It doesn't leave the body I don't think. Might explain you crabbiness !I helped do some work on the indoor range at my gun club. I was wearing a mask, but apparently not well fitted. My blood lead levels were significantly elevated afterwards, enough that my doctor was concerned. i will now no longer do such work on an indoor range -- I've got enough health problems already.
Edited to add: years later, my blood lead levels were still elevated.
