Abstract

Personal care products are major pollutants in freshwater environments that are often difficult to mediate due to their fluid-like properties. Hand and bar soaps often cause the most pollution in freshwater environments due to their pH level, which often jeopardizes the livelihood of surrounding wildlife. With the prospect of algaes such as Spirulina major and Oscillatoria as potential viable sources of bioremediation, the toxic pH level and effect of hand and bar soaps can possibly be reduced. The purpose of the research is to test the effectiveness ofSpirulina major and Oscillatoria in reducing the pH level of personal care products (PPCPs) in freshwater environments. The hypothesis is that the algaes Spirulina and Oscillatoria will reduce the pH level of a Dial Gold Antibacterial Bar Soap and Clorox Antibacterial Liquid Hand Soap mixture by 2 pH levels given that algae has been effective in reducing the pH level of personal care products in marine environments. The method of the research included four groups, two of which belonged to Spirulina and Oscillatoria, and the other two as control groups. Both algaes were separated into 20 mg samples, and the pH level of all samples were recorded every day for ten days and averaged for each day. The research finds that both the Spirulina major and Oscillatoria groups became more acidic through an 19.9% and 48.83% increase in pH, respectively. The results of the research suggest that the algaes did not aid in reducing the pH level of the PPCPs.
