Chemical Emissions from Residential Dryer Vents During Use of Fragranced Laundry Products
The researchers analyzed emissions from two residential dyer vents during the use of fragranced laundry products (detergents and dryer sheets).
What did the researchers discover?
More than 25 VOCs were emitted from the dryer vents.
Seven of these VOCs are classified as hazardous air pollutants (HAPs), and two as carcinogenic HAPs (acetaldehyde and benzene) with no safe exposure level, according to the U.S. Environmental Protection Agency.
Acetaldehyde emissions during use of one brand of laundry detergent would represent 3% of total acetaldehyde emissions from automobiles in the study area.
Virtually none of the VOCs identified in the analysis of the products were listed on the product label or the product MSDS.
Thus, consumers may not be aware of potentially hazardous chemicals emitted from dryer vents.
