lehigh Cement and Alberta Environment and Sustainable Resource Development (ESRD). Figure 2 illustrates the locations of the continuous monitoring stations. The measured air quality parameters are summarized in Table 1. Among the continuous monitoring stations, the Sherwood Park, Gold Bar, Beverly, and Woodcroft stations also measure 24-hour intermittent samples for particulate matter every six days following the sampling schedule of the National Ambient Pollution Surveillance Network (NAPS, Environment Canada). The intermittent monitoring program measures fine particulate matter (PM2.5) at all four stations. In addition, the Woodcroft station also measures inhalable particulate matter (PM10) and total suspended particulate matter (TSP). The ACA passive monitoring network consists of six sampling sites operated by the SIA. Figure 3 illustrates locations of the passive monitoring sites. Each site measures 30-day average for SO2, NO2, and O3. Passive samples are collected on a monthly basis.

Summary of Air Monitoring Data

2.1

Summary of Exceedances above the AAAQO’s

The ACA air monitoring network measures air pollutant concentrations to indicate the general quality of air in the airshed zone. Ambient air quality data is used to investigate the trends in air quality resulting from emissions of anthropogenic sources (industry, motor vehicles, etc) and natural biological processes (such as forest fires, decomposition of organic matter, etc). Table 2 summarizes the number of exceedances above the Alberta Ambient Air Quality Objectives (AAAQO) for the year of 2012. For the continuous monitoring network, there were seven exceedance events for 1-hour H2S, one exceedance event for 24-hour H2S, and twentytwo exceedance events for 24-hour PM2.5. The H2S exceedance events were recorded at the Beverly and Gold Bar stations. The PM2.5 exceedance events were primarily recorded in the summer, with the exception of four exceedances in February. The summer exceedance events were primarily associated with wildfire smoke in the capital region. The February exceedances could be associated with impaired dispersion conditions when the atmosphere was stable, such as during a temperature inversion. For the intermittent monitoring network, there were four exceedance events for intermittent 24-hour PM2.5 and five exceedance events for 24-hr TSP. The PM2.5 exceedance events were due to wildfire smoke; the TSP exceedances at the Woodcroft station were attributed to construction activities in the nearby gravel parking lot. Table 2.

Wind Data Summary

Wind speed and wind direction are important factors that influence regional air quality. The diffusion and dispersion of air pollutant emissions are greatly impacted by variations in wind speed and corresponding air turbulence. Different degrees of turbulence are created by variable mixing conditions due to the vertical gradient of ambient temperatures and terrain roughness unique to each station. Figure 4 presents the wind roses at the ACA continuous monitoring stations. The prevalent winds in this area were primarily from the directions between southeast and southwest sectors, and less frequently from the directions between the west and northwest sectors. The Elmjay station typically recorded a higher wind speed than the other stations, potentially due to the open, flat terrain near this station. The detailed frequency distribution table and wind roses are presented in Appendix I: AMD Summary Tables.

Continuous Air Quality Data

2.3.1

Sulphur Dioxide (SO2)

Sulphur dioxide is a colourless, non-flammable gas with a pungent odour. Natural sources include volcanoes, biodegradation of organic matter, and solar action on seawater. The primary anthropogenic sources of SO2 include fossil fuel combustion, petroleum refining, and smelting sulphide ores. Exposure to SO2 results in numerous effects to the pulmonary system. Healthy subjects exhibit increased airway resistance and bronchoconstriction, decreased maximum expiratory flow and decreased pulmonary function. Asthmatic subjects exhibit similar symptoms but also report increases in asthma symptoms, wheezing, chest tightness, and difficulty breathing. Sulphur dioxide affects vegetation as a result of acute and chronic exposures. Acute exposure to high concentrations of sulfur dioxide can produce injury in the form of foliar necrosis. Long term exposures to low concentration of SO2 have been shown to affect metabolic activity. The current Alberta Ambient Air Quality Objective (AAAQO) for sulphur dioxide was activated on April 15, 2011: •

