Dear Colleagues,

The good chemical and ecological status of water bodies is crucial for ensuring the sustainability of social-economic development. However, during recent decades, aquatic basins all over the world have been under increased human pressure, which in turn could contribute to significant decline in aquatic faunal populations and biodiversity, as well as the degradation of habitats and natural resources, thus threatening environmental and human health at higher time scales. To assess the pollution risk and the negative impact of single (metals, pesticides, pharmaceuticals,! biocides, nanomaterials, and polymers such as micro- and mesoplastics, etc.) or mixed contaminants (municipal and/or industrial wastes, agrochemicals, landfill leachates, atmospheric inputs, etc.) on aquatic media, (eco)toxicological methods are increasingly applied for determining potential adverse effects (including acute and chronic effects, cellular, biochemical and molecular alterations, etc.) on aquatic organisms of different trophic levels.

Aiming to bring together researchers all over the world that can enrich the current state of knowledge on the Toxicity of Contaminants on Aquatic Organisms II, we are pleased to invite you to contribute to the release of the current Special Issue of Toxics. In this Special Issue, commentaries, original research articles, reviews, and short communications (without restriction on their length), are welcome. Research areas may include (but are not limited to) both laboratorial (in vitro and/or in vivo) and field studies regarding the chemical-related toxic effects (acute or chronic toxicity, cytotoxic, genotoxic, oxidative-stress-related effects, etc.) of either single (metals, pesticides, pharmaceuticals, biocides, nanomaterials, and polymers such as micro- and mesoplastics, etc.) or mixed contaminants (whole effluent toxicity testing methods in municipal and/or industrial wastes, agrochemicals, landfill leachates, atmospheric inputs, etc.) on freshwater or saltwater (marine) species or biological models (cells, tissues, organs, etc.), as well as studies relating to new methods for assessing the toxicity of contaminants to aquatic organisms.

We look forward to receiving your contributions.

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. Toxics 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.
