Mercury is the chemical used by Quarm and other small scale gold
miners in extracting the gold they sell to prospective buyers who intend
to trade the precious mineral to gold companies.
Mercury may be an efficient chemical in the gold mining process but
it is also lethal, according to Michael Ali, principal programmes
officer of the Mining Department of the Environmental Protection Agency
(EPA).
He said the effect of mercury is long-term.