1-hour average AAAQO = 172 ppb

24-hour average AAAQO = 48 ppb

annual average AAAQO = 8 ppb

Table 3 presents the summary statistics for 1-hour average concentrations for SO2 for the monitoring stations. The annual average concentrations ranged between 1 to 2 ppb. Table 4 summarizes the number of exceedances to Alberta Ambient Air Quality Objectives. There were no exceedance events for the 1-hour, 24-hour, and annual average concentrations in 2012. Figures 5 to 11 present pollutant roses for 1-hour average SO2 for the ACA monitoring stations. The pollutant roses indicate that SO2 concentration was predominantly less than 5 ppb (as shown in green and blue petals). The detailed pollutant rose data are presented in Appendix I: AMD Summary Tables. The concentration distribution tables indicate that more than 90% of the time the 1-hour average SO2 concentration was less than 5 ppb. Figure 12 compares the annual average SO2 concentrations for forty-nine (49) monitoring stations in Alberta. The annual average concentrations of the ACA monitoring stations were ranked the 4th, 5th, 12th, 13th, 15th, 22nd and 28th places. A higher concentration tends to be recorded in the areas with heavy industry and energy operation facilities.

Hydrogen Sulphide (H2S)

Hydrogen sulphide is a colourless, flammable gas that can be identified by humans at relatively low concentrations. It is characterized by a rotten egg odour. Hydrogen sulphide is extremely hazardous and toxic. The gas occurs naturally in coal pits, sulphur springs, gas wells, and biodegradation of sulphur-containing organic matter. It is commonly existent in places such as sewers, sewage treatment plants, and manure stockpiles. Industrial sources of hydrogen sulphide include petroleum, natural gas extraction, refining, pulp and paper manufacturing, rayon textile production, leather tanning, chemical manufacturing, and waste disposal. Hydrogen sulfide is a highly toxic and flammable gas. It is heavier than air and tends to accumulate at the bottom of poorly ventilated spaces. Although very pungent at first, it quickly deadens the sense of smell. Potential victims may be unaware of its presence until it is too late. The current AAAQO for hydrogen sulphide: •

1-hour average AAAQO = 10 ppb

24-hour average AAAQO = 3 ppb

Table 5 presents summary statistics for 1-hour average concentrations for H2S for 2012. The annual average concentrations for H2S ranged between 0.3 and 0.5 ppb. Table 6 summarizes the number of exceedance events for the year of 2012. There were seven (7) exceedance events for 1-hour AAAQO and one (1) exceedance event for 24-hour AAAQO. The exceedance events were detected at the Beverly station and Gold Bar station: •

The Beverly station detected six (6) exceedance events for 1-hour average H2S. During the exceedance events, wind speed was low (≤5km/hr), generally from southwest and southsouthwest directions.

The Gold Bar station detected one (1) exceedance event for 1-hour average H2S. During the exceedance event, wind speed was low (<5km/hr), generally from the north.

The Gold Bar station detected one (1) exceedance event for 24-hour average H2S. During the exceedance event, prevalent wind speed was about 15 km/hr, from the southeast direction. An increased concentration of SO2 was detected during this event, but the concentration was within the AAAQO.

Figures 13 to 17 present pollutant roses for 1-hour average H2S. The pollutant roses indicate H2S concentration in the ambient air was predominantly less than 1 ppb at all stations (as shown in blue petals). The detailed pollutant rose data are presented in Appendix I: AMD Summary Tables. The concentration distribution tables indicate that greater than 90% of the time the 1hour average H2S concentration was less than 1 ppb, with the exception of 87.9% for the Beverly station. Figure 18 compares the annual average H2S concentrations for seventeen (17) monitoring stations in Alberta. The annual average concentrations of the ACA monitoring stations were ranked the 4th, 5th, 7th, 8th, and 10th places.

