摘要

To investigate the environmental levels and profiles of PCDD/Fs, samples of ambient air, soil and river sediment were collected from a typical regional without industrial pollution in southern China. The results showed that the mean PCDD/F concentrations samples were 0.0053±0.0054 pg/Nm~3 in air, 1.9075±0.0562 pg/g in soil and 1.1422±0.0144 pg/g in sediment, respectively. The results also showed that PCDFs were predominant in all air samples, and it was opposite in the soil and sediment. The PCA indicated that the congener profiles of PCDD/Fs in the soil and river sediments were similar, but different from the samples in air.
