A Study of Metal Distribution from Lignite Fuels Using Trees as Biological Monitors

摘要

Concentrations of five metals(Cd, Cu, Mn, Fe, Zn)were determined in tree leaves collected from an area with large coal-fired plants in Ptolemais, Macedonia, Greece. The analyses were carried out with flame atomic absorption spectroscopy. Mean heavy metal content in the tree leaves is, in descending Order, Fe>Mn>Zn>Cu>Cd. In Populus nigra and Salix Babylonica the dense piled leaves and the widespread root system Are the reasons for high heavy metal uptake. Conifer trees Pinus Nigua and Junjiperus arizona, which have a rough leaf surface, Also had elevated concentrations.
