Detection and Adsorption of Cyanotoxins in Waters

Dear Colleagues,

This Special Issue presents recent advances in the detection and adsorption of cyanotoxins and other co-occurring contaminants within aquatic systems, addressing escalating risks associated with harmful algal blooms in drinking, recycled, and recreational waters. Contributions highlight cutting-edge analytical approaches, including high-resolution mass spectrometry; biosensing platforms; and molecular tools capable of rapid, sensitive, and selective detection of diverse cyanotoxins in complex matrices. Several studies explore machine learning-assisted interpretation to enhance early warning capability. In parallel, the Special Issue showcases innovative adsorption strategies using functionalized nanomaterials, bio-adsorbents, and engineered porous media for effective removal of microcystins, cylindrospermopsin, and related toxins. Mechanistic evaluations of adsorption kinetics, surface interactions, and field-scale validation demonstrate practical applicability. Importantly, emerging nature-based solutions—such as constructed wetlands, biofiltration systems, and eco-engineered material and substrates—are examined as sustainable pre-treatment barriers and as treatment options for recreational waters. Collectively, these contributions advance integrated monitoring and treatment frameworks to protect public health and strengthen resilient water management strategies.

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 double-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Toxins 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.
