INFLAMMATORY BOWEL DISEASES AND AIR POLLUTION (Abstract). Air pollution is responsible for the increase in mortality, morbidity and a high number of hospitalizations for respir atory and cardio-vascular diseases. Recently, several studies have shown that air pollution can also affect the digestive system. The major impact was observed on inflammatory bowel diseases (Crohn’s disease and ulcerati...

INTRODUCTION Household air pollution from solid fuel burning kills over 4 million people every year including half a million children from acute lower respiratory infections. Although biologically plausible, it is not clear whether household air pollution is also associated with acute lower respiratory infections in adults. We systematically reviewed the literature on household air pollution an...

The effect of air pollution on chronic respiratory diseases (CRD) was examined in a study in the New York metropolitan area in 1972. Four study communities, sites A, B, C and D, were selected for the similarity of socioeconomic and demographic characteristics. Historically, these communities represented an increasing gradient of air pollution levels. However, after air quality improvement in th...

Air pollution has been linked to several malignancies, including lung cancer, urinary bladder cancer, and acute leukaemia; the evidence is most abundant for lung cancer, for which several causal factors are well established (Samet and Cohen, 2006). Worldwide, tobacco use, and in particular cigarette smoking, is the dominant cause of lung cancer and accounts for the majority of cases; in fact, m...

Air pollution in Japan caused respiratory disease, such as chronic bronchitis and asthma, in many individuals in the 1960s. Although air pollution has decreased, many victims of air pollution-related respiratory disease are limited in their activities of daily living because of respiratory symptoms. The purpose of this study was to evaluate the efficacy of pulmonary rehabilitation in victims of...

Air pollution issues in South Africa were only brought to public attention in the late 1980’s when concern was expressed over the high emissions from industries on the Highveld (east of Johannesburg). Air pollution issues have since been raised in other parts of the country such as Durban and Cape Town. Although the research and monitoring of air pollution has been largely fragmented and uncoor...
