Abstract: Long-term exposure to the fine particulate matter (PM2.5) is a risk factor for cardiorespiratory mortality. However, little known about its distribution and health impact in large cities low-middle-income countries where population has increased during last decades. This ecological study evaluated association between PM2.5 concentration adult mortality at intraurban census sector (CS) level of Colombia’s five most populated (2015-2019). We estimated incidence rate ratios (IRR; per 5µg/m3) by fitting negative binomial regressions smoothed Bayesian rates (BMR) on predicted from land use regression (LUR) models, adjusting CS demographic structure, multidimensional poverty index, spatial autocorrelation. median ranged 8.1µg/m3 Bucaramanga 18.7µg/m3 Medellín, whereas Bogotá had highest variability (IQR = 29.5µg/m3) (BMR 2,560 100,000). (IRR 1.15; 95%CI: 1.02; 1.31), without evidence clustering, cardiovascular 1.06; 1.01; 1.12) respiratory 1.07; 1.13) Medellín. Cardiorespiratory spatially clustered some Colombian was associated with long-term urban areas LUR models predictive accuracy. These findings highlight need incorporate high-quality, high-resolution assessments better understand air pollution inform public interventions environments.

As policymakers increasingly focus on environmental justice, a key question is whether emissions reductions aimed at addressing air quality or climate change can also ameliorate persistent pollution exposure disparities. We examine evidence from California’s aggressive vehicle control policy 2000 to 2019. find 65% reduction in modeled statewide average PM 2.5 on-road vehicles, yet for people of color and overburdened community residents, relative disparities increased. Light-duty are the main driver disparity, although smaller contributions heavy-duty vehicles especially affect some groups. Our findings suggest that continued trend will likely reduce concentrations absolute disparity but may not without greater attention systemic factors leading this disparity.

Adverse health impacts from outdoor air pollution occur across the United States, but magnitude of these varies widely by geographic region. Ambient pollutant concentrations, emission sources, baseline conditions, and population sizes distributions are all important factors that need to be taken into account quantify local burdens.
