Health Risk Assessment due to Heavy Metals in Cow Pea Cultivated in Sanganer using Textile Waste Water

The present study was carried out to estimate the concentration of heavy metals (Zn Cu, Ni, Cd, Cr, Pb and Co) in Cow pea (Vigna unguiculata) collected from different agricultural fields located in Sanganer, Jaipur. Atomic absorption spectrophotometer was used to determine the concentrations of heavy metals. The present study aims at determining human health risks associated with food chain contamination by heavy metals caused by industrial effluent water used in irrigation. The plants accumulated Zn concentration as high as 15.708 mg/gm, Cu 8.878 mg/gm, Ni 6.186 mg/gm, Cd 5.446 mg/gm, Cr 7.505 mg/gm, Pb 6.595 mg/gm and Co 5.858 mg/gm. Results revealed that the average concentrations of all metals in the cow pea was found in order of their abundance as Zngreater than Cugreater than Crgreater than Pbgreater than Nigreater than Cogreater than Cd.
