Security guards Raiders

Just in December, a large area of ​​hazy weather in China's central and eastern regions ushered in. Most of the cities in the Yangtze River Delta and the Pearl River Delta have failed to survive. The air quality in southern Hebei, most of Shandong, most of Jiangsu, and northern Zhejiang is heavily polluted to serious pollution. According to statistics from the Central Meteorological Observatory, as of 18:00 on the 4th, there have been haze events in 25 provinces (regions, cities) in different degrees. Among them, the embarrassment of the Su Shi and Other places is the most serious, and the “heavy disaster area” of the dense fog is located in the southwest and the Jianghuai area. It is expected that adverse weather conditions will continue from the 4th to the 8th.

According to experts, the main feature of the winter haze is that due to the radiative cooling of the surface at night, it is easier to condense vapor in the surface gas layer and form a relatively common radiation fog in the winter.

The damage caused by radiation fog damage will reduce the visibility, and will have a greater impact on traffic (urban traffic, highways, airport flights, land and water transportation, etc.).

Radiation fog is the most common kind of fog in the winter, but it does not have radiation damage to the human body. However, when the fog is filled, poisonous and harmful substances in the air may undergo a series of physical and chemical reactions with atmospheric pollutants, thereby generating new substances. For example, sulfur dioxide is oxidized in the atmosphere and combined with mist to form sulfuric acid aerosol. The toxicity of this new substance is several times higher than that of the original material. In addition, when there is heavy fog, there is often an inversion layer, air cannot convective, and pollutants in the air are difficult to spread, so it is harmful to the human body.

Therefore, it is suggested that everyone should avoid the harmful effects of radiation fog on our lives and travel while away from the hazards of smog.

Fog Weather Driving Considerations Summarizing smog also has a serious impact on our daily lives, seriously endangering citizens' personal health, and haze like a devil invades our bodies. The visibility of roads in fog and haze weather is low, and this unfavorable weather conditions will continue, and there will be moderate to severe haze in Jiangsu, Zhejiang, Shanghai and the eastern part of Anhui Province. Xiao Bian now summarizes the past fog driving precautions and hopes to help drivers and friends.

1. Keeping a low speed When driving in the fog, strictly observe the traffic laws and regulations, and do not drive fast. The greater the fog, the shorter the visual distance and the lower the speed. When entering densely fog-filled areas, it is also necessary to slow down in advance, and it is very likely that accidents will occur in front of it. If visibility is less than 10 meters, it is recommended not to drive. Friends already on the road can choose to wait in a safe place to stay, but remember to turn on double flash and place a triangle.

2. Do not use high beam headlights. Fog headlights and front and rear fog lights should be turned on to remind you of the position of the vehicle behind you. If you are driving on a highway or in heavy fog, you must open double flashes. Special reminder, fog should not use high beam lights, experienced driver friends should be clear, after opening the high beam lights in front of a white one, what can not see clearly.

3. Do not blindly pass over ordinary roads. If you find that there is a vehicle parked on the roadside in front of you, it is best not to blindly pass the vehicle because it is likely to be waiting for the traffic coming from the opposite side. In addition, fog should be rolled on the rolling line to prevent collision with the target car.

4. When the sudden incident opens the double flash, it will meet the sudden situation. Immediately after parking, the double flash shall be turned on to remind the rear vehicle to pay attention. When warning signs are placed, they should be farther away than usual to ensure that the rear vehicles find dangers earlier and take measures to deal with them. In addition, people in the car should also immediately evacuate to a safe place on the roadside, and promptly report to the police. Don't stay in the car or walk in the driveway to avoid secondary accidents because you stop the car and the car behind you may not stop.

5. Toll station please slow down when entering the toll station should be particularly cautious, the control of the bad speed is likely to be in front of the vehicle waiting for payment to the rear-end, and may even hit the toll station. In general, there will be a turbulent marking at a place 500 meters before the entrance of the toll station. When the oscillating marking on the vehicle rolling occurs vibration, it must be decelerated immediately. However, if it is a case of fog not see the toll station, it is recommended that you do not open such a quick shock line to remind you.

6. Careful attention must be paid when the service area passes through the service area. When encountering a fuel shortage, many vehicles may have long queues outside the service area. More people who do not obey the traffic rules think of a queue to park the vehicle in the lane. If they do not dodge, it is very likely that an accident will occur. Please walk slowly through the service area.

