Abstract

Contaminated soil and water remediation is a high impact challenge in the world. This environmental problem became significant only in the last decades. Remediation with plants is an environmentally friendly solution to clean the surface layers of soil from heavy metals, but the pollutants can mean danger in plants too. After gathering plant and soil samples from a closed mining area in Hungary, Zn, Cu, Cd, Pb, Cr, Ni, and Co concentration was measured by ICP spectrometry using a Varian 720 ES-type spectrometer. To determine the risk of the biomass, the distribution of metals was analyzed in plant part, such as twigs, sprouts and leaves; thick bough; bole without bark; and bark. Based on the results, the metallic elements (Zn, Cu, Cd, Pb, Cr, Ni, and Co) accumulate in smaller branches of trees and shoots and the tissues of the cortex responsible for the transport of nutrients, therefore the gathering of all plant parts after remediation is required to prevent environmental pollution.
