While we all notice the emissions exiting our vehicle's tailpipes, the emissions from brake dust and tire wear are often overlooked.

Scientists are now turning their attention to these lesser-known pollutants, which are emerging as significant environmental concerns. As studies begin to grasp the extent of such impacts from automotive use on our environment, we discuss how regulation of these materials and emissions may impact our existing regulatory scheme and the auto industry as a whole.

In this fourth episode of the Emerging Contaminants series, Jack Lyman speaks with Professor Greg Evans (University of Toronto) and Sean Dixon (Puget Soundkeeper) as they explore the role of contaminants like 6PPD and what future regulations might mean for the automotive sector.
