ABSTRACT

The remediation of several contaminated industrial soils from heavy metals emitted among others by anthropogenic mining and metallurgical activities is an acute problem in today's reality when strict governmental regulations are imposed to heavy metals industries on environmental aspect of their processes. However effective and economic physicochemical technologies for remediation of these sites remain complicated and costly. A new alternative remediation technique is a special biotechnological technique called phytoremediation. This is based on the ability of some plants to accumulate very high concentrations of metals from soils and thus providing the basis for a remediation of the contaminated sites. This technique has several advantages compared to the sophisticated physicochemical techniques of soil remediation such as low cost and the lack of creation of other wastes. Furthermore plants can accumulate metals to such levels that the mineral recovery maybe feasible even in conventional smelting or refinery operations. This work, as part of a bigger project, focuses on the phytoremediation of industrial sites contaminated with nickel and on nickel phytoextraction techniques. Several plants that have high ability of nickel accumulation have been investigated and the most promising species that can be used for phytoremediation purposes in nickel contaminated soils has been suggested. Atomic spectrometry and biological studies have also been carried out in order to control and optimize these phytoremediation and phytoextraction processes
