Long-range transboundary air pollution and sensitive ecosystems: international approaches

Private initiatives such as carbon credit trading can support public policies aimed at reducing greenhouse gas emissions. Agroscope and ETH Zürich examined factors which influence the effectiveness of such initiatives.

The occurrence of per- and polyfluoroalkyl substances (PFAS) is widely documented in soils, water bodies, drinking water and foods. An analysis by Agroscope ranks the contribution made by plant-protection products and other sources to groundwater contamination with PFAS.

Nitrogen from agriculture, traffic, and industry enters soils and water bodies via the air. A new study shows for the first time that increased nitrogen deposition has a negative impact on bird populations – even in semi-natural habitats.
