Special Issue Information

Dear Colleagues,

With industry development, environmental pollution with aromatic compounds, such as nitrophenols, chlorophenols, and polycyclic aromatic compounds, is constantly increasing. Due to their structure, these compounds are highly durable and resistant to biodegradation. At the same time, they are characterized by high toxicity to living organisms and threaten the proper functioning of biocenoses. We encourage researchers to submit original research papers and review articles, stimulating further efforts to develop strategies to reduce environmental pollution with toxic aromatic compounds and help remove them from contaminated sites.

Topics of interest for this Special Issue include, but are not limited to, the following:

  • Environmental effects of aromatic compounds;
  • Advanced oxidation processes (AOPs) as an effective method of removing arenes;
  • Sewage treatment plant (STP) processes for removing aromatic compounds;
  • Development of new methods to intensify the degradation of aromatic compounds;
  • Microbiological transformation and degradation of aromatic compounds;
  • Analysis of bioproducts from physicochemical and biological conversions of arenes.

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. 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.

The aim of this study was to elucidate all the degradation byproducts (DBPs) of bemotrizinol (BEMT) that are associated with sodium hypochlorite treatment. BEMT is a UV filter that is found not only in many personal care products, such as sunscreen and cosmetics, but also as an additive in plastics or clothing to protect them from damage that results from absorbed radiation. BEMT has been detected in wastewater, surface water, and some lake sediments, in quantities from a few ng/L to hundreds of ng/L, to such an extent that, today, it is considered an emerging pollutant. In this study, the UV filter was subjected to oxidation with sodium hypochlorite, which is an oxidant at the base of the disinfection process that is used in most wastewater treatment plants or in swimming pools. Using different chromatographic methods (CC, TLC, HPLC, and GC), the resulting DBP mixture was separated into its main components, which were then identified using one- and two-dimensional nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry. Nineteen DBPs were isolated, and a plausible reaction mechanism was proposed to explain how they were obtained. Full article
