TY - T1 - Sources and fate of mercury in aquatic ecosystems SN - 952-11-1397-9 / 1796-1661 UR - http://hdl.handle.net/10138/39340 T3 - Monographs of the Boreal Environment Research 23 A1 - Porvari, Petri A2 - PB - Finnish Environment Institute Y1 - 2003 LA - en AB - Deposition, catchment runoff concentrations and fluxes, lake water concentrations of total mercury (TotHg) and methyl mercury (MeHg), and potential Hg methylation in different compartments of boreal ecosystem and TotHg concentrations of fish in boreal and tropical reservoirs were studied. The results provide new knowledge of behaviour and cycling of Hg for Hg pollution protection policy. Anthropogenic and natural Hg emissions have led to increased Hg deposition and further accumulation of Hg in ...
