Response of atmospheric deposition and surface water chemistry to the COVID-19 lockdown in an alpine area.

The effects of the COVID-19 lockdown on deposition and surface water chemistry were investigated in an area south of the Alps. Long-term data provided by the monitoring networks revealed that the deposition of sulfur and nitrogen compounds in this area has stabilized since around 2010; in 2020, however, both concentrations and deposition were significantly below the average values of the previous decade for SO and NO. Less evident changes were observed for NH and base cation.

Article Synopsis
- Concerns are rising about the increasing chloride (Cl) levels in freshwater systems, particularly in northern regions, affecting lakes and rivers.
- A study analyzed 25 years of data from several Italian lakes, highlighting rising sodium (Na) and chloride concentrations, particularly in Lake Maggiore, with an upward trend since the early 2000s.
- The main sources for these trends are identified as road de-icing salt and wastewater treatment plant discharge, though current chloride levels do not pose immediate threats to water quality or aquatic life.
A Working Ring Test (WRT) was organised in the framework of the EU Regulation (EC) No 2152/2003 ("Forest Focus") and of the UN/ECE Program "ICP Forests" to evaluate the overall performance of the laboratories monitoring atmospheric deposition and soil solution in European Forests. Seven natural samples of atmospheric deposition and soil solutions and 5 synthetic solutions were distributed to 52 laboratories, which analysed them using their routine methods. Thirteen variables are considered in this paper: pH, conductivity, calcium, magnesium, sodium, potassium, ammonium, sulfate, nitrate, chloride, total alkalinity, total dissolved nitrogen and dissolved organic carbon.

- Studies of the inorganic carbon cycle in natural waters help understand biological productivity and buffering capacity through measurements of total inorganic carbon, alkalinity, and dissolved carbon dioxide.
- A new ion chromatography method utilizes electrolytic generated hydroxide eluent to measure total inorganic carbon directly by converting all forms to carbonate for easier detection.
- The method shows good repeatability and accuracy when compared to traditional calculations, effectively describing total inorganic carbon distribution in various surface waters, including alpine lakes and rivers.
