Special Issue Information

Dear Colleagues,

The phenomenal amount of plastic pollution in aquatic ecosystems worldwide is a globally recognized environmental problem. Plastic debris entering the aquatic environment are colonized by microorganisms known as the “Plastisphere” community, promoting new interface and interactions between plastics and various environmental pollutants. These plastic debris can be potent vectors for harmful pollutants and biota and present joint toxicity when ingested by aquatic species. Their further transfer along the food web can accelerate the wide array of impacts. Ecotoxicology of aquatic plastic debris is an important area to be studied, linking anthropogenic input to environmental consequences for aquatic ecosystems, which is of great ecological and economic significance.

In this Special Issue, we encourage the submission of papers related to the ecotoxicology of aquatic plastic debris, including but not limited to microbial colonization and formation of plastisphere, microbial degradation and surface interactions, vector properties and effects, ingestion and depuration of plastic debris, source tracking and monitoring, and so on. Both research articles and reviews are 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. Journal of Marine Science and Engineering 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 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.

Microplastic pollution of the aquatic environment is one of the most serious environmental problems today. The potential environmental risks of such particles have become growing concerns in recent years, as direct or indirect exposure to these particles leads to adverse effects on marine organisms. In this study, we investigated the potential risk of polystyrene (PS) microspheres on the genome integrity of cells of different tissues (gills and digestive gland) of the filter-feeder mollusk Mytilus trossulus, using a comet assay. With the help of the comet assay, we estimated the level of genome destruction in the cells of two different mussel tissues after short-term exposure to polystyrene. It was discovered that, despite their chemical inertness, PS microspheres that are 0.9 µm in diameter, at a concentration of 106 particles/L, exhibit genotoxic properties, which are expressed as a two-fold increase in the level of cell DNA damage of the mussel’s digestive gland. It is noted that, after exposure to PS, about half of the mussel’s digestive gland cells experienced damage in 25–35% of their DNA. In addition, the proportion of cells with significant DNA damage (50%) was about 5%. Given the unique role of the genome, DNA damage in these cells may be the earliest stage in the development of biochemical events that lead to toxic effects. These findings provide a basis for studying specific biomarkers of microplastic contamination. Full article
