Résumé
The heavy metal pollution, mainly caused by mining-related activities over extended period of time, is imposing a severe threat to environments and human health. Environmental systems, including rivers and paddy soils, have been widely established as one of the key sinks of potentially harmful metals. Aiming to understand contamination sources and pathways of Zn in karst area, we studied the Zn concentration and isotope composition of river waters, sediments, mine tailings, paddy soils, dust and three soil profiles with different levels of Zn-pollution around a Zn-mine, southwestern China. The distinct Zn isotope compositions among tailing (-0.42 ± 0.02‰), dust (-0.24 ± 0.02‰), and geogenic soil (-0.16 ± 0.03‰) allowed for separation of anthropogenic-Zn from native Zn. In the plot of δ
