Respiratory health effects were investigated with hospital visits for asthma or COPD. From January 2006 to April 2012, data of air quality and weather conditions from the Meteorological Administration, and hospital visits from National Health Insurance Corporation were analyzed.ResultsDuring the evaluation, yellow dust was 52 days, haze 167 days, mist 176 days, fog 51 days. Concentrations of PM10 were higher on days with all weather conditions. NO2 was lower in yellow dust days, and CO, NO2 SO2 were higher in the haze and mist. In fog days, there was no difference for air quality, except PM10.Relative risk for hospital visits with asthma was 1.22 in 5 day after yellow dust weather, COPD was 1.38. In 1 day after mist weather, relative risk for hospital visits with asthma was 1.04, COPD was 1.12.ConclusionsWeather conditions (yellow dust, haze, mist, and fog) consist of different air quality, and it affect for hospital visits for asthma or COPD after few days.
