Dichloromyristic acid, a major component of organochlorine load in lobster digestive gland
Article Abstract:
A study aimed at examining the chlorinated compounds in lipid extracts of American lobster (Homarus americanus) is presented. The lobsters, which were captured in an industrial harbor near a pulp mill, yielded low chlorine content in their lipids. The experiment employed more reliable fractionation and analysis procedures such as neutron activation analysis, fractionation on a Sephadex LH-20 column and mass spectrometry, to explain the phenomenon. It was found out that chlorinated alkanolic acids make up most of the extractable organically-bound chlorine lipid samples.

Formation and spectroscopic investigation of two hexachlorobornanes from six environmentally relevant toxaphene components by reductive dechlorination in soil under anaerobic conditions
Article Abstract:
The degradation of six toxaphene congeners by reductive dechlorination in soil was investigated under anaerobic conditions. All compounds exhibited reductive removal of one chlorine atom from each geminal dichloro group in the C-2 position. The rate of dechlorination was highest for nonachlorobornanes, followed by octachlorobornanes and heptachlorobornanes. Two metabolites were formed from the reaction: 2-exo,5-endo,6-exo,8c,9b,10a- and 2-endo,5-endo,6-exo,8c,9b,10a-hexachlorobornane.
