The Los Angeles region achieved its lowest levels ever for unhealthy ozone days and for year-round particle pollution but still remains among the most polluted in the country, the American Lung Association said Wednesday in its State of the Air 2017 report.
The Los Angeles region topped the national list for number of unhealthy days of ozone pollution, ranked fifth for year-round particle pollution and ninth for short-term particle pollution, a statement said.
The State of the Air 2017 report is based on air quality monitoring data collected in 2013-2015, the most recent years available. The report focuses on ozone and particle pollution — the most widespread forms of pollution threatening public health, it said
“Our state’s air quality continues to hit unhealthy levels each year, putting Californians at risk for premature deatg and other serious health effects such as asthma, COPD, and lung cancer,” said Olivia Diaz-Lapham , president and CEO of the American Lung Association in California.
