What measures do you think should be taken to reduce the harm of pm2.5?

Smog is an invisible killer, eroding our health bit by bit. Long-term exposure to particulate matter can lead to cardiovascular diseases, respiratory diseases and lung cancer. When the concentration of PM2.5 in the air is higher than 10 for a long time, the risk of death will increase. With the increase of 10, the total death risk increased by 4%, the death risk caused by heart and lung diseases increased by 6%, and the death risk caused by lung cancer increased by 8%. In addition, PM2.5 is easy to adsorb organic pollutants and heavy metals such as polycyclic aromatic hydrocarbons, which significantly increases the probability of carcinogenesis, teratogenesis and mutation.

Protect the environment for our health, strengthen exercise and take good protection when traveling. JD US imports Puweixin can reduce smog inhalation! I wish you a happy New Year! There are several reasons for the smog weather.

1. The main factor when the atmospheric pressure is low and the air does not flow. Because the air does not flow, the tiny particles in the air gather together and float in the air.

2. The ground is dusty and the air humidity is low. People and vehicles on the ground stir up dust.

3. Automobile exhaust is the main pollutant emission. In recent years, there are more and more cars in cities, and automobile exhaust is a factor of smog.

4. Secondary pollution produced by factories.

5. CO2 and other pollutants emitted by heating in winter.

Because smog will do harm to people's health:

1. 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.

2. Influence on 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.

3. Hazy 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.

4. In foggy days, due to the decrease of sunshine, children's ultraviolet radiation is insufficient, vitamin D production in the body is insufficient, and the absorption of calcium is greatly reduced, which will seriously cause rickets in infants and children, and slow down the growth and development of children.

5. Affect 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.

Therefore, go out as little as possible in foggy days. If you go out, you should be well protected. On this day, Puweixin, a cat imported from America, will help you reduce smog inhalation. I wish you the best of health! At present, there is no better way to control smog, and all people must participate in controlling smog.

"Everyone hates smog, but everyone is also the maker of smog.

"Controlling smog is not only a matter for the government and enterprises, but also requires the participation of the whole people." The sources of smog are mainly coal-fired power plants, steel mills and chemical plants.

Smog control is closely related to energy conservation and emission reduction, which is reflected in personal life. It is necessary to develop economical living habits, buy energy-saving household appliances as much as possible, and reduce the use of household appliances; Reflected in the production of enterprises, it is necessary to upgrade and improve the production process, consume less energy and use more clean energy; Reflected in traffic, it is necessary to drive less, promote the use of clean fuels such as natural gas, and improve automobile emission standards and fuel standards.

Strictly control the growth rate of automobiles.

Statistics show that construction dust, soil dust and road dust account for 28% of PM2.5 in Zhengzhou, and motor vehicle exhaust emissions account for 36%. Source carbon, biomass combustion source and secondary air pollutants are about 21%; About 15% comes from regional transmission.

"It can be seen that the large-scale growth of automobiles is one of the main reasons for the aggravation of haze weather. Although the media mainly focuses on cars, in fact, this is mainly because cars are better managed. At present, the implementation of automobile number limit has basically achieved all the measures that can be taken in this regard. In the deepening, cars can only be banned. Unfortunately, even if the car is banned, it is actually useless, and the smog that should come will still come. Because you can't stop generating electricity, can you? All the factories are closed?

The only feasible way is to control pollution emissions and strengthen investment in environmental protection measures. However, this will inevitably further increase the burden on enterprises. Now the profits of domestic industrial entities have basically been exploited to the extreme edge of the cliff. It is likely that a loss of profit of only one percentage point will probably lead to the collapse of the entire industrial base. This is a disaster ten million times worse than the legendary financial crisis. It will take some time to adjust the interests of the social industry, which will affect the whole body, so these things can only be done slowly.

Formulate emergency plans in the case of heavily polluted weather, and clarify the conditions and procedures for the start of emergency response and the division of responsibilities of government departments. For example, establish a prediction model of air quality pollution and release the pollution status to the public in time; During the haze weather, enterprises with heavy air pollution take measures to stop production and limit production according to specific conditions. In order to be healthy, increase the amount of exercise and do a good job in protective travel, you can wear Puweixin imported from Beijing * East America! I wish you a happy New Year!
