Special Issue Information

Dear Colleagues,

We invite you to take part in a special issue of the MDPI  Journal “Sustainability” – ““Soil remediation and sustainability”

Soil pollution is one of the main global problems affecting ecosystems state and services provided by them. It has become one of the most serious environmental issues and involving enormous financial and social implications all over the world. International Soil Reference and Information Center (ISRIC) and the United Nations Environment Program (UNEP) estimated that more 22 million hectares had been affected by soil pollution (Oldeman, 1991). The main anthropogenic contaminants are the chemicals used in or produced as byproducts of industry, domestic, livestock and municipal wastes (including wastewater), agrochemicals, and petroleum-derived products. Recently, the United Nations Environmental Assembly adopted a resolution calling for accelerated actions and collaboration to address and manage soil pollution. Remediation of polluted soils is essential, therefore, at present, intensive research is being carried out aimed at developing new, scientifically based methods for the restoration of contaminated and disturbed soils.

The special issue “Soil remediation and sustainability” is devoted to the theoretical foundations and practical methods of contaminated soils remediation. The issue aims is provide a unique possibility to share studies, experience and perspectives in these main topics:

  • Mechanisms of interactions between organic and inorganic contaminants and soil components,
  • Effect of soil and environmental conditions on the mobility and bioavailability of toxicants,
  • Innovative methods and technologies of soils remediation,
  • Best Available Techniques (BAT) on polluted soils remediation,
  • New efficient and environmentally friendly sorbents for the immobilization of various pollutants,
  • The role of humic substances in the restoration of contaminated soils.

This issue is serving as a basis for future discussions on the problem of Soil Remediation and Sustainability. We hope that the methods and technologies described in this issue of the journal will be in demand by the business and authorities and widely implemented in practice of agriculture and environmental protection.

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. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

A washing ejector is a pre-treatment technology used to remediate contaminated soil by separating fine particles. The washing ejector developed in this study is a device that utilizes fast liquid jets to disperse soil aggregates by cavitation flow. The cavitation phenomenon is affected by the Bernoulli principle, and the liquid pressure decreases with the increase in kinetic energy. The cavitating flow of the fluid through the Ventrui nozzle can remove surface functional groups and discrete particles. The main methodology involves the removal of small particles bound to coarse particles and the dispersion of soil aggregates. Particle collisions occur on the surface soil, such as the metal phase that is weakly bound to silicate minerals. It was observed that the dispersed soil affected the binding of toxic heavy metals and the mineralogical characteristics of the soil. The quantity of oxides, organic matter, and clay minerals affected the properties of the soil. An almost 40–60% removal efficiency of total metals (As, Zn, and Pb) was obtained from the contaminated soils. After treatment by a washing ejector, the volume of fine particles was reduced by 28–47%. When the contaminants are associated with particulates, separation using a washing ejector can be more effective. Therefore, physical separation improves the removal efficiency of heavy metals from soil aggregates. Full article
