Leaching of bisphenol-A from polycarbonate bottles or containers into the contents has been documented.
Also banned are several plasticizers called phthalates added to PVC (#3, polyvinyl chloride) plastic products to make them soft and squishy. Many children’s toys and teethers contain phthalates that can migrate out since they’re not chemically bonded to the plastic polymer. Phthalates interfere with testosterone during fetal life, and exposure has been linked to abnormal reproductive organ development, infertility, premature breast development, shortened pregnancy, and asthma.
