Beijing's environmental protection Bureau published the top ten rumor: wind energy, uranium, coal "lie down"
United States weather extremes due to pollution in China, mobile phone base station, the more radiation more stole Beijing, Inner Mongolia wind power Gale caused smog, 9 to 11, is dust layers air dirty ... ... In everyday life, you always hear these rumors? On June 1, the Green spread Congress Beijing municipal environmental protection Bureau, publish and rumor rumors ten environmental protection.
According to the Beijing municipal environmental protection Bureau official, rumor is a network filter, ten environmental protection specialists, due to its higher transmission rates were elected. In today's environment has received widespread attention, rumors of environmental protection lack scientific and factual support, facts and confuse, caused great harm to the public and society, is not conducive to science of environmental protection work and the dissemination of the concept of ecological civilization. Remove green rumors the activities carried out, aimed at spreading environmental scientific knowledge, improve the scientific literacy of the public and for the construction of ecological civilization in the capital to create a good public opinion atmosphere. This top ten rumours of environmental protection:
Rumor: stole the winds cause smog in Beijing, Inner Mongolia wind power?
Media reports, building massive wind farms in Inner Mongolia and stole Beijing strong winds, resulting in haze. Is this for real?
The truth: wind flow around obstacles can be recovered, local wind power or local shelter does not affect distance downstream of the wind, the fog, haze formation of root cause or because of surface pollutants have met conditions of static stability of the atmosphere. There are no scientific studies show that wind farms causal relations and the formation of smog.
Rumor II: haze not because "nuclear"?
Allegedly, discovered under a large uranium in Ordos of Inner Mongolia coal resources by burning coal uranium into the air, which is currently widespread cause of smog. Is this for real?
The truth: smog the main influencing factors for the weather conditions. Uranium itself is a heavy element, not easily oxidized, will not be turned into dust, and power plant emissions of dust collection, desulfuration and denitrification, is there, should also be left in the combustion residue, into the air is a trace.
Rumor III: United States extreme weather due to pollution in China?
On March 8, the United States national public radio reported that "China's pollution may lead to United States cold and snowy winters", is this true?
The truth: China Meteorological Administration experts point out that "studies show that since the beginning of winter, United States Blizzard mainly polar Cold air Center frequently biased United States Atlantic and warm, humid air caused by the strong side, and not directly related to air pollution in China. "At the same time, by a number of scientists involved in the assessment of the intercontinental transfer assessment report makes it clear that, emissions of pollutants in East Asia to North America extreme weather a" contribution "is very limited.
Rumor IV: more mobile phone base station, the more radiation?
Some residents worry that community near mobile phone base stations, will have serious electromagnetic radiation, health effects, is that true?
Truth: the General mobile phone base station in urban area of radiated power is small, typical power is about 30 watts, the is 300 Watts maximum. Our living areas with mobile phone base station distances are generally in the 100 meters, 300 Watt base station 100 metres away on the radiated power density is 10 meters distance 1/100, far below the national standard of electromagnetic radiation protection regulations. So as long as the base station is 100 metres away, we don't have to worry about base stations to health hazards.
Rumors Friday: lithium batteries highly toxic pollution?
A popular network article to challenge lithium-ion batteries, lithium batteries highly toxic, short-lived, explosive, demanding; no way how to deal with the world, huge environmental pressure, really so?
Truth: China car technology research center power battery field Chief experts, and engineer Wang Fang said, lithium battery compared as lead acid, and nickel chrome, and nickel hydrogen, traditional battery, not produced any lead, and mercury, and CD, toxic harmful heavy metal elements and material, relative pollution smaller, and its electrolytic liquid for organic solvent and lithium salt, most for nontoxic or low HIV, for its environment risk relative smaller, does not into dangerous waste for management. But the hydrolysis product of decomposition or lithium-ion batteries is corrosive and toxic, experts suggest that recycling of lithium-ion batteries, the State should as soon as possible the layout.
Rumors of six: probably undrinkable groundwater resources?
