雾霾形成的主要气体被发现为氨,山西TT废气处理(深圳海德隆山西办)和您一同分享:???

The main gas haze formation was found for ammonia, Shanxi TT gas processing (Shenzhen Haidelong Shanxi Office) to share with you:

关于大气中的氨气,第一份全球性的长期卫星研究揭开了世界上四个最具农业生产力的地区这一“热点”污染物的面纱。使用来自NASA大气红外探测器(AIRS)的卫星数据,美国马里兰大学领衔的科研团队发现,2002—2016年,氨浓度在美国、欧洲、中国和印度稳步上升。???

On the atmosphere of ammonia, the first global long-term satellite research has opened up the world's four most productive areas of agriculture, the "hot" pollutants veil. Using satellite data from the NASA atmospheric infrared detector (AIRS), led by the University of Maryland, the research team found that from 2002 to 2016, ammonia concentration in the United States, Europe, China and India rose steadily.??????

这项研究发表在近期的《地球物理研究通讯》上,还描述了各地区大气氨含量增加的可能原因。尽管各地具体情况不尽相同,但大体上说,氨的增加与作物肥料、畜禽废弃物、大气化学变化、增温土壤有关系。???

The study, published in the recent issue of the Journal of geophysical research, describes the possible reasons for the increase in atmospheric ammonia concentrations in various regions. Although the specific situation is not the same, but in general, the increase in ammonia and crop fertilizer, livestock waste, atmospheric chemical changes, warming soil.??????

大气氨含量增加与空气、水质量差相关。研究结果或有助于启迪人们控制农业地区氨污染、氨副产品的管理策略。???

The increase of ammonia concentration in air is related to poor air and water quality. The results of this study may be helpful to inspire people to control the ammonia pollution in agricultural areas and the management strategy of ammonia byproducts.??????

马里兰大学大气和海洋科学专家Juying Warner表示,“从地面测量氨是困难的,但团队开发的以卫星为基础的方法使我们更有效、更准确地追踪它。我们希望这一结果更好地帮助人们进行氨排放管理。”???

"It is difficult to measure ammonia from the ground," said Juying Warner, an expert on atmospheric and Ocean Sciences at the University of Maryland, but the team developed a satellite based approach that allows us to track it more efficiently and accurately. We hope that this result will help people better manage ammonia emissions."??????

气态氨是地球氮循环的一个自然部分,但过量氨对植物有害,并降低空气和水质量。在对流层,它与硝酸、硫酸反应,形成危害人体健康的硝酸盐颗粒;进入湖泊、溪流和海洋,造成富营养化,形成低氧水平的“死亡地带”。???

Gaseous ammonia is a natural part of the earth's nitrogen cycle, but excessive ammonia is harmful to plants and reduces air and water quality. In the troposphere, it react with nitric acid and sulfuric acid to form nitrate particles that are harmful to human health, and enter the lakes, streams and oceans".??????

“很少有氨是从排气管、烟囱中来的,主要是农业领域,来自肥料、畜牧。”马里兰大学教授Russell Dickerson说,“它对生态系统产生深远影响。在切萨皮克湾氨污染中,大气中的氨贡献了1/4,造成了富营养化,导致了使牡蛎、蓝蟹和其他野生动物生活变困难的‘死亡地带’”。???

"There are very few ammonia from the exhaust pipe, chimney, mainly in the field of agriculture, from fertilizer, animal husbandry." "It has a profound impact on the ecosystem," said Russell Dickerson, a professor at University of Maryland. Ammonia pollution in the Chesapeake Bay, ammonia in the atmosphere contributed to 1/4, resulting in eutrophication, resulting in the oysters, blue crabs and other wildlife life difficult to death zone".??????

该研究中涉及的每个主要农业区2002—2016年的氨增加都有着不同的原因。例如美国,没有经历肥料使用量的大幅增加或化肥施用方式的重大变化,但Warner、Dickerson等人发现,20世纪90年代通过立法来减少酸雨竟意想不到地增加了大气中的氨,因大气中的酸通常会去除氨。???

