Social investigation report on air pollution

Lead: How serious is air pollution? I have compiled the social investigation report of air pollution, welcome to refer to it!

Report on Social Investigation of Air Pollution 1 I. Proposing the Problems

The original blue sky turned white. Even during the day, it's only 20? The visibility of 30 meters greatly increased the accident rate of cars. After the rain, the windshield of the car was covered with mud, and even the glass was covered with dust. In the street, you can often see some people hiding their faces behind thick white masks. Every time the cleaner sweeps the floor, he can see a thick layer of sand rising from the ground and falling from mid-air. The respiratory department of the hospital is crowded with people? What caused these situations to happen? What harm does this happen to us? How should this situation be improved?

Second, research methods.

1, find relevant data online to understand the relevant situation.

2. Topographic photography

Third, data collation.

(1) Statistical results of API days and percentage of air pollution index in counties and cities in XX.

Judging from the above table, the environment in zhenhai district is far worse than that in Xiangshan County. They are also coastal towns. Why is there such a difference? In fact, it is not difficult to find that Xiangshan's industry is not as developed as that around Zhenhai, and the number of cars is not as large as that around Zhenhai, indicating that the main causes of pollution come from industry and transportation.

(1), industry: The pollution discharged into the atmosphere by industrial production should not be underestimated. The pollutants in the industrial atmosphere include soot, sulfur oxides, nitrogen oxides, organic compounds, halides, carbon compounds and so on. The discharge of a large number of untreated water, gas, slag and other harmful wastes in industrial production will seriously destroy the agricultural ecological balance and natural resources and cause great harm to the development of agricultural production; Second, environmental pollution and public hazards are rampant, which directly endanger the health of the broad masses of people, seriously undermine the agricultural ecological balance, and do great harm to the development of agricultural production.

Zhenhai ancient town originally had a good living environment. Since the introduction of chemical projects, the air quality in Zhenhai has gradually deteriorated with 65.438+0.95 billion cubic meters of toxic gas every year, resulting in a large number of people migrating to the urban and suburban areas of Ningbo. However, from the chemical incidents in previous years to the LG chemical leakage incident last year, there are several undisclosed incidents such as rollover of chemical trucks, which have great hidden dangers to people's lives. People who have lived in the old city for a long time are numb to the chemical smell in the air they breathe every day, but the new people in Zhenhai say? Why is there an odor in the air of Zhenhai? .

(2) The hourly traffic flow is 7: 00-8: 00, 30 vehicles per minute, 9: 00-5: 00, 5- 10, 5: 30-6: 30, 20-30, and the air quality is 4 hours at night.

(2) Transportation: Cars, trains, planes and ships are the main means of transportation at present, and the waste gas produced by burning coal or oil is also an important pollutant. Especially, the cars in cities are large and concentrated, and the pollutants emitted by exhaust gas can directly hit people's respiratory organs, which has caused serious air pollution in cities and has become one of the main sources of air pollution in big cities. The exhaust gas emitted by automobiles mainly includes carbon monoxide, sulfur dioxide, nitrogen oxides and hydrocarbons, and the first three substances are very harmful.

The benefits of chemical industry in Zhenhai are objective, so the quality of life of Zhenhai families is relatively good, and most families have 1? Two cars, the exhaust gas of each car contains hydrocarbons and nitrogen oxides.

Compounds, carbon monoxide, particles, etc. When the rush hour arrives, there is a heavy traffic jam on the road. But the slower the speed, the more emissions. Therefore, transportation is another important source of air pollution.

If these air pollution are not controlled, the ozone hole on the earth will become bigger and bigger. But the ozone hole will get bigger and bigger, which will aggravate global warming, accelerate the melting of icebergs at the poles and make animals there lose their homes. Moreover, these pollution sources have great direct harm to people. Without the protection of ozone layer, the sunlight will be enhanced, which will increase the risk of skin cancer. But those inhalable particles can also infect people's respiratory tract. Therefore, air pollution is not only harmful to nature, but also harmful to human beings themselves.

Four. conclusion

Therefore, we can know that the cause of this kind of weather is the source of pollution gas and pollutants produced by coal stoves used in chemical areas, vehicles and rural households, which is very harmful to human beings. In protecting the environment, we can start with raising people's awareness of environmental protection, so that everyone can have a general understanding of our environment first, and then let everyone start from themselves and protect the environment with their own practical actions, so as to achieve the goal of peace between people and the environment.

