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.
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.”
The research builds on earlier work that looked at what chemicals are released by laundry products, air fresheners, cleaners, lotions and other fragranced consumer products. Continue reading
