What are the dangers of white pollution? What can we do to reduce this pollution?

The so-called "white pollution" is an image of people polluting the environment with plastic waste. It refers to all kinds of domestic plastic products made of polymer compounds such as polyethylene, polypropylene, polyvinyl chloride and so on are discarded as solid waste after use, and are littered at will and difficult to degrade and dispose of, so as to cause serious pollution of the urban environment.

The amount of plastic waste consumed and discarded in the city is staggering. Among the "white garbage", the most obvious pollution, the most headache, and the strongest reaction of the masses are those waste plastic packaging bags and disposable plastic fast tableware all over the city streets. According to the statistics of relevant departments, taking disposable plastic foam fast food as an example, China's annual consumption reaches 400 million to 700 million, of which 20 million to 40 million in Tianjin.

How to prevent and control "white pollution" and protect the urban ecological environment? Relevant experts put forward the following prevention and control measures:

1. Put the prevention and control of "white pollution" on the track of legalization. At present, the state has enacted special legislation on this issue, and the broad masses hope that the relevant laws and regulations will be promulgated as soon as possible.

2. Formulate medium- and long-term governance plans. It is an inevitable trend for non-degradable plastic products to "abdicate" from urban life. This requires people to have a sense of urgency and prepare for two things: one is to find a way; The second is to set a timetable.

Relevant departments should set tasks and clarify responsibilities at the three levels of pollution, economic pollution reduction, and pollution prevention, so that the treatment of "white pollution" can be carried out in a step-by-step, targeted, and time-bound manner.

3. Pay attention to the prevention and control of "white pollution"; scientific research and technical research. Vigorously; Support the development, production, sales and use of degradable "green" alternative products.

Fourth, enhance the awareness of environmental sanitation of the whole people, and take the prevention and control of "white pollution" as the key content of the construction of the "two civilizations" and the comprehensive improvement of the urban environment.

Fifth, pay close attention to the source of pollution control, and implement the principle of reduction, harmlessness, and resource saving, and recycling. On the one hand, it is necessary to suppress the amount of "white pollution", and on the other hand, emphasize the use of "white garbage".

Reduce the production of plastic bags! Plenty of cloth bags. If you don't produce, you can't pollute naturally.

The so-called "white pollution" is a figurative term for the phenomenon of waste plastics polluting the environment. In nature, there are almost no microorganisms that can use plastic as nutrients. Plastic waste stays in nature for a long time, even up to 500 years.

1. Visual pollution, potential hazards, biological hazards, and fire hazards.

2. Biological hazards: white garbage may become a nest for pests, which can provide food, habitat and breeding places for rats, birds, mosquitoes and flies, and the residues in it are often the source of infectious diseases.

3. Fire hazards: white garbage is combustible, which will produce methane and other combustible gas in the process of natural stacking, and it is easy to cause disasters in case of open flame or spontaneous combustion.

1. Encroachment on too much land. Plastic waste stays in nature for a long time, generally up to 200-400 years, and some up to 500 years.

2. Polluting the air. Plastics, paper scraps, and dust fly in the wind and can cause air pollution problems.

3. Polluting water bodies. Plastic bottles and lunch boxes floating on the surface of rivers and seawaters, plastic bags and bread wrap hanging from branches above the water not only cause environmental pollution, but also harm the health of animals if they accidentally eat white garbage, and even starve to death because they cannot digest it in the digestive tract.

4. Fire hazards. Almost all white garbage is combustible, and methane and other combustible gas will be produced in the natural stacking process, and fire accidents caused by open flames or spontaneous combustion continue to occur, often causing heavy losses.

5. Increase the risk of disease infection. White litter can be a nest for pests, providing food, habitat and breeding for rats, birds, mosquitoes and flies, and the residue is often a source of infectious diseases.

6. Difficult to degrade. After waste plastic packaging enters the environment, it is difficult to degrade, causing long-term and deep-seated ecological and environmental problems. First of all, waste plastic packaging is mixed in the soil, which affects the absorption of nutrients and water by crops, which will lead to a reduction in crop yield. Secondly, if the livestock eats the plastic film, it will cause digestive diseases and even death of the livestock.

1. Harm to the human body: the use of disposable foamed plastic tableware may cause cancer, and have suppressed immunity, reproductive toxicity and endocrine toxicity. The raw material for the production of foamed plastic products is polystyrene, and the foaming agent used is Freon.

In addition to the pollution problem, it also contains "dioxins" and other toxic substances. When the temperature exceeds 65, some toxins and "dioxins" will precipitate and seep into food, which will cause damage to the liver, kidneys, reproductive system and central nervous system. Eating hot food in a foamy lunch box is equivalent to eating toxins such as dioxins.

2. Harm to the soil: non-degradable plastic products entering the soil will affect the material and heat transfer and microbial growth in the soil, and change the characteristics of the soil. After entering the landfill as domestic garbage or scattered in the field into the soil, waste plastic products are mixed in the soil and affect the absorption of nutrients and water by crops, resulting in reduced crop yields.

These include mulch film that remains in the soil after use. After the plastic film used in the field is aged, it will be broken and left in the field, and will not decompose and decay. Destroying the land structure, hindering the water absorption and root growth of plants, and affecting crop harvest.

According to the survey, if each mu contains kilograms of residual film, it can reduce the yield of corn by 11% and 23%, and the yield of wheat by 9% and 16%, and this pollution is difficult to eliminate.

3. Harm to animals: waste plastic bags discarded on the ground and water are easy to be swallowed by fish, horses, cows, sheep and other animals as food, and plastic bags cannot be digested in the animal's stomach, resulting in damage and death of animal gastrointestinal muscles. Some of the antelopes and giraffes in the Beijing Zoo have accidentally eaten plastic bags and become ill, and the "national treasure" giant panda has also died due to eating plastic bags.

White pollution usually refers to the phenomenon that various domestic plastic products are discarded as solid waste after use, which is difficult to degrade and treat, resulting in serious pollution of the urban environment, which is a term for people to pollute the environment by plastic waste. The most important white pollution is waste plastic packaging bags, disposable plastic fast food boxes, etc.

White pollution refers to plastic bag pollution.

Generally refers to plastic pollution, because it is very difficult to degrade and regenerate, so it is very polluting to the environment.

Reducing white pollution can be done through efforts to reduce white pollution from source manufacturers, to user merchants and consumers, to treatment manufacturers. Production enterprises with more production of degradable materials, businesses and consumers to save, the general public to pay attention to environmental protection, treatment of manufacturers classification and so on.

White pollution refers to garbage pollution, mainly plastic bags, etc., because plastics are mostly white, so they are white pollution.

Plastic bag pollution, also known as white pollution.
