New year's eve health system

Will the fireworks pollute the air? Fireworks produce gases such as sulfur dioxide, nitric oxide and nitrogen dioxide, and are invisible "killers". When the smoke is filled, these gases are harmful to our respiratory system, nervous system and cardiovascular system, and also have a * * * effect on our eyes. Others will contribute to the occurrence or development of some diseases. According to the monitoring of the air automatic station of Fuyang Environmental Monitoring Station, when a large number of firecrackers were set off during the Spring Festival, the concentrations of sulfur dioxide and carbon monoxide in the air of Fuyang City increased significantly, and the nitrogen dioxide, sulfur dioxide and inhalable particles in the air all exceeded the national standards. These pollutants exceed the standard, which means that the atmospheric environment has been polluted, and these increased pollutants are also harmful to health. In addition, noise pollution. The explosion of fireworks and firecrackers on New Year's Eve is like thunder. Noisy people often find it difficult to fall asleep on New Year's Eve. Over the years, this seems to have become a practice in China. According to the monitoring of firecrackers pollution in Wuhan, Shanghai, Beijing and other big cities 10 during the Spring Festival, it is found that the noise in the area where firecrackers are set off is as high as 135 dB, far exceeding people's hearing range and tolerance limit. According to the monitoring data of Beijing environmental protection monitoring department, the maximum noise on New Year's Eve can reach 102.5 to 125 decibels, which seriously exceeds the national noise standard of 45 decibels at night. After the implementation of the ban, the noise monitoring results of New Year's Eve in eight suburban counties showed that the noise pollution decreased significantly. It is understood that the noise that people can accept at night should not exceed 45 decibels, which is equivalent to the sound of frogs. Moreover, high-intensity noise is very harmful to patients with cardiovascular and cerebrovascular diseases. Every decibel of noise increases, the incidence of hypertension increases accordingly. During the Spring Festival, the adverse effects of high-intensity, high-density and long-lasting noise on health can be imagined. It is reported that there are cases of severe hearing loss, explosive deafness and hearing impairment caused by setting off firecrackers almost every year in China. Fireworks and firecrackers will also produce solid waste pollution. According to the sanitation department of Fuyang City, after setting off firecrackers during the Spring Festival, the amount of garbage will increase exponentially, which will increase the burden on sanitation workers during the festival. Paper scraps and smoke can be seen everywhere, which seriously affects environmental sanitation. Setting off fireworks will also pollute the water source. The "cannon fodder" garbage should be released. If fireworks and firecrackers are set off when it rains or snows, pollutants will be discharged into the surrounding water and pollute the surrounding rivers. Fireworks and firecrackers not only bring us joy, but also leave us a lot of toxic and harmful substances, which not only have safety hazards, but also have pollution hazards and health hazards. A series of chemical reactions occur during the combustion of fireworks and firecrackers, which release a large number of carbon monoxide, sulfur dioxide, sulfur trioxide, nitrogen oxides and various metal and nonmetal oxides, and produce a large number of smoke particles. Fireworks and firecrackers exploded on the eve of the Spring Festival in Dandong City, Liaoning Province 1990, which was equivalent to a major pollution accident. According to the monitoring by the scientific research personnel of the Environmental Protection Monitoring Station from 23: 40 on February 29th to the first day of the first month 10, the average value of total suspended particles in the whole city is 3.6 1mg/m3, which is 2.6 times higher than the national secondary standard of Atmospheric Environmental Quality (the daily average value of the secondary standard is 0.30mg/m3, and it is1.00 at any time). At the same time, the noise pollution caused is also quite serious. When the concentration of harmful substances such as sulfur dioxide and sulfur trioxide in the air exceeds the allowable value, it will cause damage to respiratory mucosa and lung tissue, cause or induce diseases such as bronchitis, tracheitis, pneumonia, emphysema, etc., which can combine with hemoglobin in human body and appear symptoms of hypoxia and poisoning. The nitrogen and oxygen compounds in the smoke produced by the combustion of fireworks and firecrackers mainly include nitrous oxide (N2O), nitric oxide (NO), nitrogen dioxide (NO2) and nitrogen trioxide (N2O3). Among them, nitric oxide and nitrogen dioxide are the main components, which are expressed as nitrogen oxides (nitrogen oxides). When there are nitrogen oxides and hydrocarbons in the air, photochemical reactions will occur after being irradiated by sunlight and ultraviolet rays, resulting in a photochemical smog, which is a toxic secondary pollutant, causing pathological changes and headaches. People exposed to too high nitrogen oxides for a long time may die. Therefore, the indoor nitrogen oxide content should not exceed 5 mg/m3. NO2 is four times as toxic as NO, which will lead to lung injury and even pulmonary edema. Chronic poisoning can cause trachea and lung diseases. Inhalation of NO will lead to the formation of denatured hemoglobin and affect the central nervous system. The concentration of nitrogen oxides in animals is about 1.0 mg/m3, and that in patients is about 0.2 mg/m3. According to the national environmental quality standards, the average concentration in residential areas is below 0. 10 mg/m3, and the average annual concentration is below 0.05 mg/m3.

Will lighting tobacco and flowers in the Olympic Games not pollute the air? It is said that "the fireworks used in the opening ceremony have special functions such as low pollution and flame retardant"

But I believe there will still be pollution ... because the quantity is very large. ...

