TI  - Passive atmospheric sampling of organochlorine pesticides, polychlorinated 
      biphenyls, and polybrominated diphenyl ethers in urban, rural, and wetland sites 
      along the coastal length of India.

AB  - India is of prime interest due to the large past and ongoing use of pesticidal 
      persistent organic pollutants (POPs). Rapid dissipation of POPs to the atmosphere 
      in the tropical climate of India infers an atmospheric outflow of these 
      chemicals. Yet data on POPs in the atmosphere of India are sparse. Passive air 
      samplers consisting of polyurethane foam disks were therefore deployed 
      concurrently at 18 locations and exposed for 6 weeks from July 30, 2006, to 
      September 26, 2006, along the coastal length of India to screen for POPs in the 
      atmosphere. The sampling sites were selected to form categories of urban, rural, 
      and background (mangrove/wetlands) locations. Derived air concentrations (pg/m3) 
      ranged as fellows: the sum of 28 PCB congeners, 120-1080; DDTs, 16-2950; HCHs, 
      66-5400; chlordanes, 9-921; endosulfans, 0.45-1120; and the sum of 9 PBDE 
      congeners, 1-181. The highest levels of all the detected POPs (except endosulfan) 
      were observed at the urban sites, indicating the dominant areas of usage and 
      emissions. An urban-rural composition fractionation of PCBs indicates their 
      atmospheric movement. The gamma-HCH levels were more than double those of 
      alpha-HCH, indicating the sporadic use of lindane. DDT concentrations were 
      elevated, at levels comparable to China, but with much higher percentages of 
      p,p'-DDE, reflecting a more 'weathered' feature. Although no dicofol use was 
      recorded in India, the o,p'-/p,p'-DDT ratios were observed to be even higher than 
      in China. Chlordanes showed high trans-/cis-chlordane (TC/CC) ratios, indicative 
      of the current use of technical chlordane and a contribution from heptachlor 
      usage.
