Fri May 24 Unit 4 Field Study Procedures b. In the box under Select a Pollutant, select PM10. This refers to particulate matter that is less than 10 microns, or 0.01 mm, large. c. Enter the number of the Air Quality Index that you found for your chosen location. Then click Calculate. d. The boxes will display the concentration of that size particle in micrograms per cubic meter (µg/m³). The website will also list sensitive groups, health effects, and cautions. For example, in Madison, Wisconsin, on the date studied, the air was risky mostly for people with respiratory diseases. 4. Check daily and record your data. a. Each day during this field study, check the same online data for the same location. b. Create a table nine columns across and three rows down, such as the one shown. Each day of the field study will be represented by a column. One row will contain that day's Air Quality Index. Another row will contain that day's particulate pollutant concentration. The AQI may not be available for every day during the study. If that is the case, write "Data Not Available" in the appropriate box on the table.
