Short summary
Do the water bodies in the Tibetan Plateau (TP) act as a sink or secondary source of organic pollutants (OPs)? To answer this question, atmospheric processes of OPs over a large lake on the TP were quantified. We found that the lake was a net sink of hexachlorocyclohexanes (HCHs) and most polycyclic aromatic hydrocarbons (PAHs), but it turned into a secondary source of phenanthrene, coinciding with the melting of lake ice.
