BACKGROUND: Ambient air pollution from traffic increases cardiovascular morbidity and mortality and is associated with coronary artery calcification. Whether this increased risk is mediated by severity of coronary artery disease (CAD) remains unknown. METHODS: In this pilot study, the relationship between living near a major roadway and multivessel CAD confirmed by invasive coronary angiographic was explored. Subjects undergoing coronary angiography in the Los Angeles metropolitan area in 2009-10 were randomly selected. Investigators blinded to the exposure status reviewed coronary angiograms. Subjects were categorized as having: absence of or non-obstructive CAD, 1-vessel, 2-vessel, or 3-vessel CAD based upon the number of major epicardial vessels with > 70% stenoses. The distance from each subject's residence to the nearest major road was calculated in meters. Multivariate logistic regression was used to explore the relationship between severity of CAD and distance to major roadway. RESULTS: There were 642 subjects undergoing coronary angiography. The mean age (SD) was 64 years (12) and 36% were female. In multivariate analysis log-road distance was a predictor of multivessel CAD, odds ratio (OR) = 0.85 (95%CI, 0.75-0.98; p=0. 02) after adjusting for age, gender, hypertension, and diabetes, and smoking status. Other predictors of multivessel CAD included from the multivariate logist model were: male gender (OR, 3.00, 95% CI, 2.06-4.39; p<0.001), diabetes (OR, 2.49; 95% CI, 1.75-3.54; p<0.001), and hypertension 2.58; 95%CI, 1.28-5.21; p=0.008). The most severe form of CAD, >50% stenosis of the left main artery, was observed in 6.6% of the cohort. In a multivariate model, age (P = 0.002) and diabetes (P = 0.002) were significant predictors of severe left main disease; there was a trend for log-road distance (OR, 0.83; 95% CI, 0.67-1.02; P = 0.079) with left main disease. CONCLUSIONS: Multivessel CAD was strongly associated with traditional risk factors. After adjusting for these factors, living near a major roadway was also a predictor. This study demonstrates the feasibility of exploring the association between angiographic CAD and traffic pollution. Additional studies are needed to better understand the mechanisms underlying the increase in adverse cardiovascular events from air pollution.

The Relationship

Ambient air pollution is a risk factor for both acute and chronic diseases and poses serious health threats to the world population. We aim to study the relationship between air pollution and all-cause mortality in the context of a city-state exposed to the Southeast Asian haze problem. The primary exposure was ambient air pollution, as measured by the Pollutants Standards Index (PSI). The outcome of interest was all-cause mortality from 2010–2015. A time-stratified case-crossover design was performed. A conditional Poisson regression model, including environmental variables such as PSI, temperature, wind speed, and rainfall, was fitted to the daily count of deaths to estimate the incidence rate ratio (IRR) of mortality per unit increase in PSI, accounting for overdispersion and autocorrelation. To account for intermediate exposure effects (maximum lag of 10 days), a distributed lag non-linear model was used. There were 105,504 deaths during the study period. Increment in PSI was significantly associated with an increased risk of mortality. The adjusted IRR of mortality per the 10-unit increase in PSI was 1.01 (95%CI = 1.00–1.01). The lag effect was stronger when PSI was in the unhealthy range compared to the good and moderate ranges. At lag = 7 days, PSI appeared to have an adverse effect on mortality, although the effect was not significant. These findings provide evidence on the general health hazard of exposure to air pollution and can potentially guide public health policies in the region.

The Relationship

Ambient air pollution represents a global health crisis, leading to 7 million annual deaths worldwide. The rise of a “global environmental regime” manifests in the widespread adoption of environmental policies and laws to reduce ambient air pollution, but debate remains whether they have any effect. Scholars argue that the relationship between the global environmental regime and air pollution depends on the penetration of the global environmental regime. In this analysis, I argue that the relationship between the global environmental regime and air pollution levels is contingent on a country’s position in the world-system. Using fixed effects panel analyses of 144 countries from 1990 to 2010, I find embeddedness in the global environmental regime does predict lower national air pollution levels. This effect, however, is smaller in semi-peripheral and peripheral countries. These findings contribute to an emerging body of scholarship integrating world society and world systems approaches in the study of the environment.

The Relationship

Transportation sector has a very big influence in air pollution. Increase the number of vehicles will caused higher air pollution, such as NO2. The increase in ambient air pollution is feared to have an impact on indoor air pollution. This study purposed is to determine the relationship between  NO2 concentration in ambient to indoor air.  This study used kuantitatif methods with purposive sampling for one month in Simpang Pulai Jambi City.  The relationship between NO2 concentration of ambient air and indoor air was analyzed using simple pearson correlation. The result showed that there was no significant relationship between NO2 concentration in ambient to indoor air with correlation value (r) is 0,437.  The highest NO2 concentration found on the third week in ambient 109,139 µg/m3and indoor air 70,133 µg/m3.  From analysis in one month showed that NO2 concentration in Simpang Kawat Jambi City still meet the air quality standard (150 μg / m3) in Government Regulation Number 41 Year 1999 about Air Pollution Control.