Nitrogen Dioxide (NO2)

Nitrogen dioxide is a reddish-orange-brown gas with an irritating, pungent odour. Nitrogen dioxide is corrosive, highly oxidizing and non-combustible. Nitrogen dioxide occurs naturally in the environment as a result of forest fires, atmospheric lightning discharges, and biodegradation of nitrogen containing compounds. Anthropogenic sources of NO2 are mainly from combustion processes, such as vehicles emissions, coal combustion, and industrial processes. Acute exposure to NO2 of 2 ppm or lower can cause airway inflammation and alterations in lymphocytes appearance in healthy individuals; individuals with asthma have a greater sensitivity to acute exposures. Pre-exposure to NO2 can increase the responsiveness of mildly asthmatic individuals to inhaled allergens. The effects on vegetation are dependent on a number of factors, for example sensitivity of the species, duration and concentration of the exposure, and stage of growth when exposed. Some of the effects that have been observed include: increase in shoot to root ratio, which results in drought susceptibility; decreased growth; increased shoot nitrogen, which leads to increased susceptibility to pathogen and insect attack; and advanced bud-break, which could lead to frost damage. The current AAAQO for nitrogen dioxide was activated on June 15, 2011: â&#x20AC;˘

1-hour average AAAQO = 159 ppb

â&#x20AC;˘

annual average AAAQO = 24 ppb

Table 7 presents the summary statistics for 1-hour average concentrations for NO2 for 2012. The annual average concentrations ranged between 9.9 ppb to 16.2. The maximum 1-hour average concentration of 156.0 ppb. Table 8 summarizes number of exceedances for the year of 2012. There were no exceedance events recorded in the ACA monitoring network. Figures 19 to 24 present pollutant roses for 1-hour average NO2. The pollutant roses indicate NO2 concentration was predominantly less than 30 ppb at all stations (as shown in blue, green and light green petals). The detailed pollutant rose data are presented in Appendix I: AMD Summary Tables. The concentration distribution tables indicate that greater than 90% of the time the 1-hour average NO2 concentration was less than 30 ppb. Figure 25 compares the annual average NO2 concentrations for forty-two (42) monitoring stations in Alberta. The concentrations for the ACA air monitoring stations were ranked high among the stations. Five of the ACA monitoring stations were ranking among the top seven stations in the province, with the exception of the Sherwood Park station in 12th place. A higher concentration of NO2 tends to be recorded in large cities due to traffic emissions, as well as industrial areas where more combustion sources are present.

Ozone (O3)

Ozone is a highly reactive, colourless gas that is normally present in the troposphere as a result of naturally occurring photochemical and meteorological processes. It has a sharp odour that can often be detected around running electric motors, after lightning storms, and newly mown hay. The effects of ozone are dependent on where it exists. Stratospheric ozone protects the earth from UV light, but ozone can be toxic in the troposphere. Ground level ozone is formed through complex chemical reactions between precursor pollutants, e.g. volatile organic compounds and nitrogen oxides, in the presence of heat and sunlight. Changing weather patterns also contribute to yearly variations in ozone concentrations. Ozone also can be transported into an area from pollution sources hundreds of miles upwind. Potential short-term effects for ozone exposure include pulmonary function reductions, increased airway sensitivities, and airway inflammation. The primary short-term injury is to the lungs, which is characterized by lung congestion, fluid build-up, and bleeding. Inhalation may initiate, accelerate, or exacerbate respiratory tract disease of bacterial or viral origin. Discomfort to individuals may involve coughing, dryness of throat and mucous membranes and of nose and eyes following exposures of high concentrations for short duration. The current AAAQO for ozone is: â&#x20AC;˘

1-hour average AAAQO = 82 ppb

Table 9 presents the summary statistics for 1-hour average concentrations for O3 for 2012. The annual average concentrations ranged between 19 ppb to 23 ppb. The maximum 1-hour average concentration of 73 ppb. Table 10 summarizes the number of exceedances for the year of 2012. There were no exceedance events recorded in the ACA monitoring network. Figures 26 to 28 present pollutant roses for 1-hour average O3. The pollutant roses indicate O3 concentration in the ambient air was predominantly less than 40 ppb at all stations. The detailed pollutant rose data are presented in Appendix I: AMD Summary Tables. The concentration distribution tables indicate that greater than 85% of the time the 1-hour average O3 concentration was less than 40 ppb. Figure 29 compares the annual average O3 concentrations for twenty-two (22) monitoring stations in Alberta. The concentrations for the ACA air monitoring stations were low in the province. The annual average concentrations of the ACA monitoring stations were ranked the 15th, 16th, and 19th places. A lower concentration of O3 tends to be recorded in the areas that have more anthropogenic emission sources, indicating the effects of ozone titration.

