US EPA reissues PFBS risk assessment
US Environmental Protection Agency (US EPA) reissues risk assessment on perfluorobutane sulfonic acid (PFBS); sets reference doses for chronic exposure of 0.0003 mg/kg body weight/day and sub-chronic exposures of 0.001 mg/kg body weight/day
Studies present new generic and specific modeling approaches for FCCs migration
Scientists develop nonlinear model for predicting food contact chemical (FCC) migration and apply it to FCCs of high toxicological concern; emphasize usefulness of their model to speed up migration assessment of FCCs; different group of scientists proposes an innovative modeling approach to assess release of a specific additives and elements from plastic food packaging and steel processing tools

The chemical and waste footprint of food delivery in China
Study uses online food delivery sales data from nearly 200 Chinese cities, combined with packaging samples from 18 of those cities to model packaging waste generation and chemical exposure from waste incineration; some degradation products with higher concentrations than intentionally added parent product; over 50 tons of the targeted additives likely released into the atmosphere from Chinese waste incinerators
Formaldehyde and melamine migration from tableware
Italian scientists investigate migration of formaldehyde and melamine from children’s tableware made of melaware and other amino resins; specific and overall migration limits exceeded in some products; aging increases migration; migration cannot be predicted from product’s appearance
