BACKGROUND A number of epidemiological studies have been conducted to research the adverse effects of air pollution on mortality and morbidity. Hypertension is the most important risk factor for cardiovascular mortality. However, few previous studies have examined the relationship between gaseous air pollution and morbidity for hypertension. METHODS Daily data on emergency hospital visits (EH...

There is limited evidence that long-term exposure to ambient air pollution increases the risk of childhood autism spectrum disorder (ASD). The objective of the study was to investigate the associations between long-term exposure to air pollution and newly diagnostic ASD in Taiwan. We conducted a population-based cohort of 49,073 children age less than 3 years in 2000 that were retrieved from Ta...

Background Ambient air pollution has a negative effect on many diseases, such as cardiovascular and respiratory diseases. Recent studies have reported a relationship between air pollution and renal function, but the results were limited to exposure to particulate matter (PM). This study was to identify associations between various air pollutants and renal function among Korean adults. Methods...

BACKGROUND Pooled estimates of air pollution health effects are important drivers of environmental risk communications and political willingness. In China, there is a lack of review studies to provide such estimates for health impact assessments. METHODS We systematically searched the MEDLINE database using keywords of 80 major Chinese cities in Mainland China, Hong Kong and Taiwan on 30 June...

This study investigated the seasonal variation of ambient air quality status of Burdwan town using GIS approach. Concentration of SO2 (sulphur dioxide), NO2 (nitrogen dioxide) and RSPM (respiratory suspended particulate matter) were measured once a week for 24 hour in both premonsoon and postmonsoon season. The seasonal average concentration of the RSPM, SO2 and NO2 in premonsoon season was obs...

Nitrogen dioxide (NO2) is a common indoor and outdoor air pollutant that may induce deterioration of respiratory health. In this study the effects of repeated daily exposure to NO2 on airway antioxidant status, inflammatory cell and mediator responses, and lung function were examined. Healthy nonsmoking subjects were exposed under controlled conditions to air (once) and to 2 ppm of NO2 for 4 h ...

The 40th anniversary of the manufacture of the world’s fi rst commercial batch of autocatalysts for passenger cars at Johnson Matthey Plc’s site in Royston, UK, was marked in May 2014. Despite the enormous progress made in reducing the emission of pollutants from vehicles since the 1970s, there has also been considerable recent discussion about the levels of nitrogen oxides (NOx), especially ni...

BACKGROUND Power plant workers are potentially exposed to nitrogen dioxide (NO2) and may therefore be at higher risk of pulmonary diseases than the general population. AIMS To assess the association of NO2 exposure with spirometric abnormalities in power plant workers. METHODS Forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) and forced expiratory ratio (FER = FEV1/FVC) we...

London’s air quality is the worst in the UK. Levels of pollution cause serious health impacts, which have led to UK and EU air quality targets. A considerable proportion of London will not meet these targets, particularly for nitrogen dioxide (NO2) and particulate matter (PM10). To achieve the air quality targets, significant additional action is needed, particularly to reduce road transport em...

Land use regression (LUR) models have been globally used to estimate long-term air pollution exposures. The present study aimed to analyze the association of different land use types and traffic measures with air pollutants in Tehran, Iran, as part of the future development of LUR models. Data of the particulate matter (PM10), sulfur dioxide (SO2), and nitrogen dioxide (NO2) were extracted from...
