Atrial fibrillation is the most common sustained arrhythmia and associated with cardiovascular morbidity and mortality. The few studies conducted on short-term effects of air pollution on episodes of atrial fibrillation indicates a positive association, though not consistently.

European air quality legislation has reduced emissions of air pollutants across Europe since the 1970s, affecting air quality, human health and regional climate. We used a coupled composition-climate model to simulate the impacts of European air quality legislation and technology measures implemented between 1970 and 2010.

Telomere length and mitochondrial DNA (mtDNA) content are markers of aging and aging-related diseases. There is inconclusive evidence concerning the mechanistic effects of airborne particulate matter (PM) exposure on biomolecular markers of ageing. The present study examines the association between short- and long-term PM exposure with telomere length and mtDNA content in elderly and investigates to what extend this association is mediated by expression of genes playing a role in the telomere-mitochondrial axis of aging.

Come winter, and the air quality in northern India begins to deteriorate.The smoke resulting from burning crop residues combined with vehicular emissions make the air we breathe deadly.

Come winter, and the air quality in northern India begins to deteriorate. A thick blanket of smog (mixture of smoke and fog) engulfs the National Capital Region which reduces visibility and gives a tough time to commuters.

Air pollution in cities is emerging as the major reason behind the rise in eye allergies and conjunctivitis in people of all ages, doctors say.

Air contaminated with pollutants such as ozone and tiny particles could cause the premature death of about 6.6 million people a year by 2050 if nothing is done to improve air quality, warns this study published in the journal Nature

The main objective of the air quality index (AQI) system is to interpret air quality in a standardized indicator to enable the public to understand the likely health and environmental impacts of air pollutant concentration levels monitored on any given day. The daily averaged concentration data of air pollutants of monitoring sites under the National Ambient Air Quality Monitoring Programme of Delhi were analysed for the period 2001–2010 using the AQI system.

The relationship between air borne particulate matter ≤10 μm (PM10) exposure and pregnancy-induced hypertension (PIH) is inconclusive. Few studies have been conducted, and fewer were conducted in areas with high levels of PM10.

The Kathmandu Valley in South Asia is considered as one of the global "hot spots" in terms of urban air pollution. It is facing severe air quality problems as a result of rapid urbanization and land use change, socioeconomic transformation and high population growth.
