Isn't most of the dangerous dust particles a by-product of car emissions? I don't think dirt would that dangerous anyway (obviating asthma).

- partycoder 9y agoMost comes from emissions, yes. But most emissions may not come from cars, that distribution depends on the city. Some cities allow wood fueled appliances, some cities allow burning trash, some cities have a strong industrial presence, some cities have coal thermal power plants, etc.
