| contents | Development of a bioaccumulation model for selenium oxyanions and organoselenium in stream biota. de Bruyn, Adrian M H Heddle, Cybele B Ings, Jennifer Gürleyük, Hakan Brix, Kevin V Luoma, Samuel N Arnold, Mariah C Water Pollutants, Chemical Organoselenium Compounds Selenium Rivers Bioaccumulation Environmental Monitoring Biota Animals British Columbia Selenium (Se) occurs in natural surface waters as a variety of inorganic and organic chemical species, typically dominated by the oxyanions selenate and selenite. Organoselenium species, although hypothesized to be more bioavailable than oxyanions, have rarely been identified or quantified in natural waters and little is known about their fate or bioaccumulative potential. We studied spatial patterns of bioaccumulation in relation to aqueous Se speciation over 5 years at more than 100 locations near coal mine operations in southeast British Columbia, Canada. We used a sequential approach to fitting bioaccumulation model coefficients, first using sites with no detectable organic Se species ( |
