A method for investigating in-situmethylation and mobility of mercury has beendeveloped and applied to forest soil. The methodis based on additions of stable 199Hgisotopes to forest soil plots followed bysampling and analysis of isotope ratios of tot

In the covered catchment at Lake Gardsjon, the reversibility of acidification and the effects on Hg output of a decreased deposition of Hg and MeHg have been investigated since 1991. A first indication of a decreased from the covered catchment, cause

Mercury concentrations in lacustrine macroinvertebrates were concurrently studied in eight remote Swedish forest lakes of differing dystrophy, acidity, and eutrophy. The aim was to assess the influence of ecological factors (taxon, habitat, and feedi

Critical Review of "Metals Environmental Risk Assessment Guidance for Metals" (MERAG)
Critical Review of "Metals Environmental Risk Assessment Guidance for Metals" (MERAG)
Risk assessment of metals may need specific guidance in how to handle natural background, essentiality, and long historical use of metals. It may also be necessary to take bio-availability into account. The aim of the present project was to criticall
