摘要: Heavy metals are important environmental pollutants and their toxicity is a problem of increasing significance for ecological, evolutionary, reasons. Arachis hypogaea was grown in pots period of 30 days where the soils were treated with different effluent concentrations (25, 50, 75 100%) collected near an industrial area control was carried out. The distribution of heavy corresponding accumulations experimental crop investigated on 10, 15, 20, 25 30th day. Cr, Cu, Mn, Fe, Co, Ni, Pb, Cd and Zn plants soil samples analyzed by AAS technique. In Fe was high 100% at 25th days. It has been observed that 25% concentration, there growth root length, increase shoot germination percentage, Chl a, chl b, total chlorophyll content L. have increased upto 20th day (2.929, 1.607, 4.536 mg/g.fw) then decreased from day (1.670, 0.832, 2.149 mg/g. fw) onwards
