Abstract
Acute toxicity of organophosphate MEP O. O-dimethyl O-3-methyl-4-nitrophenyl phosphorothioate and carbamate NAC 1-naphty-N-methylcarbamate to 11 species of aquatic organisms was determined by the flow-through method of bioassay. Acute toxicity of MEP to kuruma prawn Penaeus japonicus was extremely high followed by red sea bream Pagrus major yellowtail Seriola quinqueradiata and mullet Mugil cephalus with comparative high sensitivity. Common goby Acanthogobius flavimanus and ayu Plecoglossus altivelis showed moderate sensitivity. On the other hand eel Anguilla japonica showed low sensitivity. Acute toxicity of NAC to kuruma prawn was very high followed by yellowtail and common goby with comparatively high sensitivity. Red sea bream Japanese flounder Paralichtys olivaceus black sea bream Acanthopagrus schlegeli mullet and ayu showed moderate sensitivity. Eel showed low sensitivity similar to its susceptibility to MEP. Shortnecked clam Tapes philippinarum and pearl oyster Pinctada fucata both shellfish showed low sensitivity to both of the two pesticides. Apparent intoxication symptoms were observed in aquatic organisms exposed to MEP and NAC. These intoxication symptoms were induced by the neurotoxicity of pesticides. Acute toxicity of MEP and NAC to seawater organisms was comparatively high compared with freshwater organisms.