Carbon Monoxide (CO)

Carbon monoxide is a colorless, odourless, and tasteless gas that is slightly lighter than air. In the presence of oxygen, carbon monoxide burns with a blue flame, producing carbon dioxide. Carbon monoxide is produced from the partial oxidation of carbon-containing compounds. It forms when there is not enough oxygen to produce carbon dioxide, such as when operating a stove or an internal combustion engine in an enclosed space. Carbon monoxide is toxic to humans and animals when exposed at higher concentrations. Carbon monoxide mainly causes adverse effects in humans by combining with hemoglobin to form carboxyhemoglobin in the blood. This prevents hemoglobin from releasing oxygen leading to hypoxia. Exposures to a high concentration can lead to significant toxicity of the central nervous system and even death. Symptoms of mild acute poisoning include light headedness, confusion, headaches, vertigo, and flu-like effects. Chronic exposure to low levels of carbon monoxide can lead to depression, confusion, and memory loss. The current AAAQO for Carbon monoxide are: â&#x20AC;˘

1-hour average AAAQO = 13 ppm

â&#x20AC;˘

8-hour average AAAQO = 5 ppm

Table 11 presents the summary statistics for 1-hour average concentrations for CO. The annual average concentrations ranged between 0.2 ppm to 0.3 ppm. The maximum 1-hour average concentration of 1.7 ppm and the maximum 8-hour average concentration of 1.1 ppm were both detected at the Edmonton Central station. Table 12 summarizes the number of exceedances for the year of 2012. There were no exceedance events recorded in the ACA monitoring network. Figures 30 to 32 present pollutant roses for 1-hour average CO. The pollutant roses indicate O3 concentration in the ambient air never was predominantly less than 1 ppm. The detailed pollutant rose data are presented in Appendix I: AMD Summary Tables. The concentration distribution tables indicate that greater than 99% of the time the 1-hour average CO concentration was less than 1 ppm. Figure 33 compares the annual average O3 concentrations for eleven (11) monitoring stations in Alberta. The concentrations for the ACA air monitoring stations were low in the province. The annual average concentrations of the ACA monitoring stations were ranked the 1st, 4th, and 5th places. A higher concentration of CO tends to be recorded in large cities, indicating a potential link with traffic emission sources.

Hydrocarbons (THC, CH4, and NMHC)

Hydrocarbons refer to a broad family of chemicals that contain carbon and hydrogen atoms. This includes a number of organic compounds. Sources of hydrocarbons include vegetation, natural biological processes, industrial emissions, transportation, and leisure activities. The total hydrocarbon analyzers employed in the ACA network are unable to differentiate individual hydrocarbon compounds and are limited to the total hydrocarbons (THC), methane (CH4) and non-methane hydrocarbons (NMHC). Currently, there is no ambient air quality objective in Alberta for these hydrocarbons. The typical background THC concentration in Alberta has been reported between 1.9 to 2.4 ppm. Table 13 presents the summary statistics for 1-hour average concentrations for hydrocarbons. The annual average THC concentrations ranged between 1.9 ppm and 2.4 ppm. The maximum 1hour average concentration of 9.7 ppm and the maximum 24-hour average concentration of 4.7 ppm were both detected at the Edmonton East station. Methane was the major component of THC for the ACA stations; non-methane hydrocarbons (â&#x2030;¤ 0.2 ppm annual average) only accounted for less than 10% of THC. Figures 34 to 38 present pollutant roses for 1-hour average THC. The pollutant roses indicate THC concentration in the ambient air predominantly ranged between 1 ppm to 3 ppm. The detailed pollutant rose data are presented in Appendix I: AMD Summary Tables. The concentration distribution tables indicate that greater than 99% of the time the 1-hour average THC concentration was less than 3 ppm, with the exception of the Beverly station (87.5%) and Edmonton East station (94.9%). Figures 39 and 40 present the pollutant roses for 1-hour average CH4. Because CH4 is the major component of THC, the pollutant roses are similar to THC roses. CH4 concentrations primarily ranged between 1 ppm to 3 ppm. The concentration distribution tables (Appendix I: AMD Summary Tables) indicate that greater than 99% of the time the 1-hour average CH4 concentration was less than 3 ppm. Figures 41 and 42 present the pollutant roses for 1-hour average NMHC. The pollutant roses indicate that NHMC concentration in the ambient air was predominantly less than 1 ppm. The concentration distribution tables (Appendix I: AMD Summary Tables) indicate greater than 95% of the time the 1-hour average THC concentration was less than 1 ppm. Figure 43 compares the annual average THC concentrations for thirty-two (32) monitoring stations in Alberta. The annual average concentrations of the ACA monitoring stations were ranked the 11th, 17th, 20th, 30th and 32nd places. The WBEA area detected the highest THC concentrations in the province.

