Our results show that river export is the largest source of mercury to coastal oceans worldwide, and continued mercury risk modelling should incorporate the impact of rivers.ĭriscoll, C. We estimate that the river mercury export could be responsible for a net annual export of 350 (interquartile range: 52–640) Mg mercury across the coastal–open-ocean boundary, although there is still high uncertainty around this estimate. Coastal oceans constitute 0.2% of the entire ocean volume but receive 27% of the external mercury input to the ocean. Furthermore, high flow events, which are becoming more common with climate change, are responsible for a disproportionately large percentage of the export. We find that rivers annually deliver 1,000 (minimum–maximum: 893–1,224) Mg mercury to coastal oceans, threefold greater than atmospheric deposition. Here we construct an unprecedented high-spatial-resolution dataset estimating global river mercury and methylmercury exports. Nevertheless, new regional research has noted that the riverine mercury export to coastal oceans may also be significant to the oceanic burden of mercury. Recent global mercury cycling and risk models attribute all the mercury loading to the ocean to atmospheric deposition. Worldwide, coastal fisheries contribute the majority of human exposure to mercury through fish consumption. Mercury is a potent neurotoxic substance and accounts for 250,000 intellectual disabilities annually.
