  • Quantification of Dioxins in the Sieved Fraction of River Sediment

説明

Dioxin pollution of aquatic sediments has been one of the important environmental problems in Japan.Grain size distribution and organic constituents may play important roles in dioxin contents in sediments, which have not been well investigated. This paper aimed to quantify dioxins (PCDDs/Fs and co-PCBs) in sieved surface sediment fractions obtained from Kizu and Sumiyoshi River in Osaka, Japan. The samples were prepared and analyzed following “the Manual of the Survey and Measurement of Dioxins in Sediment”(Environment Agency in Japan, 2000) and “Method for determination of tetra-through octa-chlorodibenzo-p-dioxins, tetra-through octa-chlorodibenzofutans and coplanar polychlorobiphenyls in industrial water and wastewater”(Japanese Standards Association, 1999) The results showed that TEQ concentrations of dioxins increased with increasing the contents of Ignition Loss (IL) in the sediment fractions. Thus, reporting dioxin contents in sediments without considering grain size distribution may be erroneous, and conventional sediments. This information can be useful for effective remediation of dioxin-contaminated sediments.