Particulate Matter (PM2.5 and PM10)

Airborne particulates are tiny pieces of solid or liquid matter suspended in the atmosphere. Respirable particulates are fine particles that have the potential to affect human health. Particles with aerodynamic diameters between 2.5 and 10 micrometers are generally removed from inspired air in the nose and throat. Particles that are smaller than 2.5 micrometers (PM2.5) can penetrate into the lungs and are generally referred to as respirable or fine particulate matter. Particles that are between 2.5 microns and 10 microns are generally referred to as inhalable or coarse particulate matters. The total mass concentration of the fine and coarse portions is referred to PM10, or particulate matter smaller than 10 microns aerodynamic diameter. These particles may originate from soil, road dust, agricultural dust, smoke, forest fires, traffic emissions, and industrial sources. Alberta does not have an ambient air quality objective for PM10. The current AAAQO for PM2.5: •

24-hr average AAAQO = 30 µg/m3

Table 14 presents the summary statistics for 1-hour average concentrations for particulate matter. The annual average PM2.5 concentrations ranged between 5 µg/m3 and 9 µg/m3. The maximum 1-hour average concentration of 156 µg/m3 was recorded at the Edmonton East station. The maximum 24-hour average PM2.5 concentration of 75 µg/m3 was detected at the Edmonton McIntyre station. The maximum concentrations were detected in July at all stations, with the exception of the Edmonton South station, as its PM2.5 analyzer was not in operation between June and August. These maximum concentrations are attributed to wildfire smoke in the capital region. The ACA network monitors PM10 at the Edmonton South station. The annual average PM10 concentration was 13 µg/m3. Both the maximum 1-hour average (148 µg/m3) and the maximum 24-hour average (75 µg/m3) were detected on the same day as the maximum PM2.5 concentrations, due to wildfire smoke in the capital region. Table 15 summarizes the number of exceedances for the year of 2012. There were twenty-two (22) exceedance events for 24-hour PM2.5 for the ACA monitoring program. The PM2.5 exceedance events were primarily recorded in the summer, with the exception of four (4) exceedances in February. The summer exceedance events were recorded in July, and are attributed to wildfire smoke in the capital region. The February exceedances could be associated with impaired dispersion conditions when the atmosphere was stable, such as during a temperature inversion. Figures 44 to 51 present pollutant roses for 1-hour average PM2.5. The pollutant roses indicate THC concentration in the ambient air was predominantly less than 20 µg/m3 at all stations. The detailed pollutant rose data are presented in Appendix I: AMD Summary Tables. The concentration distribution tables indicate that greater than 90% of the time PM2.5 concentration was less than 20 µg/m3. Figure 52 presents a pollutant rose for 1-hour average PM10. The pollutant roses indicate PM10 concentration in the ambient air was predominantly less than 30 µg/m3. The concentration distribution table for PM10 indicates that 92.3% of the time, the 1-hour average PM10 concentration was less than 30 µg/m3.

Page 48


Figure 53 compares the annual average PM2.5 concentrations for twenty-six (26) monitoring stations in Alberta. The annual average concentrations of the ACA monitoring stations were ranked the 4th, 9th, 10th, 14th and 21st places. Air quality data from larger than normal wintertime smog events between January and March 2010, as picked up by monitors at Edmonton Centre and Edmonton East as well as a station in Lamont have triggered a mandatory regional response plan that must be completed by Autumn, 2014. The ACA is working with Alberta Environment and Sustainable Resource Development and other stakeholders to develop the plan. Table 14.

