Big disparities in air pollution detected in L.A. neighborhoods (LA Times)
Big disparities in air pollution detected in L.A. neighborhoodsBy Tony Barboza
December 13, 2013
Smog is an irritation for anyone living in Los Angeles, but exactly where in the city you live can make a huge difference in your in your exposure to the tiniest air pollutants, a new study has found.
The study by UCLA researchers compared four Los Angeles neighborhoods and found striking disparities in levels of air pollutants known as ultrafine particles, even over short distances.
A zone of the Westside neighborhood of Mar Vista that sits downwind of Santa Monica Airport, for instance, has much higher levels of those pollutants in the air than the Eastside’s freeway-choked Boyle Heights, according to the study.
UCLA researchers drove an electric Toyota RAV4 equipped with air pollution monitors through residential streets in Boyle Heights, downtown, West Los Angeles and a part of Mar Vista known as North Westdale.
