These data were collected with portable, battery-powered monitors that are often used in an emergency response because they give immediate readings; however, the data obtained from these monitors could not easily be compared with the EPA standards. EPA does not use data from these types of monitors either for compliance purposes or for generating routine air quality advisories, noted Schwab. Even so, to provide the public with a point of reference, EPA compared the results with its air quality index for inhalable coarse particles, also known as PM 10.
