Cover Picture
This cover picture summary describes research showing that polystyrene foam food containers release microplastics during normal everyday use. The finding raises concern about a common and often overlooked source of microplastic ingestion by humans.

Role of Residual Monomers in the Manifestation of (Cyto)toxicity by Polystyrene Microplastic Model Particles
Researchers investigated whether the toxicity observed in laboratory studies using polystyrene microplastic particles might actually come from leftover styrene monomer trapped in the particles rather than the plastic itself. They found that standard commercial polystyrene particles containing residual monomers showed mild toxicity to mammalian cells, while thoroughly purified particles did not. The study suggests that some reported toxic effects of microplastics in lab settings may be partly attributed to chemical residues rather than the plastic particles alone.
Nanoplastics in the oceans: Theory, experimental evidence and real world
Researchers critically review over 200 studies on nanoplastic pollution — focusing predominantly on polystyrene — synthesizing knowledge on how nanoplastics form from polymer degradation, accumulate in seawater, and affect organisms in controlled conditions, while identifying key methodological standards needed for reliable ecotoxicological assessments.
Quantitative analysis of polystyrene microplastic and styrene monomer released from plastic food containers
Researchers analyzed how polystyrene food containers release microplastics and styrene monomers under everyday conditions like heating and UV exposure. They found that containers released significant amounts of both microplastic particles and chemical compounds that could enter food. The study raises concerns about human exposure to microplastics through common disposable food packaging.
