Task 4: Analysis of survey data on ozone alert days
The Air Quality Index (AQI) and the associated ozone alert system is one of a number of programs that provide information to the public about an environmental threat. This information can help the public in two general ways. People can use this information to decide whether and how much they need to protect themselves by limiting their own exposure. In addition, the information could encourage people to take whatever steps they can to reduce the level of the environmental threat for others. For example, in the case of ozone pollution people could limit time outdoors to reduce their own exposure and limit the amount they drive during the day to reduce the overall level of ozone pollution in the region.
