The first survey of persistent organic pollutant (POP) concentrations in air across several Indian agricultural regions was conducted in 2006-2007. Passive samplers comprising polyurethane foam (PUF) disks were deployed on a quarterly basis at seven stations in agricultural regions, one urban site and one background site. The project was conducted as a sub-project of the Global Atmospheric Passive Sampling (GAPS) Network. In addition to revealing new information on air concentrations of several organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs), the study has demonstrated the feasibility of conducting regional-scale monitoring for POPs in India using PUF disk samplers. The following analytes were detected with relatively high concentrations in air (mean for 2006 and 2007, pg/m(3)): α- and γ-hexachlorocyclohexane (HCH) (292 and 812, respectively); endosulfan I and II (2770 and 902, respectively); p,p'-DDE and p,p'-DDT (247 and 931, respectively); and for the sum of 48 PCBs, 12,100 (including a site with extremely high air concentrations in 2007) and 972 (when excluding data for this site).
2006-2007 年，在印度几个农业区进行了首次持久性有机污染物（POP）空气浓度调查。在农业区的七个站、一个城市站和一个背景站，每季都部署了包含聚氨酯泡沫（PUF）圆盘的被动采样器。该项目是全球大气被动采样（GAPS）网络的子项目。除了揭示关于几种有机氯农药（OCPs）和多氯联苯（PCBs）的空气浓度的新信息外，该研究还证明了使用 PUF 圆盘采样器在印度进行区域规模的 POP 监测的可行性。以下分析物在空气中的浓度相对较高（2006 年和 2007 年的平均值，pg/m3）：α-和γ-六氯环己烷（HCH）（分别为 292 和 812）；硫丹 I 和 II（分别为 2770 和 902）；p,p'-DDE 和 p,p'-DDT（分别为 247 和 931）；以及 48 种 PCBs 的总和，包括 2007 年一个站点的极高空气浓度（12100，包括一个站点的极高空气浓度数据）和 972（当排除该站点的数据时）。
