Special Issue Information

Dear Colleagues,

This Special Issue aims to collect high-quality research and review articles on the latest knowledge about the chemical characteristics of micro- and nano-plastics, as well as their chemical risks of release into the environment.

Over time, pollution has increased to the same extent as human activities. Since its emergence in the 19th century, plastic has made human life more bearable, bringing innumerable benefits to our society. However, overproduction and irresponsible management have led to plastic waste reaching the planet’s most remote habitats. A particular concern is plastic in the form of micro- and nano-particles.

This Special Issue aims to publish recent advances and state-of-the-art research articles and reviews from the core of the field of chemical research to address the growing problem and impact of this anthropogenic pollutant on the environment and human health.

Research fields at the frontiers of chemistry and molecular sciences, such as biology, biochemistry, ecotoxicology, environmental safety, chemical engineering, materials science and technology, and food chemistry, will be used to achieve this goal.

The Special Issue will focus on but is not limited to the following topics:

  • Colloidal behavior of MNPs in aqueous media.
  • Chemical characterization of MNPs in aqueous media.
  • Sorption of various compounds on MNPs (pharmaceuticals, pesticides, metals, metal-NPs, PAHs, PCBs) under different physicochemical conditions.
  • Dynamics of desorption—dependence on physicochemical conditions.
  • Chemical weathering and subsequent aging of MNPs concerning pH, temperature, and surrounding media chemical characteristics.
  • MNPs' interactions with proteins (including enzymes and hormones).
  • Degradation of MNPs in various chemical conditions (including advanced oxidation processes and photochemical degradation).
  • Biodegradation of MNPs—promising enzymatic reactions, consumption by mycelium.

This short review aims to critically discuss the recent advances in supramolecular chemistry to achieve the aggregation of nanoplastics in aquatic systems. Polymer modification provides a vital tool for designing novel and ad hoc synthesized surfactants with properties tuned for some specific applications (e.g., stimuli-responsive nanomaterial, conducting polymers), mainly to aggregate other polymers from the environment. Far from the typical use of surfactants, which ease the dispersion of insoluble molecules in water media or aid solubilization of insoluble molecules on local media, in this case, nanoarchitectonics serve researchers to design surfactants with a focus on the capture of nanoplastics from the environment. Additionally, monovalent and divalent salt additions aided NPs in coagulating in the aquatic systems. Finally, the latest research on NPs’ removal efficiency on wastewater treatment plant is reviewed to summarize the advances. Full article
