空气和树叶样本（桉树属）和Pinus massoniana Lamb.）从中国南方的电子废物和参考站点收集，并分析了Dechlorane Plus（DP）和两种脱氯DP。空气中的DP浓度为13.1-1794 pg/m（3）的电子废物的网站和0.47-35.7 pg/m（3）的参考网站，这表明电子废物的回收是一个重要的DP的环境来源。植物DP，浓度为0.45-51.9纳克/克干重在电子废物网站和0.09-2.46纳克/克在参考网站，表现出类似于空气DP的时间模式，除了松针在参考网站。DP的空气-植物交换可用二室模型描述。在电子废物现场的大多数空气和植物样本中测量了抗Cl（11）DP。空气和植物中抗Cl（11）DP与抗DP的比值可能表明植物优先吸收脱氯DP而不是DP。(C)2011爱思唯尔有限公司保留所有权利。
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.
