Lunar regolith is nasty stuff - essentially tiny obsidian shards, and the Apollo astronauts had nothing like decent decon on the LEM. Did they have health problems that arose from that? Obviously, Buzz is still kicking around.
I have heard the on some Apollo missions the "dust got everywhere" ,"was very difficult to control", and "smelled like gunpowder". Also, when the Apollo astronauts were observed when they returned and they did have some symptoms that appeared to be from the lunar dust exposure; but, the dust exposure symptoms did not appear to be chronic.
Note: There were a LOT of nasty things the Apollo astronauts got exposed to in space as they were away from all the things on earth that our bodies depend on (like gravity and the atmosphere). If they did have long term affects from lunar dust, it could be very difficult to tease that out from all the other problems.
The book "The Cosmic Compendium: Space Medicine" has a whole section on Lunar Dust and does state that the "Apollo astronauts seemed to tolerate lunar dust".
