| Abstract: | As an important global pollutant,mercury presents in various environmental media in different species,mainly as Hg2+,Hg0,and monomethylmercury.Speciation of mercury plays an important role in not only exposure,toxicity and accumulation of mercury to organisms,but also the fate,transport,and cycling of mercury in the environment.The transformation of mercury is greatly determined by biotic and abiotic environmental factors.Photo-induced transformations were recently recognized as important processes in envir... |
