Genu's boss, if you're listening, give this dude some more time to take runs. But anyway, this was his eureka moment. During his post-run shower, the location of so many great ideas, he realized how to find the additives.

They knew their mysterious murderous chemical, the product after a transformation, was made of very specific amounts of carbon, nitrogen, hydrogen, and oxygen. So he searches for a tire additive with the same carbon and nitrogen makeup as their murderous chemical. And they found it, a tire additive called 6-PPD that helps tires last longer because it's an antioxidant.

It reacts with ozone to make 6-PPD-Quino. That has more oxygen bonds and it kills the coho. This breakthrough got a lot of attention because, well, everyone knew, yeah, probably not great that all these tire particles are full of all these chemicals.

Changing the way people like Nick Malden think. He's with a company called Emissions Analytics in the UK. They used to study tailpipe emissions. These days, they do a lot of work on tire emissions. All the particles that go into the air and waterways as your tires wear away.

Now, to be clear, some researchers into air and water quality have always been worried about tire emissions. But the general public, regulators, the auto industry were much more focused on tailpipes. And regulations to cut tailpipe emissions have, in fact, been super effective. They've come down a lot.

So much that Nick's company, as well as peer-reviewed research, have found that tire emissions are now on some metrics a bigger problem than tailpipe emissions.

Five versus a hundred. And to add a wrinkle, this realization is coming right as electric vehicles are becoming more popular. And they're heavier. Heavier vehicles mean more tire emissions as you drive. One researcher told me, just picture using a rubber eraser. The harder you press, the more you wear it down.
