Haze handwritten newspaper content data daquan

Haze is a combination of fog and haze. Smog is very common in cities. Haze weather has become a disastrous weather. Prevent smog and give me back the blue sky. The following is the complete collection of the contents and materials of the smog handwritten newspaper, which I carefully compiled, for your reference only, and I hope it will help you.

Haze handwritten newspaper content data daquan 1 smog hazard

Upper respiratory tract infection (URTI)

Hazy weather, a large number of dust particles, smoke particles and other harmful substances floating in the air will cause harm to the human respiratory tract. A large number of particles, dust, pollutants and viruses floating in the air, once inhaled by the human body, will stimulate and destroy the respiratory mucosa, dry the nasal cavity, destroy the defense ability of the respiratory mucosa, and bacteria enter the respiratory tract, which is easy to cause upper respiratory tract infection.

bronchial asthma

The air pollution in foggy days is heavier than usual, and bacteria and viruses often exist in the air, which is easy to lead to the spread of infectious diseases and the occurrence of various diseases. In particular, air pollutants in cities are not easy to spread, which aggravates the toxicity of sulfur dioxide, carbon monoxide, nitrogen oxides and other substances and will seriously threaten people's lives and health. In foggy days, dust and smoke are floating in the air, and dust mites may also be suspended in the fog. Inhalation of these allergens by patients with bronchial asthma will stimulate the respiratory tract and cause asthma symptoms such as cough, sulking and poor breathing.

lung cancer

Professor Kan Haidong from the School of Public Health of Fudan University said that the incubation period of lung cancer ranges from several years to decades, and children's childhood lung cancer may be related to genetic factors and gene mutations. However, compared with adults, children's height determines that they are indeed more susceptible to automobile exhaust and road dust, which is recognized by the medical community. Because children's breathing zone is just close to the height of waste gas, at the same time, children's exposure per unit weight is higher than that of adults, which leads to their higher susceptibility, so they are more susceptible to pollution gases such as waste gas and smog. In addition, children's body organs are not fully developed, and the invasion of polluted gas causes more harm.

conjunctivitis

According to experts, particulate matter attached to the cornea in foggy days may cause keratitis and conjunctivitis, or aggravate the condition of patients with keratitis and conjunctivitis. Patients with keratitis and conjunctivitis have increased significantly, including the elderly and children, as well as office workers who face computers all day. Everyone has the same situation: dry eyes, soreness, tingling, redness and allergies.

Infantile rickets

The Environmental Research Institute of China Center for Disease Control and Prevention spent a year studying the effects of smog on human health.

The preliminary study found that the smog weather not only led to an increase in the incidence/hospitalization rate of respiratory diseases, but also had some indirect effects on human health. Haze will weaken ultraviolet radiation. If smog often occurs, it will affect the synthesis of vitamin D in human body, lead to a high incidence of rickets in children and enhance the activity of infectious bacteria in the air.

The main source of smog is the content and materials of smog handwritten newspaper.

human factor

Sources of toxic particles in cities:

First: it's automobile exhaust. Large vehicles that use diesel are "recidivists" who emit PM 10, including buses, shuttle buses of various units and large transport trucks. Sources of toxic particulate matter in cities: firstly, automobile exhaust. Cars that use diesel are "habitual criminals" who emit particles. 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.

Vehicle exhaust is the main component of smog particles. According to the latest data, motor vehicle exhaust accounts for 22.2%, coal combustion accounts for 16.7%, dust accounts for 16.3%, and industry accounts for 15.7%. However, with the development of automobile technology and the improvement of oil quality, environmental managers have found that motor vehicle exhaust does not play a decisive role in the formation of haze weather. However, as some cities with large car ownership, managers still need to control vehicle emission standards to avoid the formation of haze weather.

Second: the waste gas produced by burning coal for heating in winter in the north.

Third: the waste gas emitted by industrial production. For example, metallurgy, kilns and boilers, electromechanical manufacturing, automobile repair and paint and building materials production produce a lot of waste gas from kiln combustion.

Fourth: Dust generated by construction sites and road traffic.

