Degradation as a Loss Mechanism in the Fate of A-Hexachlorocyclohexane in Arctic Watersheds
Article Abstract:
Summary of the A-HCH ER results from detailed samplings taken during the final year of the 1992-1994 Amituk Lake study, and later field investigations. These reports focus on agricultural and industrial chemicals contamination of Canadian arctic ecosystems.

Toxaphene, chlordane, and other organchlorine pesticides in Alabama air
Article Abstract:
In this study, air samples in Alabama were gathered in January-October 1996 and May 1997 to review the seasonal variations of toxaphene and other OC pesticides. The study is broken down into an introduction, a discussion of the experiment and its results. Various tables and graphs accompany the article.

Enantioselective breakdown of alpha-hexachlorocyclohexane in a small Arctic Lake and its watershed
Article Abstract:
A study was conducted to analyze enantioselective degradation of alpha-hexachlorocyclohexane (alpha-HCH) in the Arctic by running water and snow samples from the region under gas chromatography. Enantiomeric ratios (ER) for alpha-HCH was agreed with the theoretical ER of 1.00 for intact alpha-HCH. Snow samples registered an ER of 0.98, with a deviation of plus or minus three. This is attibuted to active nonenzymatic degradation of water in Amituk Lake. The results suggests that the Arctic contains an efficient system of microbial degradation.
