“…Although lead might be lost through feathers, it is possible for sequestered lead in bones to become active in the bloodstream and tissues again. McPartland et al [ 263 ] reported that common eiders breeding in the central Baltic Sea had increased levels of lead as the incubation period progressed. As the lead isotope ratios did not change throughout the incubation period and the eiders were fasting, lead was probably remobilising from the bones.…”

Understanding lead exposure pathways is a priority because of its ubiquitous presence in the environment as well as the potential health risks. We aimed to identify potential lead sources and pathways of lead exposure, including long-range transport, and the magnitude of exposure in Arctic and subarctic communities. A scoping review strategy and screening approach was used to search literature from January 2000 to December 2020. A total of 228 academic and grey literature references were synthesised. The majority of these studies (54%) were from Canada. Indigenous people in Arctic and subarctic communities in Canada had higher levels of lead than the rest of Canada. The majority of studies in all Arctic countries reported at least some individuals above the level of concern. Lead levels were influenced by a number of factors including using lead ammunition to harvest traditional food and living in close proximity to mines. Lead levels in water, soil, and sediment were generally low. Literature showed the possibility of long-range transport via migratory birds. Household lead sources included lead-based paint, dust, or tap water. This literature review will help to inform management strategies for communities, researchers, and governments, with the aim of decreasing lead exposure in northern regions.

“…After the pre-breeding foraging period when appropriate body condition has been met for breeding, female eiders undergo a uniparental 24-26 day incubation fast in which they mobilize their endogenous fat and protein reserves (Hanssen et al 2002;Bottitta et al 2003;Sénéchal et al 2011). During their incubation fast and as incubation advances from early to late stages, eiders release and circulate contaminants accumulated within their tissues that may influence incubation behaviour (Wayland et al 2005;Bustnes et al 2010;McPartland et al 2020). The effects of Hg could be further amplified by extreme air temperature and wind speed exposure during the incubation period by affecting metabolic rates of the incubating female (e.g., Fast et al 2007) and influencing rates of body mass loss and immune system functioning .…”

Dispersion of potentially toxic elements associated with efflorescent crusts and mine tailings materials from historical mine sites threaten the environment and human health. Limited research has been done on traceability from historical mining sites in arid and semi-arid regions. Pb isotope systematics was applied to decipher the importance of identifying the mixing of lead sources involved in forming efflorescent salts and the repercussions on traceability. This research assessed mine waste (sulfide-rich and oxide-rich tailings material and efflorescent salts) and street dust from surrounding settlements at a historical mining site in northwestern Mexico, focusing on Pb isotope composition. The isotope data of tailings materials defined a trending line (R2 = 0.9); the sulfide-rich tailings materials and respective efflorescent salts yielded less radiogenic Pb composition, whereas the oxide-rich tailings and respective efflorescent salts yielded relatively more radiogenic compositions, similar to the geogenic component. The isotope composition of street dust suggests the dispersion of tailings materials into the surroundings. This investigation found that the variability of Pb isotope composition in tailings materials because of the geochemical heterogeneity, ranging from less radiogenic to more radiogenic, can add complexity during environmental assessments because the composition of oxidized materials and efflorescent salts can mask the geogenic component, potentially underestimating the influence on the environmental media.
