一次性塑料袋的危害

1、使用一次性塑料袋的危害Againsttheuseofdisposableplasticbags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。Plasticbagsdogiveuslifetobringtheconvenience,butitaconvenientbutlastingharm.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)境中變成污染物永久存在并不斷累積，會(huì)對(duì)環(huán)境造成極大危害。Lo

5、渣還會(huì)對(duì)食品的色、香、味造成直接影響。另外，一次性塑料袋還會(huì)釋放有毒氣體污染食品，長(zhǎng)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(lái)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(duì)人體是有害的。其中有相當(dāng)數(shù)量是利用垃圾站收購(gòu)的廢舊塑料再生材料，且未經(jīng)消毒，很可能含有大量病菌。Ontheonehand,theimpactonthehumanbody:forbreakfast,cookedfood,vegetables,fruits,snacksEveryday,whenweputallkindsoffoodi

10、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，塑料中的有害成分就會(huì)溶解到食品中，危害人們的身體健康。Somemanufacturershavealsoaddedsometoxicstabilizersintheprocessofdisposableplasticbags,theplasticbagisabsolutelycannotbeusedforfoodpackaging.Iffoodandhotfoodcontainingoilfilledwiththiskindofplasticbags,plasticharmfulingredientswil

14、這些塑料袋經(jīng)過(guò)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, affectingthenormalrespirationofsoil.Oneofthebasicmaterialofplasticbagsisnotsoilandwater,forcedentryintothesoil,duetononpermeabilityofitsown,willaffecttheinternalheattransferofsoilandthegrowthofmicroorganisms,therebychangingthesoilcharacteristics.Thesebagsarea
