Nature Communications, Published online: 05 May 2026; doi:10.1038/s41467-026-72058-8 Paleo-depositional history and hydrogeological evolution fundamentally dictate microbial. landscapes and groundwater quality in the Pearl River Delta. This study links ancient sedimentary processes to modern-day ammonium dynamics in global deltas.
