At least the brown is more of an indication of the particulate pollution caused by cars...I suspect what you're looking at there is particle-ized tires and brake pads, and a bit of soot from diesels. If we're lucky, maybe some sand from sanding roads instead of salting.
But yes, the city should be more careful with the salt it uses, but at least it has control over the salt it uses. The only thing it can do about homeowners is beg them not to pour tons of salt on sidewalks, which some people do...of course, that begging also leads other people to use not enough salt meaning we end up with dangerous sidewalks as well.
The current system is pessimal in almost every way.
