Special Issue Information
Dear Colleagues,
The occurrence of potentially toxic elements (PTEs), including As, Cd, Hg and Pb, in the environment represents an issue of global concern for aquatic systems, with a general decline in environmental quality in both freshwater and marine systems, posing risks to the health of communities that strongly rely on them.
Over the past five decades, the global water demand has tripled, driven by demographic growth and industrialization. However, this rapid increase in the uptake of water has not been accompanied by a similar improvement in infrastructures designed to ensure the quality of effluents that return to rivers, lakes, or seas. Moreover, water quality is frequently threatened by multiple pollution sources, and conventional treatment systems struggle to remove such a broad spectrum of contaminants, thus limiting clean water sources.
In recent years, knowledge of green remediation technologies for PTE-contaminated waters and wastewaters has rapidly grown, and at present, many treatment processes appear to be demonstrably feasible at the field scale. Innovative, eco-friendly, and economically feasible strategies have been developed and successfully applied. Among these are processes based on bioremediation (using microbes, plants, algae), biosorption (microbial surface binding), the use of biochar, natural or synthesized sorbents from waste materials and/or industrial by-products, and nanomaterials, and green amendments like calcined clay for metal stabilization. To reduce the environmental impact of these technologies, they are often integrated with renewable energy and smart technologies for sustainable, low-cost cleanup of real aquatic systems.
In this Special Issue, we invite submissions exploring the development of green technologies without creating new waste by-products and increasing energy demand, tackling the issue of remediation of PTE-contaminated waters and wastewaters. Survey papers and reviews are welcome.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules 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 2700 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.
