Natural causes of air pollution cannot usually be abated, however, efforts can be provided for the populations exposed.
Nevada is affected by unpredictable wildfire smoke. An accumulation of pollutants occur due to the state's topography of basins and ranges, as well as temperature inversions. There is also airborne mercury, associated with gold mineral deposits. Nevada is the largest producer of gold in the United States.
I also work in Hawaii, which is affected by volcanic air pollution, "vog," which is primarily composed of sulfate particles and sulfur gases. Documented health effects in the exposed population include increased incidence of acute airway problems in children, exacerbation of asthma, acute bronchitis, pharyngitis, and upper respiratory diseases.
Natural causes of air pollution cannot usually be abated, however, efforts can be provided for the populations exposed. For example, it's important to monitor the health of the population in a correct epidemiological manner. Early detection through screening can allow early initiation of treatment and prevent disability and lost quality of life years. Also, there are ways to minimize exposure. In the small town of Pahala in Hawaii, the vog is minimal from 11am until 7pm—therefore, children can have outdoor recess, sports activities and athletes can train without exposure. In addition, air conditioning has been found effective to scrub this pollutant.
