I wonder what the air quality is like in and around racing car circuits, given brake, tire, and exhaust pipe emissions.

- spike021 3y agoI'd also be curious about brake pad composites. In car brakes you can have slightly different designs/materials for pads which cause the balance of noise<->dust<->temperature performance to differ. For instance if you want to reduce dust emission, generally you get brakes that are much louder in my experience until they warm up but they are much "cleaner".
- adonovan 3y agoIt was especially terrible before 2006, which is when NASCAR's exemption to the lead ban finally expired, creating a perfect natural experiment to answer the question: how much did the health of people downwind of NASCAR arenas improve after the ban, and conversely, what was the dollar cost of the health externality of lead. Spoiler alert: more than $1000 / gram (approx. 1 tank of fuel). https://www.aeaweb.org/articles?id=10.1257/pol.20190654 https://www.aeaweb.org/articles?id=10.1257/pol.20190654
