PFAS Concentrations in Lake Hazen Water and Snow, 2012-2015

Concentrations of perfluoroalkyl substances (PFAS) sampled in water and snow for Lake Hazen, Nunavut, Canada. The dataset was produced by researchers including MacInnis et al. and published in 2019. Snow samples were collected from 2013-2014, and water samples were collected over a time span of 2012-2015.

Use Cases

• Analyze atmospheric deposition patterns of PFAS based on snowpack concentration data mentioned in the description
• Study the fate and transport of perfluoroalkyl carboxylic acids (PFCA) based on odd-even concentration ratios characteristic of long-range transport
• Model contaminant cycling in High Arctic lakes based on multi-year water sample data from 2012-2015
• Assess the contribution of annual atmospheric deposition as a PFAS source based on the comparative analysis of snow and water samples

Strengths

• Multi-year temporal coverage with snow samples from 2013-2014 and water samples from 2012-2015
• Data is associated with a peer-reviewed publication in Environmental Science & Technology (2019)
• Specific geographic focus on Lake Hazen, a High Arctic lake on Ellesmere Island, Nunavut

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic/temporal bias inherent to a single Arctic lake study
