Pollution status, health risk assessment of potentially toxic elements in soil and their uptake by in peri-urban of Ora-Eri, south-eastern Nigeria.

Pollution monitoring of potentially toxic elements (PTEs) in a typical peri-urban area in Ora-Eri, Nigeria has been unchecked. Thus, unified evaluation process was developed to assess the pollution load index and potential health risk to inhabitants in mapped regions. The environmental risk was evaluated using contamination factor, geo-accumulation index and Nemerow integrated index.
