N2 - Polyurethane foam (PUF) disk passive air samplers were deployed concurrently at five sites across Kolkata megacity and the rural mangrove wetland of Sundarban (UNESCO World Heritage Site) between January-March in 2014. Samples were analyzed for hexachlorocyclohexanes (HCHs), dichlorodiphenyltricholoroethanes (DDTs), polychlorinated biphenyls (PCBs) and, polybrominated diphenyl ethers (PBDEs) using gas chromatography and mass spectrometry (GC-MS). Derived air concentrations (pg/m(3)) for Kolkata ranged: for Sigma alpha- and gamma-HCH between 70 and 207 (114 +/- 62), Sigma 6DDTs: 127-216 (161 +/- 36), Sigma(7)PCBs: 53-213 (141 +/- 64), and Sigma 10PBDEs: 0.30-23 (11 +/- 9). Low values for all the studied POPs were recorded in the remote area of the Sundarban site (with the exception of DDTs: o,p'-DDT and p,p'-DDT), where Sigma 4DDTs was 161 +/- 36. In particular, the site of Ballygunge, located in the southern part of Kolkata, showed the highest level of all the metabolites/congeners of POPs, suggesting a potential hot spot of usage and emissions. From HCHs, alpha-/gamma-HCH isomers ratio was low (0.67-1.96) indicating a possible sporadic source of lindane. y-HCH dominated the HCH signal (at 3 sites) reflecting wide spread use of lindane both in Kolkata and the Sundarban region; however, isomeric composition in Kolkata also suggests potential technical HCHs use. Among DDT metabolites, both o,p'-DDT and p,p'-DDT shared the dominant percentages accounting for 26-46% of total DDTs followed by p,p'-DDE (similar to 12-19%). The PCB congener profile was dominated by tri- and tetra-CI at the southern and eastern part of Kolkata. These results are one of the few contributions that reports air concentrations of POPs, concurrently, at urban and remote villages in India. These data are useful to assess atmospheric pollution levels and to motivate local and regional authorities to better understand the potential human exposure risk associated to urban areas in India.
