London fog obviously revealed the role of air pollution in increasing mortality and morbidity rates associated with this phenomenon but several studies in the 70’s and 80’s couldn’t establish sufficient link between air pollution and death. In the 1990’s, time series studies conducted in a different locations, showed that air pollution levels, even at lower concentrations, were associated with ...

Exposure to high levels of air pollution can cause a variety of adverse health outcomes. Air quality in developed countries has been generally improved over the last three decades. However, many recent epidemiological studies have consistently shown positive associations between low-level exposure to air pollution and health outcomes. Thus, adverse health effects of air pollution, even at relat...

BACKGROUND This study examined potential associations between exposure to episodes of air pollution and alterations in semen quality. The air pollution, resulting from combustion of coal for industry and home heating in the Teplice district of the Czech Republic, was much higher during the winter than at other times of year with peaks exceeding US air quality standards. METHODS Young men from...
