一次性塑料袋的危害

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永久存在并不断累积，会对环境造成极大危害。lower the value of recycling plastic bags,in addition totheuseofscatteredinthecitystreets,tourist areas,water,railwayandhighwayonbothsidesvisual pollutioncausedbypollution,italsopotentially harmful.plasticstructuralstability,noteasytobenatural microbialdegradation,thenaturalenvironmentisnota longseparation.this means that the wasteplastic garbage ifnotrecovered,willbecomeapermanentpresenceofcontaminantsintheenvironmentandcontinueto accumulate,will causegreat harm to the environment.精品资料使用一次性塑料袋或发泡塑料饭盒不仅严重影响人们的身体健康，还对环境造成严重的污染。具体表现为theuseofdisposableplasticbagsorplasticfoamlunch boxes not only seriously affects peoples health, butalsocauseseriouspollutiontotheenvironment.specificperformance一方面，对人体的影响：对于早点、熟食、蔬菜、水果、小吃每天，当我们把各类食品装入塑料食品袋或一次性餐盒时，也许你还没有意识到，健康的危险正在悄然降临。前 不久，有关部门对某市的早点摊和熟食品小店使用的塑料食 品袋和一次性餐盒的卫生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,snacks.every day,when we putall kinds of foodin plasticfood bagsordisposable lunch box,you may not realize,healthdanger isquietly come.not long ago,the relevant departments of thecityhealthbreakfast spreadand cooked foodshopuse plasticfoodbags and disposabletablewarecarried out asurvey,results showed that,the samplesdo notmeet the health standards ofevaporation residue.according to health experts,evaporation residueindex canreflect theplastic foodbags and disposablelunch boxin use processinvinegar,wine,oil and otherliquidprecipitationof heavy metals,how muchresidue,andresidueand heavy metalspresence willhave a negative impact on human health,especially the healtheffects onalong-terminchildren and adolescentswill be greater.again,a direct impactonthe residuewillfood color,fragrance,taste.in addition,disposable plastic bagswill release toxic gasespollutionfood,long-term consumption ofdisposableplastic bagsof foodis easytocause poisoning.it is understood,materialscurrentlyused in food packagingplastic bags,are generallyof polyethylene and polypropylene,anddisposable plastic bagsarerecycledplasticsmade frompolyvinyl chloride and polystyrene,is harmful to human body.there are quite a number ofthe garbagestation acquisitionofwaste plastic recycling material,and withoutdisinfection,itmay contain a large number ofbacteria.有的生产厂家在加工一次性塑料袋的过程中还会加入一些有毒的稳定剂，这类塑料袋是绝对不能用于包装食品 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 harmful ingredients will be dissolved into food, harm to peoples 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 to rot in the ground, will beseriouslypollutedsoil;ifyoutaketheincineration,willproduceharmfulfumesandtoxicgases,long-term pollution of the environment.2、降解塑料难降解。市场上常见的 “降解塑料袋 ”，实际上只是在塑料原料中添加了淀粉，填埋后因为淀粉的发酵、细菌的分解，大块塑料袋会分解成细小甚至肉眼看不见的碎片。这是一种物理降解，并没有从根本上改变塑料产品的化学性质。2,thedegradationofplasticrefractory.thecommon market degradable plastic bags, is actually in the plasticrawmaterialsaddedstarch,landfillafterfermentation,bacteria because the decomposition of starch, large plastic bags into small pieces or even invisible to the naked eye.thisisakindofphysicaldegradation,andnochemical change fundamentally plastic products.3、影响土壤的正常呼吸。塑料袋本身不是土壤和水体的基本物质之一， 强行进入到土壤之后，由于它自身的不透气性， 会影响到土壤内部热的传递和微生物的生长，从而改变土壤的特质。这些塑料袋经过长时间的累积，还会影响到农作物吸收养分和水分，导致农作物减产。3, affecting the normal respiration of soil. one of the basic material of plastic bags is not soil and water, forced entry into the soil, due to non permeability of its own, will affecttheinternalheattransferofsoilandthegrowthofmicroorganisms, thereby changing the soil characteristics.thesebagsareaccumulatedoveralongtime,butalso affect crops absorb nutrients and moisture, leading to crop production.4、易造成动物误食
