Every year, Beijing discards about 2.3 billion plastic bags, about 100 million disposable plastic tableware, and about 6.75 million square meters of waste agricultural film in the environment.

    People jokingly called it "the suburbs are white". As a new type of material, plastic products have the advantages of light weight, waterproof, durable, mature production technology and low cost, and are widely used all over the world and are increasing year by year. The growth rate of plastic packaging materials in the world market is higher than that of other packaging materials, and the average annual growth rate of plastic packaging materials in 1990-1995 is.

    The social hazards of white pollution:

    With the acceleration of people's life rhythm, social life is developing towards convenience and hygiene. In order to meet this demand, disposable styrofoam lunch boxes, plastic bags, chopsticks, water cups, etc. have begun to frequently enter people's daily lives. The emergence of these easy-to-use and low-cost packaging materials has brought a lot of convenience to people's lives.

    But on the other hand, these packaging materials are often discarded after use, resulting in"White pollution";It forms an environmental hazard and becomes a great environmental problem.

    1. According to the general elements of the imitation environment.

    Air pollution, water pollution, soil pollution, noise (sound) pollution, pesticide pollution, radiation pollution, heat pollution.

    2. Divide according to attributes.

    Overt pollution, hidden pollution.

    3. According to human activities.

    Industrial environmental pollution, urban environmental pollution, agricultural environmental pollution.

    4. According to the nature of environmental pollution caused by trembling wilds.

    Chemical, biological, physical (noise pollution.

    Radioactive pollution, electromagnetic wave pollution, etc.) solid waste pollution, liquid waste pollution, energy pollution.

    Land pollution: The clean-up of garbage has become a major 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.

    Marine pollution: mainly leakage from oil tankers and oil wells, pesticides and fertilizers used in farmland, sewage discharged from factories, acidic solutions flowing from mines; They pollute most of the oceans and lakes, and as a result, not only marine life.

    Victims, even birds and humans, can also be poisoned by eating these creatures.

    Air pollution: refers to the concentration of pollutants in the air that reaches or exceeds harmful levels, resulting in damage to ecosystems.

    and the normal survival and development of human beings, causing harm to people and living things. This is the most direct and serious one, and the main source is carbon monoxide released from factories, cars, power plants, etc.

    and hydrogen sulfide, etc., every day people are exposed to these dirty air, and people are infected with diseases of the respiratory organs or visual organs.

    Water pollution: refers to the phenomenon that the chemical, physical, biological or radioactive branch fiber pollution of the water body is changed due to the intervention of a certain substance, thereby affecting the effective use of water, endangering human health or damaging the ecological environment, and causing the deterioration of water quality.

    Noise pollution. It refers to the phenomenon that the environmental noise generated exceeds the environmental noise emission standards stipulated by the state and interferes with the normal work, study and life of others.

    What is white pollution.

    It refers to the phenomenon that all kinds of domestic plastic products made of polystyrene, polypropylene, polyvinyl chloride and other polymer compounds are discarded as solid waste after use, and are difficult to degrade due to random littering, resulting in serious pollution of the urban environment.

    The main white pollution is food packaging, styrofoam filled packaging, fast food boxes, agricultural mulch films, etc.

    White pollution is a unique environmental pollution in China's cities, a large number of discarded plastic products can be seen everywhere in various public places, they come from nature, made by human beings, and are not easy to be absorbed by nature when they are ultimately attributed to nature, thus affecting the ecological environment of nature. From the perspective of resource conservation, because plastic products are mainly facing depleted petroleum resources, they should be as much as possible, but because the production cost of re-production at this stage is much higher than the direct production cost, it is difficult to do so under the current market economy conditions.

    Hazards of White Pollution:

    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 fluoron. 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 soil: Non-degradable plastic products entering the soil will affect the matter in the soil, heat transfer and microbial growth, 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.

    Damage the land structure, hinder the absorption of water by plants and the growth of roots, and affect crop harvest.
