Effects of Pharmaceutical Waste on Daphnia Magna

AJAS · 2019

Morgan Baker · Nebraska Academy of Sciences

Overview

This project is on the effects of pharmaceutical waste on Daphnia magna. Scientists have been becoming more worried about chemicals from prescription drugs and over-the-counter medications that get into lakes, rivers, and streams. Only a fraction of these drugs get disposed of properly. Sewage treatment plants are not currently designed to remove pharmaceuticals from water, nor are the facilities that treat the water to make it suitable to consume. Although pharmaceutical pollution does not seem to be harming humans yet, disturbing clues suggest a negative effect on aquatic life. In this experiment, I tested the heart rate of Daphnia magna after three weeks of exposure to various pharmaceutical drugs at different concentrations. The drugs significantly increased the heart rate of the specimen.
