Soil amendments for immobilization of potentially toxic elements in contaminated soils: A critical review

Environment International, Journal Year: 2019, Volume and Issue: 134, P. 105046 - 105046

Published: Nov. 12, 2019

Soil contamination by potentially toxic elements (PTEs) has led to adverse environmental impacts. In this review, we discussed remediation of PTEs contaminated soils through immobilization techniques using different soil amendments with respect type element, soil, and amendment, efficiency, underlying mechanisms, field applicability. such as manure, compost, biochar, clay minerals, phosphate compounds, coal fly ash, liming materials are widely used immobilizing agents for PTEs. Among these amendments, biochar attracted increased interest over the past few years because its promising surface properties. Integrated application appropriate is also recommended maximize their use efficiency. These can reduce PTE bioavailability in diverse mechanisms precipitation, complexation, redox reactions, ion exchange, electrostatic interaction. However, properties pH, clay, sesquioxides organic matter content, processes, sorption/desorption key factors governing amendments' efficacy soils. Selecting proper yield cost-effective fulfill green sustainable principles. Furthermore, long-term stability immobilized compounds impacts cost effectiveness should be considered before application.

Prediction of Soil Heavy Metal Immobilization by Biochar Using Machine Learning

Environmental Science & Technology, Journal Year: 2022, Volume and Issue: 56(7), P. 4187 - 4198

Published: March 15, 2022

Biochar application is a promising strategy for the remediation of contaminated soil, while ensuring sustainable waste management. heavy metal (HM)-contaminated soil primarily depends on properties biochar, and HM. The optimum conditions HM immobilization in biochar-amended soils are site-specific vary among studies. Therefore, generalized approach to predict efficiency required. This study employs machine learning (ML) approaches biochar soils. nitrogen content (0.3–25.9%) rate (0.5–10%) were two most significant features affecting immobilization. Causal analysis showed that empirical categories efficiency, order importance, > experimental properties. this presents new insights into effects can help determine enhanced
