I do feel like we dont really have sense of effects of particulate matter on the body. How does the risk of this compare to walking down a street with lots or running ICE cars? Or when you go into a basement and can smell the natural gas burning - is that a similar risk?
If you told me being in the same room as a PLA printer was 10x worse I would believe it. If you told me being next to a car for 5 seconds was 10x worse I'd believe it. As far as I've read we dont have great metrics.
- nick__m 4y agoIn "ICE cars" the biggest sources of particulate matter are the tires and brakes¹, don't electric car have those too ? 1) https://www.researchgate.net/publication/317425487/figure/fig3/AS:613874445344789@1523370481529/Particulate-matter-formation-PMF-of-different-vehicle-technologies-based-on-10.png https://www.researchgate.net/publication/317425487/figure/fi...
- fasthands9 4y agoGood point! I was mistaken. Though I think larger point stands that its very hard to know risks of different particulate sources (like brakes).
- evan_ 4y agoTires yes, but since EVs use regenerative braking at least some of the time I would think they'd be slightly better in that regard. Regenerative braking does not engage the brake pads.
- 3pac 4y agoWe really do not have a sense of these things. We are often overconfident in our limited senses. I was being poisoned by carbon monoxide from my oven and did not realize it until it was too late. I told myself "it cannot happen to me". Thank God for a few related HN comments, and a hunch to buy a CO meter.
