Abstract

Microbeads, primarily made up of polypropylene that are smaller than 1mm, are most commonly found in face washes and toothpastes. These microbeads, when poured down the drain, end up polluting many marine habitats causing contamination. The effect that these micro plastics have on the habitats on marine species was studied using Daphnia magna. The purpose of this experiment is to determine the effect that microbeads found in Neutrogena Deep Clean Gentle Scrub have on the mortality percentage of Daphnia magna. This was tested by isolating the microbeads from the product, adding different specified masses to each experimental group that contain ten Daphnia magna each. Then the percent of mortality and the percent of survival was measured after 24 hours and 48 hours. This experiment is still on going and result are still being collected.
