Special Issue Information

Dear Colleagues,

Plastic pollution has reached even the most remote places on Earth, entailing challenges spanning human health, social justice and environmental impacts. The ecotoxicological effects of plastics have been described for a multitude of species; however, important knowledge gaps persist, for example in differentiating the intrinsic toxicological effects of plastics from those induced by plastic additives.

In this context, we are pleased to invite you to submit contributions to this Special Issue on the ecotoxicological effects of plastics on organisms.

This Special Issue aims to improve understanding of how exposure to plastic alters the physiological, immunological and behavioral responses of organisms. A particular focus will be placed on laboratory exposure studies using environmentally relevant plastic concentrations.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: bioassays, behavioral changes, leachate toxicity studies and ecosystem approaches. Transdisciplinary approaches are highly encouraged.

I look forward to receiving your contributions.

Dr. Natascha Schmidt

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. Biology 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 2700 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.

Microplastics and nanoplastics are abundant in the environment. Further research is necessary to examine the consequences of microplastic contamination on living species, given its widespread presence. In our research, we determined the toxic effects of PET microplastics on Drosophila melanogaster at the cellular and genetic levels. Our study revealed severe cytotoxicity in the midgut of larvae and the induction of oxidative stress after 24 and 48 h of treatment, as indicated by the total protein, Cu-Zn SOD, CAT, and MDA contents. For the first time, cell damage in the reproductive parts of the ovaries of female flies, as well as in the accessory glands and testes of male flies, has been observed. Furthermore, a decline in reproductive health was noted, resulting in decreased fertility among the flies. By analyzing stress-related genes such as hsp83, hsp70, hsp60, and hsp26, we detected elevated expression of hsp83 and hsp70. Our study identified hsp83 as a specific biomarker for detecting early redox changes in cells caused by PET microplastics in all the treated groups, helping to elucidate the primary defense mechanism against PET microplastic toxicity. This study offers foundational insights into the emerging environmental threats posed by microplastics, revealing discernible alterations at the genetic level. Full article
