- •
PAHs in cryoconite from seven glaciers of the Tibetan Plateau were presented.
- •
The highest ΣPAHs contents were found in the southeastern Tibetan Plateau.
- •
Total organic carbon and grain size were minor factors affecting PAHs values.
- •
Low toxic equivalent quantity of PAHs in most of glaciers suggested a limited biological risk.
