Study: Cooking food is impacting outdoor air quality
It’s hard to resist the delicious smell of food cooking at restaurants, food trucks and street vendors across Los Angeles. However, a new government study suggests that those aromas may be negatively impacting air quality. Researchers from NOAA, the National Oceanic and Atmospheric Administration, have released their findings from a multiyear study of what they call “underappreciated sources” of urban air pollution. They focused on three cities: L.A., Las Vegas and Boulder, Colorado, where they measured human-caused volatile organic compounds (VOCs) related to cooking. “If you can smell it, there’s a good chance it’s impacting air quality,” researchers summarized. Seeing orange and white lines on the freeway? Here’s what they mean “Over the years, we’ve measured all sorts of different VOCs across the U.S. from different sources, like vehicles, wildfire smoke, agriculture, and consumer products,” wrote Matt Coggon, the study’s lead author. “We kept seeing a specific class of compound in the urban measurements, what we call long-chain aldehydes, that we couldn’t explain from these other sources.” Researchers found that Las Vegas, which has one of the highest densities of restaurants in the U.S., has
