Description
Bisphenol A (BPA) is a compound that mimics estrogen. This allows BPA to bind to estrogen receptors in the body in place of estrogen. This mistaken binding results in BPA acting as an agonist and antagonist for certain mechanisms in the body. This can result in early development, reproductive issues, and cancer. This project focused on the effects of brushing on the level of BPA by adding friction and movement to the toothbrush while it was soaking in the solution. The solution was used to draw the BPA out of the toothbrushes into the solution to make the levels testable by spectrofluorimetry. The excitation and emission intensities of the samples were collected and compared to a calibration curve to determine the concentration of BPA present in each sample. Data were compared to samples that were collected without brushing to determine if the friction affected BPA leached from the toothbrushes.
