| Description |
PESTAB. beta-HCH (beta-BHC) was purified by recrystallization and 5 mg were reacted with 125 ml autoclaved distilled H2O for various time intervals at 25 +- 1C. The filtrate was examined by GLC and was found to contain alpha, beta, gamma (lindane) and delta-BHC isomers as well as some unidentified compounds. An instantaneous dehydrochlorination of beta-BHC in distilled water was also observed. The acetone extract of the filtrate was further shaken for 4 days and bioassay toxicity studies were performed on mosquito and flour-beetle larvae and on houseflies. The toxicity of the extract was significantly greater than equal amounts of untreated beta-BHC in acetone. The results indicate beta-BHC may isomerize in aquatic environments and therefore, may be a potential source of more biologically active isomers in the environment.
