Abstract
The purpose of this experiment was to determine the toxic effect plastics commonly found in the ocean have on marine life. This was tested using high density polyethylene, polyvinyl chloride and cellulose acetate. The hypothesis for the experiment is, if Daphnia magna are exposed to cellulose acetate, high density polyethylene, and polyvinyl chlorine then the toxicity of the plastics will cause it will have a higher chance of mortality and its heart rate will increase. To test this experiment the Daphnia magna were separated into 4 different treatment groups, 30 included in each group. Then, their heartbeats were measured under a microscope and recorded. Also, for each test heartbeats are tested, the number of Daphnia was also noted. Using a one-way ANOVA the variance was tested. It found that the variance between the control and any of the treatments, was significant and was extremely variant. When the treatment groups were compared against each other, their variance tended to be insignificant. The significance of this finding is that now further research can be done to examine the long term effects of the plastics in the ocean and it's possible effect on humans.
