Study combines in silico, in vitro, and in vivo methods to identify food contact chemicals interfering with retinoid-X-receptor (RXR), potentially leading to adverse biological outcomes by endocrine disruption; predicts 104 RXR-interacting chemicals, dominated by 58 butylphenols; three of six tested tert-butylphenols potentiate thyroid hormone signaling at nanomolar levels; identifies structural features that enhance RXR binding

Recent studies explore the presence and migration of diverse synthetic antioxidants in Chinese food contact materials (FCMs); both phosphite antioxidants and synthetic phenolic antioxidants are commonly found; typically, FCMs contain several mg of synthetic antioxidants per kg FCM and may be the primary source of exposure to synthetic antioxidants; some commonly found antioxidants are suspected endocrine disruptors

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