An article entitled "water mapping groundwater resources: 80% not drinking" report raised concern. The paper said, after testing, China Super 80% groundwater pollution, undrinkable. Is this for real?
The truth: being prepared by the national planning of water resources protection, according to the National 4,748 municipal drinking water sources, 1817 with groundwater drinking water sources, water quality attainment rate of about 85%. Monitoring shows that in 2014, 175 water in a population of more than 500,000 of the country's major drinking water sources, a total of 33 ground water, all water quality standards. In General, groundwater quality of drinking water sources in China.
Rumor: the 9-11 is the dust layer layer of air dirty?
9-11 floor of the high-rise building is to dust, dirty air to this height will come to a halt, the highest density of pollutants here ... ... Really like this?
The truth: from a professional point of view, ground discharge of pollutants in the vertical height maximum height of the hybrid known as "boundary layer", more high mix of space, the greater the surface boundary layer air quality better. From the perspective of boundary layer, there is no layer of dust, 9-11 layer height of up to 40 meters, and always in the height of the boundary layer mixing, contaminants concentrations and surface does not vary greatly, and 20 there will not be very different.
Rumour eight: air quality in Beijing is gradually getting worse?
Some people think that Beijing's air quality deteriorated in recent years, this is really you
Truth: the recently released by the United Nations Environment Programme of the Beijing air pollution control: a 1998-2013 evaluation report: Beijing, 1998-2013 sulphur dioxide (SO2), nitrogen dioxide (NO2) and respirable particulate matter (PM10) annual average concentration has dropped dramatically, and 78% and 43%, 15 years, Beijing's air quality continues to improve. In addition, according to official data issued by the Beijing municipal environmental protection Bureau, 2015 and 2013 compared to nitrogen dioxide in Beijing fell 4.7%, respirable particulate matter down 6.1%,PM2.5 down 10%. Therefore, judging from the recent monitoring data, Beijing's air quality is continuing to improve.
Rumor: aircraft spraying treatment of white moths need to avoid?
The Internet "municipal notification: 15-20th, outside don't air your quilt, clothes, do not eat outside food (barbecue, open-air food). Minimize outdoor activities in the countryside. Aircraft spraying treatment of white moth, we pass on love ".
Truth: Beijing city forestry protection station on aircraft sub drug control forestry pest work for has explained, from May 13 began, Beijing does has is for of aircraft sub drug, locations are in five ring yiwai of, and non-population intensive district of public forest, and ecological forest and shelterbelt over, away from trees 3 to 5 meters, away from neighborhoods is far, 3 to 5 meters of height also not was wind blow bulk pharmacy; fly anti-pharmacy belongs to insects growth regulators, on animal harmless, and Beijing fly anti-forestry pest of work are has do has fast 40 years has, No escape.
Rumors of ten motor vehicle pollution are not the main cause of Beijing's air pollution?
It is said that the main cause of air pollution in Beijing is not motor vehicle emissions, industrial emissions and coal-burning, is this true?
The truth: in April 2014, the Beijing municipal environmental protection Bureau released the PM2.5 source apportionment research in Beijing. On the contribution of local pollution, vehicle emission 31.1%, coal accounted for 22.4%, 18.1%, dust 14.3% of industrial production, catering, car repair, livestock, construction and painting other emissions account for about 14.1%. Environmental experts said the vehicle emission contribution to PM2.5 in Beijing is dynamic, usually in the 10% and 50% are possible, overall average is around 30%. Therefore, motor vehicle pollution is indeed the major source of air pollution in Beijing, industrial emissions and the contribution of coal-burning air pollution in Beijing is also great.
Apart from the top ten rumours of environmental protection, pollution of the environment are published on the top ten bad habits, which are: factory indiscriminate discharge of soot, uncontrolled discharge of sewage, cars belching black smoke, use of low-grade coal, the site bare dusty, smoke, burning straw, free barbecue, open burning of garbage, pet anywhere.
