What are the main factors of environmental pollution

The building itself, the decoration and the furniture.

The pollution caused by the building itself is mainly ammonia. The concrete admixtures and antifreeze used in building construction contain a large number of ammonia substances, which are reduced to ammonia gas in the wall with the change of environmental factors such as temperature and humidity, which is slowly released from the wall, resulting in ammonia pollution in the indoor air. Radon released from building materials can also cause high levels of radioactive material in the room.

Decoration pollution mainly comes from the use of plywood, blockboard, MDF and particleboard and other man-made boards, because the adhesive used in these materials is formaldehyde as the main component of urea-formaldehyde resin, and the residual and non-reactive aldehydes in the board will be gradually released to the surrounding environment. Other types of decorative materials that contain formaldehyde and may be emitted to the outside world include wall coverings, wallpaper, chemical fiber carpets, styrofoam, paints and coatings, etc.

Furniture pollution is mainly caused by the use of substandard man-made panels by some manufacturers. At the same time, some soft furniture such as various sofas, especially fabric sofas and mattresses, will also emit various harmful gases. According to experts, the pollution of soft furniture such as fabric sofas is mainly due to the use of benzene-containing spraying glue.

Buying back the furniture is equivalent to spending money on a small exhaust emission station.

Environmental pollution refers to the phenomenon that due to human factors, pollutant substances enter the environment, so that the composition and state of the natural environment have changed, the structure and function have been destroyed, the environmental quality has deteriorated, the ecosystem has been destroyed, and the production and life of human beings have been harmed. Specifically, environmental pollution refers to harmful substances, mainly industrial"Three wastes"Pollution of the atmosphere, water, soil and organisms (exhaust gases, waste water and waste residues). Environmental pollution includes air pollution, water pollution, soil pollution, biological pollution and other pollution caused by substances and pollution caused by physical factors such as noise pollution, thermal pollution, radioactive pollution or electromagnetic radiation pollution.

Some heavy and light industries such as fertilizer factories, as well as food processing, paper industry, coal mining processing, petroleum refining, etc., are more likely to pollute the environment.

The human factor, humans don't want to destroy the environment and it's fineImproper wastewater treatment in factories, emissions from vehicle exhaust, and indiscriminate deforestation.

Solution: Introduce new environmentally friendly materials and plant more treesIndustrial wastewater, exhaust gas, waste residue, automobile exhaust, freon, indiscriminate cutting of vegetation and so on will cause pollution.

Most of it is caused by human greed.

Due to the lack of anticipation and prevention of the negative impact of highly developed industry, it has led to three major crises around the world: resource shortage, environmental pollution, and ecological destruction. Environmental pollution refers to the act of natural or man-made destruction, adding a certain substance to the environment and exceeding the self-purification ability of the environment and causing harm.

The phenomenon that the composition or state of the environment changes due to human factors, and the quality of the environment declines, thereby disturbing and destroying the normal production and living conditions of the ecosystem and human beings.

4. According to the nature of environmental pollution: (1) chemical pollution; (2) Biological pollution; (3) Physical pollution; (4) Solid waste pollution; (5) Liquid waste pollution; (6) Energy pollution; (7) Light pollution.

3. What are the causes of environmental pollution?

1) Waste smoke, waste gas, waste water, waste residue and noise discharged from the factory;

2) Waste smoke, exhaust gas, noise, dirty water and garbage discharged from people's lives;

3) Exhaust gas and noise emitted by vehicles;

4) Water flowing out after irrigation of farmland with a large number of chemical fertilizers, pesticides, herbicides and other chemicals;

5) Mine wastewater and waste residue;

6) Machine noise, electromagnetic radiation, carbon dioxide pollution.

Legal basis: Interpretation on Several Issues Concerning the Application of Law in the Handling of Criminal Cases of Environmental Pollution" makes new provisions on the standards for conviction and sentencing of environmental pollution crimes, so as to severely punish and prevent environmental pollution. According to the Interpretation, causing serious injuries to one or more persons or minor injuries to three or more persons constitutes "serious environmental pollution" and will be subject to criminal liability for the crime of polluting the environment.

