This study is to distinguish the objective and subjective measures of atmospheric visibility, and investigate the relationship between the two measures as well as the effect on the people's behavioral intentions on air pollution in China. A mixed method was adopted in this study combining both lab experiments to measure objective atmospheric visibility and a questionnaire survey to measure subj...

Sensory responses to clean air and air polluted by five building materials under different combinations of temperature and humidity in the ranges 18-28æC and 30-70%RH were studied in the laboratory. A specially designed test system was built and a set of experiments was designed to observe separately the impact of temperature and humidity on the perception of air quality/odour intensity, and on...

Air pollution is one of the most important problems in urban areas that always threaten citizen's health. Photochemical smog is one of the main factors of air pollution in large cities like Tehran. Usually smog is not only a part of nature, but is being analyzed as an independent matter, which highly affects on the nature. It has been used as relationship between atmospheric elements such as te...

The 10-year mortality in a sample of adult inhabitants of Cracow, Poland, was analysed according to the levels of air pollution in the area of residence. Smoking habit and several social and occupational factors were considered in the analysis, which was carried out with the use of a multivariate method for categorical variables. Among men the main effect of air pollution was marginally signifi...

Purpose: This study is the first to examine the effect of extreme weather on mortality in Cyprus. It aims to investigate the individual effect of meteorological indicators on mortality, as well as the role of air pollution as a potential confounder of heat related health effects. Methods: The analysis concentrated on the warm periods (April to September) of the years 2007-2009. A Generalized Li...

Epidemiologic studies have demonstrated a consistent link between sudden cardiac deaths and particulate air pollution. We used implanted cardioverter defibrillator (ICD) records of ventricular tachyarrhythmias to assess the role of air pollution as a trigger of these potentially life-threatening events. The study cohort consisted of 203 cardiac patients with ICD devices in the Boston metropolit...
