Abstract :
PCDD/Fs (polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans) and PCBs (polychlorinated biphenyls) in soot dust, fume and contaminated air with burning plastic floor and electronic scrap (E-wastes) were sampled employing semi permeable membrane devices (SPMDs). It was found that the emitted PCDFs were dominant compared to PCDDs collected from samples. However the PCDD/Fs and PCBs congener profiles were different between soot dust, fume sample and contaminated air sample. The total amounts of PCBs were much higher than that of PCDD/Fs, but the contribution of them to the WHO-TEQ was less than that of PCDD/Fs. The total amounts PCDD/Fs, PCBs and WHO-TEQ is quite high in soot dust, fume sample than that in contaminated air sample.
