On a trip in 2017, researchers from Queen’s University found elevated mercury levels within an edible mushroom species. In the summer of 2018, researchers assessed multiple plant species and fungal species for elevated mercury concentrations. The literature has shown that mushrooms, especially puffballs bioaccumulate mercury within their fruiting bodies and may transfer it to high trophic levels through consumption. The main objectives for my Masters of Environmental Studies research from Queen's University in 2019 are to sample different locations within Iqaluit over a 14 day period from July 31 to August 14, 2019 in order to: 1) sample additional plant species that were not collected in 2018 and identify their potential to accumulate mercury, 2) sample in depth fungi species with a focus on puffball species that were found to accumulate high levels of mercury from the 2018 sample collection, 3) collect corresponding fungal mycorrhiza and soil samples to determine if the mercury is being accumulated from the soil or the atmosphere. With help from the Nunavut Research Institute (NRI) and local community members taking the Environmental Sampling and Analysis Training Program offered by the Iqaluit Analytical Services Unit (IASU), direct mercury analyzers will be used to test the selected plant, fungi and soil samples for total mercury concentrations. Data will be compiled and statistically analyzed at Queen’s University. Additionally, further insight into additional plant species, with a focus on edible fungi and corresponding soil samples will give insight into the impact this contamination may pose on the health of local human and wildlife population and the main source of this mercury contamination. Although this project is a continuation of the project from 2018, this is the first NPC application being completed because we require soil samples in this year’s study. Previous years only required sampling plant species and therefore no NPC applications were required.
