 particulate matter air pollution  (PM 2.5)–a type of pollution caused by microscopic particles that are 2.5 micrometers or smaller and made from solids and liquid droplets. The EPA offers the width of a single strand of hair as an example to understand the particle size. According to the study, the tiny size of these particles makes them inhalable, threatening damage to the respiratory system, and PM 2.5 is responsible for 85,000 to 200,000 excess or preventable deaths per year in the US.  Black Americans across all economic backgrounds are exposed to “greater than average concentrations” of this type of pollution with an exposure disparity of 21 percent. Latino and Asian Americans are also exposed to PM 2.5 at higher concentrations, while white Americans experience lower than average.
