| Abstract: | The former mercury mining districts in Platina (Rheinland-Pfalz, Germany) are now overgrown with a more-or-less dense cover of vegetation. Much of the area is in agricultural use. Cultivated fields around the community of Mörsfeld have been analyzed. The mercury concentration in soil samples exceeds the threshold values set for sewage sludge by up to 10. 000 fold. Wheat grain cultivated in this area has a Hg content of up to 100 times higher than the threshold values set by the WHO/FAO. The accummulation was found to be organ specific and varies by species. The highest Hg concentration was measured in mosses, the lowest in leaves of shrubs. |
