英文摘要	polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (pcdd/f) were analyzed in surface sediments and top soils collected from 30 sites in daliao river basin. the concentrations of pcdd/f ranged from 0.28 to 29.01 ng teq kg(-1) dw (mean value, 7.45 ng teqkg(-1) dw) in sediments, and from 0.31 to 53.05 ng teq kg(-1) dw (mean value, 7.00 ng teq kg(-1) dw) in soils. pcdd/f pollution in sediments from the mid- and downstream sections of hun river was found to be relatively heavy, and the levels of pcdd/f contamination in paddy soils were generally higher than those of upland soils. using multivariate statistical analysis, the pcdd/f homologue and congener profiles of all soil and sediment samples were compared with those of suspected pcdd/f sources. the results showed that, pcdd/f contamination in most sediments of hun river should mainly originated from the production of organochlorine chemicals, while metal smelting was the important potential source of pcdd/f in the drainage area of taizi river. pcdd/f contamination in paddy soils should be simultaneously attributed to the polluted water irrigation and the organochlorine pesticide application.
