Firecrackers less, don’t let the "flavor" with "haze" original title: Firecrackers less, don’t let the "flavor" with "haze" – editorial world this is not immutable and frozen "year flavour", the traditional may not necessarily be strict in demands to follow. The new year’s Eve as little as possible or not to set off firecrackers, on the first day of the new year, in the fresh air, and pay New Year’s call Tachun travel, not better? The traditional Chinese years are just out of the pot of dumplings, glutinous rice cake, soft fine candy, snacks and children’s clothes, of course, ultimately, the crackling sound of firecrackers. However, with the enhancement of people’s awareness of environmental protection, the increasing pressure of urban pollution control, firecrackers, the Spring Festival "standard" is also more and more "no joy". According to reports, the meteorological department is expected this year, new year’s Eve day Beijing air quality to maintain a good level, at night under concentrated fireworks, at short time can reach the level of severe pollution, the city’s new year’s day overall in the four levels of pollution. The sound of firecrackers really brings the "year flavor" to everyone, but it also brings "haze" flavor". How to choose between traditional folk customs and clean air is not only the topic of concern for the media during the Spring Festival, but also the problem faced by every ordinary family. In recent years, frequent Urban Haze crisis, so that the local government more environmental needs into the scope of consideration. According to statistics from the beginning of 2015, now nearly 700, the city banned firecrackers. 138 of the city to ban fireworks, introduced the policy of 536 City, fireworks ban or limit discharge has become a major trend. How many PM2.5 will contribute to setting off firecrackers? It is difficult for ordinary citizens to have an intuitive understanding of it. According to the experimental results of a Shanghai Jiao Tong University in early 2015 showed that 3 small firecrackers in the test chamber of 30 cubic meters in the discharge, the concentration of PM2.5 produced was 1230 micrograms per cubic meter, 2.46 times the data burst table value of 500 micrograms per cubic meter, means that each set off firecrackers produced PM2.5 quality is 12300 micrograms. Recently, a Shandong media joint Ji’nan Municipal Environmental Monitoring Center Station confirmed to do experiments, a hanging 2000 firecrackers after release, PM2.5 increased by more than 100 times before setting off. In addition, firecrackers are usually based on potassium nitrate, sulfur and charcoal as raw materials, there will be a lot of nitrogen oxides, sulfur dioxide, hydrogen sulfide and carbon monoxide produced after discharge. And looks gorgeous, pleasing fireworks, may also produce heavy metal pollution, the direct harm to the human body need not say. If the new year’s Eve firecrackers during the Spring Festival has become the standard, then the new year’s day morning overcast days, the nose of the air and the ubiquity of noise and garbage firecrackers will become the Spring Festival "standard". But you can see that with the increase of the general public environmental appeals, ban or limit the fireworks are increasingly accepted by the general public. And the city managers, also promote the less or no firecrackers, become the new year’s new normal". For example, the sales time of fireworks in Beijing has been shortened from 20 days to 10 days, and sales points have been reduced by 4 for many years

少放鞭炮,别让“年味”染“霾味”   原标题:少放鞭炮,别让“年味”染“霾味”   ■ 社论   世上本没有一成不变的“年味”,传统也并非一定要一丝不苟地遵循。除夕尽量少放或者不放鞭炮,在新年的第一天,迎着清新的空气拜年访友、踏春出游,不是更好吗?   传统的中国年里,有刚出锅的饺子、软糯的年糕、精美的糖果、小吃以及小孩子身上的新衣,当然,也少不了噼啪作响的鞭炮。然而,随着人们环保意识的增强,城市治污压力的增大,鞭炮,这一春节“标配”也越来越不“讨喜”了。   据报道,气象部门预计,今年除夕白天京城空气质量保持良好水平,入夜后受集中燃放烟花爆竹影响,凌晨短时可达重度污染水平,大年初一全市整体处于四级中度污染。爆竹声声确实给大家带来了“年味”,但随之也会带来“霾味”。传统民俗与干净空气之间如何选择,不仅是每年春节期间媒体关心的议题,也是每个普通家庭面临的问题。   而近年来频频侵扰城市的雾霾危机,让地方政府更多地将环保需求纳入了考量范围。据2015年初的统计数据,现在已有近700城市禁放、限放鞭炮。其中有138个城市禁放烟花爆竹,出台限放政策的城市536个,烟花爆竹禁放或者限放已成为大趋势。   燃放鞭炮到底会“贡献”多少PM2.5,普通市民对此难有直观的认识。根据上海交通大学在2015年初的一项实验结果表明,3只小鞭炮在30立方米的测试舱中燃放,产生的PM2.5浓度为1230微克 立方米,该数据为爆表值500微克 立方米的2.46倍,意味着每只鞭炮燃放产生的PM2.5质量为12300微克。而近日山东某媒体联合济南市环境监测中心站做的实验证实,一挂2000响的鞭炮放完后,PM2.5比燃放前上升了100多倍。   再加上,鞭炮通常是以硝酸钾、硫黄、木炭等为原料,燃放后会有大量氮氧化物、二氧化硫、硫化氢、一氧化碳等产生。而看起来色彩艳丽、赏心悦目的烟花,也可能会产生重金属污染,对人体造成的直接危害自不必说。   如果除夕放鞭炮成为春节的“标配”,那么大年初一早上灰蒙蒙的天、呛鼻的空气以及无处不在的噪音和鞭炮垃圾也会成为春节的“标配”。但可以看到的是,随着普通市民环保诉求的增强,禁放或者限放烟花爆竹也越来越被普通市民所接受。而城市的管理者,也在推动着少放或者不放鞭炮成为过年的“新常态”。   比如,今年北京烟花爆竹的销售时间已从过去的20天缩短至10天,销售点也连续多年减少。今年全市准许的零售点719家,比去年减少200余家,下降23.7%;其中五环内的零售点仅有222家,比去年少102家。北京市安监局相关负责人表示,明年春节,中心城区很有可能不再设置花炮零售点。   烟花爆竹,本来是古人用来驱鬼避邪之用。在岁月更迭中,其避邪的本义逐渐被消解,烘托喜庆气氛逐渐成为主要功能,也被看做传统“年味”的象征。但世上本没有一成不变的“年味”,传统也并非一定要一丝不苟地遵循。对更多普通人来讲,回家与亲人团聚,一起许下对新一年的愿望,才是节日的意义。除夕尽量少放或者不放鞭炮,在新年的第一天,迎着清新的空气拜年访友、踏春出游,不是更好吗? 责任编辑:黄睿 SN224相关的主题文章:
