Caribou, which rely on lichens as forage, are a dietary source of monomethylmercury (MMHg) to many of Canada's Arctic Aboriginal people. However, little is understood about the sources of MMHg to lichens in the High Arctic. We quantified MMHg, total mercury (THg) and other chemical parameters (e.g., marine and crustal elements, δ(13)C, δ(15)N, organic carbon, calcium carbonate) in lichen and soil samples collected along transects extending from the coast on Bathurst and Devon islands, Nunavut, to determine factors driving lichen MMHg and THg concentrations in the High Arctic. Lichen MMHg and THg concentrations ranged from 1.41 to 17.1 ng g(-1) and from 36.0 to 361 ng g(-1), respectively. Both were highly enriched over concentrations in underlying soils, indicating a predominately atmospheric source of Hg in lichens. However, MMHg and THg enrichment at coastal sites on Bathurst Island was far greater than on Devon Island. We suggest that this variability can be explained by the proximity of the Bathurst Island transect to several polynyas, which promote enhanced Hg deposition to adjacent landscapes through various biogeochemical processes. This study is the first to clearly show a strong marine influence on MMHg inputs to coastal terrestrial food webs with implications for MMHg accumulation in caribou and the health of the people who depend on them as part of a traditional diet.

“…CR was chosen because it is abundant and often forms a carpet on the ground among shrubs (Fig. 1c) in the region, and it was studied in the biomonitoring research in Arctic [23], Norway [24], Russia [25][26][27], Japan [28], and Canada [29]. The collection area was restricted to 10,000 m 2 to minimize the potential effects of local microhabitat variations on the lichen element composition.…”

“…This conclusion is also supported by a comparison of our data with those from the other lichen biomonitoring studies conducted in remote sites, such as Usnea subfloridana from Canada [32], severally lichens from the France [33] and Arctic regions [34], Usnea sp. from the forest-grassland regions of Chile [35], Cladonia rangiferina and C. stellaris from the remote sites of Russia [24,27], epiphytic lichens from Italy [10,[36][37][38][39] and France [40], and several lichens from Inner Mongolia, China [41,42].…”

Lichen element compositions are of a reliable tool for the biomonitoring of atmospheric element deposition. The zoning and patterned accumulation of elements in lichen thallus is one of the important factors influencing lichen element concentrations. We collected an epigenous fruticose lichen Cladonia rangiferina (CR) from a remote site of Huzhong National Natural Reserve, Heilongjiang, NE China. Fifty-five elements (Ag,
