Overview

Research demonstrates stable mercury levels in seagrass sediments over millennia, highlighting the role of biogeochemical processes.

Key Points

  • Mercury concentrations remained stable from 100 to ∼1880 CE in coastal WA, suggesting minimal human impact during that period.
  • Seagrass sediments reveal a record of historical mercury fluctuations, impacting our understanding of both human and natural mercury cycles.
  • Enhanced organic carbon accumulation contributed to increased mercury levels since European settlement, rather than rising external mercury sources.
  • The study emphasizes the importance of seagrass meadows as natural paleoarchives for tracking long-term contamination in coastal environments.
