Information about smog is 50 words.
Information about smog is taken from 1999. Tips on mine safety layout: Most people often mention smog now. In fact, fog and haze are two words, which are composed of fog and haze. Fog, mainly a weather phenomenon that often occurs in the morning and evening, is the condensation of suspended water vapor in the atmosphere, which reduces visibility. Generally, the visibility of fog is less than 1000 meters. Haze is a visual obstacle caused by an aerosol system consisting of a large number of particles suspended in the air. (Note: The relative humidity of smog is very small, and the composition of smog is composed of a large number of particles. ) Fog is the condensation of water vapor, and haze is composed of particles. Generally, fog is less harmful to human body, while smog is more harmful to human body.
It is said that some cities have begun to manually remove fog and haze with vehicle-mounted sprayers, and the effect is not bad. I hope it can be popularized, so that smog can be minimized and people can live better.

Haze (wü má i, expressed in English as *** og/haze) is a combination of fog and haze. Smog is very common in cities. In many areas of China, fog and haze are combined as disastrous weather phenomena for early warning and forecasting, which are collectively called "haze weather". Haze is the result of interaction between specific climatic conditions and human activities. The economic and social activities of high-density population will inevitably emit a large number of fine particles. Once the emission exceeds the circulation capacity and carrying capacity of the atmosphere, the concentration of fine particles will continue to accumulate. At this time, if it is affected by calm weather, it is easy to have a wide range of smog. [1] In 2065438+03, "smog" became the key word of the year. In June 5438+10, four smog processes enveloped 30 provinces (autonomous regions and municipalities). In Beijing, only five days are not foggy. It is reported that less than 65,438+0% of the 500 largest cities in China meet the air quality standards recommended by the World Health Organization. Meanwhile, among the 65,438+00 most polluted cities in the world, 7 are in China. 2014,6543814, the national disaster reduction office and the Ministry of civil affairs listed the haze weather that is harmful to health as a natural disaster for the first time in 20 13 years. 2065438+February, 2004, * * * pointed out during his inspection work in Beijing that the primary task of controlling smog pollution and improving air quality is to control PM2.5, and major measures should be taken from the aspects of reducing coal burning, strictly controlling vehicles, adjusting industries, strengthening management, joint prevention and control, and managing according to law, highlighting key areas, strictly assessing indicators, strengthening environmental law enforcement and supervision, and earnestly investigating responsibilities.

Information about smog (in a word) smog is a mixture of fog and haze, and its core substance is smoke, dust and other substances suspended in the air.
Haze data Since the 1980s, almost every year 1 1 month, there will be haze weather in North China, mainly climate and pollution. Due to the large temperature difference between day and night in summer and autumn, the weather is calm and stable, which is not conducive to pollutant discharge.
Peng, a researcher at the National Urban Environmental Pollution Control Technology Research Center, believes that this has a lot to do with the low temperature and high humidity in autumn, which is easy to form foggy days.
In addition, due to the high accumulation of pollutants, big cities are more prone to smog. Some people question why there are not many motor vehicles in Beijing during the holidays and why the smog is serious. Peng said that traffic changes will not have a great impact on the air in the short term.
Smog is called a healthy "invisible killer". Zhong Nanshan, an academician of China Academy of Engineering, told the reporter that in the past, air pollution was mainly dust, but now the smog is actually carbon monoxide and nitrogen oxides. If the smog is mixed with harmful substances, it will have direct harm to health, including damage to the nervous system, cardiovascular system, respiratory system and endocrine system.
To deal with smog, Omron and other brands of home medical atomizers are necessary amulets for many families, but to fight smog, smog must be removed. China Center for Disease Control and Prevention announced that it will take three to five years for China to establish a nationwide air pollution (smog) health impact monitoring network to grasp the air pollution exposure level and the changing trend of population health impact.
The smog information is about 40 words, which is a general term for smog, fog and haze. But fog is fog, haze is haze, and fog and haze are very different.
Haze refers to the haze caused by dust, sulfuric acid and nitric acid in the air. The difference between haze and fog is that the relative humidity is small when haze occurs, but it is saturated in fog (if there are a large number of condensation nuclei, the relative humidity may not reach 100%, and saturation may occur).
Suggestions about smog are 50 to 60 words, dear friends:
Caring for the environment and cherishing the space for human survival and development are the basic qualities necessary for modern people. "Environmental awareness and environmental quality are important indicators to measure the degree of civilization of a country and a nation". Carrying out environmental education and improving the environmental awareness of the whole nation are the most fundamental and effective measures and means to solve environmental problems. Caring for the earth, maintaining ecology and protecting the environment is the unshirkable responsibility of every citizen. Green is widely developed! Establishing and advocating green civilization is a new fashion and the embodiment of social progress. In order to further promote our environmental protection work, enhance environmental awareness and cultivate good environmental ethics and behavior habits, I will create a green society as the key work this year, so we propose:
First, actively cooperate? Carry out green activities, popularize and deepen environmental education, and bring green hope into future life.
Second, study hard on environmental protection knowledge, earnestly grasp the contents of environmental aspects in textbooks of various subjects, do a good job in environmental protection publicity in combination with environmental-related anniversaries, and participate in community environmental protection practice and supervision.
Third, start from me, start from now, and start from the little things around you. Advocate green life, save resources, reduce pollution, recycle resources, green consumption and support environmental protection; Really cherish life and don't destroy flowers and trees; No smoking, no littering; Do not use disposable bowls and chopsticks, and use less stationery that is difficult to degrade; Support. Garbage sorting and recycling.
Fourth, actively and seriously participate in the greening, beautification and purification of residential quarters and public places, and eliminate or consciously control the pollution generated in daily life.
Fifth, comprehensively improve the awareness of environment and development, and establish correct environmental values and environmental ethics; Take the responsibility of environmental protection and promote the sustainable development of society, economy and environment. It's time to pay attention to our earth home, launch green action and advocate green civilization.

There is an urgent need for 50 words of information about smog! Haze, also known as haze and ash haze (haze), refers to the turbidity caused by a large number of particles such as smoke and dust suspended for unknown reasons. From the meteorological point of view, the difference between fog and haze mainly lies in the size of water content: fog is called when the water content is above 90%, and haze is called when the water content is below 80%. The core substance of smog is dust particles suspended in the air, which are called aerosol particles in meteorology. With the gradual deterioration of air quality, "smog" weather phenomenon appears more and more frequently, which contains hundreds of atmospheric chemical particles, among which aerosol particles are the most harmful to health, such as mineral particles, sulfate, nitrate, fuel and automobile exhaust, which invade human respiratory tract and lungs without people's defense, thus causing respiratory diseases, cardiovascular diseases, blood system, reproductive system and other diseases, such as pharyngitis, emphysema, asthma, rhinitis and so on. Smog also often causes traffic accidents.