There are various reasons for the increase in ammonia from 2002 to 2016 in each of the major agricultural areas involved in the study. For example, the United States, did not experience significant changes in fertilizer use or a significant increase in the amount of fertilizer application methods, but Warner, Dickerson et al, 1990s to pass legislation to reduce acid rain unexpectedly increased ammonia in the atmosphere, because the atmosphere will usually remove ammonia acid.??????

在4个主要农业生产区,欧洲经历了最戏剧性的氨含量变化。研究人员认为,这很大程度上是因为对富氨肥料的成功限制和改善动物粪便处理的做法。另外和美国一样,也与大气中酸性物质有关。???

In 4 major agricultural production areas, Europe experienced the most dramatic changes in ammonia content. The researchers believe that this is largely due to the success of the restrictions on the use of ammonia fertilizer and improve the practice of animal manure treatment. In addition, as in the United States, it is also related to atmospheric acidity.??????

中国大气中氨增加的原因复杂且互相作用。该研究者认为,限制二氧化硫——硫酸的关键前体的努力或许是一个责任因素。但中国从2002年开始也大力拓展了农业活动,增加了含氨肥料和动物粪便中氨的排放量。农业土壤变暖也与氨增加有关。???

The reasons for the increase of ammonia in the atmosphere of China are complex and interactive. The researchers argue that efforts to limit the key precursors of sulfur dioxide, sulfuric acid, may be a liability. But China has also expanded agricultural activities since 2002, increasing the amount of ammonia in ammonia and animal waste. Agricultural soil warming is also associated with increased ammonia.??????

“氨增加让悬浮颗粒着陆中国,而它是北京冬季厚厚的雾霾的主要贡献者。”Warner说,“肉类日渐成为中餐饮食一个更受欢迎的部分。随着饮食由素食为主向肉食转变,氨排放量将继续上升。”???

Ammonia increased to allow suspended particles landing in China, which is the main contributor to the thick fog in winter in Beijing." "Meat is becoming a more popular part of Chinese food," Warner said. As the diet changes from meat to meat, ammonia emissions will continue to rise."??????

在印度,化肥的大量使用加上牲畜粪便累积,导致了世界上最高浓度的大气氨。但研究人员也注意到,氨增加的速度没有其他地区快。他们认为可能是由于酸雨前体的排放量增加。???

In India, the heavy use of chemical fertilizers, combined with the accumulation of livestock manure, has led to the world's highest concentration of ammonia in the atmosphere. But the researchers also noted that the rate of increase in ammonia is no faster than other regions. They think it may be due to increased emissions of acid rain precursors.??????

研究人员将所有上述地区氨增加的一部分原因归于气候变化。氨更容易从温暖的土地里挥发出来,而每个地区的土壤自2002年以来呈现出一年年变暖的趋势。??? The researchers attributed some of the increase in ammonia to climate change. Ammonia is more likely to evaporate from warmer soil, and the soil in each region has been warming year by year since 2002.??????

“这些分析为我们假设一段时间内大气究竟发生了什么提供了第一份证据。”Warner表示,“我们希望从其他来源如联合极轨卫星系统获得更多数据,以便将来建立更清晰的画面。”???

"These analyses provide the first evidence of what happens in the atmosphere over a period of time." Warner said, we hope to get more data from other sources such as the joint polar orbit satellite system, in order to establish a clearer picture."??????

Warner、Dickerson等人希望更好地了解大气中的氨后,帮助政策制定者平衡高需求的农业与环境保护之间的关系。???

Warner, Dickerson et al. Hope to better understand the relationship between the high demand for agriculture and environmental protection after the ammonia in the atmosphere.??????

Dickerson表示,人口日益增长,食物特别是肉食需求也在上升,这意味着农民和牧场主需要更多的肥料,也就造成了干净的空气和水更难以维持,“智慧农业的实践或许可减少排放温室气体,帮助避免不利影响”。(王方编译)???

Dickerson said that a growing population, especially the carnivorous food demand is also rising, which means that farmers and ranchers need more fertilizer, also resulted in the clean air and water is more difficult to maintain, or the "practice license of wisdom agriculture to reduce greenhouse gas emissions and help avoid adverse effects".
