我们于1982年在保定市进行了大气污染状况与肺癌死亡调查。 调查发现:市中心区的高人口密度和高肺癌死亡水平,启示我们寻找肺癌死亡水平和人口密度之间的关系。按不同派出所(每派出所2-3万人)计算的肺癌死亡率,最高为13.26/10万,最低为3.04/10万。人口密谋最高为35,149人/Km~3;最低为6,885人/Km~2(表、图)。人口密度和肺癌死亡水 We conducted a survey of air pollution status and lung cancer deaths in Baoding in 1982. The survey found that the high population density and high level of death from lung cancer in downtown area enlightened us to look for the relationship between lung cancer death level and population density. According to different police stations (each police station 2-3 million people) to calculate the lung cancer death rate, the highest is 13.26 / 100000, the lowest is 3.04 / 100000. The highest population density is 35,149 persons / Km 3; the lowest is 6,885 persons / Km 2 (Table, figure). Population density and lung cancer death water
