Special Issue Information

Dear Colleagues,

Emerging organic contaminants are chemically stable and bioaccumulative and pose serious safety threats to a range of species. There is great concern over water contamination due to these compounds, since they are not completely removed and/or degraded by conventional water and effluent treatment processes and may not be biodegradable. The uncontrolled discharge of such substances into the environment exceeds their self-purification capacity, even at trace concentrations, and contributes to the accumulation of some of these contaminants at different environmental levels, which can lead to potentially harmful effects on aquatic environments and human health. For this reason, there is a need to develop and/or test techniques to efficiently treat these compounds in aqueous media.

This Special Issue on “Advances in the Analysis of Emerging Organic Contaminants” seeks high-quality papers focusing on the most recent advances in technologies for the removal or degradation of emerging organic compounds in aqueous media.

Possible topics include, but are not limited to, the following:

  • Treatment processes using alternative, efficient, and low-cost methods;
  • Development of materials from industrial by-products;
  • Adsorption process, industrial and environmental integration, and application and modeling;
  • Nanoadsorbent and nanocatalytic materials (e.g., silica, chitosan, graphene);
  • Bioaccumulation, mobilization, biodegradation, and detoxification processes in phytoextraction.

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. Processes is an international peer-reviewed open access monthly 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.

The phytotreatment technique, which has never been used to treat emerging compounds, is used in this work to measure the phytoextraction of octocrylene (OC) in three concentrations (200, 400, and 600 μg/L of OC) by Salvinia biloba Raddi. The species proved to be a phytoextractor by accumulating OC in floating leaves at concentrations of 1,500,000 μg/kg in treatment 200 and 1,050,000 in 600 μg/L of OC. Chlorophyll synthesis was affected at all OC concentrations, especially 400 μg/L, with a chlorophyll a/b ratio of less than 1. Enzymatic activity responded to the contaminant: CAT and APX are inhibited in the submerged portions after 48 h, staying below 2.0E−6 μmol/min/μg of protein. GPOX was totally inhibited during the experiment, and SOD remains active at 200 and 600 μg/L. The cytogenotoxic effects of OC to confirm phytoextraction were evaluated by globally regulated tests with Allium cepa bulbs and germinal bulbs in Lactuca sativa and Avena fatua every 48 h. These tests showed that after 72 h of phytoextraction, the medium was no longer cytogenotoxic and the seeds germinated above 30%, confirming the phytoextractor capacity of S. biloba. Thus, we can affirm that S. biloba can be used in the phytotreatment of aquatic environments contaminated with OC. Full article
