Advances in Ecotoxicology and Environmental Toxicology

Dear Colleagues,

The rapid expansion of anthropogenic activities has introduced a complex array of chemical stressors into the environment. Understanding the biological consequences of these contaminants is a central challenge in modern science. This Special Issue, "Advances in Ecotoxicology and Environmental Toxicology," is dedicated to exploring the intricate interactions between environmental pollutants and biological systems.

In alignment with the scope of Biology, this Special Issue shifts the focus from purely environmental concentrations to the fundamental biological processes triggered by toxicant exposure. We aim to collect high-quality research that elucidates how emerging and legacy contaminants (such as microplastics, PFAS, pesticides, PPCPs, and industrial chemicals) disrupt biological homeostasis. We are particularly interested in studies that employ modern biological techniques—including multi-omics, high-resolution imaging, and high-throughput screening—to decipher the molecular, cellular, and physiological mechanisms of toxicity.

By utilizing diverse model organisms (e.g., zebrafish, medaka, Daphnia, model microorganisms and various cell lines), we hope to provide a comprehensive view of the toxicological pathways that lead to impaired health, altered behavior, and reduced fitness.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

• Molecular and cellular mechanisms of action of environmental toxins;
• Oxidative stress, DNA damage, and epigenetic alterations in response to pollutants;
• Physiological and metabolic disruptions (e.g., gut–liver axis, endocrine disruption);
• Neurobiology and behavioral toxicology in aquatic and terrestrial models;
• Developmental and reproductive biology under chemical stress;
• Integration of systems biology and multi-omics in toxicological assessment.

We look forward to receiving your contributions to this exciting collection of biological insights into environmental challenges.

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 250 words) can be sent to the Editorial Office for assessment.

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 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 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.