Article 9: [Rules for the Application of Legal Provisions]Where a party's illegal conduct violates two or more environmental laws, regulations, or rules at the same time, the law, regulation, or rule with a higher level of effectiveness shall apply; Where the level of effectiveness is the same, the provisions with heavier penalties may be applied.

Water pollution caused by various types of domestic sewage and industrial and agricultural wastewater. Air pollution caused by industrial soot exhaust gases and exhaust gases produced by vehicles. All kinds of noise pollution.

Pollution from various residues, heavy metals and waste. Soil erosion and deterioration of the ecological environment caused by overgrazing and deforestation. Stratum subsidence and soil structure damage caused by overexploitation of various underground resources.

1. Water pollution caused by all kinds of domestic sewage and industrial and agricultural wastewater.

2. Air pollution caused by industrial smoke and exhaust gases and exhaust gases generated by vehicles.

3. All kinds of noise pollution.

4. Pollution caused by various residues, heavy metals and wastes.

5. Soil erosion and deterioration of the ecological environment caused by overgrazing and indiscriminate deforestation.

6. Stratum collapse and soil structure damage caused by overexploitation of various underground resources.

1. Sandstorms.

Causes: Nature: drought, high winds, rising air currents; Anthropogenic: Destruction of vegetation.

Distribution: Northwest China, North China (spring).

Hazards: Reduced atmospheric visibility, endangering health, transportation, lakes, reservoirs, agricultural production, villages, cities.

Measures: Biological measures: protection of existing vegetation and afforestation; Engineering measures: cross-basin water transfer, water diversion for irrigation; Management measures: returning farmland to forests and pastures.

2. Desertification.

Causes: Nature: arid climate, degraded vegetation, intensified physical weathering, strong winds; Anthropogenic: deforestation, over-reclamation, overgrazing.

Distribution: Northwest, North China, West Northeast China.

Harm: The ecological environment has deteriorated, and the area of cultivated land, forest land and grassland has decreased.

Measures: Biological measures: protection of existing vegetation and afforestation; Engineering measures: cross-basin water transfer, water diversion for irrigation; Management measures: return farmland to forests and grasslands.

3. Eutrophication of water bodies.

Causes: A large amount of waste liquid containing N and P is discharged into ponds, lakes and rivers.

Distribution: suburbs of towns, rivers, lakes and seas.

Hazards: Lack of oxygen in the water affects the survival of aquatic organisms.

Measures: Reduce the use of fertilizers and pesticides; the use of chemical fertilizers and pesticides with low retention; Industrial wastewater and domestic sewage are discharged into rivers, lakes and seas after treatment.

There are generally three factors that cause environmental pollution: chemical, physical and biological factors.

1. Chemical factors: certain elemental elements or their organic and inorganic compounds enter the environment and are poisoned by human contact. Such as aluminum, arsenic, mercury, helium, phenol, benzopyrene and various pesticides.

2. Physical factors: such as dust, plastics, radioactive substances, static electricity, electronic dust, radon, ozone and noise, etc., can directly and indirectly cause harm to the human body.

3. Biological factors: such as viruses, bacteria, fungi and other genogens that have always belonged to humans.

Pollution sources or pollutants formed by the above three factors can directly or indirectly pollute the environment and affect human health. Not only for the individual, but also for future generations.

1) Waste smoke, waste gas, waste water, waste residue and noise discharged from the factory;

2) Waste smoke, exhaust gas, noise, dirty water and garbage discharged from people's lives;

3) Exhaust gases and noise emitted from vehicles (all fuel vehicles, ships, airplanes, etc.);

4) Water flowing out after irrigation of farmland with a large number of chemical fertilizers, pesticides, herbicides and other chemicals;

5) Mine wastewater and waste residue;

6) Machine noise, electromagnetic radiation, carbon dioxide pollution.

The main pollutants in the air are sulfur dioxide, nitrogen oxides, particulate pollutants, and acid rain. The concentration and toxicity of pollutants naturally decrease, a phenomenon called environmental self-purification.

If the emitted substances exceed the self-purification capacity of the environment, the quality of the environment will undergo adverse changes, endangering human health and survival, which will cause environmental pollution.
