Abstract

The content of 21 organochlorine pesticides were studied in vegetation samples of a highly contaminated area by isomers of hexachlorocyclohexane (HCH) located close to a former industrial area in Galicia (NW Spain). Five species of plants were collected at different points of the contaminated area and the different parts of the plants were separated in order to study differences in accumulation capabilities. Samples were extracted employing microwave energy followed by a clean-up step using solid phase extraction and finally determined by GC-ECD. The results obtained show that the most abundant pesticides are HCHs isomers, being the main isomers beta-HCH and alpha-HCH in all samples whereas delta-HCH and gamma-HCH were at lower levels. Some other pesticides such as p,p'-DDT, p,p'-DDD and p,p'-DDE were also present in much lower amount in some of the samples. Several degradation products of HCH were also identified in some samples by GC-MS.
