It's everywhere — in our air, on our countertops, and in our kids' toys. But researchers have found that kids get the most BPA from the foods they eat.
In a previous study published in 2007, researchers collected samples of solid and liquid foods, air, dust and soil from the homes and daycare centers of 257 children between the ages of 2 and 5 in North Carolina and Ohio. At the time, researchers were able to show that the foods eaten by the children contained more BPA than any of the other sources. At the time, researchers were not able to determine if the BPA in the children's urine was the BPA that came from those foods.
Now they can.
In a new study published in the journal Environmental Science and Technology, researchers used statistical analysis to show that the BPA that the children were excreting via BPA correlated with the doses they were ingesting through their food. The study's authors were able to determine that food accounted for more than 95 percent of the BPA excreted in the preschoolers’ bodies.