Fifth, particles can grow. The particle size of bacteria and viruses is equivalent to PM 0. 1 ~ PM 2.5. When the humidity and temperature in the air are appropriate, microorganisms will attach to particles, especially oil fume particles. After absorbing oil droplets, microorganisms will be transformed into more microorganisms, which will increase the number of biological toxic substances in smog.

6. Dust "smog" will also be produced in home decoration. Indoor dust is pervasive, which is not only harmful to the health of staff and users, but also increases the cleaning burden. When the dust is serious, it also brings many hidden dangers to the decoration project.

In addition to meteorological conditions, the increase of atmospheric particulate matter (including coarse particulate matter PM 10 and fine particulate matter PM2.5) caused by industrial production, vehicle exhaust emissions and coal burning in winter is an important factor of smog. At present, the level of pollutant discharge in many cities is at a critical point, which is very sensitive to meteorological conditions. When the diffusion conditions are good, the air quality can reach the standard, and once adverse weather conditions are encountered, the air quality and visibility will drop immediately.

climatic factor

"There is a difference between fog and haze. Fog refers to the weather phenomenon that the visibility is lower than 1 km due to the condensation of suspended water vapor in the atmosphere. The formation of smog is mainly the result of a large number of suspended particles in the air and meteorological conditions. There are three reasons:

First, the phenomenon of static wind in the horizontal direction has increased.

The higher the buildings are built in the city, the obstruction and friction of airflow passing through the urban area will be obviously weakened. The increase of static wind phenomenon is not conducive to the diffusion and dilution of suspended particles in the atmosphere, and it is easy to accumulate around urban areas and suburbs.

Second, the vertical direction is reversed.

The inversion layer is like a pot cover over a city. This inversion phenomenon that the upper air temperature is higher than the lower air temperature limits the vertical movement of the lower air, making it difficult for suspended particles in the air to drift to the upper air and be blocked at the lower air and near the ground.

Third, the increase of suspended particulate matter and organic pollutants in the air.

With the growth of urban population and industrial development, the number of motor vehicles has surged, resulting in a large increase in pollutant emissions and suspended solids.

The contents and materials of the smog handwritten newspaper Daquan 4 pay attention to the protection of special people in smog weather.

In response to the smog weather, the elderly, children, outdoor workers (such as traffic police and construction workers), pregnant women and patients with chronic diseases are treated separately according to the differences in age, occupational nature and special physiological status.

Protect the elderly

Old people spend more time indoors, so they should pay special attention to cleaning. Old people who are used to sweeping the floor with brooms might as well use vacuum cleaners, carpets, rags and sofa cover to clean in time. Traditional cooking methods, such as frying and frying, often produce a lot of oil smoke and pollute indoor air. It is recommended to cook at home by steaming and cooking.

Protect children

Children's physical development is incomplete, and dust and particulate matter in foggy weather will directly infringe on their health through their respiratory tract, which is easy to cause respiratory diseases such as colds, coughs, rhinitis, bronchitis and asthma. The protection of children is carried out in the following aspects.

First of all, through school publicity and knowledge popularization, children can have a direct and sensory understanding of haze weather and its impact on health.

Secondly, raise parents' awareness of children's methods.

Thirdly, reduce outdoor activities and change outdoor activities into indoor activities, thus reducing the impact of smog on children.

In addition, in plain life, there are more dust and bacteria on the surface of plush toys, so try to play with children less or clean them often, so as to keep children's activities away from heavily polluted traffic arteries and avoid opening windows for ventilation during peak hours.

Protection of outdoor workers

The continuous occurrence of smog weather will make many people uncomfortable on outdoor main roads, but generally speaking, we spend less time outdoors and spend most of our time indoors. But for workers who need to work outdoors for a long time, such as construction workers, sanitation workers, traffic police, etc. They are exposed to smog for a longer time and have a greater exposure. Therefore, it is necessary to emphasize and attach importance to the protection of outdoor workers against haze weather.

Protect pregnant women

Pregnant women should rest properly, avoid overwork, ensure adequate sleep and reduce psychological stress. At the same time, pregnant women should not rest blindly, but should exercise properly and maintain an optimistic mood.

1, eat more foods containing zinc. 2. supplement vitamin C. Improve the relative humidity of indoor air.
