I've seen adverts for Chinese luxury apartments touting the built-in HEPA filtration systems. Seems to be a must-have if the air outside is polluted. Nobody seems to even think about this in building codes in the West. Especially, as you say, for apartments near major roads.
Filtration is a very good idea. HEPA filtration for residential use is dumb. A HEPA filter must remove at least 99.97% of aerosols 0.3μm in diameter. A filter which removed 99% and blows air 1% faster will remove just as much, or one which removes 50% and blows air twice as fast. For recirculating air, all of those accomplish the same thing. Some of those have much higher noise, running costs, and general upkeep than…

Only very small piston airplanes, and the need fuel is being phased out. Areas immediately surrounding heavily used ga airports are occasionally seeing elevated levels but it's not a particularly potent source for the public. The issue is mostly employees at the airport being exposed while fueling and performing maintenance.
why are they still using it?

Unfortunately buses and trains are only viable above a certain density, and many communities exist configured in such a way that they are intentionally low density. While metal mining might have an environmental impact, abandoning millions of existing homes and building new ones in cities not only also has a large environmental impact (concrete also isn't great for the environment), but it is also politically, econom…
Busses are viable as long as you make them viable. If you have a busstation at a 1 km distance you can make it viable in most places even with the mega sprawl of the US. The economical incentives of a car economy is perverse it is the tradgedy of the commons distilled.
Have you used bus systems in the US? Even in cities that have made a large investment in bus service, it can be a challenge.

Translation: you have no coherent response to what I said, and don't like that, so you figured a bit of snark might recover some dignity. It's better to simply not reply.
I gave you my argument in detail above with sources that companies routinely collude in anti-consumer ways, but you decided to strick your fingers in your ears and sing "lalala I don't believe you" . Therefore I have no more replies for you to protect my sanity. Feel free to believe whatever you want to believe, just leve me be, i have no duty to waste my time to change your opinion of something you're fixated on.
Was this your link that said "there was a cartel in an industry once"? That doesn't seem to demonstrate a general issue.

Electric cars can help with some of the problems but don't solve all of them. In the case of brake dust specifically, presumably electric cars are worse because they're quite a bit heavier than ICE cars.
What you're saying is completely true for tire particulates, but if you drive an electric car normally you're almost never engaging the brakes. Since almost all normal amount of braking is in the envelope of where your regeneration braking can take all of the power. This counts even for hybrids though. A friend of mine had to replace his brakes after over 10 years and 180,000km on his Prius for the first time. Not be…

This definitely demonstrates that there's a brake pad cartel, right now, doing the same thing. By implication, you see.
The credibility and purpose of the article was shot down when they said the problem would be getting WORSE with EV's. Firstly, the problem becomes less of an issue with EV's and they shared no evidence to support that moving to EV's would increase non-exhaust based pollution. Lastly, there have been plenty of studies over the last two decades which show charged particles from car brakes.
EVs are 50%-100% heavier and a lot of them accelerate faster than supercars from the 80s...
A Corolla sedan is +30% weight over a model 3.

I don’t think this is a 1:1 comparison though. Electric cars can utilize regenerative braking, which can significantly slow them down before needing to use friction from brake pads in order to stop.
A startup I worked for years ago initially had a temporary office in a coworking space that catered to artists and craftspeople, in a renovated warehouse near the freeway loop downtown. They didn't have air conditioning, which isn't particularly strange in the PNW, but we did learn opening the windows for breeze was a very bad idea. The amount of tire and brake dust/soot that would pile up in a single afternoon was d…
