Social Vulnerability Index and Excess Blood Pressure Associated With PM2.5 Exceeding WHO Annual Standards

(A) Map of the census tract-level SVI and excess PM_2.5. (B) Estimated excess systolic blood pressure (mm Hg) associated with annual PM2.5 exposures exceeding the revised 2021 World Health Organization air quality guidelines (PM_2.5 ≥5 μg/m³) using estimates from interventional studies (top) and observational studies (bottom), by race and ethnicity and social vulnerability. NH = non-Hispanic; SVI = social vulnerability index.
