[more ▼] In numerous places, mining and ore treatment activities have generated environmental contaminations which endanger ecosystem viability and/or human health. In some places, the ecological pressure induced by the metal contaminations allowed the development a specific flora, fromwhich candidates for phytoremediation may be selected. A survey of edaphic conditions prevailing for plant growing in contaminated areas around metal smelters has been conducted in belgian calaminary sites (Zn, Pb, Cd contaminations) and in the Katanga province of RDC (Cu contaminations). As the processes generated by the modifications of the soil environment may affect the form of a trace element, that is its distribution through various pools, we investigated physical and chemical fractionation of some metallic trace elements (Cu, Zn, Pb, and Cd) in soils and compared temperate and tropical cases. The results stress the need for a typology of the contaminations that takes into account the classical pedological parameters, even if contaminated sites are far from classical soil environment. The variability of edaphic properties that can occur within small distances is also an important point to consider when planning rehabilitation operations.

[more ▼] A specific flora has developped in Central Africa on soils which are naturally rich in Cu and Co. Mining and ore treatment activities in the Katanga province (RDC) have generated contaminations which do endanger ecosystem viability and/or human health. A survey of edaphic conditions prevailing for plant growing in natural metalliferous outcrops, the « copper hills », in mining sites (quarries), and in contaminated areas around metal smelters, is conducted as a first stage of a phytoremediation-based research program. Soluble, available and total content in some metallic trace elements have been measured. The first results show a relatively high heterogeneity inside and between sites. But the main finding is related to the very different nature of contamination between the three types of sites. This point constitutes an additionnal difficulty that should be taken into account for the selection of metallophytic species from the copper hills or the quarries in order to vegetalize a site contaminated by atmospheric fall outs from metal smelters in Lubumbashi.
