Bioaccumulation, biotransformation and trophic transfer of arsenic in the aquatic food chain.
The occurrence, distribution, speciation, and biotransformation of arsenic in aquatic environment (marine and freshwater) have been studied extensively by several research groups during last couple of decades. However, most of those studies have been conducted in marine waters, and the results are available in a number of reviews. Speciation, bioaccumulation, and biotransformation of arsenic in...
متن کاملBiological and chemical factors of importance in the bioaccumulation and trophic transfer of persistent organochlorine contaminants in Arctic marine food webs.
Recent studies of arctic marine food webs have provided detailed insights regarding the biological and chemical factors that influence the bioaccumulation and trophic transfer of persistent organochlorine (OC) contaminants in aquatic systems. The present paper summarizes the recent literature with an emphasis on identifying important ecological factors for explaining variability of OC concentra...
متن کاملBiodynamic understanding of mercury accumulation in marine and freshwater fish
Mercury (Hg) is a global environmental pollutant that has been the cause of many public concerns. One particular concern about Hg in aquatic systems is its trophic transfer and biomagnification in food chains. For example, the Hg concentration increases with the increase of food chain level. Fish at the top of food chain can accumulate high concentrations of Hg (especially the toxic form, methy...
متن کاملThe distribution characteristics and bioaccumulation of arsenic in food webs around a realgar mine, China
Arsenic (As) is a ubiquitous but carcinogenic metalloid element. Shimen realgar mine has the largest As mine in Asia with a mining history of 1500 years, therefore it could induce substantial increase of arsenic concentration in the environment and living organisms, and ultimately into human bodies. The total As in surface soil, sediments and water were in the range of 35-5000 mg/kg, 43-4543 mg...
متن کاملMathematical relationships between metrics of chemical bioaccumulation in fish.
Five widely used metrics of bioaccumulation in fish are defined and discussed, namely the octanol-water partition coefficient (KOW ), bioconcentration factor (BCF), bioaccumulation factor (BAF), biomagnification factor (BMF), and trophic magnification factor (TMF). Algebraic relationships between these metrics are developed and discussed using conventional expressions for chemical uptake from w...
