Abstract

In this report, results are presented of a study on the occurrence of polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) in samples of soil, collected from suspected spots at seven locations in the vicinity of Amsterdam. From these areas it was known that small-scale (illegal) incineration of scrap wire and scrap cars might have resulted in contamination with PCDDs and PCDFs. A total of twenty samples, including five duplicates, was subjected to chemical analysis. Isomer specific analyses were performed at the Laboratory of Environmental and Toxicological Chemistry of the University of Amsterdam. Dioxin levels are expressed in ng 2,3,7,8-TCDD-equivalents per kg of dry material (ng I-TEQ/kg dry weight).
