Abstract Identifying sources of air pollution exposure is crucial for addressing their health impacts and associated inequities. Researchers have developed modeling approaches to resolve source‐specific application in assessments, epidemiology, risk environmental justice. We explore six assessment approaches: Photochemical Grid Models (PGMs), Data‐Driven Statistical Models, Dispersion Reduced Complexity chemical transport (RCMs), Receptor Proximity Exposure Estimation Models. These models been applied estimate from such as on‐road vehicles, power plants, industrial sources, wildfires. categorize these based on assessing emissions atmospheric processes (e.g., statistical or first principles), units (direct physical measures indirect measures/scaled indices), temporal spatial scales. While most the studies we discuss are United States, methodologies applicable other countries regions. recommend identifying key that determine a given source using model sufficiently accounts processes. For instance, PGMs use principles parameterizations provide variability concentration units, although within attribution introduce uncertainties relative base difficult evaluate. Evaluation important but difficult—since observe, direct evaluation methods involve comparisons with alternative models.

The most up-to-date estimate of the global burden disease indicates that ambient air pollution, including fine particulate matter and ozone, contributes to an estimated 5.2 million deaths each year. In this review, we highlight challenges in estimating population exposure pollution attributable health risks, particularly low- middle-income countries among vulnerable populations. To protect public health, evidence so far confirms urgent needs prioritize interdisciplinary research on risk assessment develop evidence-based intervention policies communication strategies. Here, synthesize emerging supporting monitoring evaluation progress implementation Global Air Quality Guidelines prepared by World Health Organization.

Implications for greenhouse gas (GHG) emissions, air quality, health examined through an environmental justice lens. Electrification of light-, medium-, heavy-duty trucks assessed to identify scenarios associated with highest benefits most disadvantaged communities. Using spatially temporally resolved a chemical transport model, changes pollutant concentrations under electric truck estimated at 1-km2 resolution. Heavy-duty electrification reduces ambient black carbon nitrogen dioxide on average by 10 14%, respectively, GHG emissions 10.5%. It achieves reduction premature mortality attributable fine particulate matter chronic exposure (around 200 cases per year) compared light- medium-duty (less than 150 each).

In the United States (US), neonatal intensive care units (NICUs) monitor and treat newborns for a variety of adverse health concerns including preterm status, respiratory distress restricted growth. As such, NICU admission is an integrated measure risk. We linked 2018 US national birth registry data among singleton births with satellite modelled air pollution levels month prior to examine whether late-pregnancy exposure ambient pollutants associated outcomes. Regardless season, higher nitrogen dioxide (NO2) fine particulate matter < 2.5 microns (PM2.5) increased likelihood 30–35% NO2 11–22% PM2.5 even after adjustment parental characteristics. Results ozone were inconsistent largely null or reduced risk except summer months. Despite relatively low-moderate levels, traffic-related near end pregnancy appear increase overall risks newborns, underscoring need reduce prenatal pollutants.

Nitrogen dioxide (NO2) pollution is associated with adverse health effects, but its spatial variability between ground monitors poorly characterized. NO2 column observations from the Tropospheric Monitoring Instrument (TROPOMI) have unprecedented resolution and high accuracy over globe. Land-use regression (LUR) models predict surface-level relevance for epidemiological environmental justice studies. We use TROPOMI columns in a land model to improve surface concentration estimates United States. The LUR predictions improved correlation (Adj.

Removing decreased by 29.1%, 8.1 times impact of removing road system information. These findings reveal that novel Earth observing satellites can enhance surveillance capturing variation without relying heavily on other sources.

Introduction: Fine particulate matter (PM 2.5 ) air pollution is a leading environmental cause of morbidity, premature mortality, and loss human capital. Western Pennsylvania experiences elevated PM concentrations due to industrial automotive emissions unique geography. Objective: To assess the relationship between annual mean concentration social deprivation at census block group level in eight counties Pittsburgh Metropolitan Statistical Area (Allegheny, Armstrong, Beaver, Butler, Fayette, Lawrence, Washington, Westmoreland). Methodology: 2016 Aerosol Optical Depth modeled data were obtained 1 × km resolution from National Aeronautics Space Administration Socio-Economic Data Applications Center spatially joined 2,008 groups that comprise Area. Using University Wisconsin Deprivation Index, stratified into deciles ranging (least deprived) 10 (most deprived). A pairwise comparison was conducted examine estimates within across deciles. Results: The average ambient for 8.54 ± 0.46 µg/m 3 , with block-group 5.59 15.90 . We identified statistically significant, positive association deprivation: 1, representing least deprived neighborhoods, had lowest 8.70 µg/m³. In contrast, 10, most areas, highest 9.58 µg/m³ only significantly higher than all other exposure remained even after applying false discovery rate correction. Conclusion. Pennsylvania, associated deprivation. Our results indicate area urban US Census strongest areas high levels Future policy interventions should prioritize addressing needs minority communities are disproportionately exposed pollution.

Abstract Neighborhood quality affects both socioeconomic factors and exposure to carcinogenic environmental pollutants, but the impacts of these on racial disparities in colorectal cancer mortality are not well described. We used Centers for Disease Control Prevention Environmental Justice Index social vulnerability module, burden module (EBM), combined social–environmental score (SER) assess relationships with by race age Metropolitan Detroit Cancer Surveillance System. Among 13,505 patients [9,727 non-Hispanic White (NHW) 3,778 Black (NHB)], EBM quartile 4 versus 1 was more strongly associated among NHB early-onset (EO) cases than NHW EO [NHB: HR = 1.98, 95% confidence interval (CI), 1.20–3.26; NHW: 1.40, CI, 0.88–2.25]. SER (NHB: 1.76, 0.93–3.31; 1.53, 0.79–2.96) compared later-onset 1.15, 0.87–1.52; 1.39, 1.17–1.65) regardless race. These associations were strongest colon tumors rectal (EO EBM: 2.08, 1.24–3.48 vs. rectum 1.03, 0.64–1.66; SER: 2.57, 1.38–4.79 0.84, 0.48–1.45). results suggest combination socio-environmental burdens contributes metropolitan Detroit.
