The Dragonfly Mercury Project: Assessment of Mercury Risk in US National Parks Through Citizen Science

Learn about the Dragonfly Mercury Project (DMP) in this conference talk examining mercury bioaccumulation in US National Parks through citizen science initiatives. Explore how dragonfly larvae serve as biosentinels across 450 sites in 100 protected areas, with findings showing mercury concentrations varying from 10.4-1,411 ng/g across different habitats. Discover how lotic habitats contain up to 1.8-fold higher mercury levels than lentic habitats, and locations with wetlands show 37% higher concentrations. Understand the correlation between dragonfly mercury levels and those found in fish and amphibians, demonstrating their effectiveness as indicators of mercury bioavailability in aquatic food webs. Examine the developed impairment indices that assess potential mercury exposure risks to fish, wildlife, and human health, revealing that while most sites show moderate to low risk, 12% face high or severe risk levels. Gain insights into this landmark study that combines rigorous scientific research with citizen engagement and education to understand mercury pollution risks in protected areas.
