广州市大气污染与恶性肿瘤发病率关系的探讨

Study on the Relationship between Air Pollution and Cancer Mortality in Guangzhou City

对广州市恶性肿瘤发病率和大气污染综合指数进行相关性分析.结果表明:肺癌发病率与前5年大气污染综合指数的相关系数较之与历年大气污染综合指数更具显著性意义,所建立的回归方程亦较以前者效果好,实测值与预测值更相符.提示大气污染可能是肺癌发病因素之一,而且其效应是长期的.

The relationship between air pollution composite index and Cancer mortality in Guangzhou city has been analysed relatively.The results shows:the relative coefficient between lung canler mortality and air pollution composite index in five years before is more evident than the relative coefficient between lang cancer mortality and air pollution composite index now.The effece of regressive equa- tion established is better than this later,and the conformity of between actual number and predicted number is also better than this later.The results indicates that air pollution maybe one of the factor causing lung cancer,and the air poll- ution health effect is long.
