Resumos

Uma série de experimentos foi realizada com o objetivo de estabelecer a CL50 para o molusco gastropode Neritina virginica em relação ao hexaclorociclohexano conhecido, comercialmente, como BHC (Europa) e HC (EUA). As concentrações usadas de BHC variaram entre os limites de 1,120 a 2,000 mg/l e os experimentos tiveram a duração de 96 horas. O valor obtido de CL50 96 horas para Neritina virginicafoi de 1,482 mgBHC/l.

The LC50 of Neritina virginica (gastropod) to hexaolorocyclohexane (C6H6Cl6) was determined. A series of experiments was prepared during a period of 96 hours using different hexaclorocyclohexane concentrations. The LC50 to Neritina virginica was 1,482 mg hexaclorocyclohexane/l.
