Sincechromiumcompoundscannotvolatilizefromwater,transportofchromiumfromwatertotheatmosphereisnotlikely,exceptbytransportinwindblownsea sprays.Mostofthechromiumreleasedintowaterwillultimatelybedepositedinthesediment.Averysmallpercentageofchromiumcanbepresentinwaterin bothsolubleandinsolubleforms.Solublechromiumgenerallyaccountsforaverysmallpercentageofthetotalchromium.Mostofthesolublechromiumispresent aschromium(VI)andsolublechromium(III)complexes.Intheaquaticphase,chromium(III)occursmostlyassuspendedsolidsadsorbedontoclayishmaterials, organics,orironoxide(Fe2O3)presentinwater.Solubleformsandsuspendedchromiumcanundergointramediatransport.Chromium(VI)inwaterwilleventually bereducedtochromium(III)byorganicmatterinthewater
Thereductionofchromium(VI)andtheoxidationofchromium(III)inwaterhasbeeninvestigated.Thereductionofchromium(VI)byS-2orFe+2ionsunder anaerobicconditionswasfast,andthereductionhalf-liferangedfrominstantaneoustoafewdays.However,thereductionofchromium(VI)byorganicsediments andsoilswasmuchsloweranddependedonthetypeandamountoforganicmaterialandontheredoxconditionofthewater Thereactionwasgenerallyfaster underanaerobicthanaerobicconditions.Thereductionhalf-lifeofchromium(VI)inwaterwithsoilandsedimentrangedfrom4to140day.Dissolvedoxygenby itselfinnaturalwatersdidnotcauseanymeasurableoxidationofchromium(III)tochromium(VI)in128days.Whenchromium(III)wasaddedtolakewater,aslow oxidationofchromium(III)tochromium(VI)occurred,correspondingtoanoxidationhalf-lifeofnineyears.Theoxidationofchromium(III)tochromium(VI)during chlorinationofwaterwashighestinthepHrangeof5.5?6.0.However,theprocesswouldrarelyoccurduringchlorinationofdrinkingwaterbecauseofthelow concentrationsofchromium(III)inthesewaters,andthepresenceofnaturallyoccurringorganicsthatmayprotectchromium(III)fromoxidation,eitherbyforming strongcomplexeswithchromium(III)orbyactingasareducingagenttofreeavailablechlorine.
Thebioconcentrationfactor(BCF)forchromium(VI)inrainbowtrout(Salmogairdneri)is1.Inbottomfeederbivalves,suchastheoyster(Crassostreavirginica), bluemussel(Mytilusedulis),andsoftshellclam(Myaarenaria),theBCFvaluesforchromium(III)andchromium(VI)mayrangefrom86to192.
Thebioavailabilityofchromium(III)tofreshwaterinvertebrates(Daphniapulex)decreasedwiththeadditionofhumicacid.Thisdecreaseinbioavailabilitywas attributedtoloweravailabilityofthefreeformofthemetalduetoitscomplexationwithhumicacid.Basedonthisinformation,chromiumisnotexpectedto biomagnifyintheaquaticfoodchain.Althoughhigherconcentrationsofchromiumhavebeenreportedinplantsgrowinginhighchromium-containingsoils(e.g., soilnearoredepositsorchromium-emittingindustriesandsoilfertilizedbysewagesludge)comparedwithplantsgrowinginnormalsoils,mostoftheincreased uptakeinplantsisretainedinroots,andonlyasmallfractionistranslocatedintheabovegroundpartofedibleplants.Therefore,bioaccumulationofchromium fromsoil toabove-groundpartsofplantsisunlikely Thereisnoindicationofbiomagnificationofchromiumalongtheterrestrialfoodchain(soil-plant-animal). Thefateofchromiuminsoilisgreatlydependentuponthespeciationofchromium,whichisafunctionofredoxpotentialandthepHofthesoil.Inmostsoils, chromiumwillbepresentpredominantlyinthechromium(III)state.Thisformhasverylowsolubilityandlowreactivityresultinginlowmobilityintheenvironment andlowtoxicityinlivingorganisms.Underoxidizingconditionschromium(VI)maybepresentinsoilasCrO4?2andHCrO4-.Inthisform,chromiumisrelatively soluble,mobile,andtoxictolivingorganisms.Indeepersoilwhereanaerobicconditionsexist,chromium(VI)willbereducedtochromium(III)byS-2andFe+2 presentinsoil.Thereductionofchromium(VI)tochromium(III)ispossibleinaerobicsoilsthatcontainappropriateorganicenergysourcestocarryouttheredox reaction.Thereductionofchromium(VI)tochromium(III)isfacilitatedbylowpH.Fromthermodynamicconsiderations,chromium(VI)mayexistintheaerobiczone

ofsomenaturalsoil.Theoxidationofchromium(III)tochromium(VI)insoilisfacilitatedbythepresenceoflowoxidisableorganicsubstances,oxygen,manganese dioxide,andmoisture.Organicformsofchromium(III)(e.g.,humicacidcomplexes)aremoreeasilyoxidisedthaninsolubleoxides.Becausemostchromium(III)in soilisimmobilizedduetoadsorptionandcomplexationwithsoilmaterials,thebarriertothisoxidationprocessisthelackofavailabilityofmobilechromium(III)to immobilemanganesedioxideinsoilsurfaces.Duetothislackofavailabilityofmobilechromium(III)tomanganesedioxidesurfaces,alargeportionofchromiumin soilwillnotbeoxidizedtochromium(VI),eveninthepresenceofmanganesedioxideandfavorablepHconditions.
Themicrobialreductionofchromium(VI)tochromium(III)hasbeendiscussedasapossibleremediationtechniqueinheavilycontaminatedenvironmentalmedia orwastes.Factorsaffectingthemicrobialreductionofchromium(VI)tochromium(III)includebiomassconcentration,initialchromium(VI)concentration, temperature,pH,carbonsource,oxidation-reductionpotentialandthepresenceofbothoxyanionsandmetalcations.Althoughhighlevelsofchromium(VI)are toxictomostmicrobes,severalresistantbacterialspecieshavebeenidentifiedwhichcouldultimatelybeemployedinremediationstrategies