On that day, the Olympic short track speed skating champion Yang Yang was appointed as the fourth Beijing environmental charity Ambassador, she will be Ambassador Ambassador and another actor Li Ji duties, conveying the positive energy to the environment. By the Beijing municipal environmental protection Federation, the Internet Society joint initiatives launched in the capital of Beijing Green Alliance also was set up at the meeting.

北京环保局发布十大谣言：风电、铀煤“躺枪”
美国极端天气源于中国污染、手机基站越多辐射越大、内蒙古风电偷走了北京大风导致雾霾、9至11层是扬灰层空气脏……在日常生活中，你是不是也时常听到这些谣言呢？6月1日，北京市环保局举办绿色传播大会，现场发布并辟谣十大环保谣言。
据北京市环保局相关负责人介绍，十大环保谣言是经过网络筛选、专家评审，因其网络传播率较高当选。在环境问题受到广泛关注的今天，环保谣言缺乏科学根据和事实支撑，颠倒黑白、混淆视听，给公众和社会造成了极大危害，不利于环保科普工作的开展和生态文明理念的传播。开展辟除环保谣言这样的活动，旨在传播环保科学知识，提高公众环保科学素养，为首都生态文明建设创造一个良好的舆论氛围。这十大环保谣言：
谣言一：内蒙古风电偷走了北京大风导致雾霾？
有媒体报道，内蒙古建设了大量风电站，偷走了北京大风，导致雾霾。这是真的吗？
真相：风碰到障碍物绕流是可以恢复的，局部风力发电或局部防护林不会对距离较远的下游风力造成影响，雾、霾形成的根本原因还是因为地面污染物碰上大气静稳条件。目前没有任何的科学研究显示风电场与雾霾的形成有因果关系。
谣言二：雾霾不散是因为“核污染”？
据传，内蒙古鄂尔多斯地下发现大规模铀煤资源，通过燃烧，煤炭中的铀进入到空气中，这是目前国内大范围雾霾的原因。这是真的吗？
真相：雾霾难散主要影响因素为气象条件。铀元素本身是很重的元素，不容易被氧化，不会变成粉尘；而且电厂对排放物都会进行除尘、脱硫脱硝，就是真的有，也应该是留在燃烧残渣里，进入空气中是很微量的。
谣言三：美国极端天气源于中国污染？
3月8日，美国国家公共电台报道称，“中国污染可能导致美国寒冷多雪冬季”，这是真的吗？
真相：中国气象局专家指出，“研究显示，入冬以来，美国暴雪频繁主要是极地冷空气中心偏向美国和大西洋暖湿气流偏强造成的，与我国空气污染没有直接关系。”同时，由多国科学家参与的评估报告《洲际传输评估报告》明确指出，东亚的污染物排放对北美极端天气的“贡献”是非常有限的。
谣言四：手机基站越多辐射越大？
有些居民担心，小区附近的手机基站，会产生严重的电磁辐射，影响健康，这是真的吗？
真相：一般城区手机基站的辐射功率都不大，典型的功率是30瓦特左右，最大的也就300瓦左右。我们的生活区与手机基站的距离一般都会在100米以上，离300瓦基站100米距离上的辐射功率面密度是10米距离上的1/100，远远低于《电磁辐射防护规定》中的国家标准。所以只要离基站100米以外，我们完全不用担心基站对身体健康的危害。
谣言五：锂电池剧毒污染大？
一篇广为流传的网文对锂电池提出质疑，称锂电池剧毒、短命、易爆炸，使用条件苛刻；怎么处理全世界都还没办法，造成巨大环保压力，真的如此吗？
