Short description: The catchment of Lake Maggiore is the area most widely affected by acid deposition in Italy. Trend analysis was performed on long-term series of chemical data on atmospheric deposition in four streams draining forested catchments and four high mountain lakes. Improvements in water quality due to decreasing sulphate concentration and increasing pH were detected. Atmospheric deposition, however, is still providing a large and steady flux of nitrogen compounds, causing increasing nitrogen saturation in forest ecosystems and increasing nitrate levels in rivers. Other important factors controlling water acidification and recovery include the weathering of rocks and soils, which may be influenced by climate change, and the episodic deposition of Saharan calcareous dust, which contributes significantly to base cation deposition.
