The Swedish Environmental Protection Agency has laid down limit values for ten metals in liming products destined for acid lakes and wetlands. However, there are many more metals which may be present in the liming products. Another project, Leaching Properties of Natural Aggregate (RVF report 2006:6 and Värmeforsk report 961) showed that the three liming materials included in this project contained measurable concentrations of many more metals. Particularly the concentration of arsenic was comparably high. The present project aimed to give an overview of the metal concentration on liming products. Almost all stable elements have been analysed with a semi-quantitative scanning method. The result shows that 48 elements are present in measurable concentrations and 16 are not. The high concentrations of arsenic from the Leaching Properties project could however not be repeated.
