CHEMICAL ANALYSIS OF HEAVY METAL CONTAMINATION IN RIVER YAMUNA (IN SPECIAL REFERENCE TO DISTRICT MATHURA U.P.)
Keywords:

Abstract
The heavy metals, which are toxic at low concentrations find their way into animals and humans through air, drinking water and food; and, can reach higher concentrations which may become poisonous due to bioaccumulation. Heavy metals concentration in Yamuna river water at Mathura U.P., Cadmium (Cd) value was found to be ranged from ND to 0.052 mg/L. The mean concentration of Arsenic (As) ranged from 0.007 to 0.103 mg/L. Lead (Pb) value varied from 0.009 to 0.130 mg/L. Chromium (Cr) content in water ranged from 0.014 to 0.252 mg/L. The Nickel (Ni) concentration ranged from 0.010 to 0.144 mg/L with the lower value obtained during the post-monsoon. Copper (Cu) varied from 0.029 to 0.189 mg/L. The concentration of Zinc (Zn) in water varied from 3.733 to 20.788 mg/L. The results revealed that heavy metals except Copper (Cu) and Mercury (Hg) were beyond the permissible limits as per Indian standard for drinking water
