This study reports the first investigation of polychlorinated naphthalenes (PCNs) in air and soil samples from ecologically important sites of the Indus River Basin, Pakistan. The concentrations of ∑39-PCNs in air and soil were found in a range between 1–1588 pg m−3 and 0.02–23 ng g−1 while the mean TEQ values were calculated to be 5.4E−04 pg TEQ m−3 and 1.6E+01 pg TEQ g−1, respectively. Spatially,...
Levels of polychlorinated biphenyls (PCBs) were assessed in surface soils and passive air samples from the Indus River Basin, and the influential role of black carbon (BC) in the soil–air partitioning process was examined. ∑ 26 –PCBs ranged between 0.002–3.03pgm −3 and 0.26–1.89ngg −1 for passive air and soil samples, respectively. Lower chlorinated (tri- and tetra-) PCBs were...
