| Abstract | Romania differs from Western Europe and North America in the nature of its air pollution and the health status. The aim of the study was to investigate the effects of short-term exposure to air pollution on hospital admissions for respiratory diseases and its modification by climate parameters. The study population comprised 100.000 inhabitants of the city Drobeta Turnu Severin, Romania. The air pollution data consist of total suspended particles (TSP), sulfur dioxide (SO2) and nitrogen dioxide (NO2). The meteorological data comprise daily air temperature and relative air humidity. Daily hospital admissions of male and female patients due to asthma, chronic bronchitis and chronic obstructive pulmonary disease were recorded during the study period of 586 days. As statistical technique we applied generalized additive models. Delayed effects up to seven days were analyzed in single lag and Poisson distributed lag models (PDLMs). For comparability with other existing results, we applied the recommendations of the APHEA-2 protocols: firstly a core model without pollutants was built and in a second step the core model was extended by air pollutants. A threshold analysis was done for all significant effects by computing the effect of only values being greater than the threshold value. We investigated the modifying effect of humidity for all observed significant adverse factors including an interaction term in the model. We found an increase in hospital admissions for chronic bronchitis for an increase of 10μg/m³ TSP. An increase in absolute humidity reduces the adverse health effect of TSP on hospital admissions of chronic bronchitis. We observed a significant increase in hospital admissions because of chronic bronchitis for an increment of 1 μg/m³ SO2. In a multi pollutant model, including all significant single pollutant effects, the effect of SO2 remains significant, while the effect of TSP is weakly significant. This study confirms that the important influences of TSP and SO2 on respiratory morbidity can be verified in Romania with another composition of air pollution, too. It also indicates that the adverse effect of TSP is reduced with higher air humidity and aggravated with dry air. |
