Children with autism and ADHD may have a harder time getting rid of harmful plastic chemicals from their bodies, according to a new study. Researchers found these kids clear bisphenol A (BPA), a common chemical in plastics, more slowly than other children. That means BPA stays in their bodies longer, potentially raising risks to their developing brains.

The study looked at how kids break down BPA, which is found in things like food cans, plastic containers and receipts. Kids with autism had about 11% lower detox levels, while those with ADHD were 17% lower than average. BPA is  known to disrupt hormones, and early exposure has been linked to changes in the brain.

While this study doesn’t prove BPA causes autism or ADHD, it suggests these children may be more sensitive to its effects. Experts recommend practical steps to reduce exposure, such as using glass or metal containers, choosing fresh foods over canned goods, and avoiding printed receipts. Researchers say more studies are needed to understand exactly how BPA and brain development are connected.