真相：中国汽车技术研究中心动力电池领域首席专家、高级工程师王芳说，锂电池相比如铅酸、镍铬、镍氢等传统电池，不产生任何铅、汞、镉等有毒有害重金属元素和物质，相对污染较小，且其电解液为有机溶剂和锂盐，大多为无毒或低毒，因其环境风险相对较小，并未纳入危险废物进行管理。但锂电池分解或水解产物具有一定腐蚀性和毒性，专家建议，锂离子电池回收再利用的工作，国家应该尽早布局。
谣言六：地下水资源八成不能饮用？
一篇“水利部摸底地下水资源：八成不能饮用”的报道引发关注。该文表示，经过检测，中国超八成地下水遭受污染威胁，不能饮用。这是真的吗？
真相：正在编制的《全国水资源保护规划》显示，全国4748个城镇饮用水水源地，有地下水饮用水水源地1817个，水质达标率为85%左右。监测显示，2014年，175个供水人口50万以上的全国重要饮用水水源地中，共有33个地下水水源地，水质全部达标。总的来看，我国地下水饮用水水源地水质良好。
谣言七：9至11层是扬灰层空气脏？
高层建筑的9—11楼是扬灰层，脏空气到这个高度就会停顿，这里的污染物密度最高……真是这样吗？
真相：从专业上来说，地面排放污染物在垂直高度上混合的最大高度称为“边界层”，边界层越高混合的空间越大地表空气质量越好。从边界层的角度分析，不存在所谓的扬灰层，9层-11层高度最多40米，始终在边界层均匀混合的高度内，污染物浓度和地表不会有很大差别，和20层也不会有很大差别。
谣言八：北京市空气质量在逐步恶化？
一些人认为，北京市近年空气质量在逐步恶化，这是真的吗
真相：联合国环境规划署最近发布的《北京空气污染治理历程：1998-2013年》评估报告显示：1998至2013年，北京二氧化硫(SO2)、二氧化氮(NO2)和可吸入颗粒物(PM10)的年均浓度分别显著下降了78%、24%和43%，15年间北京的空气质量得到了持续改善。此外，北京市环保局发布的官方数据显示，2015年与2013年相比，北京的二氧化氮下降了4.7%、可吸入颗粒物下降了6.1%，PM2.5下降了10%左右。所以，从近几年的监测数据来看，北京空气质量是在持续改善的。
谣言九：飞机洒药治白蛾需躲避？
网上流传“市政府通知：15至20号室外不要晒被子，衣服，不要吃外面的食物(烧烤等露天食物)。尽量减少郊外、户外活动。飞机洒药治白蛾，大家把爱心传递下去”。
真相：北京市林业保护站对飞机撒药防治林业病虫害工作进行了解释，从5月13日开始，北京市确实有正在进行的飞机撒药，地点都在五环以外的、非人口密集区的公益林、生态林和防护林上空，离树梢3至5米，离居民区很远，3至5米的高度也不会被风吹散药剂；飞防药剂属于昆虫生长调节剂，对人畜无害，而且北京飞防林业病虫害的工作都已经做了快40年了，不用躲避。
谣言十：机动车污染不是北京空气污染的主要原因？
有人说，北京市空气污染的主要原因不是机动车排放，而是工业排放和燃煤，这是真的吗？
真相：2014年4月，北京市环保局正式发布了北京市PM2.5来源解析最新研究成果。在本地污染贡献中，机动车排放占31.1%、燃煤占22.4%、工业生产占18.1%、扬尘占14.3%，餐饮、汽车修理、畜禽养殖、建筑涂装等其他排放约占14.1%。环保专家表示，机动车排放对北京市PM2.5的贡献是动态的，平时在10%到50%之间都有可能，总体来说其平均值就是30%左右。因此，机动车污染确实是北京空气污染的主要来源，工业排放和燃煤对北京市空气污染的贡献也很大。
除十大环保谣言之外，会上还发布了污染环境十大陋习，其分别是：工厂随意排放烟尘、任意排放污水、汽车冒黑烟、使用劣质煤、工地裸露尘土飞扬、乱排油烟、焚烧秸秆、随意露天烧烤、露天焚烧垃圾、宠物随地大小便。
当日，奥运短道速滑冠军杨扬被聘任为第四届北京环保公益大使，她将和另一位大使演员李晨共同履行大使职责、传递环保正能量。由北京市环保联合会、首都互联网协会等共同倡议发起的北京绿色传播联盟也于会上宣告成立。
