Atmospheric emission and deposition of mercury(Hg),a toxic metal of global concern,has been long considered to control environmental Hg levels in water,soil,sediment,and ultimately fish,which is the major exposure source for humans.In the last two decades,a number of studies of varying spatiotemporal scales and approaches have shown that fish Hg,particularly in lakes and open oceans,is positively and linearly correlated with atmospheric Hg deposition through both dry and/or wet deposition[1-3].
