Analysis of air quality in Los Angeles showed that children’s health improved, while reducing smog.
Children who live in areas with more air pollution, more likely to get sick with asthma — most common chronic disease among young people. A study published in the journal of the American medical Association JAMA, showed that clean air is a key factor in the prevention of the disease.
Over the past two decades, air quality in Los Angeles has noticeably improved since more stringent rules to limit emissions from road transport. The study covered three different time periods: 1993-2001, 1996 and 2004, and 2006-2014. It turned out that the third period has significantly decreased the number of asthma attacks as the air was noticeably clear of particulate contamination.
