Natural attenuation mechanisms of heavy metals in compacted soils: Case study from south wales, united kingdom

Research output: Contribution to journalArticle

Abstract

Clay liner has been utilised in landfill sites to contain hazardous pollution such as heavy metals from polluting the environment. The natural attenuation mechanisms between the heavy metals and active soil components were investigated using leaching column experiments. The results indicated that heavy metals were retained very rapidly in all soils due to various attenuation processes. Most of the heavy metals were retained almost instantly at the top of the soil columns. Selective sequential extractions (SSE) have been utilised to determine the main attenuation processes involved in these soil samples. The results showed that heavy metals were mainly retained via precipitation process in association with carbonates and amorphous oxides hydroxides in these soil samples.
