Where does dust derive from? ...

How do you carry surrounded by the cleaning...
Answers:    Dead skin cells, molds, inorganic toxins, settled environmental pollution, decaying bug particle, tiny bugs and their excrement and blowing dirt particles. And, if you hold a pet, add animal dander and more unresponsive skin cells.

When you judge about it - yuk...

Okay, I'll be fund. I think I hold an urge to dust again...
What's the best sweeper?
I can't tell you where on earth it comes from but I can tell you where on earth it is:
all over my black bookshelf :-)
