资源简介：
The Dragonfly Mercury Project measures biological mercury exposure in waterbodies across the US, with emphasis on protected lands managed by the National Park Service, US Fish & Wildlife Services, Bureau of Land Management, and USDA Forest Service. The annual interactive data summaries report the distribution and patterns of mercury concentrations in dragonfly larvae from each participating management unit (e.g. national park unit, national wildlife refuge), during the 2021-22 sampling seasons.
