It seems to me a good and ambitious review study, which provides a very interesting and complete tool for risk assessment of chemicals in food packaging.
I consider it to be well designed, with a contingency plan for possible deficiencies in data collection, using different sources to achieve the desired objective. It has a very interesting iconography that helps to understand a large volume of results.
It confirms the presence of hazardous substances in food packaging included in human biomonitoring programs, but warns of other substances not included in such programs that are widely used in such packaging and whose toxicological implication is not well known (antioxidants, oligomers).
This tool can be used by other scientists for the design of studies to respond to gaps in the studies of certain compounds and their toxicity.
It can also be used for new regulations, as well as for the development of safer alternatives to protect the consumer.
[Regarding possible limitations] The sources used are heterogeneous and with different levels of confidence, which should be taken into account before being used in future evaluations.
