A few years later, scientists figured ways to use BPA in making plastic
containers and resins that now line most food and soft drink cans.
But…uh oh…BPA polymer decays over time, so traces of the synthetic estrogen are released into canned foods and baby formula in plastic bottles. (BPA is also used to make pacifiers, plastic forks and spoons, plastic bowls, etc.)
By the time researchers started studying the effects of BPA on animals, use of the chemical was in full swing.
