Chemical analysis of mosses 1990–2015

This report describes the spatial distribution and chronological development of pollutants in mosses in Switzerland. The series of studies has been carried out every five years since 1990 within the scope of the Convention on Long-Range Transboundary Air Pollution. In Switzerland, pollution caused by Ag, As, Cd, Hg, V and Pb (reductions of between 51 % and 88 %) and by Al, Co, Cr, Fe, Mo, Ni, Sb, Tl and Zn (reductions of between 31 % and 49 %) has strongly decreased over the past 25 years. Concentrations of nitrogen in mosses have barely changed since 1995. PAH levels were mostly lower in 2015 versus 2010 (when measurements were first carried out). Generally speaking, higher levels are found in southern Switzerland, while the lowest levels occur in the central Alps.
