Additional information

The bioaccumulation and elimination of 14C-EPTC by bluegill sunfish were investigated in a dynamic flow-through system, where the fish were exposed for 28 days at 22°C, followed by depuration in EPTC free water for 14 days. Estimated bioconcentration factors for EPTC were 37, 60, and 110, respectively, in the edible, whole fish, and non-edible fish tissues. According to a classification scheme, the whole-fish bioaccumulation factor (BCF) value suggests the potential for bioconcentration in aquatic organisms is moderate (U.S. EPA, 1999)
