April 29th- Pollution Index Chart

The purpose of the pollution index chart is to figure out what range of pollution water has, from low to high levels of pollution. The benefits are that it can show if certain types of organisms would be able to handle living in certain bodies of water, and it can warn one to not put certain types of organisms if water is too polluted for them to handle. Its shortcomings are that it does not include every type of algae and therefore some of the levels of pollution may be slightly skewed. The effect of organic pollution on algae is that certain types of algae, such as euglena, are more likely to live in areas with more pollution and can handle higher levels of pollution than other types of algae that could not survive in high levels of organic pollution.
