I live on a relatively busy road in the city, cars drive around 30km/h. Doesn't feel like a big road, but lot of cars during the weekdays. After cleaning, the white elements balcony turns black every 1.5 - 2 weeks. Dont know what it is, some people say tires. Whatever it is, it's a lot and living in cities like this have already shown a lower life expectancy of around 5 years.

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.

Do you happen to live near anyone making alcohol? "Whisky mold" is a thing. When people talk of black material forming so quickly it is an option to consider.

Try burning it if it catches fire it's synthetic rubber natural rubber doesn't burn but does make up 25% of tires. If the debris doesn't burn either natural rubber or brake dust or a mix. Modern brake pads are ceramic or metal but not asbestos anymore. But any burning of the dust would indicate synthetic rubber is present.
