Biofilm mediated uptake of selenium in streams with mountaintop coal mine drainage


Journal Article

© 2017 Elsevier GmbH Selenium (Se) may cause reproductive toxicity, yet the characteristics of Se bioaccumulation in aquatic food webs are understudied. Stream biofilms were grown in two reaches of Mud River, West Virginia (WV), including one downstream of a coal mine complex and an adjacent, unmined watershed. Mined stream biofilms contained significantly higher Se concentrations compared to unmined biofilms. An inverse relationship between water Se concentrations and biofilm accumulation factors was observed; mined-stream biofilms had an average bioconcentration factor (BCF) of 688 ± 350 fold while unmined-stream biofilms had an average BCF of 14505 ± 2700 fold.
