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)境中變成污染物

2、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 sides"visual pollution" caused by pollution,it also potentially harmful.Plastic structuralstability,noteasy to benatural mic

11、的。如果用這類塑料袋盛裝含油類食品及高溫食物，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

12、 harmful ingredients will be dissolved into food, harm to people's 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.
