Special Issue Information

Dear Colleagues,

The invention of new chemicals or modification of existing chemical structures for the better quality of life in all domains of chemistry on an everyday basis led to the synthesis and usage of various new chemical compounds across the globe. Further, already existing and new evolving chemical compounds are synthesized and released into markets and human usage without the prior evaluation of their fate and toxic effects in the environment. Many chemical pollutants have been reported to be persistent, bioaccumulative, and toxic in various environmental matrices, globally. Detection, analysis, monitoring, toxicity, and life-cycle assessments of persistent pollutants in all environmental compartments including wastewater, surface water, groundwater, and soil is crucial to maintain the quality of water and ecosystems. At the same time, mounting evidence of the existence and accumulation of various persistence pollutants at trace levels has emphasized the demand for advanced research on the fate of persistent pollutants in the environment.

This Special Edition of Water will address the analysis and impacts of emerging and persistent environmental contaminants on various environmental compartments. It will cover all aspects of removal/degradation technologies of persistent pollutants including chemical, physical, and biological treatment methods. Research and review articles covering all parts of the world 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 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. Water 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 2600 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.

Within our therapeutic drug arsenal, antibiotics are of significant importance and are widely used in huge amounts to medicate, e.g., bacterial infections in humans and animals. Regarding the more than 10 types of antimicrobial drugs, the highly important orally taken β-lactams typically include dry suspension formulations. In many cases for this formulation, even after usage according to specification, residues remain in the prepared dry suspension bottle, which is often cleaned at home and the contents are flushed down into domestic wastewater. This plausible practice adds to the fact that, e.g., amoxicillin can be found in river waters, and is to be monitored in the EU, as given by resolution 2008/105/EG article 8b. When imported into the environment, β-lactam antibiotics can cause severe ecological problems, and equally importantly, therapeutic applications of these antibiotics are endangered by the forced development of pathogenic resistance. To avoid these issues, we developed and validated a fast, simple, robust, and cost-effective method using a 1 M sodium hydroxide solution to effectively hydrolyze and inactivate β-lactam residues. In this paper, we strongly propose a procedure involving pharmacists to take back residue of β-lactam dry suspension formulations. Subsequently, qualified pharmaceutical staff could inactivate β-lactam residue in the laboratory by the proposed method, and then dispose of the mixture into wastewater. Full article
