Abstract

Endocrine disruptors are found within several products which are prominent in everyday society, such as hard plastics, cosmetics, and personal care items such as toothpastes. The purpose of this research is to demonstrate how the endocrine disruptor containing products, BPA, Microbeads, and Colgate Total® affect the total regenerated lengths of Dugesia Tigrina, which could relate to the healing of damaged tissues within humans while being exposed to various products containing endocrine disruptors. It was hypothesised that the powdered form of BPA would hinder the Planarian Flatworms’ total time of complete regeneration the most and that the endocrine disruptor within the Colgate Total® Toothpaste would have the least effect. A ppm solution was made for each endocrine disruptor containing product and were filled halfway into the assigned petri dishes, three dishes per group with a total of four groups, making twelve dishes total. Each planaria was cut halfway and the lengths were recorded after two weeks. The regenerated lengths were calculated and it was shown that there was a significant difference between means at F(3,77) = 3.74, p < 0.05 A Post-hoc Tukey test determined that there were significant differences between the control and the BPA and the control and the Colgate Total®, which showed that both hypotheses were not supported. This meant that the BPA group did not have significantly the most hindering and that the Colgate Total® did not have significantly the least hindering overall.
