Description

1. Introduction In the last decades, the raising water pollution has led to the increase in research concerning the toxic and non-toxic effects of metal contamination. As a result, the wastewater of industrial origin can play a negative role as to the utilization of a receptor water body. The bioactive cations, especially present in aquatic environments, can lead to undesirable physical, chemical and biological alterations of the water. In particular, the aquatic beings of economic interest do not resist the presence of rejected materials, the effluent becoming a direct carrier of the elements harmful to human health. Moreover, the accumulation of certain elements in the food chain can reach dangerous trophic levels [1]. The presence of heavy metals in these industrial residues is an accomplished fact [2].
