【摘要】 当前我国空气中PM2.5污染形势严峻。2013年,在全国纳入监测范围的74座城市中,接近92%的城市的空气PM2.5年均浓度达不到国家标准,其中京津冀、长三角和珠三角等重点区域PM2.5污染尤为严重。PM2.5中含有多种有毒有害物质,会直接危害公众的身体健康。已有研究显示,PM2.5污染PM2.5污染会直接影响人体的呼吸系统、影响人体的心血管系统,与肺癌的发生率和死亡率密切相关。未来还需从PM2.5毒理学及暴露-反应关系等影响机制方面做深入研究。我国当前治理PM2.5污染的难点和出路在哪里?科学评价PM2.5污染对我国不同人群疾病发生的负担率等应是我们认真思考的问题。更多还原

【Abstract】 There is a serious situation for PM2.5 pollution in China at present. Among 74 cities starting PM2.5 monitoring in 2013, about 92% cities, in which the PM2.5 concentration exceeds the state standard limit value. The most polluted areas in China are Beijing-Tianjin-Hebei region, Yangtze River Delta region and the Pearl River Delta region. Some poisonous species containing in PM2.5 may have a direct influence on the human health. Some research results indicate that diseases such as respiratory system, cardiovascular system are evidently affected by PM2.5 pollution. Moreover, PM2.5 concentration is directly related to lung cancer, but some key problems, like PM2.5 toxicology, exposure--response relationship and etc should be deep-going studied.更多还原
