A recent research study by Dr. Rima Habre took a detailed look at the short-term health impacts caused by breathing in ultrafine particulate (UFP) matter that is emitted from aircraft activity at the Los Angeles International Airport (LAX). Several years ago, USC researchers identified a clear pattern of UFP emissions from takeoff and landing aircraft activities at LAX. Levels of the dangerous UFPs were found to be 4 to 5 times greater than background levels in downwind communities. “Ultrafine particulate matter is known to contribute to reduced lung function, and airway inflammation in individuals with asthma.”

Planes’ exhaust could be harming communities up to 10 miles from LAX

“High levels of potentially harmful exhaust particles from jets using Los Angeles International Airport have been detected in a broad swath of densely populated communities up to 10 miles east of the runways, a new air quality study reported Thursday. The research, believed to be the most comprehensive of its type, found that takeoffs and landings at LAX are a major source of ultrafine particles. They are being emitted over a larger area than previously thought, the study states, and in amounts about equal in magnitude to those from a large portion of the county’s freeways. It further concludes that areas affected by aircraft exhaust at major airports in the U.S. and other parts of the world might have been seriously underestimated.
