Overview

High-resolution analysis reveals increasing mercury accumulation in Greenland due to human and natural factors.

Key Points

  • To understand the effects of anthropogenic activity on mercury cycling during the Holocene.
  • Analyzed a high-resolution Greenlandic ice core record
  • Measured mercury concentration and accumulation flux over the Holocene
  • Evaluated impacts of volcanic eruptions and climate changes
  • Mercury accumulation has significantly increased since the 13th century, aligning closely with anthropogenic emissions
  • Earlier periods showed continuous increases in mercury accumulation before the 13th century
  • Findings suggest that human activity influenced Greenlandic mercury cycling much earlier than previously understood
