How is the smog formed?

Haze is caused by environmental pollution.

Haze is caused by environmental pollution.

With the deterioration of air quality, cloudy days are increasing and the harm is increasing. In many areas of our country, the smog weather phenomenon is combined with fog as an early warning and forecast of disastrous weather. Collectively referred to as "haze weather". In fact, fog and haze are completely different to some extent. For example, when fog appears, the air is humid; When smog occurs, the air is relatively dry and the relative humidity of the air is usually below 60%. The reason is a large number of extremely fine dust particles, smoke particles, salt particles and so on. Float evenly in the air, so that the air with effective horizontal visibility less than 10KM can be mixed. Puweixin Tomcat imported from the United States effectively prevents smog.

Explain the source of smog in China in English.

Haze is a kind of air pollution, which is mixed with dust and other dry particles, which blurs the clarity of the sky and its interaction with the natural environment. Haze is air pollution and dry particles such as dust and smoke, which cover up the clear sky and interact with the natural environment.

Haze cause

This air pollutant comes from various natural and man-made sources. Natural sources include wind-blown dust and soot from wildfires. Man-made sources include motor vehicles, industrial fuel combustion and production operations. One of the main causes of smog is production operation. Many factories emit excessive exhaust gas, which seriously affects air pollution.

This air pollutant comes from various natural and man-made sources. Natural sources include wind and sand, smoke and dust from forest fires. Man-made sources include motor vehicles, industrial fuel combustion and manufacturing. One of the main reasons for exposure to smog is manufacturing. The smog produced by many factory measurements has seriously affected the standards and smog, and the air has become air pollution. Usa tmall wechat

Hazards of smog

The components that make up smog may have a negative impact on people's health, especially children and the elderly. People with certain diseases, such as asthma, allergies, European and lung diseases, are not excluded. Workers who work in the open air have high health risks. The smog formed by ingredients may have a negative impact on people's health, especially children and the elderly. Some diseases, such as asthma, allergies, pneumonia and lung diseases, are not excluded. Workers who work in the open air have high health risks.

solution

One of the effective solutions to help eliminate smog is to make some chemical changes in the manufacturing process, so it can reduce the harmful emissions generated by manufacturing business.

How did the smog come from and how to solve it?

Car accidents often happen, so I must be very careful when crossing the road. Because of the bad weather. So ... Every morning, I can only see buildings dozens of miles away, and the air is polluted by haze. I did as she said. My mother told me to put on a respirator. The weather is really bad these days. When I open the curtains, I even feel difficult to breathe. When I go to school. There is fog and mist in the air, so we can't see things far away. Besides. I hope drivers can drive more carefully and keep safe.

How is the smog formed?

Haze is a combination of fog and haze. Because of the deterioration of air quality, cloudy days have increased and the harm has increased. In many areas of our country, the smog weather phenomenon is combined with fog as an early warning and forecast of disastrous weather. Collectively referred to as "haze weather". Composition and causes of smog. Sulfur dioxide, nitrogen oxides and inhalable particles are the main components of smog. The first two are gaseous pollutants, and the last particulate matter is the chief culprit that aggravates smog weather pollution. They combine with fog and instantly turn the sky gray. The English abbreviation of particulate matter is PM, and now the high-frequency vocabulary of air PM2.5 refers to pollutant particles with a diameter less than 2.5 microns. This particle itself is not only a pollutant, but also a carrier of toxic substances such as heavy metals and polycyclic aromatic hydrocarbons. Second, the source of toxic particles in cities: first, automobile exhaust. Large vehicles that use diesel are "recidivists" who emit fine particles, including buses, shuttle buses of various units and large transport trucks. Small cars that use gasoline emit gaseous pollutants, such as nitrogen oxides, which are easily converted into secondary particulate pollutants in foggy days, aggravating smog. The third is the waste gas produced by burning coal for heating in winter in the north. Fourth, it is the waste gas emitted by industrial production. For example, industrial kilns and boilers in metallurgy and electromechanical manufacturing industries, as well as a large amount of waste gas generated by the combustion of automobile repair and painting and building materials production kilns. 5. Dust generated by construction sites and road traffic. Haze weather hazards. Effects on respiratory system. The composition of smog is very complex, including hundreds of atmospheric chemical particles. Among them, aerosol particles smaller than 10 micron are harmful to health, such as mineral particles, sea salt, sulfate, nitrate, organic aerosol particles, fuel, automobile exhaust, etc., which can directly enter and adhere to human respiratory tract and alveoli. In particular, submicron particles will be deposited in the upper and lower respiratory tract and alveoli respectively, causing acute rhinitis and acute bronchitis. For patients with chronic respiratory diseases such as bronchial asthma, chronic bronchitis, obstructive emphysema, and chronic obstructive pulmonary disease, smog weather will make the condition acute or acute. Staying in this environment for a long time will also induce lung cancer. Second, the impact on the cardiovascular system. There are many pollutants in the air in foggy days, and the air pressure is low, which is easy to induce acute attacks of cardiovascular diseases. For example, when the fog is heavy, the water vapor content is high. If people exercise outdoors, the sweat of human body is not easy to be discharged, which causes people to feel chest tightness and blood pressure to rise. Third, the smog weather will also lead to the weakening of ultraviolet rays in the surface layer, which can enhance the activity of infectious bacteria in the air and increase infectious diseases. Fourthly, due to the decrease of sunshine, insufficient ultraviolet radiation for children, insufficient production of vitamin D in the body and greatly reduced absorption of calcium in foggy days, rickets in infants and young children will be seriously caused, which will slow down the growth and development of children. Fifth, it affects mental health. The gloomy and foggy weather is prone to mental laziness, depression and pessimism due to the weak light and low air pressure, and even it is easy to get out of control at the slightest sign of trouble. Sixth, it affects traffic safety. In foggy weather, the visibility of the visual field is low and the air quality is poor, which is easy to cause traffic jams and traffic accidents.
