Dandruff Shampoo Could Mess Up
Waterways
Toxicity
testing毒物測試 on shampoo that fights flakes頭皮屑 reveals that it's bad for plants and animals once it's in wastewater廢水.
David Biello reports
Every time
you wash your hair, a lot of shampoo goes down the drain隨著水管排出去. And if
you're bothered by tiny
white
flakes頭皮屑,
odds are很有可能
you use a shampoo that deals with dandruff.
Such medicinal shampoos含藥性洗髮精 often include a fungicide殺菌劑.
A fair amount of fungicide thus ends up at the local wastewater treatment plant廢水處理廠.
Those industrial facilities remove a lot of
stinky髒臭 stuff. But they mostly fail to
grab the drugs
in soaps, shampoos, toothpastes, perfumes, sunscreen and other skincare
products that our daily habits add to wastewater.
Now a study
has detected
fungicides from anti-dandruff shampoos in the water. And even at concentrations
as low
as 0.5 micrograms毫克 per liter一公升 of
H2O such fungicides can hurt many organisms生物, from tiny algae to big plants
and fish. The study is in the journal Environmental Toxicology and
Chemistry.
Exposure to
the fungicide is chronic慢性的: It gets
repeated day after day after day. The algae just die. But bigger plants
suffer retarded growth成長緩慢. And animals like fish are affected, too, since they
share similar cellular
mechanisms細胞機制 with their distant relatives遠親. We might want to start coming up with想出
ways to get our dandruff shampoo—and other personal care products個人衛生用品—out of the drink.
