Atmospheric Contaminant Deposition using Snowpack The data set includes snow samples (metals, water chemistry and polycyclic aromatic hydrocarbons [PAHs]). Data from 2012-2014 snowpack samples collected from ~90-130 sites located varying distances from the major oil sands development area show deposition patterns and levels consistent with earlier studies carried out in 2008 (Kelly et al. PNAS, 2009 and 2010). As with earlier findings, concentrations of numerous metals, water chemistry parameters (Ni, Pb, Zn, V, La, Al, Fe, total Hg, methyl Hg, total suspended solids [TSS], particulate organic carbon [POC], particulate organic nitrogen [PON], total phosphorus [TP]) and PAHs decrease with distance from the major mining extraction and upgrading facilities. Canadian Council of Ministers of the Environment (CCME) guidelines do not exist for snow. All data are subjects of a publication containing method details, full QA/QC, interpretations and conclusions. Citations: A. Dastoor, A. Ryjkov, G. Kos, J. Zhang, J.L. Kirk, M. Parsons, A.
