摘要：In the present study investigation on impact of treated and partially treated industrial effluents on soil and agriculture produce has been carried out. The study find out that parameters (pH, TSS, TDS, BOD, COD, Chloride, Sulphate, Zn, Cu, Pb, Ni, Cr, Cd) of channel water of sampling station-I (8.12, 404 mgl-1, 2624 mgl-1, 122 mgl-1, 331.45 mgl-1, 808 mgl-1, 32.4 mgl-1 , 0.36 mgl-1 , 0.05 mgl-1, 0.03 mgl-1, 0.04 mgl-1, 4.55 mgl-1, 0.03 mgl-1) was higher than station-II (7.82, 215 mgl-1, 1737 mgl-1, 105 mgl-1, 265 mgl-1, 788 mgl-1, 29.7 mgl-1 , 0.31 mgl-1, 0.04 mgl-1, 0.03 mgl-1, 0.03 4.12 mgl-1, 0.02 mgl-1) . Waste water quality of stations I and II meet to exceed the Indian standard (IS: 2490) for BOD- 30 mgl-1, COD-250 mgl-1 and Cr- 2 mgl-1 for safe disposal of effluents into the surface water. During the course of study soil and agricultural produce has been collected from irrigation of treated or partial treated industrial effluent and analyzed for trace elements i.e. Fe, Zn, Cu, Pb, Ni, Cr and Cd. The trace elements showed different enrichment factor for soil as Cd 8.75(max), Cr 8.6, Zn 5.73, Ni 4.08, Fe 3.16, Cu 2.41, Pb 1.58(min). For plant samples collected at polluted site showed different enrichment factor of trace elements - 6.87 (Cr)> 6.04 (Zn)> 3.34 (Pb)> 3.05 (Cu)> 2.78 (Fe)> 2.30 (Ni)> BDL (Cd). The levels of trace elements concentration in spinach (max) (Fe821, Zn145, Cu19.84, Pb 18.04, Ni 10.1, Cr38.32, Cd0.88 µg/g) and in wheat (min) (Fe326, Zn102, Cu8.23, Pb 12.6, Ni 5.9, Cr21.5, Cd0.21 µg/g) grown on polluted soil were found more than the reference value of control sites in spinach (Fe257, Zn25, Cu6.98, Pb7.43, Ni4.13, Cr5.6, Cd BDL) , which may create chronic health problem to living being through food chain . The highest enrichment factor of agricultural produce (Efp- Fe-2.78,Zn-6.04,Cu-3.05,Pb-3.34,Ni-2.3,Cr-6.87,Cd-0) was found for the element of Cr and for soil, the highest enrichment factor (Efs- - Fe-3.16,Zn-5.73,Cu-2.41,Pb-1.58,Ni-4.08,Cr-8.6,Cd-8.75) was found for element of Cd respectively.
