The total number of years of life that would be saved over the next 100 years by reducing long-term PM2.5 exposure to background was estimated to be 916,000 life years. There may be some overlap between asthma emergency department visits among 0–14 year olds associated with PM2.5 exposure and respiratory hospital admissions among 0–14 year olds associated with PM10 exposure.
