When the temperature reaches 65 °C, the harmful substances in the disposable foamed plastic tableware will penetrate into the food, causing damage to the human liver, kidney and central nervous system. Therefore, on April 23, 2001, the State Economic and Trade Commission Issued "Emergency Notice on Immediately Stopping Production of Disposable Foamed Plastic Tableware", requesting to stop production of disposable foam plastic lunch boxes. The General Office of the State Council issued the "Notice on Restricting Production, Sales and Use of Plastic Shopping Bags" (hereinafter referred to as 'Limited plastic order'), from June 1, 2008, it is prohibited to produce, sell, use ultra-thin plastic shopping bags with thickness less than 0.025 mm, and prohibit supermarkets, shopping malls, marketplaces and other retail places. Free plastic shopping bags.
We all know that the potential hazards of white pollution are multifaceted.
1. Disposable foam plastic lunch boxes and plastic bags contain food that seriously affects our health. The ultra-thin plastic bags we use to hold food are usually polyvinyl chloride plastic. As early as forty years ago, people discovered polychlorinated chlorine. Vinyl chloride monomer remains in vinyl plastic. When people are exposed to vinyl chloride, wrists, finger edema, hardening of the skin, etc., splenomegaly, liver damage and other symptoms may occur. In 1975, the United States prohibited the use of poly Vinyl chloride plastic packaging food and beverages. In our country, almost all of the ultra-thin plastic bags we use come from the recycling of waste plastics. They are produced by small enterprises or family workshops. CCTV's "News Investigation" program group has made unannounced visits. The production of plastic bags, the raw materials used in these production plants are discarded plastic barrels, pots, disposable syringes, etc. In production, the raw materials are first pulverized into plastic particles by mechanical means, and the plastic particles are placed in a pool for cleaning (name Disinfecting), taken out to dry, and then mechanically pressed it into a film, made into various plastic bags. The reporter asked the boss, this plastic bag is used to hold food, is harmful to the human body, the boss does not hide I admit that this kind of film is not sterilized, it is definitely harmful to the body. He himself never used this kind of plastic bag. Every time I eat, many students use plastic bags to fill the food. They don't know that this behavior not only harms the environment, Also endanger your body.
2, the soil environment deteriorates, seriously affecting the growth of crops. The plastic products currently used in China are generally non-degradable, and their molecular weight is more than 20,000. Only when the molecular weight drops below 2000, can they be used by microorganisms in nature. The process takes at least 200 years. The waste agricultural film in the farmland and the plastic bag remain in the field for a long time, which will affect the permeability of the soil and hinder the flow of water, thus affecting the absorption of water and nutrients by the crops, inhibiting the growth and development of crops, resulting in Reduction of crops. If livestock eat plastic film, it will cause digestive diseases and even death of livestock. 3. Landfilling is still a major method of treating municipal waste in China. Due to the small density and large volume of plastic film, it can be very Quickly fill the site and reduce the ability of the landfill to dispose of garbage; Moreover, due to the soft foundation of the landfill, the harmful substances such as bacteria and viruses in the garbage can easily penetrate into the ground, pollute the groundwater and endanger the surrounding environment. Waste plastics are directly incinerated, causing serious secondary pollution to the environment. When plastics are incinerated, not only a large amount of black smoke is produced, but also The most toxic substance to date: Dioxin. Dioxins enter the soil for at least 15 months to gradually decompose, which can harm plants and crops; dioxin has serious damage to the liver and brain of animals. The pollution of dioxin from the incineration of garbage has become a very sensitive issue of concern worldwide.
At present, small convenience stores, breakfast shops, and food markets are still using and providing ultra-thin plastic bags. Obviously, the “plastic limit order” is a piece of paper. It is recommended that the urban and commercial departments strengthen the sales of supermarkets, shopping malls, bazaars and other retail outlets. , using the supervision and inspection of plastic shopping bags, gradually establish a product quality supervision mechanism for plastic shopping bags production enterprises, prevent unqualified plastic shopping bags from entering the market, continue to sell illegally, use ultra-thin plastic shopping bags, etc., in accordance with the "People’s Republic of China Product Quality Law and other laws and regulations will be investigated and dealt with.
