>> While electric cars may help a bit, rubber from breaking and tyres is an issue In what way are they an issue? Tyre emissions are around 1/20th of the PM2.5 ejected from the exhaust and the airborne proportion is even smaller. Edit: "Committee on the Medical Effects of Air Pollutants" has a fairly non-commital "needs more study" finding but they did say "Non-exhaust particulate matter (PM) emissions, ie from brake wear, tyre wear, road surface wear and re-suspended road dust currently comprise just under 10% of UK primary particulate emissions and they are expected to become proportionately more important, as vehicle exhaust PM emissions from road transport are expected to decrease over the coming years" https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/917308/COMEAP_Statement__on_the__evidence__for__health__effects__associated__with__exposure_to_non_exhaust_particulate_matter_from_road_transport_-COMEAP-Statement-non-exhaust-PM-health-effects.pdf https://assets.publishing.service.gov.uk/government/uploads/...

Also PM2.5 is easy to filter out. Any cheap device can filter it out quite efficiently. For NO2 I tried all the most expensive devices, and none of them worked :(

  This might be a silly question, but how would you filter stuff "emitted" by tyres?

    I'm not a scientist, just an asthmatic person. All I can tell you is that I am so far not sensitive to electric cars at all. Regarding PM2 and NO2, I bought decices to measure them, that's why I have these results.

New research is also showing that type particles are a far bigger source of pollution in waterways than anyone seems to have expected, both in particulates and dissolved chemicals.

That is super interesting, I had no idea. Never even heard the word combo "tyre emissions" before. Thanks for sharing!
