Zinc isotope systematics in snow and ice accretions in Central European mountains

Popis výsledku v původním jazyce

Zinc (Zn) pollution negatively affects human and ecosystem health. We quantified atmospheric Zn inputs at six remote mountain-top locations in the Czech Republic (Central Europe), and used delta Zn-66 isotope ratios to identify Zn from different pollution sources. The study sites were located at an elevation of approximately 1000 m near the state borders with Germany and Poland. During two winter seasons (2009-2010), over 400 samples of vertical deposition (snow) and horizontal deposition (ice accretions) were collected. Zinc pollution levels were generally low. Zinc concentrations in snow and ice accretions were less than twice as high in the east, compared to the west. Across the sites, over 90% of Zn was present in a weak-acid soluble form. Zinc concentrations were 5 times higher in ice accretions, which formed from small droplets originating in the basal cloud layer, rich in pollutants, than in snow. In contrast, droplets resulting in snow formation were larger and scavenged less p
