Dr. David Allen, a
leading researcher on the Texas Air Quality Study II that ended this
October, helped identify regional air pollutants as being a major factor
that needs to be considered in updating Texas cities' air quality
regulation plans. Allen directs the university’s
Center for Energy and Environmental Resources, and helped compile
research findings from the study that were presented recently to the
Texas Commission for Environmental Quality to guide regulatory decisions.

Dr. David Allen with Jarett Spinhirne, a research engineer who runs
Allen’s air analysis lab at the Center for Energy and Environmental
Resources. In front of them is a device to which they have attached
stainless steel cannisters that contain air samples collected at
sites in Austin, Houston and other parts of central and eastern
Texas for the TexAQSII study. The tank of liquid nitrogen behind
that is used to cool the air sample down to -320 degrees Fahrenheit
to solidify the carbon-based chemical pollutants in the air sample
for further analysis.
