  • The interactions between microplastics and freshwater snow can influence the way in which both particle types settle in freshwater environments. Advanced and automated tracking techniques show that agglomerates of the two particles settle faster than the individual components alone, underscoring the potential repercussions on biogeochemical cycles.

  • Anthropogenic contaminants enter sea ice, with varied behavior depending on size (dissolved, colloidal, particulate) and particle density—providing insights into poorly understood incorporation mechanisms.

  • Only about 1% of microplastics added to the surface in a two-year field incubation experiment reached depths of more than 8 cm, suggesting that microplastics can accumulate in the upper layers of the soil, creating localized pollution hotspots.

  • Analytical challenges in detecting nanoplastics have hindered the understanding of their behaviour in environmental systems, but these difficulties can be circumvented by synthesizing metal-doped nanoplastics (where the metal can be measured as a proxy for the plastic) to undertake mechanistic investigations of particle fate, transport and biological interactions in lab and pilot-scale studies.

  • The positive benefits afforded by the widespread use of plastics need to be reconciled with negative impacts on the environment and health across the entire plastics life cycle. Optimizing the balance in several facets of plastics production, use and waste management is necessary for a more sustainable relationship with these materials in the Anthropocene.

  • Airborne microplastics (MPs) are observed over the Southern Ocean and Antarctica. MPs morphology is the primary factor influencing the hemispheric transport to these remote areas that may suffer increased pollution from urbanized, land-based sources.

  • This Perspective aims to place nanoplastics in the context of global plastic pollution by assessing its sources and risks, and by assessing commonalities nanoplastics may share with other nanosized objects in environmental systems.

  • Plastic pollution is recognized as a global threat, but policy hurdles and a lack of effective plastic substitutes contribute to the problem. In this Perspective, the authors argue that an effective and sustainable path forward must rely on key restrictions and regulations optimized for impact and efficacy.

  • Environmental cycling of microplastics and nanoplastics is complex; fully understanding these pollutants is hindered by inconsistent methodologies and experimentation within a narrow scope. Consistent methods are needed to advance plastic research and policy within the context of global environmental change.

  • Plastics need to be used more sustainably in agricultural practice, for example by recovery and reuse, and by selected application of safe biodegradable plastics and phasing out of toxic additives, suggests a literature synthesis and perspective on structural polymers in agriculture.
