TL;DR: Passive air samplers consisting of polyurethane foam disks were deployed concurrently at 18 locations and exposed for 6 weeks along the coastal length of India to screen for POPs in the atmosphere, and chlordanes showed high trans-/cis-chlordane (TC/CC) ratios, indicative of the current use of technical chlordane and a contribution from heptachlor usage.

TL;DR: Comparisons with the limited data available from studies conducted in 1989 suggest general declines of HCHs and DDTs for most regions, but high values of α/β-endosulfan at Chennai, Mumbai and Goa suggest ongoing usage.

TL;DR: There was a general decline in PFC concentration from urban, rural, to remote locations and generally the FTOHs were the most abundant, followed by 8:2 FTO in China and Japan and by the sulfonamides in India.

TL;DR: In-depth studies are needed to understand the fate of these compounds particularly in the developing nations and the associated adverse health impacts of BPA due to prolonged exposure.

TL;DR: Estimated daily intake shows that some infants are exposed to OCs to a greater extent, particularly HCHs than the guideline standard, and no association between concentrations of OCs and demographic characteristics such as parity and age of mothers was observed.
