3個已知事實,需要知道重複使用寶特瓶的危害

從小我們就很容易用寶特瓶重複裝水,就算到現在也會,因為真的很方便,帶著不重、髒了也不心疼還可以直接丟掉。更會覺得很環保,更加地重複利用。
但現在的問題是,重複使用的寶特瓶會危害我們的健康,三個已知的事實,你應該要知道並注意你使用寶特瓶的習慣,更重要的的是,有小朋的的,要跟重複使用的小朋友說(很多小孩這樣的行為很嚴重)。

細菌可以在水瓶茁壯成長

如果你常重複使用寶特瓶,要特別注意,研究顯示,重複使用寶特瓶,容易產生刮痕或裂痕,在這些裂痕中,容易孕育細菌,就跟切菜的砧板沒有什麼不同,必須徹底的清洗乾淨,已確保所有藏匿在裂痕中的細菌都洗乾淨了。

徹底清洗你的寶特瓶可以減少細菌的風險,特別是你利用溫的肥皂水,不過,清洗可能造成保特瓶的損壞,畢竟它的設計上並沒有針對重複使用來加強。

你的寶特瓶裡面的細菌是透過嘴巴進到身體裡面,所以,如果沒有把細菌洗出來,這個寶特瓶就跟實驗室的培養皿一樣,一個在University of Calgary 的研究發現,一組小學生的水瓶(已被重複使用多次)就算認真清洗,細菌的數量遠高於飲用水的合格標準,不得不承認,這些瓶子在室溫下一天,就讓這個寶特瓶成了細菌的完美生長環境。

一些專門重複使用的水瓶,也不完全一定安全,因為他們也可能產生刮痕,容易藏匿細菌,不過廣口瓶比較容易清洗乾淨,唯一的方法就是清洗乾淨呀!

對細菌最好的防範措施,使用一次性的寶特瓶,但不重複使用,因為窄嘴的設計,使它們非常難的清洗。如果使用可重複的瓶子,挑選廣口瓶,讓你可以輕易清洗其內部,以確保內部乾淨。最後,一定要洗手,因為這些細菌會透過你接觸瓶子的時候,附著在瓶子上面。

清洗水瓶可能導致化學品洩漏

前面有提到,要用溫水清洗瓶子是有原因的,因為當溫水和肥皂可以抑制細菌生長,不過用來清洗寶特瓶或一次性的奶瓶是非常不建議的,因為它們的塑料沒有設計以這種方式進行加熱,會存在著危險化學品滲透出來的風險。

曾經有一起事件發生在杜拜,一個十二歲的女童,因為連續十六個月習慣使用一個SAFA牌礦泉水瓶,她得了癌病。
寶特瓶裡面,一種叫做 polyethylene terephthalate 或簡稱 PET的塑膠,裡面含有一些叫做diethylhydroxylamine 或簡稱DEHA的潛在致癌物質,長期使用會有致癌風險

針對化學品洩漏的問題,最好的防範方法是使用玻璃或著不鏽鋼瓶,這樣你只需要確認你洗乾淨並擦乾他們,避免落入上述的細菌問題即可。

大多數水瓶的細菌存在在我們的嘴巴裡

寶特瓶提供了細菌完美的生態系統,你也知道要注意把寶特瓶清洗乾淨,但是,構成寶特瓶成為細菌生長的最大風險是我們的嘴巴。

不僅是我們的嘴巴含有細菌,然後在喝水的時候轉移到水瓶上,也意味著瓶嘴螺旋紋的地方是完美的養殖微生物的地帶。有一項研究表示,他們讓一組勇敢的受試者重複使用相同的水瓶一個星期,並且奉命不可以洗乾淨,在一週結束後檢測水瓶的細菌含量,發現瓶口的部分,有大量會導致人體食物中毒的細菌,一直重複使用可能會導致某種疾病。

如果你使用的是一次性的寶特瓶,請就只使用一次吧!
如果你擔心瓶口處淪落為細菌養殖場,你可以不接觸嘴巴的喝水(隔空倒水)。
如果你使用重複的水瓶,請務必清洗乾淨,因為這是唯一辦法。
寶特瓶釋放化學毒物的概念已經滿廣泛了,但衛生習慣還是需要多加注意,
並且一定要注意小朋友,使用寶特瓶的概念。
