National Cohort Study of Long-Term Exposure to PM_2.5 Components and Mortality in Medicare American Older Adults.

ABSTRACT: There is increasing evidence linking long-term fine particulate matter (PM_2.5) exposure to negative health effects. However, the relative influence of each component of PM_2.5 on health risk is poorly understood. In a cohort study in the contiguous United States between 2000 and 2017, we examined the effect of long-term exposure to PM_2.5 main components and all-cause mortality in older adults who had to be at least 65 years old and enrolled in Medicare. We estimated the yearly mean concentrations of six key PM_2.5 compounds, including black carbon (BC), organic matter (OM), soil dust (DUST), nitrate (NO₃^-), sulfate (SO₄^2-), and ammonium (NH₄⁺), using two independently sourced well-va
