Abstract
SummaryThe PCDD congeners 1,2,3,4,6,7,8-heptachlorodibenzo-p-dioxin (HpCDD) and octachlorodibenzo-p-dioxin (OCDD) were analysed in five sewage sludge samples by the proposed micro method. The cleaned-up sample extracts were analyed by GC-ECD and confirmed by GC-MS. For quality assurance of the proposed method two sewage sludge samples of a UBA collaborative study and a certified soil sample fortified with definite HpCDD and OCDD concentrations were analysed. The results are comparable with the analysed and certified PCDD values.
