A significant portion (at least 80%) of the mercury in batteries is
volatilized during use.
The ionic mercury left in the air depolarized battery at disposal poses
some potential risk to human health, but has a high dissolution rate and
has probably already disappeared from the environment.
The remaining elemental mercury dissolves so slowly that its impact is
likely to be minimal.
