Toxic napkins

CHEM Trust revisits issue of paper napkin contamination by primary aromatic amines used in ink production, calls for improved regulation of chemicals in food contact paper and inks

Migration of nitrosamines from FCMs

Scientists develop analytical method to measure N-nitrosamines migrating from elastomeric food contact materials; 6 nitrosamines detected frequently; BfR-recommended limit exceeded for one styrene block copolymer sample

Genotoxic chemicals in coatings

Scientists compile inventory of compounds potentially used in coatings; 1,976 substances have no (recent) toxicological evaluation; subset analyzed by in silico tools and literature search, 10 compounds designated as ‘high concern’

In vitro testing of paper and board FCMs

Scientists test paper and board FCMs in 8 in vitro bioassays; all 20 samples showed positive responses in at least one of the assays; chemicals in paper and board FCMs require further investigation to ensure safety
