Contaminant emissions as indicators of chemical elements in the snow along a latitudinal gradient in southern Andes
Abstract The chemical composition of snow provides insights on atmospheric transport of anthropogenic contaminants at different spatial scales. In this study, we assess how human activities influence the concentration of elements in the Andean mountain snow along a latitudinal transect throughout Ch...
