Utah’s low-smoking population and high population density concentrated in mountain valleys, with intermittent industrial activity and frequent temperature inversions, have yielded unique opportunities to study air pollution. These studies have contributed to the understanding of the human health impacts of air pollution. The populated mountain valleys of Utah experience considerable variability in concentrations of ambient air pollution because of local emission sources that change over time and episodic atmospheric conditions that result in elevated concentrations of air pollution. Evidence from Utah studies indicates that air pollution, especially combustion-related fine particulate matter air pollution and ozone, contributes to various adverse health outcomes, including respiratory and cardiovascular morbidity and mortality and increased risk of lung cancer. The evidence suggests that air pollution may also contribute to risk of pre-term birth, pregnancy loss, school absences, and other adverse health outcomes.

在犹他州进行的历史和现代空气污染研究

犹他州的低烟人口和高人口密度集中在山谷中，间歇性的工业活动和频繁的温度反转，为研究空气污染提供了独特的机会。这些研究有助于理解空气污染对人类健康的影响。犹他州人口稠密的山谷在环境空气污染浓度方面存在相当大的变化，这是因为局部排放源会随着时间的推移而变化，而大气环境的偶发会导致空气污染浓度升高。犹他州的研究表明，空气污染，尤其是与燃烧有关的细颗粒物空气污染和臭氧，会导致各种不良健康后果，包括呼吸和心血管疾病的发病率和死亡率，以及罹患肺癌的风险增加。有证据表明，空气污染也可能导致早产，流产，失学和其他不利健康后果。
