Acute toxicity of parathion and 2,4 D to estuarine adult crabs
- Univ. of Buenos Aires (Argentina)
Ethyl-parathion and iso-butoxyethanol ester of 2,4-dichlorophenoxyacetic acid (2,4 D) are among the most extensively used pesticides in Argentina. Their discharge to the Rio de la Plata estuary has been documented. Chasmagnatus granulata (Grapsidae) is a species continuously distributed through the littoral zone of Samborombon Bay. Uca uruguayensis (Ocypodidae) was observed only on the southern edge of the Bay. All stages of the life cycle of these species are included in the aquatic trophic web, which also includes many fish species with great commercial and sport fishing value. The aims of this study were: to evaluate differences in resistance, in terms of acute lethal toxicity, to ethyl-parathion and 2,4 D between adults of C granulata of two localities of the coast, and also between males and females of U. uruguayensis, a species with marked sexual dimorphism.
