Special Issue Information

Dear Colleagues,

You are invited to submit to the upcoming Special Issue “Risk Assessment of Pollutants in Aquatic Environments”.

Many chemicals are used in, and directly or indirectly released from, processes and products that are essential for human health, nutrition, and wellbeing. These include substances such as pharmaceuticals, personal care products, radionuclides, macronutrients such as phosphorus and nitrogen, trace elements, particulates, and other organic and inorganic compounds. However, these chemicals and their breakdown products have hazardous properties that can pose a risk to the aquatic environment, ecosystem services, and human health. Risk assessments, based on fundamental knowledge of transport, fate, exposure and effects, are essential for safe chemical use and release.

This upcoming Special Issue of Water aims to collect insightful reviews and research articles on integrated long-term monitoring, residue analysis, laboratory and field experimentation, and multiscale modelling of chemicals in the environment. Focussing on priority and newly emerging pollutants, studies on the development of new approaches and tools for hazard screening, risk assessment, and source apportionment for emergent technologies are particularly welcome. So are those on the exploration of how chemical risks vary with likely future climate and demographic change, increasing urbanisation and a move towards low carbon economies. It is hoped that the new knowledge generated from this Special Issue translates through to policies and mitigation strategies that deliver safe management of chemicals, now and in the future.

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.

Of all the antibiotics used today for human treatment in the world, macrolide antibiotics—erythromycin, clarithromycin and azithromycin—stand out the most for misuse, and they were included as high-risk substances in the monitoring Watch List of Regulation 2018/840/EU. The aim of the present research was to investigate the level of target human pharmaceuticals’ prevalence in the environment by the substance flow analysis (SFA) approach and to determine the potential risks of the antibiotics for the environment. The target for the environmental investigations was Lithuania. For SFA, 2021 consumption input data were used, and such key processes as the consumption rate, disposal and distribution of pharmaceuticals in the environment were analyzed. The analysis revealed that the largest part of pharmaceutical contaminants (80.1%) enters wastewater treatment plants. The risk quotient approach was based on the determination of predicted environmental concentrations (PECs), measured environmental concentrations (MECs) and their ratio to the predicted no-effect environmental concentrations (PNECs). The analysis revealed that clarithromycin causes a high potential risk for the aquatic environment in effluents from the wastewater treatment plants (WWTP); PEC/PNEC > 7. For azithromycin and erythromycin, the estimated PEC values were between 0.1 and 1. Clarithromycin concentration in the effluents of two target WWTPs showed a significant risk quotient (MEC/PNEC) of higher than 7. Recommendations on how to reduce the release of pharmaceutical residues into the environment have been proposed in the framework of the environmental management system. Full article
