全市民向保丽龙说 “不” !

  保丽龙的使用在国内相当普遍,甚至是到了泛滥程度。保丽龙是一种顽固的垃圾废弃物,乃众所周知的不争事实。此废料在自然界无法经由微生物作用分解,不会腐化,永久在大自然中,故不要说是一百年,甚至五百年后,今天使用过的保丽龙依久完好无损地存在地球上。

  同时,保丽龙的回收与再利用率很低,绝大部分的保丽龙混杂在垃圾当中,被丢至垃圾掩埋场或丢进焚化炉内焚烧。保丽龙在焚化时,会产生有害气体“戴奥辛”,造成环境公害。
  
  且制作保丽龙的过程中,使用的氟氯烷会破坏臭氧层,在土中无法腐烂,质量轻,很容易就随 风吹至河道,沟渠等,堵塞出水口,甚至造成水患,可谓环境杀手。由于保丽龙的耐热度只能维持在摄氏75-95之间,超过此温度会发生异臭变形的现象。若用保丽龙盛装热汤,因碗表面空隙内的空气受热造成。若盛刚炸过的食物,盘子表面会受热软化变形,甚至熔化。
  
  此外保丽龙不耐酸,柠檬与柳橙的酸性会腐蚀保丽龙。若用于微波炉内,会释放有毒物质,长期与人体接触会造成皮肤干燥,龟裂。且呼吸道吸入苯乙烯气体时
可能会压制中区神经造成心律不整,并损坏肾脏,肺脏的功能,引发头痛,疲倦及虚弱等现象
