When I lived in Mexico, I understood where dust came from. There was dry, dusty soil exposed nearly everywhere. Vegetation was the exception in the sierra. So, there dust was soil particles. [I carefully didn’t think about the minority of other kinds of particles mixed into it.]
That dust source isn’t a big thing here in urban-suburbia. So, where does dust come from? Is it mostly teensy bits of textile fiber? And what else?
Okay, I’m finished with that topic….
