line-height: 25px; font-family: "MS Song", "MS Hei"; padding: 0px 40px 12px 0px;">(德国之声中文网) 根据中国媒体，北京最近陷入灰色雾霾，8月和9月所见的晴朗天空不再。北京环境监测中心在微博上发布声明表示，雾霾在周一（10/15）因为扩散条件不利而达到高峰，之后随着北方冷锋到来将可望改善。</p><p style="font-size: 17px; line-height: 25px; font-family: "MS Song", "MS Hei"; padding: 0px 40px 12px 0px;">清华大学环境学院教授王书肖表示：“北京市的人为源当中，排序上移动源排第一位，第二是扬尘，然后是工业源、生活源和燃煤源。”</p><p style="font-size: 17px; line-height: 25px; font-family: "MS Song", "MS Hei"; padding: 0px 40px 12px 0px;">过去当局通常会将灰蒙蒙的天空归咎于大型钢铁工厂燃煤造成污染，去年冬天还曾全面禁止京津冀地区的工业生产，但上个月中国生态与环境部表示，只要达到排放标准，钢铁厂就会继续生产。而根据《北京科技报》刊出北京市环境保护局在5月发布的一份报告，“生活源污染” 占了北京空污总量的12％，和工业污染源相当。</p><p style="font-size: 17px; line-height: 25px; font-family: "MS Song", "MS Hei"; padding: 0px 40px 12px 0px;">报导中访问北京市环境科学研究院副院长石爱军，他说：“生活源污染排放主要来源于市民的‘吃、穿、住、行’等日常生活，并且生活源排放是刚性的。比如，所有有香味的日用消费品都含有挥发性有机物，特别是香水、发胶、空气清新剂、杀虫剂、清洗剂等气雾剂，日用消费品中的挥发性有机物含量都较高。”石爱军也表示，食物加工制作过程中也会排放PM2.5和挥发性有机物等大气污染物。主要来源包括餐饮、单位食堂、居民家庭厨房。</p><p style="font-size: 17px; line-height: 25px; font-family: "MS Song", "MS Hei"; padding: 0px 40px 12px 0px;">相关报导在中国引起讨论，许多人对于香水和发胶也会引起空污感到不可置信。根据《中国新闻网》，北京PM2.5源解析专家组的专家出面辟谣。专家表示，生活源当中的确包含香水，但是说是香水引起了北京大气污染，这不够全面准确。</p><p style="font-size: 17px; line-height: 25px; font-family: "MS Song", "MS Hei"; padding: 0px 40px 12px 0px;">北京市环保监测中心则说：“北京本地的生活源的贡献大头还是餐饮业等污染源的排放，像大家常用的香水、发胶等日用消费品等，仅属于生活溶剂的一小部分，其对大气环境的影响确实存在，但影响不大。”</p><div style="float: right;
