Additional information

The effects of diethyl phthalate have been studied in adult male carp (Cyprinus carpio) by exposing them for 28 days. Metabolic enzymes and bioaccumulation were studied at weekly intervals. Behavioural changes were noted at the highest concentration examined. Acid phosphatase, aspartate aminotransferase and alanine aminotransferase activity was reduced and alkaline phosphatase activity was increased.
