Short summary
As Nepal is a tropical country close to the Himalayas, it is essential to investigate concentration levels and long-range transport potential of persistent organic pollutants (POPs) in its cities to assess whether these pollutants can contaminate the high Himalaya. We found high concentration and long travel distance (> 1000 km) of dichlorodiphenyltrichloroethane and hexachlorocyclohexane in the atmosphere of Nepalese cities, suggesting Nepal can be an important regional source region for POPs.
