The material transport from rivers to the ocean constitutes an important part of the cycle of marine elements. However, most attention has been focused on the impact of fluvial dissolved matters on the balance of marine elements. For most elements, the role of terrestrial particulates is currently less appreciated and quantified. Prof. Zhao Ning from the State Key Laboratory of Estuarine and Coastal Research of ECNU (SKLEC), in cooperation with scientists from National University of Singapore, Massachusetts Institute of Technology and other institutions, revealed that the boundary exchange between terrestrial particulates and seawater is an important link in the global marine lead (Pb) cycle, which can explain the missing flux of lead source-sink imbalance in seawater. The related paper was published online recently in theProceedings of the National Academy of Sciences(PNAS) with the title “Boundary exchange completes the marine Pb cycle jigsaw”.
