NTNU study maps the chemical load in plastics and calls for stronger controls
Researchers at the Norwegian University of Science and Technology (NTNU) conducted an in depth analysis of plastic composition. The team identified that polymer products contain more than 16 thousand chemical components, with roughly a quarter potentially posing risks to human health and the environment. The findings were documented in the PlastChem research project report.
According to the study, at least 4,200 plastic chemicals, about 26 percent, could threaten health and/or ecosystems. The assessment notes that hundreds of substances of interest were detected across diverse plastic categories, including materials used for food packaging. The scientists stress that any plastic product has the potential to release hazardous chemicals into its surroundings.
The researchers advocate for tighter regulation of substances used in plastics, greater transparency about the chemicals involved in plastic production, and simplification of polymer formulations to reduce the number of distinct ingredients. These steps are seen as essential to minimize risk and improve safety across consumer, industrial, and environmental contexts.
As stated by NTNU Professor Martin Wagner, one of the report’s authors, a comprehensive solution to the plastic challenge requires acknowledging the chemicals present in plastics and handling them responsibly and openly.
Earlier work in this field demonstrated a method to remove toxic nanoplastic from water using filtration materials derived from waste resources. This prior research underscores the potential for practical interventions to reduce micro and nano plastic pollution in water systems while broader regulatory and transparency measures take effect.
These findings contribute to the growing conversation about how societies can manage plastic production and use in ways that protect health and the environment, emphasizing the importance of informed policy, responsible manufacturing, and continued scientific scrutiny.
