“…Concentrations of lindane, PCB-28 and HCB are respectively 10, 2 and 0.5 ng·kg −1 at the plateau. Such levels are in agreement with the orders of magnitude experimentally observed on natural soils (Villanneau et al, 2009;Villanneau et al, 2011;Salihoglu et al, 2011;Barber et al, 2005) and show that the input data we have selected are relevant for such a study. Significant oscillations were observed in the top-soil concentration for lindane and HCB, but they are mitigated with the soil depth.…”

“…Covariance is showed here by the similar orientation of the vectors representing P 29 PCBs and TOC. Several previous studies had provided parameterizations for the relationship between PCB concentrations and TOC using data from global and regional scale surveys (Meijer et al, 2003;Salihoglu et al, 2011). TOC in the O-horizon and A-horizon ranged 3.9e44.6% with mean 26.8% and 2.0e26.4% with mean 10.9%, respectively.…”

“…5 Although PCBs have been banned in most parts of the world, they are continually released from old equipment. Polybrominated diphenyl ethers (PBDEs), one of the most important brominated ame retardants, are extensively used as ame retardants in electrical and electronic products.…”

Heavy metals and persistent organic pollutants polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) were analyzed in 34 surface soil samples collected from farmland and 7 soil or dust samples collected from the workshops in South China, where e-waste was dismantled using primitive techniques. The results show that Cd, Cu and Hg were the most abundant metals, in particular Cd pollution was serious in farmland soils, and the median concentrations in farmland soils were beyond the environmental quality standard for soils (China Grade II). A correlation between Cd, Cu, Zn, Pb and PCBs or PBDEs was significant indicating similar sources. Among the PCB congeners, high relative similarity was observed between the e-waste dump site soil (EW1) and Aroclor 1254, implying that the technical product Aroclor 1254 was one of the major sources of PCB contamination. High concentrations of PCBs in workshop dusts (D2 and D3) (1958 and 1675 mg kg À1 ) demonstrated that the workshops dismantling electrical wires and cables, electrical motors, compressors and aluminum apparatus containing PCBs in lubricants represent strong PCB emission sources to this area. Principal component analysis (PCA) and PBDE homologue patterns verify that farmland soils surrounding the e-waste recycling sites were enriched with lower brominated congeners, and the major source of PBDEs in dust samples might potentially be associated with the extensive use of deca-mix technical products as a flame retardant. The difference between e-waste soils, dusts and farmland soils can be observed in the PCA score plot of PCBs and PBDEs, and E-waste soils and dusts exhibited more diversity than farmland soils. Furthermore, a prediction of the particular kinds of pollution from different recycling activities through the analysis of each contamination and the connections between them was investigated. Environmental impactThe recent worldwide boom in electrical and electronic equipment is driving the dramatic growth of e-waste, and the recycling by primitive techniques in South China results in the contamination of the workplace and the surrounding environment by toxic metals and persistent organic pollutants. This study examined the distribution of heavy metals and organic compounds in surface soils and workshop dusts, associated with the contaminants and investigated any possible association between heavy metals and different homologue-groups of PCBs and PBDEs. The correlations of contaminants and principal component analysis of technical origin and environmental behaviors indicated the signicance of such recycling as an emission source of this area and veried the particular kinds of pollution from different recycling activities.
