BACKGROUND Atrial fibrillation is the most common sustained arrhythmia and is associated with cardiovascular morbidity and mortality. The few studies conducted on short-term effects of air pollution on episodes of atrial fibrillation indicate a positive association, though not consistently. OBJECTIVES The aim of this study was to evaluate the long-term impact of traffic-related air pollution ...
BACKGROUND While a great number of papers have been published on the short-term effects of air pollution on mortality, few have tried to assess whether this association varies according to the neighbourhood socioeconomic level and long-term ambient air concentrations measured at the place of residence. We explored the effect modification of 1) socioeconomic status, 2) long-term NO2 ambient air ...
The present work aims at a detailed study and explanation of the pollution transport in the air basin over South-westem Bulgaria and Northem Greece and assessment of the air pollution exchange between Bulgaria and Greece. Some weli known specific climatic air poilution effects were studied and explained. Calculations were made ofthe S02 poilution ofthe Balkan peninsula from both Greek and Buiga...
A diary study on a random sample of 625 Swiss children aged 0 to 5 yr was conducted in two cities in Switzerland to investigate the association between air pollution and respiratory symptoms. Total suspended particulates (TSP), SO2 and NO2 were measured by city monitor. In addition, passive samplers inside and outside the home measured NO2 concentration during the 6 wk each child was on the dia...
Indoor air pollution, specifically restricted in its meaning to chemicals in home indoor air environment, presents a new and probably an important challenge to the researchers of the air pollution field. The general overview of this topic suggests that the voluminous data generated in the past ten or so years have only defined the rudiments of the problem, and significant areas of research stil...
Air pollution measurements are aimed at improving our understanding of the chemical properties of the atmosphere, addressing mainly three issues with very different space and time scales: • Measurement of critical or peak values of air pollutant in densely urbanized/industrialized sites. • Long term observation and trend analysis on air quality. • Evaluation of photochemical pollution (smog) ep...
Reviews of daily time-series mortality studies from many cities throughout the world suggest that daily mortality counts are associated with short-term changes in particulate matter (PM) air pollution. One U.S. city, however, with conspicuously weak PM-mortality associations was Salt Lake City, Utah; however, relatively robust PM-mortality associations have been observed in a neighboring metrop...
Air pollution is usually driven by a complex combination of factors in which meteorology, physical obstacles, and interactions between pollutants play significant roles. Considering the characteristics of urban atmospheric pollution and its consequent impacts on human health and quality of life, forecasting models have emerged as an effective tool to identify and forecast air pollution episodes...
