Around 100 of these chemicals are considered to be of "high concern" to human health, said lead study author Birgit Geueke from the Food Packaging Forum Foundation, a Zurich-based NGO.
Some of these chemicals are relatively well-studied and have already been found in human bodies, such as PFAS and bisphenol A—both of which are the target of bans.
But little is known about the health effects of others, Geueke told AFP, calling for more research into how chemicals used in packaging end up being swallowed along with food.
