“…The OCP concentrations found in plants from different regions Table 3. In general, the concentrations of both HCHs and DDTs in plants were one order of magnitude higher in the present contaminated site than in other areas (Wang et al 2007;Lin et al 2008;Yi et al 2012;Tarcau et al 2013;Pan et al 2014). These findings confirm that the contaminated sites are significant sources of pollution if left untreated, resulting in local and regional plant contamination.…”

The contamination of organochlorine pesticides (OCPs) and hexachlorobutadiene (HCBD) in soils, plants, and terrestrial fauna from a former pesticide-producing area in Southwest China was investigated. High levels of OCP residues (RHCHs and RDDTs of 3.89-13,386 and 23.3-11,186 ng g -1 dw, respectively) were found in the soils within the producing factory, indicating that the former pesticide factory brownfield site poses a high environment risk and that effective soil remediation is needed. The OCP concentrations in soils surrounding the pesticide factory were 1-2 orders of magnitude higher than in the other agricultural areas from China. Grass, vegetables, and tree leaves from the surrounding areas of the point source showed moderate OCP pollution, which was likely to be causing potential negative impacts on terrestrial ecosystem. OCP levels in terrestrial species from the studied area including insects, free-range chickens and birds were moderate, and were generally within accepted safe levels.b-HCH was the most prevalent isomer, implying that hexachlorocyclohexane (HCH) residues were mainly derived from the degradation of technical HCH. The dichlorodiphenyltrichloroethane (DDT) profiles reflected obvious degradation of technical DDT. In the study area, the concentrations of HCBD were \0.02-5.59, 0.03-24.6 ng g -1 dw and 1.65-3.80 ng g -1 lw in soils, plants, and animals, respectively, which were relatively low and not sufficient to cause observable adverse biological effects.

“…However, much higher concentrations of HCB, DDTs and HCHs in soils around the research stations of east Antarctica (Negoita et al, 2003), and CHLs (sum of OxC, TC, CC, and TN, 3e599 pg g À1 dw) in soils from penguin colonies of east Antarctic coast (Roosens et al, 2007) have been reported. Higher levels of DDTs than HCHs in most soil and sediment may be attributed to larger amounts of DDT used in agricultural activities than HCH formulations (Tarcau et al, 2013), and to a less extent due to the differences in physicochemical properties (Table S2) that HCHs have higher biodegradability, lower lipophilicity and lower particle affinity compared with DDTs (Loganathan and Kannan, 1994). OCPs in the dropping-amended soil had a different distribution profile from the natural soil samples.…”

a b s t r a c tAntarctica is considered as a final sink of many persistent organic pollutants (POPs). This work aims to investigate the levels, distributions and potential sources of organochlorine pesticides (OCPs) with HRGC/ HRMS technique. Twenty-three OCPs were measured in various environmental matrices from King George Island, west Antarctica. The total concentrations (S 23 OCPs) were at quite low levels, ranging 93.6 e1260 pg g À1 dry weight (dw) in soil and sediment, 223e1053 pg g À1 dw in moss and 373e812 pg g À1 dw in lichen. Hexachlorobenzene (HCB), dichloro-diphenyl-trichloroethane (DDT) and its metabolites (especially p,p 0 -DDE) and hexachlorocyclohexanes (HCHs) were the main contaminants in all samples.Lower a-HCH/g-HCH and higher p,p 0 -DDE/p,p 0 -DDT ratios compared with the technical products indicated long-range atmospheric transport (LRAT) of recent lindane and aged technical DDT. Significant dependence of many OCPs concentrations on total organic carbon (TOC) was observed. Apart from LRAT, local biotic activities could also contribute and influence the spatial distribution of the contaminants.

“…Various types of vegetation have been used as natural sampling media to evaluate atmospheric pollution of SVOCs since the 1980s (Buckley, 1982;Eriksson et al, 1989). Lichens (Augusto et al, 2009;Blais et al, 1998;Cabrerizo et al, 2012;Schrlau et al, 2011;Yogui et al, 2011), mosses (Cabrerizo et al, 2012;Cipro et al, 2011;Wang et al, 2012;Yogui et al, 2011), tree bark (Salamova and Hites, 2010;Tarcau et al, 2013) and pine needles (Blais et al, 1998;Schrlau et al, 2011;Yang et al, 2008) are the most commonly used vegetation because of their high lipid content, large surface area and great seasonal availability. Lichens and mosses, due to lack of barrier structures and root-like structures, can directly absorb gas-phase, aerosol and particle-bound pollutants from the atmosphere (Kansri et al, 1990;Madl et al, 2010;Yogui et al, 2011) and integrate air contamination over time (Simonich and Hites, 1995).…”

Some research has reported an accumulation difference among the various air samplers (Schrlau et al, 2011;Tarcau et al, 2013;Yang et al, 2013). Schrlau et al (2011) compared the accumulation difference of SVOCs in lichen and XADpassive sampler, and indicated that lichens could accumulate more SVOCs with octanol-air partition coefficients of log Koa N 10, whereas XAD mainly accumulated gas-phase SVOCs.…”

• DDTs, endosulfans, HCHs and hexachlorobenzene predominated in all the samples.• High detection frequency of HBCDs was only observed in lichen samples.• Lichen concentrations of OCPs and PCBs increased with elevation in Tibetan Plateau.• Lichen is more suitable to reveal airborne SVOC contamination than moss.• SVOCs with log K OA (8-11) and log K WA (2-4) had high mountain contamination potential. a b s t r a c t a r t i c l e i n f o This study investigated a wide range of semi-volatile organic compounds (SVOCs), including 28 persistent organochlorine pesticides (OCPs), 18 polychlorinated biphenyls (PCBs), 13 polybrominated diphenyl ethers (PBDEs), and 3 hexabromocyclododecane (HBCD) congeners in lichen, moss and soil collected from the southeastern Tibetan Plateau, China. This allows research provides insight into elevation gradient distributions and possible cold trapping effects of SVOCs in this high mountain area, and compares lichens and mosses as air passive samplers for indicating SVOC occurrences. DDTs, endosulfans, HCHs and hexachlorobenzene predominated in all of the samples. Source analysis indicted that there were fresh inputs of DDTs and HCHs in the sampling region. Lichens and mosses shared commonalities in revealing the profiles and levels of SVOCs based on their lipidcontent-normalized concentrations. The concentrations of 12 OCPs and 14 PCBs in lichens were significantly linearly correlated with altitudes, whereas the correlations for mosses and soil with altitudes were insignificant. Both a frequency distribution diagram and the Mountain Contamination Potential Model indicated that SVOCs with specific values of log K OA (8-11) and log K WA (2-4) had relative high mountain contamination potential on the Tibetan Plateau.
