Abstract
São apresentados os resultados de bioensaios com larvas de Artemia salinacolocadas em misturas de γBHC e HgCl2, a fim de se compararem os efeitos das mesmas com aqueles obtidos quando essas duas substancias atuam isoladamente. A CL50 para o yBHC foi quase que o dobro do valor para o HgCl2. O efeito da primeira dose foi observado para aproximadamente 16% da população (CL16), enquanto que, para o γBHC, o foi em 2,3% da população (CL2,3). Assim, as doses subseqüentes foram mais efetivas para o HgCl2 que para o γBHC. A dose efetiva 50% (ED50) ê mais ou menos igual para o γBHC e para o γBHC + HgCl2, mas em doses altas o YBHC seria mais efetivo, enquanto que em doses baixas a mistura e que o seria.
Results of bio-assays using Artemia salina larvae in γBHC-HgCl2 mixture are presented. The results obtained are compared with those obtained using the two chemicals separately. The LC50 for γBHC was almost double that for HgCl2. The effect due to the primary dose of HgCl2 was observed for approximately 16% of the population (LC2.3) while for γBHC the population percentage was 2.3 (LC2.3). As a consequence, subsequent doses were more effective for HgCl2 than for γBHC. The effective dose 50% (ED50) is about the same for γBHC and for γBHC + HgCl2 mixture, though in higher doses BHC would be more effective, while in smaller doses the mixture would predominate.
