The area that makes up Los Angeles-Long Beach-Riverside is the worst in terms of ozone pollution, according to the “State of the Air 2016″ report released by the American Lung Association on last Wednesday.
However, the analysis reveals that there are also improvements in air quality.
According to the study, Los Angeles County recorded 109 unhealthy ozone days in 2015, compared to a decade ago when there were 159; Riverside County had 140, compared to 191 in 2005 and Orange County recorded nine, compared to 38 in 2005.
The county where the air condition is worse was San Bernardino, which had 153 days with high prevalence of these particles in 2015, compared to 203 in 2005
The report bases its findings on records of contamination during 2012-2014.
Ozone and particle pollution are two of the most common pollutants that can be fatal to public health.
Persistent pollution problems in California are mainly due to emissions from means of transportation such as cars, trucks and diesel buses, locomotives, ships, agricultural equipment and other sources such as oil refineries, factories, burning firewood, in residential areas and forest fires. Weather conditions, heat and California geography facilitate the formation of smog and soot.
While many California cities appear among the top 10 with the worst air pollution, for several cities it was the cleanest year to date as regards of ozone or particle pollution. This is the case of Los Angeles, which obtained the lowest levels of air pollution in the 17 years that “State of the Air” has been published, the study says.
“Thanks to California’s cleaner vehicles and fuels and other innovative clean air policies, we’re seeing steady progress in our fight for cleaner air,” said Olivia J. (Gertz) Diaz-Lapham, President and CEO of the American Lung Association in California. “However, more than 80 percent of Californians –32 million residents – still live in counties with unhealthy air during certain parts of the year.” We simply must do more to protect the health of Californians.”
Statewide, the metropolitan area of Bakersfield fell again on the top spot as the most polluted area in the country due to particle pollution.
The analysis shows that, despite advances, more than 80% of Californians are still in at-risk situation due to an air with an adverse effect for health
Specifically, out of the 10 cities with the worst air pollution in the United States, the metropolitan areas of California are classified as follows:
