The Use Of Bpa And Its Effects On The World

Polycarbonate plastic is everywhere. Manufacturers make about 2.7 million tons of plastic containing BPA each year. It’s used in screwdriver handles, eyeglass lenses, DVDs, CDs, and food containers. Although versatile and durable, polycarbonate contains a controversial chemical called bisphenol A, or BPA. Some studies have linked BPA exposure to a variety of health problems. Bisphenol has many forms, but its most common is Bisphenol-A, also known as BPA. In this paper, I will address the history of BPA, the ecological effect of using it in polycarbonates, and an interesting solution to the issue at hand. This innovation totally changed the game when it was first introduced. But, the chemist responsible for integrating BPA into plastics had…show more content…
Polycarbonates started out in fuse boxes, plug connections and glazes for public buildings. Polycarbonates soon became popular for many other uses, such as plastic bottles and linings for metal-based food and beverage cans. The use of polycarbonates for food packaging easily received approval in the 1960s by the FDA under its food additive regulations. During the early 1990s, Dr. Feldman became the first researcher to identify the possible impact of low levels of BPA. Feldman and his team discovered an estrogenic molecule while growing yeast in plastic flasks in 1992. They discovered the yeast wasn’t synthesizing the estrogen, but rather it was leaching from the plastic. The team then performed a control experiment without the yeast in the flask, and they found there was still an estrogenic molecule present, which they later identified as BPA. Once they made the connection between polycarbonate, BPA and estrogenic activity, Feldman and his team contacted a major producer of polycarbonates. It turns out, the company had already looked into the leeching issue, but after using their own methods, they said they “couldn 't find any estrogenic activity.” Other studies soon popped up, including the University of Missouri-Columbia that found low-level exposure to BPA may harm the prostate. Over the next decade, reports on low-dose BPA toxicity will grow to include more than 100
