Atmospheric deposition is an important source of trace elements (TEs) to the Arctic,
including both anthropogenic (eg, Pb) and micronutrient (eg, Fe) metals. This study
measured TE loadings, Pb isotopes, and dissolution in aerosols collected at Alert, Nunavut,
Canada, from spring to summer of 2013 and 2014 and during the Canadian Arctic
GEOTRACES Cruises (GN02 and GN03) in the summer of 2015. The aerosol loadings were
5–8 times higher and more enriched with anthropogenic metals (Pb and Cd) in the spring …
