Microwavable plastic food containers are used extensively in homes and as take-out containers. A Chinese study has identified 42 intentionally added substances and more than 100 non-intentionally added substances migrating from plastic food containers made of PP, SAN or Tritan.
If you consume take-out food daily it may result in an annual intake of up to 55.15 mg of chemical substances and 150 million microplastic particles from the plastic containers, including non-intentionally added substances that may be harmful.
Toxic substances and microplastics identified
According to the authors, some of the non-intentionally added substances are very toxic compounds that exceeded the recommended limits in the EU. In addition, microplastics were detected with high values of more than one million particles/L food simulant from some of the microwave containers.
The study Migration of (non-) intentionally added substances and microplastics from microwavable plastic food containers is available online at ScienceDirect and will be published in Journal of Hazardous Materials, Volume 417, September 2021.
