The Study of Environment Levels of Dioxins and Furans in a Typical Regional

Abstract:

Ambient air, tree bark, soil and river sediments were sampled by the investigation of the background levels from a typical regional without industrial pollution in southern China. The WHO-TEQ of PCDD/F (WHO-2005) were 0.0366±0.0126 pg/Nm3 in ambient air, 0.8863±0.6088 pg/g in tree bark, 3.2435±0.0651 pg/g in soil and 1.4795±0.1917 pg/g in river sediments, respectively. The levels of PCDF in ambient air and tree bark were generally a little lower than the PCDD levels, but the values of PCDD were tens, even thousands times high than the PCDF in the soil and river sediments. The scope plot of PCA indicated that the congener profiles of PCDD/Fs in the tree barks, soil and river sediments of Hezhou were similar, but different from the samples of ambient air.