(A) to strengthen environmental awareness

Strengthening environmental awareness can provide spiritual motivation and public opinion support for the implementation of environmental protection work; Conducive to the in-depth implementation of environmental protection policies; With the active participation of all staff, the problems encountered in environmental protection work will continue to decrease and weaken. Public supervision is conducive to the smooth formulation and implementation of environmental protection policies and work.

1, to strengthen community publicity, we can survive by distributing leaflets, so that people in our community have a sense of protecting the environment.

2. When necessary, we should also ask the government to make a reasonable plan for the industrial zone so that people can live in a green environment as much as possible.

When we see that the behavior of people around us will cause some damage to our environment, we should try our best to stop these bad behaviors.

Our government should also take some necessary measures to limit the carbon dioxide emissions of cities, such as limiting the driving of single and even cars.

(B), starting from the self

Although people can't avoid carbon emissions, they can reduce them. Everyone can't live? Zero carbon? In our life, when resources are scarce, what we should do is to meet people's basic needs with limited resources and limit extravagance and waste. At the same time, development? Low carbon life? Concept, under the optional and replaceable conditions, the natural, environmentally friendly and healthy lifestyle is preferred.

1. In order to reduce air pollution during holidays, we can drive less and choose to travel by bike, which not only protects our environment, but also exercises our bodies. Isn't it killing two birds with one stone?

During the Spring Festival, setting off fireworks has become a hot topic among netizens recently. In my opinion, although it is festive to set off fireworks and firecrackers in the New Year, a lot of smoke and sulfur dioxide will be released after setting off fireworks and firecrackers, which will seriously pollute the air. To this end, I hope everyone will take care of the environment and put less or no fireworks.

3. Afforestation in dense forests can reduce wind speed and large dust carried in the air; Therefore, we should not just plant a few trees symbolically on Arbor Day, but should have the idea of planting trees in peacetime and persistently and gradually alleviate the desertification of the land.

Social investigation report on air pollution II. Propose a question

Air pollution is a great threat to our life. What caused the pollution? What kind of solution will there be? I did a survey.

Second, the survey method

1. Pay attention to the reports about air pollution in news broadcast, evening paper and weather forecast, record them selectively and cut them out.

2. Actual investigation, feeling the difference of polluted air to human body.

3. What are air pollutants?

Three. Investigation and data collation

Environmental pollution and climate change

Exhaust gas, carbon black and dust produced by factories, power stations and motor vehicles are discharged into the air, which will cause air pollution. Polluted air is not only harmful to human body, but also the waste gas in the air will form acid rain, which will cause damage to trees, creatures and buildings in rivers and lakes. In addition, many waste gases will seriously damage the ozone layer, leading to the increase of many harmful substances in the atmosphere.

Actual investigation, experience

Influence of air pollution on human body

Narrow vision, tears, eye inflammation. Smell peculiar smell, chest tightness, airway inflammation, dyspnea, pulmonary edema, rapid suffocation and death.

Four. conclusion

First, the main source of air pollution

(1) Productive pollution is the main source of air pollution, including: ① the combustion of fuel, mainly a large number of harmful substances emitted during the combustion of coal and oil, such as soot and sulfur dioxide emitted from coal combustion; Burning oil can emit sulfur dioxide and carbon monoxide; (2) Coal-fired power plants, steel plants, petrochemical plants and cement plants are the most serious air pollution sources. ③ Dust and fog drops produced by spraying pesticides in agricultural production.

(2) Harmful gases such as soot and sulfur dioxide produced by burning coal in domestic stoves and heating boilers.

(3) Traffic pollution refers to the tail gas emitted by cars, trains, ships and airplanes, in which the harmful tail gas emitted by cars is closest to the breathing zone and can be directly inhaled by people, and its pollutants are mainly nitrogen oxides, hydrocarbons, carbon monoxide and lead dust.

Second, how to protect environmental sanitation?

In order to protect the air from pollution and make everyone happy and healthy, I suggest:

1. We should educate everyone about the importance of caring for the environment, instead of just making money and ignoring environmental pollution. Everyone should consciously maintain environmental sanitation.

The government should do a good job in environmental protection, and order those enterprises that pollute the environment to find ways to eliminate or at least reduce pollution, otherwise they can't be allowed to produce. The government should also be willing to spend some money on some projects to purify the environment, instead of just paying fines. Some factories that seriously pollute the environment can be moved to the countryside because there are many trees there, which can purify the air.

We should plant more trees and do more urban greening, because trees and flowers can purify the air.
