【摘要】 通过研究PM_2.5对中国大陆地区7种传染病发病率的影响,得到了百日咳、猩红热、麻疹、肺结核、风疹、流行性腮腺炎及流行性感冒的PM_2.5归因发病率分布和变化趋势.结果表明,这7类传染病的PM_2.5归因发病率主要集中于中国大陆中部和东部地区;除流感、猩红热及少数省份的百日咳外,其余传染病的PM_2.5归因发病率均呈不同程度的降低.当部分省市的ρ(PM_2.5)降至世界卫生组织提出的安全值10μg/m³时,北京、天津及上海等人口稠密,ρ(PM_2.5)高值区的PM_2.5归因发病率降低程度最大.更多还原

【Abstract】 Many studies have revealed the non-negligible hazard of PM_2.5 to human health. By investigating the impact of PM_2.5 on morbidities of infectious diseases in China’s mainland, the PM_2.5 attributed morbidities of infectious diseases, as well as its variation trend were calculated regarding seven kinds of infectious diseases such as pertussis, scarlatina, measles, tuberculosis, rubella, mumps and influenza. The results showed that the PM_2.5 attributed morbidities of the 7 infectious diseases mainly concentrated in middle and eastern of China’s mainland. The PM_2.5 attributed morbidities of infectious diseases presented various declining trends except for the influenza, scarlatina and pertussis in a few regions. When the ρ(PM_2.5) was under a safe value of the concentrations（10 μg/m³） proposed by world health organization,it was shown that in regions of dense population and high ρ(PM_2.5) like Beijing, Tianjin, Shanghai, etc.,there would be a most significant reduction of the PM_2.5 attributed morbidities.更多还原
