大气污染对人体健康的影响已受到国内外重视,我们在1974～1976年对北京污染严重的石景山地区广宁村进行了大气污染对居民健康影响的调查研究,该地区的居民主要受电厂排出物的影响,其飘尘、SO_2浓度都明显高于对照区,飘尘、SO_2三年平均浓度分别为0.6mg/m~3和0.143mg/m~3。在冬天逆温时,因三面环山,大气污染物不易扩散,飘尘、SO_2浓度分别高达1.86mg/m~3和0.5mg/m~3,长期生活在该区居民的呼吸道疾病发病率也较高,肺功能明显下降,气道阻力高于对照区一倍。
The impact of air pollution on human health has drawn great attention both at home and abroad. From 1974 to 1976, we investigated the health effects of air pollution on residents in Guangning Village, a heavily polluted area in Beijing. Residents in the area were mainly affected by plant effluents , The fly ash and SO 2 concentrations were significantly higher than the control area, and the three-year average concentrations of SO 2 and fly ash were 0.6 mg / m 3 and 0.143 mg / m 3, respectively. In the winter when the inversion temperature, due to the three sides of the mountain, the air pollutants are not easy to spread, floating dust, SO_2 concentrations were as high as 1.86mg / m ~ 3 and 0.5mg / m ~ 3, long-term residents living in the area of respiratory disease incidence High, pulmonary function decreased significantly, airway resistance than the control area doubled.
