ABSTRACT
beta-HCH was shaken with distilled water at 25 +/- 1 degree C for different time intervals and filtered. The ether extract of the filtrate on analysis by gas liquid chromatography showed the presence of four isomers, alpha, beta, gamma and delta, besides other compounds, thereby indicating isomerization of the beta-isomer in aqueous solution. Further, the ether extract, when dried and dissolved in acetone, showed high toxicity to mosquito larvae, flour beetle larvae and house-flies thereby indicating conversion of the inert beta-isomer to more toxic forms corroborating GLC analysis. Acetone solution of pure beta-HCH was found nontoxic against the insects tested.
