Abstract/Contents:"Seventy-nine samples of fungi were determined for mercury content from 13 sites in Helsinki, Finland. The highest concentrations were found in lawn decomposers (range 0.12-72 ppm/dry wt.). The mercury contents were much lower in wood decomposers and in mycorrhizal fungi (ranges 0.05-0.67 and 0.01-1.3 ppm). The mercury contents were much higher in lawn decomposers in the centre of the city than in the suburbs. In other fungi this could not be shown. The consumption of lawn decomposer fungi growing in Helsinki is not recommended, because the mercury content of about half of the 17 samples collected from the lawns in the centre of the city exceeded 0.5 ppm. According to Finnish norms, fish containing more Hg than this should not be eaten more often than once a week. None of the wood decomposers or mycorrhyzal fungi, however, exceeded this norm."