7. Inquire about weather conditions in advance Before we get out of the train, we should pay more attention to the weather conditions of the road sections we are going through. If due to the weather, the highway to be passed through is subject to traffic control, please arrange a reasonable route or wait. For the arrangement of detour routes, attention should be paid to height restrictions and restrictions on vehicles.

8. Routine inspections prior to driving before leaving the car are also topics we often talk about. We should do it regardless of the weather conditions. When a vehicle fails on the road, it is best to choose a safe parking lot and set a safety sign. After all, parking on the Foggy Expressway is not a joke.

The haze weather is rampant. How to choose a mask to reduce the harm under the haze. Many netizens choose to wear masks to travel. Mask sales have increased dramatically, especially masks with anti-fog and anti-dust functions. Therefore, one sees such a scene on the streets. Everyone wears masks to travel. Wearing masks in smog weather has a certain barrier effect on PM2.5, but according to experts, not every type can achieve the best results. Which kind of mask can effectively block PM2.5 particles?

1, wearing a mask of activated carbon most useful these past few days, Beijing suffered the fourth haze of the month. In order to be healthy, people started to use protective measures, and various masks also became popular. So, which kind of mask can effectively block PM2.5 particles?

After testing, it was found that masks with activated carbon filters are more suitable for wearing in hazy weather. On the contrary, gauze masks almost do not block the fine particles.

2, masks also pay attention to anti-bacterial "For masks, there are two aspects worth noting, one is effective isolation of PM2.5 particles, and the other is to resist the breeding of bacteria." Experts, due to N95 mask compared to one-time The price of masks is high, so many people are reluctant to use them and throw them away. Most of them are used repeatedly. This requires attention to the problem of bacterial growth. In the process of wearing a mask, the outer layer of the mask often accumulates a lot of dust, bacteria and other dirt in the outside air, while the inner layer blocks the exhaled bacteria and saliva. In a hot and humid environment, these bacteria are prone to breeding and are not good for the human body. "And disposable masks such as the N95, it is best not to use repeatedly, to avoid secondary pollution."

How do haze weather protect your lungs?

Today, the air quality of large, medium and small cities can be described as one day less than a day, and air pollution is raging. This is a serious threat to people's health, and the lungs are the first to suffer. According to newspaper reports, in Beijing, lung cancer has been the highest among all kinds of cancer for 6 years. How can we protect our lungs under increasingly serious environmental pollution?

1. The lungs must be actively filled with water and medicine: “The lungs are hi moist and dry”, which makes sense. Therefore, the best way to keep the lungs is to actively supplement the water. The first is to take the initiative to drink water: it is best to actively drink 6-8 glasses of water every day. Among them, a glass of water is most important in the morning and drinking water in the early morning can relieve the lack of water in the respiratory tract. Secondly, it must be nursed from the inside to give the body sufficient moisture. In addition, the diet should be light, eat spicy, fried and smoked products.

2, eat more fruits and vegetables to raise the lungs, but also in the daily diet intake of enough fruits and vegetables. Foods that are beneficial to the lungs include some cruciferous plants such as broccoli, kale, etc. These vegetables contain sulforaphane, which helps the lungs to remove harmful bacteria;

There are also apples, apple pectin is rich in pectin and antioxidants, can reduce the inflammation of the lungs; and animal liver, egg yolk, dairy products, vitamin A content is the most abundant, can reduce the deterioration of lung function.

3, exercise can prevent lung inflammation Brazilian researchers found that: aerobic exercise can help prevent lung inflammation, but also to curb the exposure to air pollution, the emergence of pro-inflammatory effects. The best time to raise lungs during the day is around 8am. It is best to do some aerobic exercise such as walking, jogging, Tai Chi and so on.

4, regular lung examination, the emergence of lesions should be treated as soon as possible any disease does not suddenly come, because our body has a certain degree of compensation, if the lung lesions below 50%, the body is likely to have no feeling; The lesion is more than 50%, which exceeds people's compensatory ability and begins to show clinical symptoms. It is too late to seek medical treatment at this time. Therefore, people over the age of 40 should regularly check the lungs and find that they have signs of lung disease and seek medical advice.

In the current situation of severe pollution, when we complain about accountability, should we start from ourselves and start from scratch? In the daily life, we should pay more attention to environmental protection, otherwise we will suffer ourselves. As the soil fills the mountains, and the water becomes a source, the power of one person is still limited. The need to manage haze still needs to be joined by all of us. For the sake of our country's great rivers and mountains, and for the protection of the environment, we must not only stay in order to protect the environment. In words, we must use our actual actions to work hard.
