Disposable lunch boxes are mainly composed of polystyrene, ethylene and other polymer compounds, which are difficult to decompose, toxic, buried in the soil for a hundred years will not be degraded and other characteristics. As it is difficult to degrade? Therefore, it will also cause new pollution to the environment. It is white pollution, in the combustion will release a large number of toxic gases, and two hundred years do not decay, causing serious harm to the environment. At the same time, due to some foaming tableware raw materials in the concentration of harmful substances exceeds the standard, processing technology control is not good, the use of the process temperature is too high, will lead to tableware "with poison". Foreign research results show that polystyrene polymer in the synthesis process, if not completely polymerized, will be synthesized styrene monomer, dimer, trimer dissolved, with which to pack food, the health hazards are also great. Especially when it is loaded with hotter food, the harmful substances inside it will be sucked out and condense on the food, and when people eat such food, not only the liver and kidneys will be damaged, but also the function will be mutated. Foamed plastic has been scientifically proven to be one of the most serious killers of health.
Now disposable lunch boxes can be found everywhere, if a student in school every day to use two lunch boxes, if a school has 1,000 students, that day will have to produce 2,000 lunch boxes, think of the whole country, how many lunch boxes will be produced a year, the figures are alarming, at present, Shanghai's daily production of garbage for an average of 11,000 tons per day, of which the waste of plastics accounted for about 7% of the total amount of waste plastics, including disposable plastics, discharged into the environment every year. The total amount of waste plastics discharged into the environment each year, including disposable fast-food containers, plastic bags, beverage bottles and plastic film, amounted to 290,000 tons. The most eye-catching is the disposable lunch box, the daily production of 1.84 million, the annual 670 million, weighing more than 3,300 tons. People can often be seen on the river, green belts, railroads and small and medium-sized roads, a white Styrofoam lunch boxes were thrown, "white pollution" name came from.
These disposable styrofoam tableware in the high temperature above 65 degrees Celsius will produce harmful toxins and carcinogens dioxin, "dioxin" is a toxic chlorine-containing compounds, it is the world's most toxic known toxic compounds, carcinogenicity is extremely strong, able to cause serious skin diseases and injuries to the fetus Dioxin" is a toxic chlorine-containing compound that is highly toxic and carcinogenic, causing serious skin diseases and injuring the fetus, as well as the possible feminization of males; the direct and indirect treatment cost of one ton of disposable styrofoam plastic garbage is more than 10 times its original production value. Therefore, these "white pollutants" not only add unwarranted economic pressure on the country and the people, but also leave a lot of problems for future generations. Moreover, in the production of foam lunch boxes, Freon is used as the blowing agent, and the main raw material is polystyrene. As we all know, Freon is an ozone-depleting substance, which makes the atmosphere produce ozone holes. And polystyrene is a carcinogenic substance, it will cause reproductive dysfunction.
They pose a threat to the survival of animals. Foam products discarded on land or in water bodies are swallowed by animals as food, leading to their deaths. Last year, 20 families of herders*** on the shores of Qinghai Lake had nearly 1,000 sheep killed as a result, with an economic loss of about 300,000 yuan. Sheep like to eat the trash heap wrapped in oily residue, but often even the foam together, due to eat the foam for a long time to stay in the stomach is difficult to digest, these sheep's stomach is crowded, can no longer eat, and finally can only be alive and starve to death. Such things are common in zoos, pastoral areas, rural areas and oceans.
Such a vicious foam lunch box, not only in the production and use of the harm brought to us, in the treatment will also bring more new problems. At present, the treatment of foam lunch boxes are generally used to incinerate, buried, thrown away. If buried, the foam lunch box in the environment for about 200 years to decompose, but also impede the growth of plant roots, may also contaminate groundwater. Throwing them away provides a breeding ground for mosquitoes, flies and bacteria to survive and multiply. There is also an effective way to deal with the use of biodegradable lunch boxes, but their into decomposition is not complete, there are still some flaws.
To keep the hazards of the lunch box away from us, we must start from everyone, we have to avoid the use of disposable lunch boxes in school, it is best to bring their own lunch box to play meals, everyone is less of a daily will reduce a lot of garbage, and I hope to be able to study as soon as possible a lower-cost environmentally friendly lunch boxes, the national government to increase the efforts to rectify the input of some funds to reduce the cost of some of the environmentally friendly lunch box to get popularized. The government should increase its efforts to improve the situation and invest some funds to reduce the cost and popularize the eco-friendly lunch box.
Protecting our environment is also concerned about our health, so that we can live in a comfortable environment. Whether it is the past, present or future, whether it is the family, the country or the world, the environment is always our friend, treating our friends well is treating ourselves well. Protect me our environment also to meet the arrival of the Olympic Games.
