Vehicle emissions are one of the largest sources of carbon monoxide and fine-particulate pollution along the Wasatch Front, says Sandy Daw, executive coordinator for the Governor's Clean Air Committee. Daw participated in a meeting for employees sponsored by UTA at Utah Valley Regional Medical Center on Monday.
"Because of the large growth expected (along the Wasatch Front) over the next five years, we're about to begin a large upturn in (carbon monoxide levels)," she said.That's troubling, particularly for Provo and Salt Lake County, which already are non-attainment areas for carbon monoxide.
Standards for pollutants such as carbon monoxide are established based on health risks for "most sensitive individuals." Who fits that category? About 75 percent of the population, Daw said, including:
- Individuals 6 to 18 years of age.
- Pregnant women.
- Recreational athletes.
- Individuals older then 55.
- People with health conditions such as heart disease.
Daw pointed out that most vehicle pollution is emitted by about 12 percent of the vehicles in the state - primarily older-model cars and those not kept in good running condition.
