The debate regarding the use of Bisphenol A has plagued consumer markets regarding the disputed safety of this chemical. Bisphenol A, commonly known as BPA, is the main constituent of polycarbonate plastics. Polycarbonate materials are used everywhere from CDs to food storage containers. In addition to its use in polycarbonate plastics, BPA is also found in epoxy resins which are used to make products such as paints, protective coatings, and metal food can linings. According to Chemical Market Associates Inc (CMAI), close to 2.8 million tons of BPA were produced in the year of 2002. Thomas Zincke is credited with the initial synthesis of BPA in 1905, when he combined phenol and acetone to create this useful compound. The synthesis of the chemical into plastic materials came in the year of 1953 by Dr. Hermann Schnell and Dr. Dan Fox.
With so much plastic floating around in the ocean, it’s easy to see the big stuff - plastic bottles, fishing nets, chunks of foam, and other everyday objects that we still can’t seem to dispose of properly. But what about the plastic in the ocean that we can’t see? Microplastics, or small plastic pellets, powders, fibers, and even fragments of larger plastic waste between five microns and one millimeter are also very common in the ocean and extremely damaging to this fragile environment.
