Abstract
En 中文
• Upper saline plume dilutes/mixes arsenic before seaward export. • Intertidal sediments efficiently trap arsenic from fresh SGD. • Redox, competition, co-precipitation control As mobility across scales. • RSGD, not fresh SGD, is the dominant pathway for terrestrial As export. • SGD delivers more As to sea than rivers, refining regional As budgets.
