一次性塑料餐具用聚苯乙烯、聚丙烯、聚氯乙烯等高分子化合物制成的塑料制品,具有毒性較低、熔點較高、可塑性強、生產簡便等特點,成為制造便宜、隨用隨棄的一次性餐盒的材料。然而,一次性塑料餐具在帶給我們方便的同時,還會產生多種副作用構成對人體的直接污染和對環境的二次污染。

Plastic products made of polystyrene, polypropylene, polyvinyl chloride and other macromolecule compounds for disposable plastic tableware are characterized by low toxicity, high melting point, strong plasticity and simple production. They have become excellent materials for making disposable lunch boxes with low cost and discarded at random. However, disposable plastic tableware can not only bring us convenience, but also produce a variety of side effects, which constitute direct pollution to human body and secondary pollution to the environment.
一次性發泡餐具在生產過程中要消耗大量屬臭氧層消耗物質的發泡劑,從而危及地球的保護傘———臭氧層;由于我國政府已開始限制一次性發泡餐具的生產,所以市面上多有非法廠家所生產的餐盒。如此一來,產品質量尤其是衛生也成了問題;有毒有害物質(如發泡劑),在較高溫度下會溶出并被食物吸收,從而對人體造成微量污染,長久沉積損害健康。如果有害物質超標,其危害更大;聚苯乙烯制造的餐盒降解周期極長,在普通環境下可達200年左右。也就是說,在很漫長的一段歲月里,它將“我行我素”,保持自己的高分子形態不變。因此它不僅破壞了環境,而且給人類的生存帶來了較大的危害。
Disposable foamed tableware in the production process to consume a large number of ozone layer depleting substances foaming agent, thus endangering the earth's umbrella - ozone layer; because our government has begun to restrict the production of disposable foamed tableware, so there are many illegal manufacturers on the market. As a result, product quality, especially hygiene, has become a problem. Toxic and harmful substances (such as foaming agents) dissolve at higher temperatures and are absorbed by food, thus causing micro-pollution to the human body and long-term deposition damage to health. If the harmful substances exceed the standard, the harm will be more serious. The degradation period of Polystyrene-Made lunch boxes is very long, which can reach about 200 years in ordinary environment. That is to say, in a long period of time, it will "go its own way" and keep its polymer morphology unchanged. Therefore, it not only destroys the environment, but also brings great harm to human survival.
一次性木筷我國森林覆蓋率僅為16.55%,卻是出口一次性木筷的大國。我國北方的一次性筷子產業每年要向日本和韓國出口木筷150億雙,耗材130萬立方米,相當于減少森林蓄積量200萬立方米。筷子在加工過程中均采用二氧化硫熏蒸的方式漂白,熏蒸的時間越長,筷子越白,聞起來也越酸。制造者在以二氧化硫熏蒸的方式漂白后,通常忽略水煮步驟。
The forest coverage of disposable wooden chopsticks in China is only 16.55%, but it is a big country exporting disposable wooden chopsticks. The disposable chopstick industry in northern China exports 15 billion pairs of wooden chopsticks to Japan and Korea every year, consuming 1.3 million cubic meters, which is equivalent to reducing the forest stock by 2 million cubic meters. Chopsticks are bleached by sulfur dioxide fumigation in the process of processing. The longer the fumigation time, the whiter the chopsticks are, the more acid they smell. After bleaching by sulfur dioxide fumigation, the manufacturer usually neglects the boiling process.

殘留的二氧化硫和其它物質結合便會成為亞硫酸鹽,而亞硫酸鹽在醫學界被認為可能導致哮喘。同時一次性筷子運輸、批發工序繁雜,整個過程多次由不同人經手,而且在運輸儲藏中為了防潮、防蟲等,撒上不同的藥品。一次性筷子不僅感官和理化指標達不到,即使基本的細菌含量等衛生指標也很難達到,存在很大的衛生隱患,是導致各種疾病的發生和傳播的媒介。
Residual sulfur dioxide, combined with other substances, becomes sulfite, which is thought to be a potential cause of asthma in the medical community. At the same time, the transportation and wholesale processes of disposable chopsticks are complicated, and the whole process is handled by different people many times. In order to prevent moisture and insects, different medicines are sprayed in transportation and storage. Disposable chopsticks can not reach not only sensory and physical and chemical indicators, but also the most basic hygienic indicators such as bacterial content. They have great potential health hazards and are the media leading to the occurrence and spread of various diseases.
3000雙一次性筷子等于一棵20年的大樹。我國每年消耗一次性筷子450億雙,耗費木材166萬立方米,需要砍伐大約2500萬棵大樹,減少森林面積200萬。
3000 pairs of disposable chopsticks are equivalent to a 20-year-old tree. China consumes 45 billion pairs of disposable chopsticks and 1.66 million cubic meters of timber every year. It needs to cut down about 25 million trees and reduce the forest area by 2 million square meters.
