Special Issue Information

Dear Colleagues,

Environmental contaminants are mostly the result of human activities and often reach aquatic environments either deliberately or through run-off, posing serious risks to aquatic organisms.

Pollutant leaching occurs when xenobiotics mix with water and move through the soil, contaminating groundwater. Different organisms, such as plants, animals, and even humans, can be used as bioindicators of environmental pollution, primarily due to their ability to absorb toxicants from air, water, sediment, soil, and/or through the food chain. Bioindicators give us “early warning signals” about the possible effects of pollutants on populations or communes and provide the possibility of a timely reaction in order to prevent major consequences for the environment.

The application of aquatic organisms as bioindicators has a number of advantages compared to standard chemical methods for the analysis of toxic metals in environmental samples (water, air, sediment, soil).

The purpose of this Special Issue is to publish original research as well as review articles, about recent studies of aquatic organisms that have been used worldwide as bioindicators of environmental contaminants in water and sediment. We, therefore, invite you to submit your latest research findings and engineering practice in this field. Case studies are also welcome.

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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Coastal areas are frequently impacted by anthropogenic pollution, due to intense human activity in these zones. Our study aimed to monitor the impacts of anthropogenic pollution in four Portuguese locations on the northwest coast, and to identify the most affected areas and/or seasons by applying a multi-biomarker approach. Water and specimens of Phorcus lineatus were collected on the rocky shore during low tide in four sites along the northwest Portuguese coast (1. Amorosa; 2. Cabo do Mundo; 3. Homem do Leme; 4. S. Félix da Marinha) with different anthropogenic pressures, including an industrial maritime shipyard; an oil refinery; an international airport; and an area with high human population density. The collection took place over two seasons: the summer of 2021 and the winter of 2022. Several biochemical biomarkers, including reactive oxygen species; protein carbonyl content; lipid peroxidation (LPO); carboxylesterase (CE); and antioxidant (superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST), and neurotoxicity—acetylcholinesterase (AChE)) enzymes were measured. The results showed seasonal variation, with the ROS, LPO, CE, and GST activities depending particularly on the season, but the SOD and CAT activities being similar between summer and winter. CAT showed lower activity in Site 1 than in the other sites during both seasons (p < 0.05). The Integrated Biomarker Response (IBR) index showed that biomarker responses were higher in winter. The multivariate analysis confirmed the higher contribution of the factor season to the P. lineatus’ response to pollutants, compared to the spatial variation in the northwest Portuguese coast. Overall, this study shows that P. lineatus can be a suitable bioindicator species for environmental biomonitoring, and that the IBR index allows the identification of temporal contamination patterns.

Herbicides with glyphosate (GLY) as an active ingredient (a.i.) are increasingly used, and GLY is currently the most used herbicide in the world. Consequently, its residues have often been found in aquatic ecosystems. Investigating how this substance affects aquatic species is a priority in ecotoxicology research, especially in fish, as they can absorb and concentrate toxins. In this sense, a critical review was performed, synthesizing data from the peer-reviewed bibliography, reporting on the toxicity of exposure to pure GLY and glyphosate-based herbicides (GBHs), using zebrafish as an animal model. The concentrations of this herbicide that induced toxic effects are highly variable, with some exceeding the limits determined by regulatory agencies. Globally, relevant toxic effects have been reported in zebrafish, namely, teratogenic effects incompatible with life, which translates directly into an increase in reported zebrafish mortality. Neurotoxicity, genotoxicity, changes in energy metabolism and oxidative stress, and immune and hormonal system dysfunction with an impact on fish reproduction were also described. In conclusion, both GLY and GBHs may induce damage to zebrafish, compromising their survival, reproduction, and maintenance. These results may be valid and applied to other fish species and aquatic ecosystems. Full article
