The heavy metals are probably the most harmful and insidious pollutants because of their non-biodegradable nature and hence to assess whether the effluent irrigation r`as contributed for
the heavy metal accumulation in the soil, present study was undertaken at Pallipalayam in
Tamil Nadu where paper mill effluent irrigation is in vogue for more than 25 years.
Reprosontative soil samples of surface (a-30 cm depth) and subsurface soil (30-60 cm depth)
from the fields, which were under different periods of effluent irrigation. viz. more than 25
years,15 years,12 years, 9 years and control (no effluent), were collected and analyzed for
heavy metals, viz. Cu, Zn, Pb and Cd by atomic absorption spectrophotometer. The study revealed
that though there is heavy metal accumulation in the soil, it is below the permissible limit. But
continuous effluent irrigation tends to accumulate heavy metals in the soil and hence suitable
soil amendment sr`ould be applied.
