ABSTRACT
Accumulation of heavy metals in soil-water-plant continuum as a result of irrigation with metals contaminated effluent has been studied. Effluents being used for irrigating agricultural fields had normal pH 7.3-7.5, high Cr and Cl content as per the prescribed standards for irrigation. Among the heavy metals, buildup of total Iron was highest (9 times) and that of cadmium (1.3 times) was lowest in effluent irrigated soil as compared to tubewell irrigated soils. In most of the hand pump water samples, Pb, Cd and Cr were above the permissible limits for drinking. Bioaccumulation of Pb and Cr in vegetables was found to be above the critical concentrations for plant growth while Pb and Cd were above the prescribed limit in the diet of animals. Most of the heavy metals were above the maximum allowable limit in soil.
