The concentrations of POPs were twice as high in plain in comparison to hilly areas. DDTs and HCHs were most frequently detected in the air samples. High levels of ∑26PCBs were linked to highly urbanized and industrial areas. The legacy POPs represent a negligible health risk through inhalation of air. Backward trajectory confirm air masses transport from India and Bay of Bengal.
