摘要：

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 bio-concentration factor (BCF) of 688 +/- 350 fold while unmined-stream biofilms had an average BCF of 14505 +/- 2700 fold.
