西安PM2.5指数爆表 燃放烟花爆竹成祸首|PM2.5|燃放烟花|西安PM2.5_新闻资讯

　　中新网西安1月31日电 (记者 张一辰)爆竹声声辞旧岁，从除夕到大年初一，西安及周边城区却依旧被雾霾天气笼罩。截至31日9时，该市13个监测点的PM2.5数值已亮起“红灯”。

　　据中国环境监测总站统计，截至31日上午9时，西安市13个监测点中的PM2.5数值均突破300微克/立方米属严重污染。其中，临潼区监测点PM2.5数值为986微克/立方米，高新西区监测点亦达714微克/立方米令人乍舌。

　　西安市供销合作社联合社经济发展处的工作人员表示，马年春节前夕，西安市的鞭炮销售量较往年降低，城区烟花爆竹零售经营点由500个缩减到300个，其中，一些烟花爆竹零售点的销售量比去年下降近三成。

　　31日上午，记者在西安市中心采访时发现，数百米外之外的南门、城墙影影绰绰，无法辨识，空气中弥漫着燃放烟花爆竹后刺鼻的火药味。

　　据中国中央气象台预报，1月31日，中国的华北南部、陕西关中、黄淮中部、四川盆地、长江中下游地区、新疆北部等地的部分地区气象条件不适宜燃放烟花爆竹。

　　2011年11月1日，中国内地开始实施《环境空气PM10和PM2.5的测定重量法》。据称，这是中国首次对细颗粒物PM2.5的测定进行规范。2012年2月，中国国务院发布了新修订的环境空气质量标准，首次增加了对PM2.5的监测。随后，各地开始对PM2.5进行监测。

　　燃放鞭炮作为内地民众过春节的一项传统习俗，寓意“辞旧迎新”，寄托对来年的美好祝愿。而近年来，随着经济发展跟生态环境保护之间矛盾的日益凸显，在内地各大城市“禁放”与“准放”成为社会争议的焦点。

　　家住西安曲江新区的徐子科告诉记者，春节团聚是一家人一年中的最重要的事情，中国人过节讲究热闹，为此，鞭炮和烟花他早已准备好，在大年夜听鞭炮响、看烟花亮是他们一家人的春节“传统”。

　　专家认为，造成空气污染的因素繁多，在气象条件适宜的情况下燃放烟花爆竹，其“瞬间”的污染力足以破坏空气质量。随着时代的变化民俗也不断变迁，逛文化庙会、猜灯谜、写对联、包饺子，都是传统年味的体现，过年而并非只有炮声隆隆。(完)
