How Are Children and Adults Exposed to BPA?

Because BPA is used in the manufacture of a variety of high-volume consumer products, there are a number of possible routes of exposure for members of the general population. These can be divided into (1) direct and indirect environmental exposure due to the release of BPA during its production, use, and disposal; (2) exposure through leaching into food; and (3) contact with or inhalation of non-food-contact consumer products. Environmental measurements and knowledge of the properties of BPA suggest that environmental sources of BPA exposure do not contribute significantly to overall population exposure.[1]

It also does not appear that nonfood consumer products are significant sources of BPA exposure in the general public. Thus, the main concern is about exposure through food, particularly for infants who may be exposed through migration of BPA into milk from polycarbonate bottles and from migration of BPA into formula and canned infant foods from epoxy resin coatings of formula and food containers. The particular concern about infants is based on the assumptions that infants are most susceptible to any adverse effects of BPA and that infants ingest larger amounts of BPA per body weight than older children and adults.
