Inventory list for printed paper and board FCMs
Scientists compile inventory list of chemicals used in printed paper and board FCMs; 1,769 single substances are non-evaluated for their toxicity; of these, 19 substances with actual use confirmed by FACET are included in ECHA’s lists for substances of concern
Aggregate exposure assessment for BPA
Scientists discuss aggregate exposure assessment for bisphenol A; source-to-dose (forward) and biomonitoring-based (backward) calculation resulted in similar estimates; 90% of exposure comes from diet and the remaining 10% mainly from dermal exposure
