ABSTRACT
There is a lack of information regarding persistent organic pollutants (POPs) in soil from Slovakia. This paper reports the concentrations of 17 polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), 12 dioxin-like polychlorinated biphenyls (dl-PCBs) and 6 indicator PCBs associated with 32 soil samples collected in 2007 from areas in the vicinity up to several kilometres from four selected industrial PCDD/F sources in Slovakia and one background area. The results show that the total WHO(1998)-PCDD/F/dl-PCB-TEQ concentrations varied from 0.34 to 18.05 pg g(-1) dry weight (dw) and the average total TEQ concentrations in samples collected at the Sala, Kosice, Krompachy and Dubová areas were 3.18, 2.64, 7.80, and 3.19 pg g(-1)dw respectively. The average of the total WHO(1998)-TEQ values in three soil samples representing the background Starina area was 0.66 pg g(-1) dw. The predominant contaminants among 2,3,7,8-substituted PCDD/Fs, dl-PCB, and indicator PCBs was OCDD, PCB 118, and PCB 153 respectively. The major contributors to the TEQ were 2,3,4,7,8-PeCDF, PCB 126, 1,2,3,7,8-PeCDD, PCB 156 and 1,2,3,4,7,8-HxCDF+1,2,3,4,7,9-HxCDF in descending order.
