High concentrations of heavy metals in beech forest understory plants growing on waste heaps left by Zn-Pb ore mining

This study investigated (1) concentrations of pollutants such as As, Cd, Pb, Tl and Zn, as well as Ca, Fe and Mn, in soils developed on old heaps of waste rock localized in beech forests (2) concentrations of these elements in shoots and roots of forest herbaceous species – null Mycelis muralis , null Melica nutans null and null Mercurialis perennis , and in leaves of young null Fagus sylvatica null trees growing on the heaps (3) ratios of...
