Because of the high toxicity of mercury, both the mining of cinnabar and
refining for mercury are hazardous and historic causes of mercury
poisoning. In particular, the Romans used convict labor in their mines
as a form of death sentence. The Spanish also used shorter term convict
labor at the Almaden mines, with a 24% overall fatality rate in one 30
year period.
Abandoned mercury mine processing sites often contain very hazardous
waste piles of roasted cinnabar calcines. Water runoff from such sites
is a recognized source of ecological damage.
