一次性发泡塑料饭盒和塑料袋盛装食物严重影响我们的身体健康.当温度达到65℃时,一次性发泡塑料餐具中的有害物质将渗入到食物中,会对人的肝脏、肾脏及中枢神经系统等造成损害.我们现在用来装食物的超薄塑料袋一般是聚氯乙烯塑料.
早在四十年前,人们就发现聚氯乙烯塑料中残留有氯乙烯单体.当人们接触氯乙烯后,就会出现手腕、手指浮肿,皮肤硬化等症状,还可能出现脾肿大、肝损伤等症.在我国,我们用的超薄塑料袋几乎都来自废塑料的再利用,是由小企业或家庭作坊生产的.这些生产厂所用原料是废弃塑料桶、盆、一次性针筒等.生产时,首先用机械把原料粉碎成塑料粒子,再把塑料粒子放在一个水池里清洗.取出来晒干,再用机械把它压成膜,制成各种塑料袋.每次吃饭时,就有不少人用塑料袋装饭菜,他们不知道这种行为不仅危害环境,也危害自己的身体.
还会使土壤环境恶化,严重影响农作物的生长.我国目前使用的塑料制品的降解时间,通常至少需要200年.若被填埋,将直接占用土地,且1000年内难以降解,农田里的废农膜、塑料袋长期残留在田中,会影响农作物对水分、养分的吸收,抑制农作物的生长发育,造成农作物的减产.若牲畜吃了塑料膜,会引起牲畜的消化道疾病,甚至死亡.
填埋作业仍是我国处理城市垃圾的一个主要方法.由于塑料膜密度小、体积大,它能很快填满场地,降低填埋场地处理垃圾的能力；而且,填埋后的场地由于地基松软,垃圾中的细菌、病毒等有害物质很容易渗入地下,污染地下水,危及周围环境.
若把废塑料直接进行焚烧处理,将给环境造成严重的二次污染.塑料焚烧时,不但产生大量黑烟,而且会产生二恶英——迄今为止毒性最大的一类物质.二恶英进入土壤中,至少需15个月才能逐渐分解,它会危害植物及农作物；二恶英对动物的肝脏及脑有严重的损害作用.焚烧垃圾排放出的二恶英对环境的污染,已经成为全世界关注的一个极敏感的问题.
我国“白色污染”现状
长江葛洲坝岸边漂浮堆积的“白色垃圾”,足容得下多人站立而不下沉.目前,长江上游顺江而下的大量“白色垃圾”不仅严重污染水面,也给葛洲坝水电站和在建的三峡水利枢纽未来的运行发电带来严重安全隐患.清理“白色垃圾”已迫在眉睫.
近年来,塑料制品的生产呈上升趋势.人们享受塑料制品给生活带来的好处的同时,也注意到：废旧塑料对生态环境的破坏日益加重.
塑料作为一种新型材料,具有质轻、强度高、防水、成本低等特点,被各行业所广泛采用.我国是世界上十大塑料制品生产和消费国之一.1995年我国塑料产量为519万吨,进口塑料量为600万吨；1996年我国塑料消费总量约1574万吨.据汉威机构预测：从现在起到本世纪末,中国将成为世界塑料消费增长最快的国家,年平均增长率为8.3％.
塑料制品广泛的使用的确给人们的物质需求带来了诸多便利.但是,使用后的塑料制品大量地被抛向人类赖以生存的自然环境,尤其是城镇、城郊和交通干线的两侧,已形成了触目惊心的“白色垃圾场”.仅据北京一个城市的调查：每年环境中的塑料袋约2.3亿个（约0.132万吨）、废农膜675万平方米（约0.3万吨）.全国废弃塑料物的总量是庞大,1995年便达200多万吨.治理“白色污染”已成为亟待解决的重要问题.
Disposable plastic foam food boxes and plastic bags containing a serious impact on our health. When the temperature reached 65 ℃ time, disposable plastic foam food containers will be in the infiltration of harmful substances to food, people have liver, kidney and central nervous system damage. We are used to hold food in general is the ultra-thin PVC plastic.
As early as four decades ago, people have found PVC in vinyl chloride monomer residue. When people after exposure to vinyl chloride, there will be the wrist, finger swelling, skin sclerosis symptoms, which may occur in splenomegaly, liver injury等症. In our country, we use almost all of the ultra-thin plastic bags from the recycling of waste plastics is a small business or home workshop production. These raw materials used in the production plant is obsolete plastic barrels, basins, such as disposable syringes. Production, first of all, the raw material by mechanical smashing into plastic particles, plastic particles and then placed in a pool cleaning. Check out the sun, and then mechanical pressure it film, made all kinds of plastic bags. Each meal, there are quite a few meals loaded with plastic bags, they did not know such acts are not only harmful to the environment, but also against their own body.
The soil environment will deteriorate, thus affecting the growth of crops. China's plastic products used in the degradation of time, usually at least 200 years. If the landfill, will have a direct occupation of land, and difficult to degrade during the year 1000, farm waste plastic sheeting, plastic bags left in the fields of long-term, will affect the crop for moisture, nutrient absorption, inhibiting the growth of crops, resulting in the production of crops . If animals eat the plastic film will cause the digestive tract of livestock diseases, or even death.
Landfill operation is still dealing with municipal solid waste in our country one of the main methods. As the plastic film density, size, it can quickly fill up space and reduce landfill site waste disposal capacity; Moreover, after the landfill site as a result of the soft ground, garbage bacteria, viruses and other harmful substances can easily infiltrate into the underground pollution of groundwater and endanger the surrounding environment.
If the direct burning of waste plastics processing, the environment will lead to serious secondary pollution. Plastic burning, not only emit a lot of smoke, and will produce dioxins - the largest to date for a class of toxic substances. Dioxins into the soil, at least 15 months in order to gradually break down, it will harm plants and crops; dioxin on the liver and brain of animals with severe damage to the role. Burning of refuse of dioxin emissions of the pollution of the environment has become the world's attention to an extremely sensitive issue.
China's "white pollution" the status quo
Gezhouba accumulation of the Yangtze River shore floating "white trash", accommodate more than enough to stand without sinking. At present, the upper reaches of the Yangtze River and the under-shun a large number of "white trash" is not only seriously polluted the water, but also to the Gezhouba Hydropower Station and construction of the Three Gorges Project to run the next generation of serious security risks. Clean-up "white trash" imminent.
In recent years, the production of plastic products increased. Plastic products for people to enjoy the benefits of living at the same time, also noted: waste plastics damage the ecological environment on the rise.
As a new type of plastic material, with lightweight, high strength, waterproof, low cost, have been widely used by various industries. China is the world's top ten production and consumption of plastics in the world. Plastics production in China in 1995 to 5.19 million tons, while imports of plastic six million tons; in 1996 China's total consumption of plastic about 15.74 million tons. It has been predicted Hanwei: From now until the end of this century, China will become the world's fastest growing plastics consumer countries, the average annual growth rate of 8.3 percent.
The use of a wide range of plastic products are indeed the people's material needs to bring a lot of convenience. However, the use of a large number of plastic products after being thrown the natural environment of human life, especially in towns, suburbs and traffic on both sides of Route, has formed a startling "white garbage dump." Beijing alone, according to a city survey: environment plastic bags each year about 230 million (about 01,320 tons), 6.75 million square meters of waste plastic (approximately 03,000 tons). The country's total amount of waste plastic materials is large, in 1995 reached more than 200 million tons. Treatment of "white pollution" has become an important issue to be settled urgently.
