Babies May Be Drinking Millions of Microplastic Particles a Day
"In the meantime, you can take steps to reduce the number of particles that slough off a bottle and into your baby’s formula, Boland says. Temperature is a key factor. After sterilizing a bottle in boiling water, he says, rinse it at least three more times in sterilized room temperature water. To prepare the formula, do so in a nonplastic container with at least 70 degree C water. Let it cool to room temperature, then transfer it to the bottle. That keeps hot water from sloshing around inside the bottle, cutting down on the number of dislodged particles.
“I think the important learning is never, ever, ever use a microwave oven to heat anything with a plastic container,” says Boland. “Because what happens is you get in fact the local heating of the plastic and the water together, which gives enhanced levels of microplastic generation. And so that combination we think is particularly potent.”
Scientists discover that baby bottles shed up to 16 million bits of plastic per liter of fluid. What that means for infants’ health, no one can yet say.
