    Long-term changes (1990-2015) in atmospheric deposition and runoff water chemistry of sulphate, inorganic nitrogen and acidity for forested catchments in Europe in relation to changes in emissions and hydrometeorological conditions

  • Original language description

    The International Cooperative Programme on Integrated Monitoring of Air Pollution Effects on Ecosystems programme studies effects of air pollution on ecosystems in forested catchments. We calculated site-specific annual input-output budgets for sulphate (SO4) and inorganic nitrogen (DIN = NO3-N + NH4-N) for 17 European ICP IM sites in 1990 to 2012. Temporal trends for input (deposition) and output (runoff water) fluxes and net retention/net release of SO4 and DIN were also analysed. Large spatial variability in fluxes of SO4 and DIN was observed, with the highest deposition and runoff water fluxes in southern Scandinavia and Central Europe and the lowest fluxes at more remote sites in northern Europe. A significant decrease in total SO4 (wet + dry) deposition and bulk deposition of DIN was found at 90percent and 65percent of the sites, respectively, and output fluxes of SO4 in runoff decreased significantly at 60percent of the sites. Catchments retained SO4 in the early 1990s, but this shifted towards net release in the late 1990s, showing that legacy deposits of atmospheric SO4 deposition are mobilized to drainage waters. Despite decreased deposition, TIN output fluxes and retention rates showed a mixed response with both decreasing (9 sites) and increasing (8 sites) trend slopes, and trends were rarely significant. In general, TIN was strongly retained in the catchments not affected by natural disturbances. The long-term annual variation in net releases for SO4 was explained by variations in runoff and SO4 concentrations in deposition, while variation in TIN concentrations in runoff was mostly associated with variation of TIN retention rate in catchments. Net release of SO4 from forest soils may delay the recovery from acidification for surface waters and continued enrichment of nitrogen in catchment soils poses a threat to terrestrial biodiversity and may ultimately lead to higher TIN runoff through N-saturation.
