FACTORS LIMITING EFFICIENCY OF PHYTOEXTRACTION AT MULTI-METAL CONTAMINATED SITES

摘要

The paper is based mostly on results from 3 field experiments and pot experiments with additional references to the literature. The three field experiments of reference will be first presented. Then the site characteristics (including the local climatic and edaphic conditions as well as the nature and extent of the contamination), the plant characteristics and the aspects related to the legislative background will be presented successively. It should be remembered that all these aspects may interact and thus are not truly independent parameters.
