What is it about?

This work assesses the levels of heavy metals which are potential toxic elements (PTEs) in an an area where copper has been mined in ancient and modern times. All important heavy metals in soil are analysed using ICP-OES, a technique that determines the environmentally available heavy metals. Recommendations are made for possible approaches to remediation using microbes and plants.

Why is it important?

This is the first case study in a country where there are over 150 abandoned mines. Mines soils need remediation and ecological restoration.


This is only a part of major investigation which also deals with water contamination, microbial remediation using four bacteria isolated from the soil with capabilities of bio-accumulating copper and the plant Ricinus communis that can take up the copper in its root-system and still produce untainted shoots that can be utilized for the production of a value-added product namely castor oil.
