Special Issue Information

Dear Colleagues,

Microplastics and plastic additives pose ecological risks to natural functions. Evidence has shown the prevalence of microplastic pollution. Toxicity studies have also confirmed the hazards of microplastics to organisms and the impact of microplastics on ecological functions.

Although already-published studies have provided valuable knowledge, there is still a need for more efforts to be exerted for the control of plastic pollution. The deficiencies within the literature include a lack of monitoring data; analytical methods; toxicity mechanisms; and the migration and transformation process. Therefore, this Special Issue focuses on microplastics and their related additives in soil, water, and sediments. Topics of interest for this Special Issue include, but are not limited to, the following:

  • Migration of microplastics/plastic additives in soil, water, and sediments.
  • Removal and treatment of microplastics in soil, water, and sediments.
  • Transformation and degradation of microplastics in soil, water, and sediments.
  • Occurrence of microplastics/plastic additives in soil, water, and sediments.
  • Pollution fluxes of microplastics in soil, water, and sediments.
  • Separation and analytical method on microplastics and relevant additives.
  • Toxic effects and mechanisms of microplastics and plastic additives.

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.

Biofilms that colonize on the surface of microplastics (MPs) in freshwaters may pose a potential health risk. This study examined factors that influence MP-associated biofilm growth, including polymer type, degree of weathering, and source water quality.

Biofilms that colonize on the surface of microplastics (MPs) in freshwaters may pose a potential health risk. This study examined factors that influence MP-associated biofilm growth, including polymer type, degree of weathering, and source water quality. Weathered MPs produced in-lab were employed in biofilm trials conducted on site using a passive flow-through system with raw water at drinking water treatment facility intakes. Adenosine triphosphate (ATP) was used to quantify biofilm abundance; biofilm composition was assessed via metagenomic sequencing. Biofilm growth was observed on all polymer types examined and most prevalent on polyvinyl chloride (PVC), where ATP levels were 6 to 12 times higher when compared to other polymers. Pathogen-containing species including Salmonella enterica and Escherichia coli were present on all polymers with relative abundance up to 13.7%. S. enterica was selectively enriched on weathered MPs in specific water matrices. These findings support the need to research the potential accumulation of pathogenic organisms on microplastic surfaces. Full article
