ES&E NEWS concentrations of the element normally found in drinking water However, the researchers note that manganese has been reported in greater concentrations in over 50 countries. Chronic manganese exposure has been linked to various neurological effects such as learning disabilities in children, Parkinson’s disease and cognitive decline in adults. Although WHO guidelines are not regulations, they are often used by governments when setting local standards. “These are the de facto standards ... especially for developing countries that don’t have their own regulations or regulatory agencies,” Sarkar tells Chemistry World. “On the basis of these facts, the WHO should really take this matter very

seriously and re-evaluate the guidelines as soon as possible,” he adds. www.rsc.org/chemistryworld

World Toilet Day raises awareness about access to sanitation Of the world’s seven billion people, 2.4 billion people do not have improved sanitation. One billion people still defecate in the open. Poor sanitation increases the risk of disease and malnutrition, especially for women and children. According to the World Health Organization, roughly 50% of all malnutrition cases are associated with repeated diarrhea or intestinal worm infections as a direct result of inadequate water, sanitation and hygiene. A vicious cycle exists between diarrhea and under nutrition, especially for children. Stark inequalities in access to toilets threaten the survival, health, dignity and safety of vulnerable populations, despite their human right to water and sanitation. This is why in 2013 the United Nations General Assembly officially designated November 19 as World Toilet Day. This year, World Toilet Day focuses on the link between sanitation and nutrition, drawing the world’s attention to the importance of toilets in supporting better nutrition and improved health. www.worldtoiletday.info

2015 Lake Erie algal bloom most severe this century Initial analysis by the National Oceanic and Atmospheric Association (NOAA) indicates that the algae bloom, which occurred this year in western Lake Erie, was more severe than the record setting one in 2011. The NOAA ranks the severity of these blooms using an index that measures the amount of biomass over the peak 30days. The 2015 bloom ranked 10.5 on the scale, compared to 10 for 2011. Up to 300 square miles of Lake Erie’s western basin was covered by dense scum in early to mid-August, before cold fronts and high winds broke it up in September. Although the NOAA had forecasted large blooms for 2015 (estimating