If the rainfall on the opening day exceeds this figure, the fireworks display may be cancelled. ...

Will soil pollution pollute air and water? If there is groundwater, it will stink and the molecules will always move irregularly.

The United States imported Puweixin Tmall to effectively prevent smog and go out for protection.

Is that paint or smoke? Will it pollute the air? That's not a flag, it's a cigarette. It won't pollute the air, dear!

Will burning straw seriously pollute the air? Of course, there are many harmful substances there. Besides, the environmental protection department now prohibits burning straw. Now you should go out less. When going out, you should wear a Puwei German mask imported from the United States, which has good filterability. I wish you happiness and hope to adopt it.

What substance emits a lot of white smoke when it burns, but it won't pollute the air. As a white solid, white smoke will definitely pollute the air, so such a substance does not exist.

Will the harm of waste oil in the air pollute the air? Theoretically, it is.

However, there are strict standards for making a flight plan and how much fuel to add before taking off. Only under unexpected circumstances will we consider giving up fuel, such as excessive fuel in emergency standby, or fuel valve failure can not ensure the weight balance of fuel tanks on both sides. In addition, fuel economy is also one of the indicators for many airlines to assess pilots, and no one will dump fuel indiscriminately.

Will fireworks pollute the air? How serious is it? Are you really asking, or are you just talking nonsense?

If you really ask, you can check the total amount of raw materials (sulfur, dynamite, etc. ) Through the statistics of fireworks and bamboo production in each province by the administrative department for industry and commerce, the total amount of gas produced can be calculated.

Pay attention to subtract the part exported abroad.

Will smoking pollute the air? Impact on weather and climate: The impact of air pollutants on weather and climate is very significant, which can be explained from the following aspects:

(1) Reduce the amount of solar radiation reaching the ground: A large number of smoke particles discharged into the atmosphere by factories, power stations, automobiles, household heating devices, etc. make the air very turbid, which blocks the sunlight and reduces the amount of solar radiation reaching the ground. According to observation and statistics, in the days when smoke and dust are not scattered in large industrial cities, the direct sunlight on the ground is reduced by nearly 40% compared with the days without smoke and dust. In cities with serious air pollution, people, animals and plants will be stunted due to lack of sunshine every day.

(2) Increase atmospheric precipitation: Many particles emitted by large industrial cities have the function of water vapor condensation nuclei. Therefore, when there are other precipitation conditions in the atmosphere, there will be precipitation weather. In the downwind areas of large industrial cities, there is more precipitation.

③ Acid rain: Sometimes, the rain falling from the sky contains sulfuric acid. This kind of acid rain is the oxidation of sulfur dioxide, a pollutant in the atmosphere, to form sulfuric acid, which falls with the precipitation in nature. Sulfuric acid rain can destroy large areas of forests and crops, corrode and destroy paper products, textiles and leather products, degrade metal antirust coatings and reduce their protective effects, and also corrode and pollute buildings.

(4) Raise the atmospheric temperature: Over large industrial cities, the air temperature near the ground is higher than that in the surrounding suburbs due to a large amount of waste heat discharged into the air. This phenomenon is called "heat island effect" in meteorology.

⑤ Impact on global climate: In recent years, people have gradually noticed the impact of air pollution on global climate change. After research, people think that carbon dioxide plays an important role in various air pollutants that may cause climate change. About 50% of the carbon dioxide released into the atmosphere by countless chimneys and other exhaust pipes on the earth remains in the atmosphere. Carbon dioxide can absorb long-wave radiation on the ground and raise the air temperature near the ground, which is the so-called "greenhouse effect". It is roughly estimated that the near-surface temperature will increase by 0.5 ~ 2℃ for every 25% increase of carbon dioxide content in the atmosphere. If 100% is increased, the near-surface temperature can be increased by 1.5 ~ 6℃. Some experts believe that the carbon dioxide content in the atmosphere will increase at the current rate, which will melt the ice in the North and South poles in a few years, leading to global climate anomalies. I hope it will help your problem. If you are satisfied, please use o (∩ _ ∩) o. ...

Will Supor Electronics Factory pollute the air? There is pollution. There are many heavy metals in electronic components, which will cause water pollution and possibly air pollution (* * * gas). Moreover, the high-temperature tin furnace in the electronics factory will release lead vapor (the tin bar itself contains lead), which will pollute the surrounding environment and endanger the health of workers. Have an impact on the environment, and have an impact on the environment and health. Puweixin Tomcat imported from the United States can effectively prevent smog and go out as a protective mask. The dust blocking efficiency is based on its blocking efficiency against fine dust, especially respiratory dust below 2.5 microns. Because dust with this particle size can directly enter alveoli, it has the greatest impact on human health. Gauze mask, its dustproof principle is mechanical filtration, that is, when dust collides with gauze, some large particles of dust are blocked in emery cloth through layers of barriers. For some fine dust, especially dust smaller than 2.5 microns, it will enter the respiratory system through the mesh of gauze. Dust mask, its filter material is composed of activated carbon fiber felt pad or non-woven fabric, and those inhalable dust smaller than 2.5 microns pass through this filter material.
