I am not surprised:
The same University of Washington researcher who used chemical sleuthing to deduce what’s in fragranced consumer products now has turned her attention to the scented air wafting from household laundry vents. The findings, published online this week in the journal Air Quality, Atmosphere and Health, show that air vented from machines using the top-selling scented liquid laundry detergent and scented dryer sheet contains hazardous chemicals, including two that are classified as carcinogens.
“This is an interesting source of pollution because emissions from dryer vents are essentially unregulated and unmonitored,” said lead author Anne Steinemann, a UW professor of civil and environmental engineering and of public affairs. “If they’re coming out of a smokestack or tail pipe, they’re regulated, but if they’re coming out of a dryer vent, they’re not.”
Analysis of the captured gases found more than 25 volatile organic compounds, including seven hazardous air pollutants, coming out of the vents. Of those, two chemicals – acetaldehyde and benzene – are classified by the Environmental Protection Agency as carcinogens, for which the agency has established no safe exposure level.
“These products can affect not only personal health, but also public and environmental health. The chemicals can go into the air, down the drain and into water bodies,” Steinemann said.
