Recognition of polluted outdoor air as a threat to human health can be traced back at least
2400 years, in the book Airs, Waters, and Places attributed to Hippocrates, a Greek …

Background Long-term exposure to ambient air pollution has been associated with
premature mortality, but associations at concentrations lower than current annual limit …

Background Exposure to ambient air pollution increases morbidity and mortality, and is a
leading contributor to global disease burden. We explored spatial and temporal trends in …

Background Long-term improvements in air quality and public health in the continental USA
were disrupted over the past decade by increased fire emissions that potentially offset the …

Fine particulate matter (PM2. 5) air pollution has been recognized as a major source of
mortality in the United States for at least 25 years, yet much remains unknown about which …

Background: Ambient fine particulate air pollution with aerodynamic diameter≤ 2.5 μ m (PM
2.5) is an important contributor to the global burden of disease. Information on the shape of …

Background Most studies of long-term exposure to outdoor fine particulate matter (PM 2· 5)
and cardiovascular disease are from high-income countries with relatively low PM 2· 5 …

Air pollution levels are uneven within cities, contributing to persistent health disparities
between neighborhoods and population sub‐groups. Highly spatially resolved information …

Background Exposure to particulate matter (PM 2.5) is a major risk factor for morbidity and
mortality. Yet few studies have examined patterns of population exposure and investigated …

In the past decade, particulate matter with aerodynamic diameter less than 2.5 μm (PM 2.5)
has reached unprecedented levels in China and posed a significant threat to public health …
