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 塑料袋的確給我們生活帶來(lái)了方便，但是這一時(shí)的方便卻帶來(lái)長(zhǎng)久的危害。 Plastic bags do give us life to bring the convenience, but it a convenient but lasting harm. 塑料袋回收價(jià)值較低，在使用過(guò)程中除了散落在城市街道、旅游區(qū)、水體中、公路和鐵路兩側(cè)造成“視覺(jué)污染”污染外，它還存在著潛在的危害。 塑料結(jié)構(gòu)穩(wěn)定，不易被天然微生物菌降解，在自然環(huán)境中長(zhǎng)期不分離。這就意味著廢塑料垃圾如不加以回收，將在環(huán)境中變成

2、污染物永久存在并不斷累積，會(huì)對(duì)環(huán)境造成極大危害。 Lower the value of recycling plastic bags,in addition to the use of scatteredin the city streets,tourist areas,water,railway and highwayon both sidesvisual pollution caused by pollution,it also potentially harmful.Plastic structuralstability,not easy to be natural microbial

3、degradation,the natural environment is not a longseparation.This means that the wasteplastic garbage if not recovered,will become apermanent presence ofcontaminants in theenvironmentand continue to accumulate,will causegreat harm to the environment.使用一次性塑料袋或發(fā)泡塑料飯盒不僅嚴(yán)重影響人們的身體健康，還對(duì)環(huán)境造成嚴(yán)重的污染。具體表現(xiàn)為 The

Specific performance一方面，對(duì)人體的影響：對(duì)于早點(diǎn)、熟食、蔬菜、水果、小吃每天，當(dāng)我們把各類食品裝入塑料食品袋或一次性餐盒時(shí)，也許你還沒(méi)有意識(shí)到，健康的危險(xiǎn)正在悄然降臨。前不久，有關(guān)部門(mén)對(duì)某市的早點(diǎn)攤和熟食品小店使用的塑料食品袋和一次性餐盒的衛(wèi)生狀況開(kāi)展了一次調(diào)查，結(jié)果

11、食物，塑料中的有害成分就會(huì)溶解到食品中，危害人們的身體健康。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 harmful ingredients

12、will be dissolved into food, harm to peoples health. 另一方面，對(duì)環(huán)境的影響：1、兩百年才能腐爛。塑料袋埋在地下要經(jīng)過(guò)大約兩百年的時(shí)間才能腐爛，會(huì)嚴(yán)重污染土壤；如果采取焚燒處理方式，則會(huì)產(chǎn)生有害煙塵和有毒氣體，長(zhǎng)期污染環(huán)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 to rot in the ground, will b
