Progress on understanding atmospheric mercury hampered by uncertain measurements

Mercury (Hg) is a potent neurotoxin and globally reducing

environmental levels is seen as paramount for protecting

human and wildlife health. In 2013, many countries finalized the

negotiations on, and have now signed, the Minamata Convention

on Mercury, which commits participating countries to reduce

emissions and use of mercury. Successful implementation of the

treaty will require adequate verification through globalmonitoring.
