Toxic Nation | Pollution. It's In You.

A new study shows that many fragrances found in all kinds of products may release harmful chemicals.

Researcher Anne C. Steinemann, PhD, a professor of civil and environmental engineering and public affairs at the University of Washington, Seattle tested top-selling air fresheners and laundry supplies. She found about 100 different volatile organic compounds (VOCs) being released from these products. Some of the chemicals can be cancerous or cause harm to respiratory, reproductive, neurological and other organ systems.

The study suggests it may be difficult for people to avoid these chemicals, even in products that are labeled ‘scent free’. According to the researcher, even products called “unscented” sometimes contain a fragrance and a "masking" fragrance to make them odor-free.

The study is published in the Environmental Impact Assessment Review.
