Special Issue Information

Dear Colleagues,

Heavy metal contamination of soils and water poses persistent threats to ecosystems, public health, and agricultural productivity. This Special Issue, 'Treatment and Restoration of Heavy Metal Pollution in Soil and Water: From the Ecological and Sustainable Perspectives,' emphasizes integrated remediation approaches that blend ecological restoration with sustainable development. It encompasses phytoremediation, microbial-assisted remediation, soil amendments, physicochemical treatments, and hybrid strategies designed to reduce toxicity, promote ecosystem recovery, and facilitate resource reuse.

While conventional remediation research often prioritizes technology over ecological integration, this issue seeks to bridge that gap by highlighting strategies that restore ecological balance and monitor sustainability outcomes. Contributions are invited to include life cycle assessments, sustainability metrics, long-term effectiveness, and socio-economic analyses. By focusing on multidisciplinary evaluations and field-level applications, the Special Issue advances the literature toward the development of measurable, sustainable interventions in heavy-metal-impacted environments.

Aligned with Pollutants' mission, this issue will deliver actionable insights for policymakers, environmental managers, and researchers, promoting resilient, cost-effective, and ecosystem-aligned remediation practices for long-term environmental stewardship.

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 250 words) can be sent to the Editorial Office for assessment.

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. Pollutants is an international peer-reviewed open access quarterly 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 1200 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.

Based on data from the literature in the Web of Science (WOS) and Scopus databases, this study collected 325 articles published between 2020 and 2025. Using Citespace software (version 6.4) to analyze publication volume, countries, institutions, disciplinary categories, and keywords, we examined research characteristics, hotspots, and bottlenecks in the field of ecological remediation for heavy metal pollution in mining area soils. Results indicate: (1) Publication volume in this field showed an upward trend from 2020 to 2024, accounting for 70.2% of this dataset being from the environmental sciences. Chinese scholars demonstrated significant dominance and high engagement, though interdisciplinary depth remained insufficient; (2) from 2020 to 2025, the research focus shifted from risk identification to precise remediation, forming a complete logical chain of ‘identification–remediation–optimization’. Green technologies (biological/combined remediation) emerged as mainstream approaches in integrated remediation. (3) A significant gap exists between research and practice. Many innovative technologies are costly and difficult for enterprises to bear, while low-cost techniques like ‘waste-to-waste treatment’ lack sufficient research and application, hindering large-scale implementation. This study reveals the current situation of ‘intense research but difficult application’ in the ecological remediation of heavy metal-contaminated soils in mining areas. The findings provide a scientific basis for technological innovation, practical implementation, and policy making. Full article
