不环保的一次性餐具能造成多大的危害？

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.

一次性发泡餐具在生产过程中要消耗大量属臭氧层消耗物质的发泡剂，从而危及地球的保护伞———臭氧层；由于我国政府已开始限制一次性发泡餐具的生产，所以市面上多有非法厂家所生产的餐盒。如此一来，产品质量尤其是卫生也成了问题；有毒有害物质（如发泡剂），在较高温度下会溶出并被食物吸收，从而对人体造成微量污染，长久沉积损害健康。如果有害物质超标，其危害更大；聚苯乙烯制造的餐盒降解周期极长，在普通环境下可达200年左右。也就是说，在很漫长的一段岁月里，它将“我行我素”，保持自己的高分子形态不变。因此它不仅破坏了环境，而且给人类的生存带来了较大的危害。

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.

一次性木筷我国森林覆盖率仅为16．55％，却是出口一次性木筷的大国。我国北方的一次性筷子产业每年要向日本和韩国出口木筷150亿双，耗材130万立方米，相当于减少森林蓄积量200万立方米。筷子在加工过程中均采用二氧化硫熏蒸的方式漂白，熏蒸的时间越长，筷子越白，闻起来也越酸。制造者在以二氧化硫熏蒸的方式漂白后，通常忽略水煮步骤。

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.

残留的二氧化硫和其它物质结合便会成为亚硫酸盐，而亚硫酸盐在医学界被认为可能导致哮喘。同时一次性筷子运输、批发工序繁杂，整个过程多次由不同人经手，而且在运输储藏中为了防潮、防虫等，撒上不同的药品。一次性筷子不仅感官和理化指标达不到，即使基本的细菌含量等卫生指标也很难达到，存在很大的卫生隐患，是导致各种疾病的发生和传播的媒介。

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双一次性筷子等于一棵20年的大树。我国每年消耗一次性筷子450亿双，耗费木材166万立方米，需要砍伐大约2500万棵大树，减少森林面积200万平方米。

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.
