采用生态学研究和时间序列研究两种方法，分析了沈阳市大气污染对总死亡率及各种急、慢性病因的影响（用１９９２年死亡资料），在按市环保历年监测数据分成高、中、低３个污染区后，３区间差异有显著性者为总死亡率、慢性阻塞性肺疾患（ＣＯＰＤ）、心脑血管病、总癌和结核。时间序列研究全市每天死亡率与死前３天平均污染水平（ＴＳＰ和ＳＯ２），在调控当天气温和气湿后，分析污染与死亡的相关。得知：与污染水平相关有显著性者有总死亡率、ＣＯＰＤ、心脑血管病。ＴＳＰ每增加１００μｇ／ｍ３，三类死因各增加２％、３％、２％；ＳＯ２每增加１００μｇ／ｍ３，三类死因各增加２％、７％、２％。ＣＯＰＤ和ＳＯ２相关更密切，而心脑血管病与ＴＳＰ相关更密切。提示大气污染物除造成居民健康慢性损害外，还有加剧此等慢性病人病情，加速死亡的作用。
Using the two methods of ecological research and time series study, the impact of air pollution on total mortality rate and various causes of acute and chronic diseases in Shenyang City was analyzed (using the death data of 1992). According to the monitoring data of municipal environmental protection over the years, the data were divided into high and medium , Three low pollution area, the three intervals were significantly different from the total mortality, chronic obstructive pulmonary disease (COPD), cardiovascular and cerebrovascular disease, total cancer and tuberculosis. Time series study of the city’s daily mortality and the average level of pollution three days before death (TSP and SO2), in the control of the weather when the temperature and humidity, the analysis of pollution and death related. That: a significant correlation with the level of pollution were total mortality, COPD, cardiovascular and cerebrovascular disease. Each increase of TSP by 100 μg / m3 resulted in an increase of 2%, 3% and 2% for each of the three types of cause of death, and a 2%, 7% and 2% increase in each of the three causes for each increase of 100 μg / m3 of SO2. COPD and SO2 are more closely related, while cardiovascular and cerebrovascular diseases are more closely related to TSP. It is suggested that air pollutants not only cause chronic health damage of residents, but also exacerbate the condition of these chronic patients and accelerate the death.
