What are the unenvironmentally friendly phenomena around us?

All kinds of waste are the most obvious unenvironmentally friendly phenomena.

1. Indiscriminate felling and unscrupulous destruction of forest vegetation, resulting in a large amount of soil erosion, destruction of forest land, and destruction of biological chains.

2. Uncontrolled development of mines, resulting in landform changes, environmental pollution, and soil erosion. Waste of resources and non-renewable.

3. Sewage discharge, polluting surface water, such as amber and rivers, resulting in poor water quality and even affecting the function of water bodies; Polluting the soil, resulting in soil acidification, salinization, etc.

4. Fishing in the dry water, draining the pond water to catch fish, only for immediate interests, not for long-term planning.

5. Waste batteries are discarded, and the harm of old batteries is mainly concentrated in a small amount of heavy metals contained in them, such as lead, mercury, cadmium, etc. These toxic substances enter the human body through various ways, and it is difficult to eliminate them after long-term accumulation.

There are environmental damage around us: 1. Domestic garbage is not treated in time, that is, it is incinerated and buried in a moving position. 2. When farmers play pesticides, packaging bags, bottles, littering. 3. Burning straw in the wild. 4. Small factories are arranged in a disorderly manner.

Factories indiscriminately discharge wastewater, waste residue and waste gas, cut down and destroy forests at will, litter debris and garbage without sorting and disposal, dig up Chinese herbal medicines, destroy grassland vegetation and many others.

1. Air pollution: The polluted atmosphere released by daily life, the main components of which are carbon dioxide, chlorofluorocarbons, carbon monoxide, nitrogen oxides, sulfur dioxide, ozone, hydrocarbons, and dust and lead particles.

2. Chlorofluorocarbons (CFCs).: Mainly from air conditioning and refrigeration equipment that use freon, chlorofluorocarbon-containing aerosols (e.g. mousse), methyl chloroform or carbon tetrachloride dry cleaners, etc.

3. Carbon monoxide (CO):It mainly comes from automobile exhaust, coal burning and open burning of garbage.

4. Nitrogen oxides(NOx, including NO, NO2, NO3): Mainly from vehicle exhaust and coal-fired power plants.

5. Sulfur dioxide (SO2).: Mainly from coal-fired power plants and civil coal burning. Coal ash, soot and oil smoke mainly come from food stalls with coal stoves set up on the side of the road, kebab stalls, choking pot stir-frying, etc.

Common pollution phenomena

Dust: Mainly from the dust raised from the ground by sweeping the road and the driving of motor vehicles.

Lead pellets: Mainly from vehicle exhaust using leaded gasoline.

Ozone (O3, also known as photochemical oxidant): Mainly produced by the reaction of nitrogen oxides released by cars with oxygen in the presence of sunlight.

Hydrocarbons: Mainly from vehicle exhaust, fuel tank leaks, and gasoline volatilization.

Carbon dioxide (CO2): Mainly from the combustion of coal, oil and natural gas. The biggest emitters are thermal power plants, vehicles and other means of transportation.

1. Chemical pollutants. It mainly comes from inorganic pollutants such as ammonia, nitrogen oxides, sulfur oxides and organic pollutants such as formaldehyde, benzene and xylene, which are released or emitted from construction, decoration and furniture, cosmetics, kitchen combustion and indoor chemicals. At present, the main pollution in urban and rural public places and homes in China is chemical pollution, and common chemical harmful gases include formaldehyde, benzene, nitrogen and volatile organic compounds and other pollutants.

2. Radioactive contamination. Mainly from radon gas and decay progeny released from construction and decorative materials, but also from finished products made of stone, such as marble, sanitary ware, flooring, etc. Radon contamination of radioactive materials is currently the main problem of construction pollution in China, and some home decoration can also be generated, which has been included in the indoor environmental pollution control index of national civil construction projects.

3. Physical pollution. It mainly includes noise pollution, insufficient or too bright indoor lighting, electromagnetic radiation, ionizing radiation, etc., which cause harm to human health. In addition, some physical indicators in the indoor environment should not be called pollution, but they are also closely related to people's health.

For example, indoor temperature, humidity, fresh air volume, etc.

4. Biological contamination. Indoor air biological pollution is an important factor affecting indoor air quality, mainly including bacteria, fungi, pollen, viruses, organic components of organisms, etc. Indoor biological pollution is very harmful to human health and can cause various diseases, such as various respiratory infectious diseases, asthma, building syndrome, etc.

According to a survey conducted by the Indoor Environmental Monitoring Center, an average of about 50% of patients with atopic dermatitis caused by mites in the indoor air are affected.

5. Land pollution: The cleaning of garbage has become an important problem in major cities, and many of the tens of millions of tons of garbage every day cannot be incinerated or corrupted, such as plastic, rubber, glass and other human enemies.

There are garbage piles, sewage cross-flows, and plastic bags flying all over the sky.

There is wastewater, exhaust gas, waste residue that has been photographed.
