Special Issue Information

Dear Colleagues,

In our fast-paced world, the use of synthetic chemicals is on the rise for producing a wide range of products including agricultural, medicinal, personal care, and household products. Consequently, we have become accustomed to encountering these synthetic chemical-based products in our daily lives because of their availability and affordability. These chemicals typically end up in environmental water sources through industrial and/or municipal wastewater effluent discharges. Among the wide range of aqueous contaminants, persistent organic pollutants (POPs), and emerging contaminants pose serious challenges to global water quality. Conventional wastewater treatment plants were not designed to remove emerging contaminants. Subsequently, they end up in environmental waterways. POPs and emerging contaminants in water can seriously affect the health of both human and aquatic organisms. Examples of POPs and emerging contaminants include pesticides, antibiotics, pharmaceuticals, per- and poly-fluoroalkyl substances (PFAS), polybrominated biphenyls, polybrominated diphenyl ethers, and dioxins.

Research is being carried out for the removal of these contaminants using advanced treatment methods such as membrane filtration, modified adsorbents, advanced oxidation processes, membrane bioreactor, and unconventional biological (e.g., algal and enzymatic) treatment methods. For this Special Issue of the International Journal of Environmental Research and Public Health, manuscripts (research, reviews, short communications) are solicited that report the current contamination of POPs and emerging contaminants in water/wastewater, and bench- and pilot-scale studies indicating the effectiveness of emerging treatment technologies for removing these contaminants.

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. International Journal of Environmental Research and Public Health 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 2500 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.

In the present research, the effect of two hybrid treatments, ozone followed by powdered activated carbon (PAC) or PAC followed by ozone (O3), was studied for the removal of two drugs present in water: diclofenac and carbamazepine. In the study, two initial concentrations of each of the contaminants, 0.7 mg L−1 and 1.8 mg L−1, were used. Different doses of PAC between 4–20 mg L−1 were studied as variables, as well as different doses of O3 between 0.056–0.280 mg L−1. The evolution of the concentration of each contaminant over time was evaluated. From the results obtained, it was concluded that the combined treatment with ozone followed by PAC reduces between 50% and 75% the time required to achieve 90% removal of diclofenac when compared with the time required when only activated carbon was used. In the case of carbamazepine, the time required was 97% less. For carbamazepine, to achieve reduction percentages of up to 90%, O3 treatment followed by PAC acted faster than PAC followed by O3. In the case of diclofenac, PAC treatment followed by O3 was faster to reach concentrations of up to 90%. However, to reach yields below 80%, O3 treatment followed by PAC was more efficient.
