Abstract
Thus, several samples from a contaminated riverine system in vicinity to a former HCH production site in Central Germany were analyzed. This area adjacent to the industrial megasite Bitterfeld-Wolfen is known for elevated concentrations of various organic industrial pollutants as legacy of decades of industrial activity and subsequent deposition of chemical waste and emission of waste effluents. In environmental compartments of this riverine system, several isomers of HCH related compounds were detected comprising the two lower chlorinated species tetrachlorocyclohexene (TeCCH) and pentachlorocyclohexene (PeCCH) and the higher chlorinated species heptachlorocyclohexane (HpCCH). Except for the uppermost soil of an analyzed riparian wetland, concentrations of these compounds were low. Detected isomers in sediment, water, and soil samples correlated and dominant isomers of PeCCH and HpCCH were observed in the alluvial deposits. Comparisons with industrial HCH waste revealed isomeric patterns similar to patterns found in soil samples. Therefore, the application of HpCCH as an indicator of industrial HCH pollution is suggested.