Air Quality Health Index

Air Quality Health Index (AQHI) is a health protection tool that is designed to help the public make decisions to protect their health by limiting short-term exposure to air pollution and adjusting their activity levels during increased levels of air pollution. The AQHI uses readings from three air pollutants to calculate a single numerical value to evaluate the health risk associated with air pollution. The three pollutants are fine particulate matter (PM2.5), nitrogen dioxide (NO2), and ground-level ozone (O3). All three pollutants are required to calculate AQHI. Figure 54 illustrates the risk categories and the health messages for the AQHI system. The health risk is classified in four categories: Low (1 to 3), Moderate (4 to 6), High (7 to 10), and Very High (higher than 10).

Figure 54.

Risk classification and health messages for Air Quality Health Index (Environment Canada)

Page 56


Figure 55 compares the AQHI rating among the communities in Alberta. For the City of Edmonton, the ambient air quality was rated Low Risk for 87% of the time; 13% was rated Moderate Risk and 0.2% was rated High Risk. The High Risk rating occurred on January 30, February 29, June 2, June 5, and July 12. The summer High Risk events were characterized by a high concentration of fine particulate matter due to wildfire smoke. The winter High Risk events could be associated with impaired dispersion conditions due to a stable atmosphere. Edmonton recorded the highest percentage of time in the Moderate Risk category. The Moderate Risk events were spread throughout the year and could be attributed to a number of factors, such as weather, wildfire smoke, traffic, etc. In Alberta, the High Risk and Very High Risk ratings were primarily recorded in the Wood Buffalo and Cold Lake areas. During these events, ambient air was characterized by a high concentration of fine particulate matter. Wildfire smoke was the potential cause. For the Moderate Risk events, the occurrence frequency seems to have a general trend with population; i.e. the percentage of Moderate Risk events tends to be higher for a large city, but with some exceptions.

Air Quality for Canadian Cities

The air quality for the twenty most populated metropolitans in Canada are compared for SO2, NO2, CO, O3, PM2.5 and PM10 using the NAPS database (NAPS, 2011). It should be noted that the land use types and the number of the stations in the database vary among the cities. The comparison is based on the available data, and is not intended to justify the quality of air among the cities. Figures 56 to 61 compare the annual average concentration for the cities. The bar charts are arranged in a descending order by city population from left to right. An empty bar indicates the city does not have data in the NAPS database. Figure 56 compares the annual average concentration for SO2. The annual averages ranged from 0.3 to 4.7 ppb. The annual average SO2 concentration in Edmonton (1.1 ppb) was ranked the 9th. The three highest concentrations were recorded at Hamilton (4.7 ppb), Windsor (3.5 ppb) and Halifax (2.8 ppb). Figure 57 compares the annual average concentration for NO2. The annual averages ranged from 6.2 to 17.3 ppb. The annual average NO2 concentration in Edmonton (14.1 ppb) was ranked the 4th. The three highest concentrations were recorded at Calgary (17.3 ppb), Toronto (16.6 ppb) and Vancouver (14.9 ppb). Figure 58 compares the annual average concentration for O3. The annual averages ranged from 14.3 to 28.0 ppb. The annual average O3 concentration in Edmonton (23.7 ppb) was ranked the 13th. The highest concentrations were recorded at St. Catherines (28.3 ppb), Kitchener (27.6 ppb) and Hamilton (27.1 ppb). Figure 59 compares the annual average concentration for CO. The annual averages ranged from 0.17 to 0.45 ppm. The annual average CO concentration in Edmonton (0.24 ppm) was ranked the 9th. The three highest concentrations were recorded at St. Johns (0.45 ppm), Ottawa (0.29 ppm) and Windsor (0.26 ppm). Figure 60 compares the annual average concentration for PM2.5. Only nine cities reported PM2.5 data to NAPS. The annual averages ranged from 5.4 to 10.5 µg/m3. The annual average PM2.5 concentration in Edmonton (8.9 µg/m3) was ranked the 4th. The three highest concentrations were recorded at Calgary (10.5 µg/m3), Montreal (9.9 µg/m3) and Quebec City (9.2 µg/m3). Figure 61 compares the annual average concentration for PM10. Only six cities reported PM10 data to NAPS. The annual averages ranged from 6.6 to 21.2 µg/m3. The annual average PM10 concentration in Edmonton (14.0 µg/m3) was ranked the 3rd. The two highest concentrations were recorded at Regina (21.2 µg/m3) and Calgary (18.6 µg/m3).

