Our group uses cutting-edge analytical tools to learn about the unique chemical processes that happen when the atmosphere meets a solid or liquid surface.
Prof. Collins is always interested in talking to potential new research group members. Contact him here.
Are the two Air Quality Index (AQI) values different?
The airborne particulate matter (PM2.5) sensor on our campus only measures one kind of air pollutant, so the AQI is based on only a portion of the pollutants that actually can affect our health. However, there are many of these PM2.5 sensors that we can use to get a good sense of air quality right where we live, since PM2.5 levels can vary locally -- it just might not tell the whole air quality + health story.
The US EPA Air Quality index for the area around Lewisburg uses both PM2.5 and ground-level ozone to assess the AQI. This value is more relevant for our overall health because it captures two of the key air pollutants that can affect our health, but it is based on measurements that are farther away, so our local values are computed based on the (relatively few) sensors that are stationed around Central PA.
