Bisphenol A (BPA)
Bisphenol A is a harmful chemical found in most everything made of plastic. It is in obvious things, such as paint, and it is in not so obvious things such as baby bottles. Small amounts of BPA are harmless to humans, but extreme amounts of BPA can have life threatening affects. BPA is used to make Polycarbonate Plastics. The Plastics produced are the lightest weight and the toughest of all plastics. Approximately 2.8 million tons of BPA is produced yearly in the world. Studies have also shown that BPA exists in dental sealants and puts the user at risk of exposure. BPA is the world’s most tested chemical in the world, but it also has the most unanswered question
BPA has shown the ability to cause medical problems in animal testing. Medicine Net says that “Studies done on laboratory rodents have shown that high doses of BPA during pregnancy and lactation can reduce survival, birth weight, and growth of offspring early in life, and delay the onset of puberty(Medicine Net NPA).” These serious problems are possible in humans as well; however, the amount of BPA necessary to ingest is much more than a human is exposed to in a life time. Infants are exposed to much more BPA than the rest of the human population. “BPA is found in the plastic baby bottles and the linings of cans of powdered and liquid formula (Medicine Net NPA).” Babies are also exposed to BPA in their pacifiers. With all the BPA exposure in an infant’s small body, serious side effects could occur. Originally it was thought that BPA has no effect on aquatic life. However, after extensive research, it was proven that BPA has a similar affect on aquatic life as on humans. BPA leaks out of factories and into our oceans and water ways. This causes a very highly concentrated content of BPA. BPA also gets into the water from water bottles. Although plastic does not decompose easily, in saltwater plastic decomposes rather rapidly, releasing their content of BPA into the water. The BPA...
