Temporal trends and spatial distribution of sulphur and nitrogen deposition in the Czech Republic since 1900

Popis výsledku v původním jazyce

Central Europe was significantly affected by extremely high sulphur (S) and nitrogen (N) depositions in the past, which caused widespread forest decline, soil and water acidification and biodiversity changes. S deposition and to some extent, N deposition declined significantly since the 1980s and damaged ecosys-tems have begun to recover. Nevertheless, the present deposition of nitrogen is still above pre-industrial levels and might affect the future status of vulnerable N limited forest or grassland ecosystems. Despite documented changes in precipitation chemistry and emission rates since monitoring began in the 1970s, the analysis of spatial variability of S and N deposition over the Czech Republic and its historical recon-structions was limited. Therefore this study presents the temporal development and spatial variability of S and N depositions and will be carried out according to the method published by Oulehle et al. (2016). This method is based on the tight, coherent relationship between measured precipitation, SO4, NO3 and NH4 concentrations from 32 monitoring sites and the Czech and Slovak national emission rates of SO2, NOx and NH3 for the period 1994–2012. The application of the method suggests that with the estimated his-torical emission data gathered, that it will be effective in the long-term reconstruction and prediction of S and N deposition and will provide a useful tool for future adaptation strategies. We calculated S and N dep-osition for the years 1900, 1950, 1980, 1990, 2000 and 2010, in order to reveal national spatio-temporal changes. The results show a substantial decline in S and N deposition. In the year 2010, the deposition of S below forest canopies was lower by 70-90 kg/ha (throughfall deposition) and of N by 10-17 kg/ha in the high mountains on the northern Czech border than in the 1980.
