Concentrations of perfluoroalkyl substances (PFAS) sampled in water and snow for Lake Hazen, Nunavut Canada

The delivery of perfluoroalkyl substances (PFAS) from snowpacks into Lake Hazen, located on Ellesmere Island (Nunavut, Canada) indicates that annual atmospheric deposition is a major source of PFAS that undergo complex cycling in the High Arctic. Perfluoroalkyl carboxylic acids (PFCA) in snowpacks display odd-even concentration ratios characteristic of long-range atmospheric transport and oxidation of volatile precursors. This Dataset contains the concentrations of perfluoroalkyl substances (PFAS) in Arctic water and snow for Lake Hazen. Snow samples were collected from 2013-2014, water samples were collected over a time span of 2012-2015. Citation: MacInnis, J. J., Lehnherr, I., Muir, D., St Pierre, K. A., St Louis, V.
