一次性塑料袋的危害

1、使用一次性塑料袋的危害Againstthe use of disposable plastic bags塑料袋的确给我们生活带来了方便，但是这一时的方便却带来长久的危害。Plastic bags do give us life to bring the convenience, but it a convenient but lasting harm.塑料袋回收价值较低，在使用过程中除了散落在城市 街道、旅游区、水体中、公路和铁路两侧造成视觉污染”污染外，它还存在着潜在的危害。塑料结构稳定，不易被天然微生物菌降解，在自然环境中长期不分离。这就意味着废 塑料垃圾如不加以回收，将在环境中变成污染物

5、状况开展了一次调查，结果发现， 送检样品蒸发残渣均不符合健康标准。据健康专家介绍，蒸 发残渣指标能反映出塑料食品袋和一次性餐盒在使用过程 中遇醋、酒、油等液体时析出残渣、重金属的多少，而残渣 和重金属的存在会对人体健康产生不良影响，特别是对处于 成长期的儿童和青少年的健康影响会更大。再有，残渣还会 对食品的色、香、味造成直接影响。另外，一次性塑料袋还 会释放有毒气体污染食品，长期食用一次性塑料袋包装的食 物易引发中毒。据了解，目前市面上用来包装食品的塑料袋 的制造材料，一般都是聚乙烯和聚丙烯，而一次性塑料袋大 多是聚氯乙烯和聚苯乙烯制成的再生塑料制品，对人体是有 害的。其中有相当数量是利用垃圾

6、站收购的废旧塑料再生材料，且未经消毒，很可能含有大量病菌On the one hand ,the impact on the human body:forbreakfast,cooked food,vegetables,fruits,snacksEvery day,when weputall kinds of foodin plasticfood bagsordisposable lunch box,you may not realize,healthdanger isquietly come.Not long ago,the relevant departments of thecityhe

11、的。如果用这类塑料袋盛装含油类食品及高温食物，塑料中 的有害成分就会溶解到食品中，危害人们的身体健康。Some manufacturers have also added some toxic stabilizers in the process of disposable plastic bags, the plastic bag is absolutely can not be used for food packaging. If food and hot food containing oil filled with this kind of plastic bags, plastic

12、 harmful ingredients will be dissolved into food, harm to people's health.另一方面，对环境的影响： 1两百年才能腐烂。塑料 袋埋在地下要经过大约两百年的时间才能腐烂，会严重污染 土壤；如果采取焚烧处理方式，则会产生有害烟尘和有毒气体，长期污染环境。On the other hand,the impact on the environment:1, two hundred years to decay. Plastic bags buried would take about two hundred years t
