Overview

• Dragonfly larvae collected from 150 National Parks show unique mercury contamination patterns.
• Mercury deposition varies: in dry regions, it comes from rain and snow, while in wet areas, it sticks to leaves.
• Dragonflies are a cost-effective and widespread indicator of mercury, even in arid regions where fish are scarce.
• The study's findings could influence global mercury monitoring strategies under the Minamata Convention.
• Public participation in the Dragonfly Mercury Project enhances scientific research and environmental awareness.
