文摘
- •
Accumulation of CPF was not detected in shrimp probably due to biotransformation.
- •
CPF exposure inhibits acetylcholinesterase activity in P. argentinus from 3.5 ng L−1 CPF.
- •
CPF caused oxidative stress, as indicated by increased H2O2, TBARs and CP content.
- •
Mobilization of α-tocopherol from abdomen to cephalothorax was observed.
- •
A strong decrease of MT level occurred as an oxidative stress response.
