一次性塑料袋的危害

1、使用一次性塑料袋的危害Againstthe use of dis posable pl astic bags塑料袋的確給我們生活帶來了方便，但是這一時(shí)的方/來便卻帶久的危害。PI astic bags do give us life to bring theconvenience, but it a convenient but lasting harm.塑料袋回收價(jià)值較低，在使用過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 pl astic bags,in additionto the use of scatteredin the city streets,touristareas,water,railway and highwayonboth sides"visualp ollution"caused by p ollution,italsopo tentiallyharmful.

11、a.有的生產(chǎn)廠家在加工一次性塑料袋的過程中還會(huì)加入二中些有毒的穩(wěn)定劑，這類塑料袋是絕對(duì)不能用于包裝食品的。如果用這類塑料袋盛裝含油類食品及高溫食物，塑料的有害成分就會(huì)溶解到食品中，危害人們的身體健康。Some manufacturers have also added some toxicstabilizers in the p rocess of dis po sable pl astic bags, the pl astic bag is absolutely can not be used for food p ackaging. If food and hot food contain

12、ing oil filled with this kind of p lastic bags, pl astic harmful ingredients will be dissolved into food, harm to peopi e'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 imp act on the environment: 1, two hundred years to decay.

13、 PI astic bags buried would take about two hundred years to rot in the ground, will be seriously polluted soil; if you take the incineration, will p roduce harmful fumes and toxic gases, long-term p ollution of the environment.2、降解塑料難降解。 市場(chǎng)上常見的 降解塑料袋”，實(shí)際上只 是在塑料原料中添加了淀粉，填埋后因?yàn)榈矸鄣陌l(fā)酵、細(xì)菌的分解，大塊塑料袋會(huì)分解成細(xì)小甚至

14、肉眼看不見的碎片。這是一種物理降解，并沒有從根本上改變塑料產(chǎn)品的化學(xué)性質(zhì)。2, thedegradation of plastic refractory.Thecommonmarket"degradable pl astic bags", isactuallyin theplasticraw materials added starch,landfillafterfermentation, bacteria because the decompositionofstarch, large plasticbags into small pieces or even invis

This is a kind of physical degradation, and no chemical change fundamentally pl astic p roducts.3、影響土壤的正常呼吸。塑料袋本身不是土壤和水體的基本物質(zhì)之一，強(qiáng)行進(jìn)入到土壤之后，由于它自身的不透氣性，會(huì)影響到土壤內(nèi)部熱的傳遞和微生物的生長(zhǎng)，從而改變土壤的特質(zhì)。這些塑料袋經(jīng)過長(zhǎng)時(shí)間的累積，還會(huì)影響到農(nóng)作物吸收養(yǎng)分和水分，導(dǎo)致農(nóng)作物減產(chǎn)。3, affecting the normal resp iration of soil.
