| 英文摘要 | chlorinated paraffins (cps) are industrially produced in large quantities in the liaohe river basin. their discharge inevitably causes environmental contamination. however, very limited information is available on their environmental levels and distributions in this typical industrial region. in this study, short chain cps (sccps) were analyzed in sediments, paddy soils, and upland soils from the liaohe river basin, with concentrations ranging from 39.8 to 480.3 ng/g dry weight. a decreasing trend in sccp concentrations was found with increasing distance from the cities, suggesting that local industrial activity was the major source of sccp contamination. a preliminary sediment inventory of sccps indicated approximately 30.82 tonnes of sccps residual in the sediments from the liaohe river. the average discharge of sccps was estimated to be about 74.4 mg/ronne industrial wastewater. the congener group profiles showed that the relative abundances of shorter chain and lower chlorinated. cp congeners (c-10-cps with 5 or 6 chlorine atoms) in soils in rural areas were higher than in sites near cities, which demonstrated that long-range atmospheric transportation could be the major transport pathway. environmental degradation if sccps might occur, where higher chlorinated congeners could dechlorinate to form the lower chlorinated congeners. |
