Short-term mortality rates during a decade of improved air quality in Erfurt, Germany
The aim of the study was to investigate the association of ambient air pollution and daily mortality in Erfurt, Germany, over a 10.5-year period after the German unification, when air quality improved.Oily droplets in ambient air of Shillong
An attempt has been made to quantify the relative abundance and size distribution of oily-droplets in the ambient air of Shillong using an optical microscope. The sampling was carried out at controlled, moderate traffic, high traffic, traffic intersections, industrial estates and elevated specific locations in different seasons during 1998-2000. It …Evaluating the effects of ambient air pollution on life expectancy
Air pollution is an important determinant of population health. In an analysis that correlates reductions in fine particulate matter (i.e., particles less than 2.5Fine-particulate air pollution and life expectancy in the United States
Exposure to fine-particulate air pollution has been associated with increased morbidity and mortality, suggesting that sustained reductions in pollution exposure should result in improved life expectancy. This study directly evaluated the changes in life expectancy associated with differential changes in fine particulate air pollution that occurred in the United States …Air quality interventions and spatial dynamics of air pollution in Delhi and its surroundings
The paper examines the spatial distribution of air pollution in response to recent air quality regulations in Delhi, India. Air pollution was monitored at 113 sites spread across Delhi and its surrounding areas from JulyAssociations between PM2.5 and heart rate variability are modified by particle composition and beta-blocker use in patients
It has been hypothesized that ambient particulate air pollution is able to modify the autonomic nervous control of the heart, measured as heart rate variability (HRV) . Previously we reported heterogeneous associations between particulate matter with aerodynamic diameter < 2.5Urinary levoglucosan as a biomarker of wood smoke exposure: Observations in a mouse model and in children
Biomass smoke is an important source of particulate matter (PM) , and much remains to be discovered with respect to the human health effects associated with this specific PM source. Exposure to biomass smoke can occur in one of two main categories: short-term exposures consist of periodic, seasonal exposures typified …Mortality in the medicare population and chronic exposure to fine particulate air pollution in urban centers (20002005)
Prospective cohort studies constitute the major source of evidence about the mortality effects of chronic exposure to particulate air pollution. Additional studies are needed to provide evidence on the health effects of chronic exposure to particulate matter ? 2.5 ?m in aerodynamic diameter (PM2.5) because few studies have been carried …On the shelf?
CentreParticulate air pollution as a risk factor for ST-segment depression in patients with coronary artery disease
The association of particulate matter (PM) with cardiovascular morbidity and mortality is well documented. PM-induced ischemia is considered a potential mechanism linking PM to adverse cardiovascular outcomes.Right heart pressure increases after acute increases in ambient particulate concentration
We explored the association between acute changes in daily mean pulmonary artery (PA) and right ventricular (RV) pressures and concentrations of ambient fine particulate matter [PM with aerodynamic diameter ? 2.5 ?m (PM2.5)] as an explanation for previous associations between congestive heart failure (HF) hospital admissions and PM. In the …Road risk
living close to main roads could put your child at risk. A study conducted by German researchers in the Munich metropolitan area showed that traffic- related pollution could be responsible for increasing the risk of allergy and respiratory diseases by more than 50 per cent in children. Parents were asked …Diesel exhaust inhalation elicits acute vasoconstriction in vivo
Traffic-related air pollution is consistently associated with cardiovascular morbidity and mortality. Recent human and animal studies suggest that exposure to air pollutants affects vascular function. Diesel exhaust (DE) is a major source of traffic-related air pollution. The goal of this particular study was to study the effects of short-term exposure …A Comparison of particulate matter from biomass-burning rural and non-biomass-burning urban households in Northeastern China
Biomass fuel is the primary source of domestic fuel in much of rural China. Previous studies have not characterized particle exposure through timeAtopic diseases, allergic sensitization, and exposure to traffic-related air pollution in children
To assess the relationship between individual-based exposure to traffic-related air pollutants and allergic disease outcomes in a prospective birth cohort study during the first 6 years of life.Air pollution, airway inflammation, and lung function in a cohort study of Mexico city schoolchildren
In this study the researchers assessed the association of short-term air pollutant exposure with inflammatory markers and lung function.Elevated ambient air zinc increases pediatric asthma morbidity
This study aimed to investigate the relationship between outdoor ambient air PM2.5 zinc levels and urgent health care utilization for children living in an urban area.EU agrees on air quality
European states have agreed on legally binding limits on the airborne concentration of ultra-fine dust. The new directive on ambient air quality sets standards for reducing the concentration of fine particles known as PM2.5. Ultrafine particulate matter poses the biggest threat to human health as it can work its way …Ambient particulate pollutants in the ultrafine range promote early atherosclerosis and systemic oxidative stress
Air pollution is associated with significant adverse health effects, including increased cardiovascular morbidity and mortality. Exposure to particulate matter with an aerodynamic diameter of PM2.5 increases ischemic cardiovascular events and promotes atherosclerosis. Moreover, there is increasing evidence that the smallest pollutant particles pose the greatest danger because of their high …Air pollution due to burning of agriculture residue
Residue burning practice is followed in major Indian states of Uttar Pradesh and Punjab. Agricultural residue burning in the fields and used otherwise for rural domestic needs is responsible for a large number of toxic emissions, which are a health hazard. The main pollutants contributed from biomass burning are aerosols …
