Catchment runoff in industrial areas exports legacy pollutant zinc from the topsoil rather than geogenic Zn

Popis výsledku v původním jazyce

In highly industrialized, densely populated parts of CentralEurope, mobilization of legacy Zn pollution from forest ecosystems maynegatively affect the quality of water resources. To test this hypothesis, wedetermined the 66Zn/64Zn isotope ratios of 15 Zn reservoirs and fluxes in anacidified, spruce die-back affected mountain-slope catchment in northernCzech Republic. The delta66Zn values of precipitation, organic horizon, andrunoff were statistically indistinguishable. In contrast, delta66Zn values of bedrockorthogneiss and mineral soil were significantly different from delta66Zn values ofrunoff. The magnitude of within-site Zn isotope fractionations appeared to berelatively small. Despite the large potential source of Zn in bedrock, runoffexported mostly young pollutant Zn that had been temporarily stored in theorganic horizon. This conclusion was corroborated by comparing Zn input−output mass balances in the polluted northerncatchment and in a relatively unpolluted catchment situated 2 km to the south. Seven-times higher Zn export via runoff at thenorthern site was controlled by a combination of 10-times higher atmospheric Zn input and five-times higher DOC leaching,compared to the southern site. In industrial areas, atmospherically deposited Zn is leached from headwater catchments in a directanalogy to leaching of highly toxic pollutant Pb
