A multi-phase study on air quality surrounding Los Angeles International Airport has found that major air pollutant levels do not exceed national and state air quality standards.
The recently released Air Quality and Source Apportionment Study report for LAX was designed and continuously reviewed by a technical working group of air quality scientists and researchers on the federal, state and local levels, as well as community organizations, airport officials said.
According to the study, the levels of all major air pollutants measured, including carbon monoxide, nitrogen oxide, sulfur dioxide, and fine particulate matter, were within national and California air quality standards. The study also found that concentrations of all major as well as other pollutants measured were comparable or lower than concentrations in other similar areas of Los Angeles.
The study, which was a multi-year project, is the first of its kind in the nation to comprehensively assess a major airport’s contribution to ambient air quality levels in communities nearby, airport officials said.
“During the time it took to conduct this study, there were many instances when it became clear we were pushing the capabilities of science to definitively allocate air emissions sources and distribution,” said Airport Commission President Michael Lawson. “LAWA appreciates the hard work of the scientists who conducted the study and the technical working group who helped design it. Because of their efforts, we know much more than when we started this process.”
A variety of monitoring equipment and modeling techniques were used to complete the study. The monitoring was done in two six-week sampling seasons in winter/spring 2012 and summer 2012. More than 121,000 data points were collected at 17 core, satellite, and gradient monitoring sites in the communities adjacent to LAX, including El Segundo, Lennox, Playa del Rey and Westchester, officials noted.
“LAWA deserves credit for completing this air quality study. It took a lot of time, effort and resources. The researchers gathered more information about the air quality impacts of airport operations than anyone has ever collected,” noted Joe Lyou, president and CEO of Coalition for Clean Air, and South Coast Air Quality Management District Governing Board member.
“There is a lot of important information in this study. Some of it is good news. Some of it raises concerns that suggest where to focus next. All of it is useful.”
The report, which was presented to the Board of Airport Commissioners at its June 18 meeting, is available for public review online at www.lawa.org/airqualitystudy,  at Councilman Bill Rosendahl’s district office, 7166 W. Manchester Ave. in Westchester, and at the Westchester-Loyola Village Branch Library, 7114 W. Manchester Ave. in Westchester.
