Well I read the article and got excited about eliminating internal combustion engines...

"Electric vehicles are estimated to emit 5-19% less PM10 from non-exhaust sources per kilometre than internal combustion engine vehicles (ICEVs) across vehicle classes. However, EVs do not necessarily emit less PM2.5 than ICEVs. Although lightweight EVs emit an estimated 11-13% less PM2.5 than ICEV equivalents, heavier weight EVs emit an estimated 3-8% more PM2.5 than ICEVs" So. It depends. It's sometimes slightly be…
True, but these are all less than 20%, a change which is likely indistinguishable for any sort of risk factors, and likely well within the measurement error for something difficult to measure like this. The true change we need to make is drastically reduce car use, to a tiny fraction of its current use. This is a hard social problem, however, particularly for the older generations who tend to wield power in most gove…
Government leaders in the states can't imagine this reality or, if so, can't imagine it changing sufficiently in their lifetimes to invest the political capital in. The US will never change.

Exactly right, tire and brake dust are still awful with EVs, though contra the slight implication in the headline, it's no worse than the current situation with ICE vehicles. And the brake dust aspect may slightly reduce due to regenerative braking.
I know essentially nothing about this topic, but it seems likely that some particles are more dangerous than others (though I've seen no suggestion of that). I'd prefer to go after the elephants in the room before the hamsters. There are MULTITUDES of particles in circulation everywhere everyday. If the impact of only some these are especially dire, we should be able to triage each particle simply by: 1) looking at w…
One thing that shocked me about cancer treatment is how little they asked me about environmental factors. I assumed there would be questionnaires asking about all kinds of specific products and foods, maybe even asking for soil and water samples from my home. But there was none of that, and this was a major research hospital. The only thing was that they asked permission to use my biopsy for additional research. I kn…

No, here is a link between car fumes and lung cancer in mice. Unless you routinely have a car running in your kitchen while cooking (for mice), it's not related. PM2.5 particles are not all the same, nor are periodic exposure levels in a household kitchen in any way comparable to those used in a laboratory animal study. > For what it's worth, the same particulate counter will also spike off the charts when anyone tak…
You're not wrong... but running a vent or opening a window while you're cooking to mitigate PM2.5 exposure, which we know can be carcinogenic, seems like incredibly minimal intervention. I'd rather change my behavior slightly than wait for more conclusive data in this specific case.
It's probably not a bad idea to open a window or run a vent (depends on where you live, I guess), but I wouldn't panic or deploy a particle meter, or stop cooking if I couldn't do it, either.

Didn’t we know this in the 1970’s?

Willingness over your lifespan to reduce car use is not merely "because they're getting old", but rather directly correlated with a city's existing transit infrastructure. I've been able to spend a few weeks here and there in London or other transit-dense cities, and I just about never desire a car there, but I do in the states. Government leaders in the states can't imagine this reality or, if so, can't imagine it c…
And honestly, I take it back, there are nearly as many older folks punching for changes to city design to allow waking and bikes as young people. But in genera the older generations have the time and money needed for local political involvement in a way that younger generations do not, so we tend to get a future shaped by those who do not want change from the status quo (which is a radical departure from the eta of urban growth focused on cars).

Slightly? I barely use the brakes ever. Whoever is out braking in their EV all the time should have their DL revoked

A lot of it is from the natural gas combustion, but the food itself also contributes. The day I got an air quality sensor (to assess risk from wildfire smoke), I realized that my kitchen is basically an asthma factory for the kids. (I haven't actually assessed the risk from that, as its different from wildfires smoke, but j just keep the kids out of the kitchen now until the air clears)
I have some air filters with air quality sensors on them, and we have an electric range so there's no natural gas combustion happening. Often when cooking (pan frying especially), those sensors will max out and send the air filters into turbo mode for a good while.
