Acute toxicity of cypermethrin to the non target organism Hyalella curvispina.


PMID 23270860

Abstract

The acute toxicity of cypermethrin to the amphipod Hyalella curvispina was evaluated by means of a toxicity test under laboratory conditions. Cypermethrin is one of the most widely used insecticides in Argentina. H. curvispina is a widely distributed and commonly abundant component of the invertebrate assemblages in shallow waters of southern South America. The experiments were repeated three times. The mean 48-h LC(50) value for H. curvispina was estimated at 0.066μg/l. H. curvispina represents a good model for exotoxicological risk assessment.
