Pollutant Concentration in Runoff at McMurdo Station, Antarctica
Accidental spills and chemical contamination from leaking fuel and materials (lubricants, paints, etc.) at McMurdo Station have caused environmental concerns, and snowmelt runoff may tend to transport these contaminants. Therefore, the objective of our study was to quantify the pollutant types and l...
