Special Issue Information

Dear Colleagues,

This Special Issue aims to explore the occurrence, migration, transformation, accumulation, and effects of pollutants on wastewater treatment and aquatic systems. This Special Issue provides in-depth and systematic cross-disciplinary research on the release and traceability of environmental pollutants, toxicity assessment, novel detoxification technologies, environmental behaviour, and policy development. The research results can provide theoretical support and a scientific basis for the control and risk assessment of pollutants (nitrogen, phosphorus, heavy metals, toxic organic matter, emerging pollutants, etc.). This Special Issue focuses on the assessment of water quality and pollutant behaviour, including, but not limited to, the following topics:

  1. The transformation of pollutants in degradation units or Earth’s water environment.
  2. Research on toxicity sensors for toxic and hazardous chemicals.
  3. Efficient purification processes and mechanisms of highly toxic and hazardous chemicals.
  4. Community interactions and the genomic expression of microorganisms under the stress of toxic and hazardous chemicals.
  5. Fate and risk assessment of toxic and hazardous chemicals in environments.

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. Toxics is an international peer-reviewed open access monthly journal published by MDPI.

A biological treatment is the core process for removing organic pollutants from industrial wastewater. However, industrial wastewater often contains large amounts of toxic and harmful pollutants, which can inhibit the activity of microorganisms in a treatment system, precipitate the deterioration of effluent quality, and threaten water ecological security from time to time. In most of the existing anaerobic biological treatment processes, toxic effects on microorganisms are determined according to the amounts of end-products of the biochemical reactions, and the evaluation results are relatively lacking. When microorganisms contact toxic substances, changes in biological metabolic activity precede the accumulation of reaction products. As sensitive units, electroactive microorganisms can generate electrical signals, a change in which can directly reflect the toxicity level. The applications of electroactive microorganisms for the toxicity monitoring of wastewater are very promising. Further attention needs to be paid to considering the appropriate evaluation index, the influence of the environment on test results, mechanisms, and other aspects. Therefore, we reviewed the literature regarding the above aspects in order to provide a research foundation for the practical application of electroactive microorganisms in toxicant monitoring.
