Special Issue Information
Dear Colleagues,
Eutrophication has become the primary water quality issue for most of the freshwater and coastal marine ecosystems in the world. As eutrophication becomes frequent and many eutrophic ecosystems have difficulties meeting the EU Water Framework Directive (WFD) criteria, the removal of phosphate and/or ammonium gains great importance in water treatment. In order to reduce the release flux of nutrients from contaminated sediments, various remediation strategies have been developed, such as [a] dredging, [b] precipitation of P by aluminum salts, [c] in situ chemical injection, [d] hypolimnetic oxygenation, and in situ capping. Among these approaches, P-inactivation agents are used for reducing sediment nutrient release rate by permanently blocking the release of N and P from the sediments. In situ capping, which involves the placement of a layer at the sediment–water interface to create a barrier between the sediment and the aquatic environment, is a potentially effective technology to stabilize sediments, minimize both re-suspension and transport, and reduce dissolved contaminant transport into overlying waters. This Special Issue will contribute to this objective by collecting articles addressing the development and application of innovative tools for eutrophication control and restoration of degraded ecosystems. Papers on restoration methods of eutrophic ecosystems, emphasizing remediation methods of internal nutrient release budget, will be considered. Papers involving the use of phosphate inactivation agents as a restoration tool, their ecotoxicity, their capacity, and application methods, as well as the individual results (in water quality, algal blooms, flora and fauna) in areas that have been implemented are also welcome. We invite you to contribute full papers, reviews, or communications. In all cases, the papers must demonstrate novelty and importance to the scope.

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.
