BPA or Bisphenol A is Everywhere - Are We Safe?
BPA otherwise known as Bisphenol A is a compound widely used in the manufacture of plastics and epoxy resins. This industrial chemical has created
quite a stir since 2007 and is still a subject of intense controversy. BPA can be found in plastics around us and is in the products that we use every

for most people is through the diet...BPA in food and beverages accounts for the majority of daily human exposure."However, not all plastics contain
BPA. Plastics are categorized into 7 types according to the recycling process and the classification codes are located at the bottom of plastic

that mimics the neurotoxic properties of the hormone estrogen. According to the Pediatric Environmental Health Specialty Unit (PEHSU) of the
Association of Occupational and Environmental Clinics (AOEC). "BPA has been associated with increases in developmental disorders of the brain and
nervous system in animals. These developmental disorders in animals are like problems such as ADHD (attention deficit hyper-reactivity disorder) in
humans."PEHSU reports that "BPA may cause changes in cells in breasts, the uterus, and the prostate which can increase risk of cancers." The
September 2008 report of NTP suggests that BPA exposure may be linked to prostate and brain cancer.The NTP report also says that BPA can cause
behavioral problems in fetuses, infants and children. It can induce early onset of puberty in gi
