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 …
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.
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 …
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 …
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 …
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.
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.
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 …
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 …
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 …
Crop residue burning results in the emission of many a toxic pollutants. These emissions can travel long distances affecting thereby the entire region. Due to these emissions the air quality of the region worsens, which results in nose and throat itching and burning, and irritation of the airway tract.
There's good news and bad news when it comes to air quality in Israel. On the one hand, Israel's annual monitoring report for 2006 reveals improvements in air pollution, especially when it comes to pollution from transportation sources in Tel Aviv and Jerusalem. On the other hand, the situation is …
With booming industries, Beijing finds it difficult to control SO2 and particulate matter. NO2 and toxic hydrocarbons add to its problems. After seven years of controls, SO2 and CO are down by nearly 25 per cent, but NOx is down by 17 per cent and PM10 levels marginally. Inhalable particles …
Living close to a busy road can damage your heart - and now we're closer to understanding why. Previous studies had suggested that people living in polluted areas are more at risk of heart disease. For example, a study published in The New England Journal of Medicine last year showed …
Urban populations are exposed to a high level of fine and ultrafine particles from motor vehicle emissions which affect human health. To assess the hourly variation of fine particle (PM2.5) concentration and the influence of temperature and relative humidity (RH) on the ambient air of Lucknow city, monitoring of PM2.5 …
A large body of epidemiologic literature has found an association of increased fine particulate air pollution (PM2.5) with acute and chronic mortality. The effect of improvements in particle exposure is less clear. Earlier analysis of the Harvard Six Cities adult cohort study showed an association between long-term ambient PM2.5 and …
the Central Pollution Control Board (cpcb), India's apex pollution monitoring body, has decided to initiate monitoring particles less than 2.5 micron in size (pm2.5) in the ambient air of ten critically polluted cities from 2005. It has also proposed to bring ten more cities under this scanner every year after …
