Higher concentrations of particulate matter smaller than 2.5 micrometers (PM2.5) was responsible for the deaths of 30,000 Americans between 1999 and 2015. A study published in the journal ME found deaths among women were slightly higher, while overall life expectancy was lowered by almost eight weeks. The effect was most noticeable around Los Angeles and some southern states, including Arkansas, Oklahoma and Alabama. It was most pronounced in counties with lower incomes and higher poverty. In total, 18.4 million deaths in the research period were from cardiovascular diseases, which could be associated with air pollution.
