“…The levels of PBCs contamination in the soils studied were much lower than the recommended limits of 25 mg/kg and 33 mg/kg set by the Canadian Soil guide [37], and the US EPA [38], respectively. The levels were comparable to levels detected in soils in Linfen city, China [39], lower than those found in soils elsewhere in Bahrain [40], Moscow region [41], Switzerland [42], Belarus [43], New York [44], Shanghai [45], but higher than those found in Poland [46].…”

Polychlorinated biphenyls (PCBs) in tropical soil samples from the Central Region of Ghana, and their variation with the soil characteristics were assessed. The soil characteristics of seventy eight samples were first determined. The PCBs was extracted with (1:1) hexane:acetone mixture, and then the extract treated with concentrated H 2 SO 4 , 5% KMnO 4 and copper. The extract was finally eluted from a silica gel column with hexane:dichloromethane (97:3 v/v), and the PCBs analyzed using a gas chromatograph equipped with 63 Ni electron capture detector (GC-ECD model CP 3800). The composition of PCBs homologous in the soils followed the order: hexa-PCBs (31.89%) > penta-PCBs (23.98%) > tri-PCBs (18.47%) > tetra-PCBs (13.67%) > hepta-PCBs (11.99%). The PCB congener profile in the study area was PCB 28 > PCB 153 > PCB 138 > PCB 52 > PCB 101 > PCB 180 > PCB 118. The mean concentration of the PCB congeners (dry matter basis) was PCB 28, 2.27 ± 2.436; PCB 52, 1.84 ± 2.27; PCB 101, 2.17 ± 2.52 µg/kg; PCB 118, 0.83 ± 0.89 µg/kg; PCB 138, 0.99 + 0.91 µg/kg; PCB 153, 1.18 ± 1.11 µg/kg and PCB 180, 1.18 ± 1.19 µg/kg. The mean concentrations of ΣPCBs were 9.15 ± 0.52 µg/kg for the surface soils (0 -10 cm), 7.55 ± 0.56 µg/kg and 7.82 ± 0.55 µg/kg for the 10 -20 cm and 20 -30 cm sub-surface soils respectively. Significant but weak correlations were observed between PCBs and the soil pH, moisture, and exchangeable base. The coefficient of determination for all significant correlations was between 6.6% and 18.75%.

“…The concentration, source, and congener pattern of PCBs in soils have been studied by many scientists all over the world. In China, PCB concentrations in soils of Dalian, Taiyuan, Linfen, Harbin, Hong Kong and so on have been reported in recent years (Zhang et al, 2007;Fu et al, 2008a;Wang et al, 2008;Fu et al, 2009;Ma et al, 2009). However, most of these studies focused on the concentration of PCBs in urban soils, only a few research reported the PCB levels in rural soils (Chen et al, 2008;Shen et al, 2009;Wang et al, 2009;Wu et al, 2010b).…”

The soil quality in rural area may associate with the health of local residents and food safety. This study aimed to investigate the spatial and vertical distribution of PCBs in rural soils of Beijing, and the source identification of PCBs and toxic equivalency calculation of dioxin-like PCB congeners were conducted. The mean of total PCB concentrations in Beijing rural soils was 11.01 ng g -1 . The congener profiles were predominated by lowly chlorinated congeners such as Di-CBs, Tri-CBs and Tetra-CBs. No significant difference of PCBs concentrations was observed between plain and mountain areas, and PCBs were slightly accumulated in the surface soils of Beijing rural area. Long-range transport of volatile PCB congeners was also an important source in addition to local sources of PCBs from electronic products. Toxic equivalency concentrations of dioxin-like PCB congeners met Canadian soil quality guidelines for agricultural soils, indicating a lower risk of PCBs to human health.

Polychlorinated biphenyl (PCB) was detected as isomer groups (congener numbers 28, 52, 101, 118, 138, 153 and 180) in the coastal water and sediment of four stations around Shadegan wetland protected area in the northwestern part of the Persian Gulf. Total PCB concentration range was 8-375 ng/L in water and 3.4-50.2 μg/g in sediment. Concentration of different congeners and chromatogram indicates that the source of PCB in this area can be Clophen A60; it used for long time in Iranian electronic industries. Other chlorinated hydrocarbons such as lindane, DDT and their metabolites were also present in the samples.
