Research scope
The article provides a comprehensive review of the presence of Per- and Polyfluoroalkyl Substances (PFASs) in food packaging. This is a significant contribution to the field as it brings together scattered information about PFASs in food packaging into one place. The authors have done an excellent job of collating and presenting this information clearly and concisely.
Findings
The study identifies 68 PFASs in various food contact materials, including paper, plastic, and coated metal. This is a concerning finding, as PFASs are known to be persistent in the environment and can accumulate in the human body, leading to potential health effects. The fact that long-chain perfluoroalkyl acids continue to be found, despite global efforts to reduce the use of these substances, is particularly alarming. The findings of this study have important implications for policy and practice. They support international proposals to restrict PFASs as a group, including their use in food contact materials, to protect human and environmental health. This is a strong call to action for policymakers and industry stakeholders.
Critique
While the article provides valuable insights, there are areas where it could be improved. For example, it would be beneficial to have more information on the potential health effects of exposure to these substances. Additionally, the study could benefit from a more detailed discussion of alternative materials and strategies for reducing PFAS use in food packaging.
Conclusion
the article is a significant contribution to the literature on PFASs in food packaging. It highlights the urgent need for more research and stronger regulations to protect public health and the environment. However, more work is needed to fill the data gaps and explore alternatives to PFASs in food packaging.
