二氧化硫(SO_2)是最重要的空气污染物之一.它对人类健康的影响,已引起普遍的关注.据流行病学的观察提示,空气中SO_2浓度升高与呼吸道感染发病率增加有关.气管炎病人的急性发作与空气中SO_2浓度的升高有关.本文旨在进一步研究SO_2对呼吸道及全身性免疫功能的影响,以探讨SO_2污染空气引起呼吸道疾病的机理.
Sulfur dioxide (SO 2 ) is one of the most important air pollutants. Its impact on human health has attracted widespread attention. According to epidemiological observations, elevated airborne SO 2 concentrations are associated with increased incidence of respiratory infections. The acute exacerbation of inflammatory patients is related to the increase of SO2 concentration in the air. This paper aims to further study the effect of SO2 on respiratory and systemic immune function to explore the mechanism of airborne respiratory diseases caused by SO2 pollution.
