CASPER, Wyo. (AP) - A new study says higher pollution levels in southwest Wyoming from 2008 to 2011 drove more people to Sublette County clinics and doctors. Data released by the Wyoming Department of Health link elevated levels of ozone, a toxic pollutant, to increased visits to physicians, especially for respiratory complaints.
The area has for years seen higher levels of ozone, largely as a result of natural gas drilling activity. The study compared ozone data collected by the Wyoming Department of Environmental Quality to patient data collected in the county. It showed that for every 10 parts per billion ozone rose, respiratory-based visits to doctors rose 3 percent. The department isn't expected to make any recommendations based on the study.
