Cyprinus carpio were exposed to penoxsulam in field conditions during 7, 21 and 72 days. The acetylcholinesterase activity in the brain was increased after 7 days and reduced after 21 and 72 days. Muscle AChE was reduced after 72 days. TBARS and GST showed variations during experimental periods. Liver Catalase was reduced at 21 days. Liver protein carbonyl showed reduction and increasing during exposure. This study shows long-term effects of penoxsulam at environmentally relevant concentrations on toxicological parameters of fish.
