AB  - The lower stretch of the perennial transboundary river Ganga is known as the 
      Hooghly River (HR) in India. Despite the strict ban, HR has been evidenced with 
      residues of pesticidal persistent organic pollutants (POPs) from primary and 
      secondary sources. Hence surface water sampling and passive air sampling (PAS) 
      were conducted along the urban and suburban transects and discharge points to 
      study the fate of pesticidal (POPs along the HR. Excluding the discharge points, 
      the mean concentration of hexachlorocyclohexane (HCH), 
      dichlorodiphenyltrichloroethane (DDT) and endosulfan (ENDO) were 6 ng/L, 4 ng/L 
      and 36 ng/L in surface water and 888 pg/m(3), 1689 pg/m(3) and 429 pg/m(3) in 
      atmosphere respectively. Percentage composition and diagnostic ratios strongly 
      suggest ongoing use of technical HCH, DDT and endosulfan. Elevated endosulfan in 
      surface water has been related to its usage during fishing. Except for p,p'-DDE, 
      alpha-Endo and beta-Endo, fluxes at the air-water interface showed net deposition from 
      air to water for all the OCPs in urban and suburban transects. The estimated 
      eco-toxicological risk assessment showed risk on lower trophic organisms due to 
      DDT and lindane mostly at the discharge points. Endosulfan can pose potential 
      risk to the edible fishe species in the HR.
