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.

Birth Records

There is a growing body of research on the association between ambient air pollution and adverse birth outcomes. However, people in high income countries spend most of their time indoors. Pregnant women spend much of that time at home. The aim of this study was to investigate if indoor air pollutants were associated with poor birth outcomes. Pregnant women were recruited prior to 18 weeks gestation. They completed a housing questionnaire and household chemical use survey. Indoor pollutants, formaldehyde (HCHO), nitrogen dioxide (NO2) and volatile organic compounds (VOCs), were monitored in the women’s homes at 34 weeks gestation. Gestational age (GA), birth weight (BW) and length (BL) and head circumference (HC) were collected from birth records. The associations between measured pollutants, and pollution surrogates, were analysed using general linear models, controlling for maternal age, parity, maternal health, and season of birth. Only HCHO was associated with any of the birth outcomes. There was a 0.044 decrease in BW z-score (p = 0.033) and 0.05 decrease in HC z-score (p = 0.06) for each unit increase in HCHO. Although HCHO concentrations were very low, this finding is consistent with other studies of formaldehyde and poor birth outcomes.

<p>In addition to many recent actions taken to reduce emissions from energy production, industry, and transportation, a new campaign substituting residential solid fuels with electricity or natural gas has been launched in Beijing, Tianjin, and other 26 municipalities in northern China, aiming at solving severe ambient air pollution in the region. Quantitative analysis shows that the campaign can accelerate residential energy transition significantly, and if the planned target can be achieved, more than 60% of households are projected to remove solid fuels by 2021, compared with less than 20% without the campaign. Emissions of major air pollutants will be reduced substantially. With 60% substitution realized, emission of primary PM2.5 and contribution to ambient PM2.5 concentration in 2021 are projected to be 30% and 41% of those without the campaign. With 60% substitution, average indoor PM2.5 concentrations in living rooms in winter are projected to be reduced from 209 (190-230) μg/m3 to 125 (99-150) μg/m3. The population-weighted PM2.5 concentrations can be reduced from 140 μg/m3 in 2014 to 78 μg/m3 or 61 μg/m3 in 2021 given that 60% or 100% substitution can be accomplished. Although the original focus of the campaign was to address ambient air quality, exposure reduction comes more from improved indoor air quality because approximately 90% of daily exposure of the population is attributable to indoor air pollution.

ABSTRACTTtransportation is one of the factors that have a major influence in air quality decline. Air pollution is not only happening outside the room and will mobilization activities of motor vehicles, but it can affect air quality in space. One of the pollutant gas produced from vehicles is the concentration of Nitrogen Dioxide (NO2). This allows an exposure that will impact on public health. The purpose of this study is to determine the relationship of NO2 air ambient concentration (outdoor) to indoor air (indoor) in Simpang Jelutung Red Lights area. The method used in this study is quantitatif method. Data collection using sampling NO2 concentration in outdoor and indoor. The relationship between outdoor and indoor NO2 concentrations was analyzed using Pearson correlation. This is in line with the small influence of air NO2 concentration in space on public health. Result shows that all of the sample is still categorized either or not passing the air quality standard (150 μg / m3) in Government Regulation Number 41 Year 1999. The correlation analysis result  show relationship NO2 concentration between ambient air (outdoor) to indoor air was 13%, which means that correlation relationship is very weak.  Keywords:     Ambient air, indoor air, NO2 concentration

The most typical air pollutants including PM10, CO, SO2, NOx are monitored at different sites indoor (basement, shopping malls) and outdoor (ambient air) of several complex buildings which are used for different purposes of resident, office, and shopping malls in Hanoi. The results show that the indoor air pollution concentrations tend to be higher than the corresponding pollutants of the ambient air. The results show the highest concentrations are in RC building for the same category of floor comparing to the other two buildings. Pollutant concentrations at basement for parking is the highest with the values of PM10, SO2, NOx, CO of 67.1 ± 21.2 µg/m3, 224.8 ± 34.9 µg/m3, 287.3 ± 136.3 µg/m3, 22,372.5 ± 2,324.5 µg/m3, respectively. The high concentration of indoor air pollutants are harmful for human health, especially for those who have longer exposure time.

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.
