it's tires and brake dust.

  In a city, its simply a combination of everything. Tires and brake dust are a small part of overall vehicle emissions. Local industry, and whatever else is on fire, are also big contributors to air pollution.

    Tires and brake dust are an overwhelming majority of vehicle emissions however. When I see people this confidently wrong I always wonder if its a language model now.

      "Large trucks are biggest culprits of near-road air pollution" So black carbon from diesel truck exhaust (and buses) pollute a lot more than a lot of you think. They call it a 'soup' of pollution of both exhaust and tires. But you should continue to be skeptical of AI driven thought-content :) Sources: https://www.sciencedaily.com/releases/2018/09/180910111237.htm https://www.sciencedaily.com/releases/2018/09/180910111237.h... https://news.engineering.utoronto.ca/national-air-pollution-report-calls-out-rush-hour-traffic-diesel-truck-emissions-as-major-areas-of-concern/ https://news.engineering.utoronto.ca/national-air-pollution-... https://www.socaar.utoronto.ca/wp-content/uploads/2019/12/NearRoadAirPollution.pdf https://www.socaar.utoronto.ca/wp-content/uploads/2019/12/Ne...

    local industry is all outside the cities here. Balconies on the other side of the building don't have this. It;s directly from the cars.
