China to build network to monitor smog impact on health
雾霾已影响6亿人 16个省(直辖市)今年开展监测 包括人口、死因等资料收集。记者昨天从中国疾病预防控制中心获悉，中国将用3到5年的时间建立覆盖全国的空气污染(雾霾)健康影响监测网络，掌握空气污染暴露水平及人群健康影响变化趋势。
China will build a nation-wide network within three to five years to monitor the impact of air pollution on health, a latest step to deal with a persistent 1 smog crisis in big cities, an official said.
A total of 43 monitoring spots will be set up in 16 provinces and municipalities frequently engulfed 2 by smog so as to facilitate research on air pollutants 3 in different regions, the impact on the health of vulnerable groups and the study of related diseases, said Xu Dongqun, an official with the Chinese Center for Disease Control and Prevention.
With funds allocated 4 by the central government, the study will provide reference for preventive efforts to reduce the PM 2.5, Xu said.
Thick and hazardous 5 smog have hit 17 provinces and municipalities with a population of 600 million this year. One of the major cities is Beijing, which has been shrouded 6 in smog for several days during the ongoing 7 seven-day national holiday.
China recently issued a 1.75 trillion-yuan (284.2 billion U.S. dollars) plan to tackle the worsening air, pledging to improve air quality within five years in order to decrease the number of heavily polluted days and improve the air in major city clusters. （北京青年报）

中国疾控中心表示，今后将通过3-5年的时间，建立覆盖全国的空气污染(雾霾)健康影响监测网络，掌握空气污染暴露水平及人群健康影响变化趋势，为采取有针对性的预防对策和干预措施提供依据。2013年开展空气污染(雾霾)特征污染物及人群健康影响监测，掌握不同地区PM2.5污染特征及成分差异，了解不同地区空气污染健康影响状况。
据介绍，具体监测方法是，今年选择雾霾高发的16个省(直辖市)43个监测点，开展雾霾健康影响监测工作，包括全市层面环保、气象、人口、死因等资料收集；以社区为基础的雾霾特征污染物及成分监测、敏感人群健康监测和人群健康风险评估危险因素及人群活动模式监测；以医院为基础的疾病监测。
中国疾控中心要求，在出现雾霾天气时，各个监测点需进行PM2.5加密采样，了解雾霾与非雾霾天气下PM2.5质量浓度与成分的变化，加强收集雾霾期间死因监测数据、医院门急诊数据、气象监测数据、空气污染监测数据等。专家还鼓励各监测点根据自身情况开展有关健康影响监测资料收集工作，如小学生缺课信息、小学生体检信息等，以便待条件成熟时适时纳入项目监测工作。
我国环境与健康研究专家发现，在雾霾天气的时候，儿童、老年人、呼吸系统和心脑血管疾病等易感人群的患病率增加。从120急救中心的数据中他们发现，急救车出诊的次数明显增加。一些医院的数据也显示出，心血管疾病和呼吸系统疾病就诊人数也都有所增加。
