Immobilization Remediation of a Heavy Metals Contaminated Soil: A Case Study of Dump Site at Bangalore, India

Assessment of the application of two amendments (lime and biochar) on the acidification and bioavailability of Ni in a Ni-contaminated agricultural soils of northern Colombia

“…Which, in parallel, decreases the bioavailability of PTM's (Bolan et al 2003). Lime application is a strategy that increases soil pH and reduces the bioavailability of metals through precipitation mechanisms (e.g., by forming carbonates) (Ali et al 2020;;López et al, 2022;Sumalatha et al 2022).…”

“…Which, in parallel, decreases the bioavailability of PTM's ( Bolan et al., 2003 ). Lime application is a strategy that increases soil pH and reduces the bioavailability of metals through precipitation mechanisms (e.g., by forming carbonates) ( Ali et al., 2020 ; López et al., 2022 ; Sumalatha et al., 2022 ). However, it has been demonstrated that the incorporation of these materials is not effective in increasing soil resistance to acidification, thereby lime soils treated can be susceptible to re-acidification ( Shi et al., 2018 ).…”
