Additional information

The bioaccumulation potential of ptBP was studied in the aquatic organism Cyprinus carpio, and a BCF value of 20-43 and 48-88 was achieved following exposure to 40 µg/L and 4 µg/L of ptBP, respectively. Based on the available data on the biotransformation of ptBP and considering the rapid elimination of phenolic compounds from mammalian or aquatic organisms, ptBP is unlikely to bioaccumulate in the food chain.
