A review of migration from food-contact materials. Parenthetical unit conversions in the review mix water concentrations with food mass fractions.
Key numbers
Most studies the review discusses are described as below a WHO figure written as 20 ppb and also as 0.02 mg/kg, and below an EU specific migration limit written as 40 ppb and also as 0.04 mg/kg (PDF p.2). Ordinary storage is described as often under 2.5 µg/L, and acid, heat, and time as able to exceed 5 µg/L. The review states that EPA recommends less than 0.35 µg Sb/kg body weight per day. The IRIS file was not opened, so that sentence stays a citation.
Methods (brief)
Narrative review. Not a new migration experiment.
Evidence fitness
Supports what the review prints, including the unit conflation. Does not support adopting 20 ppb as 0.02 mg/kg, or adopting 0.35 µg/kg/day as an opened reference dose.
Limitations
Not a baby-bottle study.
