| Abstract | ||
| The chemical Bisphenol A (BPA) was first synthesized in 1891; in 1930 a study found that BPA mimics estrogen. Today bisphenol A (BPA) is manufactured in excess of six billion pounds per year. BPA is most commonly used as the building block of polycarbonate plastic for products such as baby bottles and water bottles, epoxy resins (coatings that line food containers), and white dental sealants. It is also an additive in other types of plastic used to make children’s toys. BPA molecules are bound by "ester bonds” to form a polymer used to make polycarbonate plastic. As the building block of polycarbonate, BPA is the primary chemical in polycarbonate, and it does not exist in only trace amounts. While plastics are typically thought of as stable, scientists have known for many years that the chemical bond between BPA molecules is unstable. The bond is disrupted by heat and acidic or basic conditions that release BPA into food or beverages in contact with the plastics. Now, there have been over one hundred studies that link BPA that can cause cancer and other health conditions in exposed people. Pregnant woman who absorb a common chemical from everyday plastic products such as water bottles and other containers could be putting their unborn children at a risk of developing cancer and other diseases when they reach adulthood. Animal studies found that exposure in the womb to Bisphenol A caused changes associated with obesity, cancer and diabetes. This chemical is banned in Canada, some states in U.S, other European countries, in the last two decades, more and more breast cancer in Korea has been related to BPA. Now, breast cancer is ranked the leading cause of cancer in Korean woman. | ||
