摘要:

This study describes the effect of sunlight on α‐ and γ‐isomers of hexachlorocyclohexane (HCH) in aqueous media with or without soil fulvic acid (SFA). Under identical conditions, in distilled water alone, the α‐HCH degrades at a slightly slower rate than the γ‐isomer. The rates of disappearance of α‐ and Y‐HCH are nearly identical in high and low concentrations of SFA solutions. The rate of depletion of these isomers is seasonal dependent. A possible conversion of the γ‐isomer to the α‐form to a small extent is indicated.
