Special Issue Information
Dear Colleagues,
Soil contamination with heavy metal(loid)s (HMs) is a widespread problem. Worldwide, more than 10 million sites are considered to have polluted soil, of which above 50% are contaminated with heavy metals (e.g., Cd, Cr, Pb) and/or metalloids (e.g., As). Due to HMs’ persistence, bioaccumulation, and toxicity, remediation actions in contaminated areas are still urgent. Two main remediation practices, i.e., immobilization and mobilization, have been adopted to reduce the hazardous effects of HMs and restore contaminated soil ecosystems. Immobilization with stabilization/solidification or assisted phytostabilization techniques decreases the mobility of HMs in soil and their bioavailability to plants, animals, and humans and reduces HM leaching into groundwater. Mobilization of HMs can include phytoextraction, electrokinetics, or soil washing/soil flushing technologies and results in permanent HM removal from soil. Considering the limitations of remediation techniques, immobilization processes are generally preferred for treating heavy metal contaminated soils. Although soil remediation with mobilization and immobilization of HMs has attracted intense interest in recent years, many areas still need to be developed. Thus, this Special Issue is seeking contributions that focus on the following:
- Innovative approaches to minimize the bioavailability and toxicity of HMs in soil;
- The effectiveness of mobilization and immobilization of HMs in multi-HM contaminated soils;
- Novel agents to immobilize or mobilize HMs in soils, including waste by-products, or modified or combined soil amendments;
- Inovative methods of incorporation of immobilising amenmdents to soil;
- Interactions between target HMs and (im)mobilizing agents; mechanisms of action of (im)mobilizing agents;
- Long-term sustainability of amendments in field conditions;
- Soil microorganisms in HM mobilization/immobilization in different soil environments;
- Monitoring HMs in soils remediated with immobilization and/or mobilization practices;
- Advanced techniques to examine the effect of HM immobilization and/or mobilization in different soils.
This Special Issue is open to research, case studies, or review papers that will contribute to advances in soil remediation based on HM immobilization and/or mobilization strategies.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Environmental Research and Public Health is an international peer-reviewed open access monthly journal published by MDPI.
