A 1 µm dust grain sitting one light year from such a blue supergiant could be pushed out to two light years in about 10,000 years.
Yes. And every energetic photon that hits that particle has the possibility of dissociating an atom from it. Most won't, but it's a process that will occur. High energy charged particles even more so.
