文檔簡介
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了方便,但是這一時的方便卻帶來長久的危害。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,會對環(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

4、e use of disposable plastic bags or plastic foam lunch boxes not only seriously affects people's health, but also cause serious pollution to the environment. Specific performance一方面,對人體的影響:對于早點(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,也許你還沒有意識到,健康的危險正在悄然降臨。前 不久,有關(guān)部門對某市的早點(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
5、狀況開展了一次調(diào)查,結(jié)果發(fā)現(xiàn), 送檢樣品蒸發(fā)殘渣均不符合健康標(biāo)準(zhǔn)。據(jù)健康專家介紹,蒸 發(fā)殘渣指標(biāo)能反映出塑料食品袋和一次性餐盒在使用過程 中遇醋、酒、油等液體時析出殘渣、重金屬的多少,而殘渣 和重金屬的存在會對人體健康產(chǎn)生不良影響,特別是對處于 成長期的兒童和青少年的健康影響會更大。再有,殘渣還會 對食品的色、香、味造成直接影響。另外,一次性塑料袋還 會釋放有毒氣體污染食品,長期食用一次性塑料袋包裝的食 物易引發(fā)中毒。據(jù)了解,目前市面上用來包裝食品的塑料袋 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,對人體是有 害的。其中有相當(dāng)數(shù)量是利用垃圾
6、站收購的廢舊塑料再生材料,且未經(jīng)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)過大約兩百年的時間才能腐爛,會嚴(yán)重污染 土壤;如果采取焚燒處理方式,則會產(chǎn)生有害煙塵和有毒氣體,長期污染環(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 t

17、production.4、易造成動物誤食。廢棄在地面上和水面上的塑料袋,容 易被動物當(dāng)做食物吞入,塑料袋在動物腸胃里消化不了,易 導(dǎo)致動物肌體損傷和死亡。4, easy to cause the animal eating. Abandoned on the ground and on the surface of the plastic bags, easy to be animal as food ingestion, plastic bags in the animal stomach digest, easily lead to animal body injury and death
