How Glitter Could Be Damaging Rivers

即使是可生物降解的垃圾也可能造成伤害。

You might see it as part of someone’s Halloween makeup or tucked into a holiday greeting card. Sparkly glitter certainly makes an impact. But then it gets tossed or washed away. Eventually those tiny pieces of mirrored plastic make it into storm drains and then waterways.

根据新的研究,所有丢弃的闪光可能导致河流和湖泊的生态损坏。如果闪光是可生物降解的,它似乎真的似乎没有大大。它仍然造成伤害。

研究人员称,该研究是第一个看闪光在淡水栖息地的影响。它发现36天后,闪光的存在会影响水生植物浮萍(LEMA MINS)的根部长度。水中的叶绿素水平比没有闪光的水低三倍,表明微藻水平较低。

“微藻是初级生产者,如浮萍,它们位于食品网的底部,加强生态系统,对食品网站的任何影响,”Dannielle Green,Lead Author和Biology的高级讲师可能导致效果。“Anglia Ruskin University in the U.K., tells Treehugger.

“重要的是要注意,我们使用的浓度很高,因此代表了一个非常大的局部输入到水道中,例如在节日之后。我们需要进行更多的研究,看看较低的浓度,在更长的时间内,以确定安全水平。“

The results were published in theJournal of Hazardous Materials

禁止闪光

自古老的文明使用古老的文明使用上云母,玻璃和其他反射材料时,闪光已经存在于某种形式,以便向他们的绘画添加闪光。根据闪闪发光的拉洛斯,在20世纪30年代,新泽西州机械师亨利Ruschmann发明了一种方法来磨削像Mylar这样的塑料以制作散装量的闪光。

但最近,闪闪发光的比特一直在失去吸引力。

Trisia Farrelly, an environmental anthropologist at Massey University in New Zealand, has suggested thatglitter be banned

“There is a growing body of evidence to suggest that the toxins released by microplastics and the additional pollutants absorbed by plastics in aquatic environments — what some marine scientists are now referring to as ‘poison pills’ — can bioaccumulate up the food chain with the potential to disrupt the endocrine systems of sea life, and us when we consume seafood,” she said in a大学释放

In the U.K., several major retailers have announced that they won’t use glitter in any in-house products this holiday season,纽约时报报告。杂货链莫里森和Waitrose百货商店John Lewis今年没有闪光牌,包装纸或其他假日物品。

“Glitter is made from tiny particles of plastic and is an ecological hazard if it becomes dispersed on land, rivers and oceans — where it takes hundreds of years to degrade, said Morrisons in astatement

闪光经常与微珠相比,塑料微小的塑料,一旦添加到个人护理产品中,用于皮肤去角质。微生物以来已经有了在美国的冲洗化妆品中禁止禁止。, 以及加拿大和U.K.以及世界各地的其他几个国家。

绿色说,微珠和闪光对淡水生态系统具有相当的影响。

“观察到的效果非常相似,”她说。“其他研究发现,其他类型的微塑料可导致鸭草的影响可能会导致类似的影响。”
