摘要：
Air and foliage samples (Eucalyptus spp. and Pinus massoniana Lamb.) were collected from e-waste and reference sites in South China and analyzed for Dechlorane Plus (DP) and two dechlorinated DPs. DP concentrations in the air were 13.1-1794 pg/m(3) for the e-waste site and 0.47-35.7 pg/m(3) for the reference site, suggesting the recycling of e-waste is an important source of DP to the environment. Plant DP, with concentrations of 0.45-51.9 ng/g dry weight at the e-waste site and 0.09-2.46 ng/g at the reference site, exhibited temporal patterns similar to the air DP except for pine needle at the reference site. The air-plant exchange of DP could be described with the two-compartment model. Anti-Cl(11) DP was measured in most air and plant samples from the e-waste site. The ratios of anti-Cl(11) DP to anti-DP in the air and plants may indicate the preferential uptake of dechlorinated DP by plant compared with DP. (C) 2011 Elsevier Ltd. All rights reserved.
