Air Toxic Levels
Reduce all monitored air toxics to levels within state health guidelines by 2015.
There has been a 37 percent drop in benzene levels in metro area air since 2007, with a 26 percent drop from 2010 to 2011 alone. This drop can, in part, be attributed to increased automobile fuel efficiency. Benzene levels continue to stay below the health benchmarks.
In 2011, formaldehyde levels remained above the sustainability indicator and health benchmark. Formaldehyde levels did drop by 16 percent in 2011. This was the first drop for formaldehyde levels in 3 years. Sources of formaldehyde include power plants, manufacturing facilities, and automobile exhaust.
