Survey of PCDDs and PCDFs in air and soil around various incinerators in Korea, 2003-2007

To investigate the levels of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) pollution in soils and air around incinerators, a total of 574 soil and 48 air samples were collected around 22 incineration facilities in Korea from 2003 to 2007. The concentrations of PCDD/Fs in the flue gases and air ranged from 0.01 to 21.50 ng I-TEQ Sm(-3) and 0.0002 to 9.95 pg I-TEQ Sm(-3), respectively whereas concentrations in soils ranged from n.d. to 153.23 pg I-TEQ g(-1) dw. The average value was 8.14 pg I-TEQ g(-1) dw in soil samples.
