Environmental pollution is one of the most important current concerns for human daily life. The present study aims to evaluate the heavy metals and ecological risk factors of agricultural soil profile in Attur taluk, Tamil Nadu, India using geochemical methods. Attur region has become a famous place for tapioca based industries (sago industries). These industries release large volumes of heavy metal wastes into the adjoining agricultural lands. In this study 18 soil samples were collected for physico-chemical and heavy metal analysis to assess the ecological risk estimation. The level of pollution in the study area was assessed using ecological risk factors, such as contamination factor (CF), pollution load index (PLI) and geo-accumulation index (Igeo). The results indicated that study areas' samples numbered 4 (Karumantur), 13 (Valayampathy) and 17 (Karadipatti) are contaminated which might be due to the continuous release of heavy metals of arsenic and copper containing sago industrial effluent into the soil. Soil management is needed for the study area to maintain sustainable environment.
