Bisphenol A in polycarbonate is not a Serious Hazard to Human Health Es

Is the Bisphenol A in polycarbonate a serious hazard to homophile health?Abstract Polycarbonate, which is a polymer plastic, is found in many bottles and nutrient packaging around the world. However, because Bisphenol A is used in theprocessing of it, there is a potential danger to humans. Bisphenol A is a molecule that is ahormone inhibitor and also mirrors the function of estrogen. Although the EPA hasreleased a safe level for Bisphenol A ingestion, recent seek has shown that thoselevels may not be safe for humans. Until further testing is done, scientists arent certainof the threshold of BPA intake in humans before dangerous health effects occur.Polycarbonate of Bisphenol A is a thermoplastic polymer that is easily shaped,worked with, and transformed. It has become a popular plastic for manufacturers to use,and they have been under fire recently for making bottles and food packaging out of thispossibly potent material. Polycarbonate has the recycling number 7 and usually the le ttersPC. It contains multiple functional groups linked together by carbonate groups in amolecular chain. In the structure of this repeating molecule, there are the carbonategroups and methyl groups. The polycarbonate of Bisphenol A (BPA) is different from theothers because it is processed using that molecule. The price reduction of this type ofpolycarbonate is as follows2Bisphenol A and sodium hydroxide react to form the sodium salt of Bisphenol A.http//pslc.ws/macrog/pc.htmThen, this molecule is reacted with phosgene. Phosgene was once used as achemical weapon in World War I, but now is an important component of organiccompounds. The molecular formula of phosgene is Cl2CO.http//pslc.ws/macrog/pc.htm Final step in... ...and point dependency of thepharmacokinetics and metabolism of bisphenol A in neonatal sprague-dawley rats following oraladministration. 77(2) 230-242.Elsby, Robert, James Maggs, John Ashby, and Kevin Park.
