Plastics contain various chemical substances, which can impact human and ecosystem health and the transition to a circular economy. Meanwhile, information on the presence of individual substances in plastics is generally not made publicly available, but relies on extensive analytical efforts. Here, we review measurement studies of chemicals in plastics and compile them into a new LitChemPlast database.

A suite of analytical techniques was used to obtain a comprehensive picture of per- and polyfluoroalkyl substances (PFAS) in selected Canadian food packaging used for fast foods ( = 42). Particle-induced gamma ray emission spectroscopy revealed that 55% of the samples contained <3580, 19% contained 3580-10 800, and 26% > 10 800 μg F/m. The highest total F (1 010 000-1 300 000 μg F/m) was measured in molded "compostable" bowls.

Numerous per- and polyfluoroalkyl substances (PFASs) occur in consumer food packaging due to intentional and unintentional addition, despite increasing concern about their health and environmental hazards. We present a substance flow analysis framework to assess the flows of PFASs contained in plant fiber-based and plastic food packaging to the waste stream and environment. Each year between 2018 and 2020, an estimated 9000 (range 1100-25 000) and 940 (range 120-2600) tonnes per year of polymeric PFASs were used in 2% of food packaging in the U.

Article Synopsis
  • A study analyzed 72 children's textile products, particularly school uniforms, from US and Canadian stores to determine their exposure to per- and polyfluoroalkyl substances (PFAS), known for their stain-resistant properties.
  • All products contained PFAS, with the highest concentration found in school uniforms compared to other items like bibs and swimsuits, especially those made of 100% cotton.
  • The estimated average potential exposure for children through skin contact with these uniforms was 1.03 ng/kg bw/day, and it's estimated that around 3 tonnes of PFAS are used annually in US children's uniforms.
