Air pollution diminishing air quality at Devils Postpile National Monument
Date:4/23/2013

RIVERSIDE, Calif.Air pollution from wildland fires and urban and agricultural areas in California is diminishing air quality at Devils Postpile National Monument, according to a recent study published in the journal Atmospheric Environment.

Dr. Andrzej Bytnerowicz, a research ecologist from the U.S. Forest Service's Pacific Southwest Research Station, and a team of scientists measured air quality at Devils Postpile National Monument in the eastern Sierra Nevada and found occasionally high concentrations of ozone caused by wildland fires and air pollution from the California Central Valley and the San Francisco Bay Area. Ozone air pollution was measured at the Devils Postpile during the 2007 (low-fire) and 2008 (high-fire) summer seasons.

Key findings include:

  • Higher ozone peak concentrations in the high-fire year were attributed to emissions of ozone precursors (nitrogen oxides and volatile organic compounds) from wildland fires upwind of Devils Postpile in addition to polluted air traveling from the California Central Valley and the San Francisco Bay Area.

  • The highest ozone levels occurred when air masses swept through the San Francisco Bay Area and the California Central Valley in a northwest to southeasterly direction before reaching Devils Postpile at low altitudes. Both local generation of ozone and long-range transport of polluted air from the Central Valley occasionally caused increased air pollution at Devils Postpile.

  • The lowest ozone pollution occurred when air masses traveling over the Pacific Ocean passed from west to east at high altitudes, sweeping above the polluted air masses of the Central Valley.

  • Ozone concentrations exceeded the California air quality standards during the two study years, which may have contributed to the exceedance of federal standards (which are calculated for three-year periods). These levels pose a risk to sensitive individuals and
