  • Title: Analytical study of heavy metals of industrial effluents at Jaipur, Rajasthan (India).
    Author: Singh V, Singh Chandel CP.
    Journal: J Environ Sci Eng; 2006 Apr; 48(2):103-8. PubMed ID: 17913185.
    Abstract:
    Heavy metals contamination has been recognized as a major environmental concern due to their pervasiveness and persistence. These heavy metals are not biodegradable, hence there is a need to develop such a remediation technique, which should be efficient, economical and rapidly deployable in a wide range of physical settings. For the characterization of heavy metals of various industrial effluents, some heavy metals, like Arsenic, Cadmium, Chromium, Copper, Iron, Manganese, Nickel, Lead and Zinc were analyzed. The results exhibited that As, Cd, Cr and Pb were not found in any studied wastewater samples, while some of the following heavy metals ranged from: Cu (0.0 - 1.0 mg/L), Fe (0.1 - 0.4 mg/L), Mn (0.0 - 0.4 mg/L), Ni (0.01 - 0.07 mg/L) and Zn (0.68 - 60.84 mg/L). Copper, Iron, Manganese and Zinc were found above the standard limit recommended by IS: 3307 (1977). However, Nickel was found below the regulated safety values for all studied samples.
