Special Issue Information
Microplastics are synthetic polymer particles less than 5 mm in diameter that can originate from both primary (i.e., textiles, plastic production, personal care products, etc.) and secondary sources (derived from the breakdown of larger plastic debris, i.e., plastic vessels, nets, films, tires, etc.). Primary microplastics are commonly found in domestic and industrial wastewater and then can reach rivers and finally coastal areas, but the main sources of pollution in aquatic environments are usually secondary microplastics.
The physical characteristics of these pollutants (i.e., small size and large specific surface area) make them bioavailable to aquatic organisms and may therefore produce toxic effects. In very recent years, different laboratory and field experiences have confirmed that: i) aquatic organisms ingest and uptake these materials; ii) microplastics are accumulated and the chemicals they contain induce adverse effects; iii) they interact with the toxic effects of other environmental pollutants and stressors; and iv) there is trophic transfer of these pollutants and the chemicals associated with them. The existence of trophic transfer means that microplastics, once accumulated into aquatic organisms, can end up in top predators at the food chains (including humans as final consumers of many of them). These findings raise concerns regarding biomagnification of these pollutants, increasing the risks and toxic effects associated to this process. In addition, in aquatic ecosystems, microplastics have been detected also in surface waters and sediments.
For this Special Issue of IJERPH, we are looking for research articles on different aspects of microplastic pollution, including uptake quantification in organisms, water and sediment levels, toxicity assessment, etc. We welcome research papers as well as reviews and meta-analysis.

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. 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.
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.