Passive Sample Summary

Passives samples are a measure of loadings accumulated over a pre-determined exposure period. The adsorbed analytes are extracted and analyzed in a laboratory, and calculated to the concentrations in the air. For passive samples, Alberta regulates SO2 only. The current AAAQO for passive SO2 was activated on June 15, 2011: â&#x20AC;˘

30-day average AAAQO = 11 ppb

The ACA Passive Network consists of six stations monitoring 30-day averages for SO2, NO2, and O3. In 2012, a total of seventy two (72) samples were collected for SO2, NO2, and O3, respectively. There were no sample failures. Table 16 summarizes the annual average and maximum 30-day concentrations for 2012. Figure 62 presents a time-course chart for 30-day average concentration for passive SO2 samples. The 30-day average concentrations ranged between 1 and 3 ppb. There was no exceedance of the 30-day average AAAQO in 2012. There was no clear temporal trend or spatial trend detected in the passive monitoring network. Figure 63 presents a time-course chart for 30-day average concentration for passive NO2 samples. The measured concentrations ranged between 1.4 and 21.3 ppb. A seasonal trend for NO2 seems to be existent. A higher concentration tended to occur in the winter months. The trend could be associated with the atmospheric conditions. In winter when the air temperature is colder, air pollutants tend to stay longer and accumulate to a higher concentration. In addition, there is a higher chance of forming a thermal inversion layer on cold winter days. Thermal inversion limits atmospheric mixing and caps air pollutants near the ground, forming a higher concentration at the ground level. Figure 64 presents a time-course chart for 30-day average concentration for passive O3 samples. The measurements ranged between 13 to 39 ppb. The chart indicates O3 concentration tended to be higher during the spring months. The concentration of ground-level ozone is the net result of atmospheric formation, transport, and destruction processes. Some research for the Edmonton Capital Region suggests intrusion of ozone from the stratosphere could be an important source of ground-level ozone. During spring and summer, vertical mixing is stronger and may promote downward propagation of upper air ozone to the ground. However, the Ground-Level Ozone in Alberta (AESRD, 1999) report suggests that there were split opinions for relative importance of contributions from upper air intrusion, local photochemistry, and the medium and long-range transport. Further investigation is required.

Intermittent Particulate Sample Summary

The ACA air monitoring network measures intermittent PM2.5 samples at four stations: Sherwood Park, Gold Bar, Beverly, and Woodcroft. In addition, the Woodcroft station also measures PM10 and total suspended particulate (TSP). The sampling program follows the NAPS sampling schedule. A 24-hour intermittent sample was collected every six days throughout the year. In 2012, there were sixty one (61) sampling days, resulting in a total of one hundred eighty three (183) samples. There were two failure samples at the Gold Bar station. A total of one hundred eighty one (181) valid samples were collected. Table 17 presents summary statistics for 24-hour average concentrations for the ACA intermittent particulate monitoring program. There was no significant difference for the annual average PM2.5 concentrations among the four stations. The maximum 24-hour average concentration was detected on July 14, 2012 at all stations due to wildfire smoke in the capital region. Figures 65 and 66 present the time-course chart for 24-hour average concentrations for 2012. Table 18 summarizes the number of exceedances for the year of 2012. There was one PM2.5 exceedance event at each station on July 14, 2012 due to wildfire smoke. There were five exceedance events for 24-hr average TSP at the Woodcroft station. These exceedances were primarily due to construction activities in the nearby gravel parking lot, while some events could be attributed to combined impacts from construction activities and wildfire smoke.
