Potencialidade da contaminação por metais pesados procedente da industria galvânica no município de Juazeiro do Norte/CE

Abstract

Gem veneer industry generates a polluted efluente that can cause damages to the environment when discarded in an inadequate form. Actually, the residual water should be treated, in form to acquire an established physiochemical profile for organs adapt that it disposes about patterns and conditions for release of liquid efluentes generated by pollutant sources. The great concern regarding polluted efluentes with heavy metals occurs of the fact that the same ones represent a danger for the animal life. The Cariri Region, in the south of Ceará, own a located industrial pole in the Triângulo Crajubar, which includes the cities of Crato, Juazeiro of the North and Barbalha, and, consequently, it suffers with the environmental degradation generated by this sector. This study shows the potential of contamination for heavy metals and cyanide originating the Gem veneer industry browsed in the municipal district of Juazeiro of the North. The results show that a great amount of heavy metals exists in the residual water generated by the industry of galvanoplastia of Juazeiro of the North, mainly the metals Copper and Zinc and smaller amounts observed for nickel and cadmium in function of the formulation of each eletrolitic solution.
