Chronic toxicity of ethyl parathion and isobutoxyethanol ester of 2,4-dichlorophenoxyacetic acid to estuarine juvenile and adult crabs
The chronic toxicity of ethyl parathion and isobutoxyethanol ester of 2,4-dichlorophenoxyacetic acid was determined for the crabs Uca uruguayensis and Chasmagnathus granulata collected in Argentina in 1989. Parathion toxicity was more time-dependent than 2,4-D. Four-week LC50 values for parathion we...
