新研究:亂丟的隱形眼鏡最終形成塑料微粒 可能造成水污染

瀏覽次數: 日期:2018年8月25日 09:59

“美瞳”能讓眼睛顯得又大又亮,是不少愛美女性的必備物品。不過,近日在美國化學學會年會暨展會上發布的一項新研究提醒人們,用完的“美瞳”等隱形眼鏡不要亂扔,以免造成對河流的塑料微粒污染。
 
  美國亞利桑那州立大學研究人員經調查發現,在美國,大約有4500萬人戴隱形眼鏡,其中15%至20%的人會把用完的隱形眼鏡丟進馬桶或水槽,估計每年進入美國下水道的隱形眼鏡總重量有6至10噸。
 
  隱形眼鏡通常由硅水凝膠等材料制成,屬于塑料。研究人員選取5種市面常見的隱形眼鏡材料,把它們暴露在污水處理廠使用的厭氧微生物和嗜氧微生物環境中,再用拉曼光譜儀檢測。他們發現,經污水處理廠使用的微生物長期處理后,隱形眼鏡發生物理降解,最終形成塑料微粒。
 
  這些塑料微粒會隨著處理過的污水排入自然環境中,對水生生物造成威脅。
 
  參與研究的亞利桑那州立大學的查理·羅爾斯凱說,水生生物會把塑料微粒誤當成食物,然而塑料不能被消化,所以這勢必影響其消化系統。一些水生生物最終會進入人類的食物供應鏈,這意味著人類有可能接觸到這些塑料微粒及微粒表面附著的污染物。
 
  研究人員呼吁,隱形眼鏡廠家應在包裝上加入提示,提醒人們不要把廢棄的隱形眼鏡扔進下水道,而是應與其他固體垃圾一道處理。
