Multiple toxicity of two pesticides and two metals to Mysidopsis bahia.

摘要

The toxicity of chemical mixtures has been studied in aquatic systems, however few if any studies have examined the combined effects of metals and organic contaminants. Therefore, the main objective of this study was to determine the acute toxicity (96h) of pesticides and heavy metals, both individually and in combination to the marine opossum shrimp (Mysidopsis bahia). The pesticides chosen for use in this study included chlorpyrifos, an organophosphate insecticide, and chlordane, an organochlorine insecticide. Heavy metals chosen for this study were copper (Cu), in the form of cupric sulfate (CuSO
