Determination Of Bisphenol A (Bpa) In Infant Oral Hygiene Devices Using Fluorescence Spectrophotometry, Kaitlyn Thomason

Honors Theses

Bisphenol A (BPA) is an organic, solid substance that is structurally similar to estradiol, a naturally-occurring form of the female sex hormone estrogen. Since the 1957 discovery that BPA can function as an effective hardener, BPA-based plastics have been used to make a variety of consumer goods, such as water bottles, baby bottles, DVDs, eyeglass lenses, and medical devices, while BPA-based epoxy resins have been used to coat the insides of various food and drink containers, to line the insides of water pipes, and to create the thermal ink found on paper sales receipts. In recent years, however, numerous studies …


Determination Of Bpa In Infant Oral Hygiene Products Using Fluorescence Spectrophotometry, Mallory K. Mayfield Jan 2019

Determination Of Bpa In Infant Oral Hygiene Products Using Fluorescence Spectrophotometry, Mallory K. Mayfield

Honors Theses

Bisphenol A (BPA) is commonly used to make plastics, and it is also used to make epoxy resin linings for metal food containers. People are exposed to this chemical daily through bottles, metal food containers, and other plastic products. BPA exposure has been linked to negative effects on the body including cardiovascular diseases, diabetes, and reproductive problems. Special caution should be taken for children because their systems are not fully developed, and they are often more susceptible to the negative effects. BPA can bind to estrogen receptors and activate them. It has this ability because of structural similarities to estradiol. …
