TitleToxicity of some aquatic pollutants to fish
Untitled
Abstract

Pesticide residues threaten fish that live in rivers. This study investigated the effects of Nemacur, malathion, and diuron on freshwater fish behavior, mortality, acetylcholinesterase (ACHE) activity, liver biomarkers, and residue accumulation. Fish were exposed to individual concentration of Nemacur, malathion, and diuron at 1 mg/L and to binary mixtures in glass aquarium 16 L capacity. Mortality of fish was also investigated at a range of 0.0–1 mg/L of Nemacur and malathion. The biochemical effects of the tested compounds were recorded. The results showed abnormal fish behavior at low concentration (0.1 mg/L) of malathion, high fish mortality at 0.1 mg/L of Nemacur and mixtures with Nemacur, and no mortality with diuron. Mortality increased and became more intense after 48 h rather than after 24 h. Diuron increased the effect of Nemacur and malathion at low concentration. ACHE was inhibited at …
