Florescent light broke and I may have been exposed to the dust?

Hi, Me and a friend were cleaning a room out today, and in the process, a long florescent light fell and broke and a bunch of dust, phosphorus and mercury right? came out of the bulb, i was about 3 feet away from it, but would remaining in the room after the small "cloud" dissipated visually still be exposing us to any of the toxins? There was a small window open, but wasn't offering amazing ventilation, anything to be worried about? (Even if a person did accidentally inhale the cloud directly, would there be any adverse health affects?)
