Exercise 1: Air Pollution and Covid-19 The Covid-19 pandemic has caused a lot of lifestyle changes around the word due to quarantine efforts to hinder disease spread. Due to these changes, human activity has decreased ad resulted in improved air quality in certain areas. Write a 500-word essay selecting two of the air contaminants discussed in lab today and how their concentrations have changed as a result. You are required to use at least three sources to back of your claims and may use the aid of figures. Exercise 2: Air Pollution in Your Zip Code (Allen, Texas, 75013) 1, Go to https://www.airnow.gov/aqi/aqi-basics. What is the AQI and how does it work? 2, What are the five major pollutants used to determine AQI? 3, Now go to http://www.airnow.gov/ and enter your zip code. What is the current AQI for your zip code? What is the Primary Pollutant for your area? What warnings are given for each pollutant? 4, What is the forecast pollutant for the next few days? Are there any new pollutants or new warnings present? 5, Ground-level ozone is a common air pollutant in urban areas. What is the difference between ground-level ozone and stratospheric ozone? How is ground-level ozone formed? More information about ozone can be found at https://www.epa.gov/ground-level-ozone-pollution/ground-levelozone-basics#effects. Exercise 3: Mercury and Other Fish Advisories 1, Go to the following link https://www.epa.gov/choose-fish-and-shellfish-wisely/fish-and-shellfish-advisories-and-safe-eating-guidelines to learn more about fish consumption advisories. a.

Choose a body of water (possibly from your hometown) and download the advisory links to find out what contamination was present in the fish, as well as whether consumption is permissible or limited for certain species. a. Which body of water did you choose? b. What contaminants are present? c. What fish are under these advisories? 3, Once you find out what these contaminants are, do some extra research on the internet to find out the side effects and concerns associated with these compounds (page 11 http://fishadvisoryonline.epa.gov/docs/NLFA_Advisories_Where_You_Live_User_Guide.pdf and http://www.atsdr.cdc.gov/ has some basic information you may find helpful). a. Do any of these compounds bioaccumulate or biomagnify? What type of effects do they have on wildlife and humans? How does the presence of these compounds make you feel about the body of water and fish?
