This is Scientific American's 60-Second Science, I am Adam Hinterthuer. Got a minute?

 

Laundry detergents1 and air fresheners have long promised to keep your house and clothes smelling sunshine fresh and rain shower clean. But what they haven't said is what exactly you're sniffing2 when you snuggle up in your just-washed sheets. After hearing from people who said strong scents3 made them sick, University of Washington researcher Anne Steinemann scratched the surface and found almost a hundred chemicals that weren't listed on the labels. According to her report in the journal Environmental Impact Assessment4 Review, plug-in air fresheners, scented5 sprays, dryer6 sheets and detergents all contained a mixture of volatile7 organic compounds.

Since manufacturers aren't required to list their ingredients for such consumer products, the boxes only admitted to containing a "mixture of perfume oils." But five out of the six products Steinemann tested emitted one or more so-called hazardous8 air pollutants9, which are carcinogens determined10 to have no safe exposure level by the EPA. While the study did not test for any human health risk from exposure to these chemicals, Steinemenn says the next time the air in the house smells stale, maybe you just open a window.

 

Thanks for the minute for Scientific American's 60-Second Science. I'm Adam Hinterthuer.
