Maps containing data collected in the moss surveys from 1990 to 2010 are available here. Maps display the mean heavy metal (mg kg-1) and nitrogen (% mass) concentrations per 50 by 50km EMEP grid cell.
Summary data per survey year and graphs of trends in heavy metal concentrations across Europe are available here.
Methodology and discussion of the results for each year can be found in the survey reports on the Thematic Reports page. Note: all data and maps are copyrighted to ICP Vegetation.
