Abstract

Abstract: In recent decades, naturally growing mosses have been used successfully as biomonitors of atmospheric deposition of heavy metals and nitrogen. Since 1990, the European moss survey has been repeated at five-yearly intervals. In 2010, the lowest concentrations of metals and nitrogen in mosses were generally found in northern Europe, whereas the highest concentrations were observed in (south-)eastern Europe for metals and the central belt for nitrogen. Averaged across Europe, since 1990, the median concentration in mosses has declined the most for lead (77%), followed by vanadium (55%), cadmium (51%), chromium (43%), zinc (34%), nickel (33%), iron (27%), arsenic (21%, since 1995), mercury (14%, since 1995) and copper (11%). Between 2005 and 2010, the decline ranged from 6% for copper to 36% for lead; for nitrogen the decline was 5%. Despite the Europe-wide decline, no changes or increases have been observed between 2005 and 2010 in some (regions of) countries. Highlights: In 2010, heavy metal and nitrogen concentrations in mosses were determined at up to 4400 sites across Europe. Moss concentrations complement deposition measurements at high spatial resolution. For most metals, concentrations in mosses have significantly declined since 1990. Heavy metal pollution remains high in (South-)eastern Europe. Nitrogen pollution remains high in the central European belt. Abstract : Heavy metal pollution remains high particularly in (south-)eastern Europe, whereas nitrogen pollution remains high in the central belt of Europe.
