Tracking human footprints in Antarctica through passive sampling of polycyclic aromatic hydrocarbons in inland lakes
Freely dissolved polycyclic aromatic hydrocarbons (PAHs) were monitored in seven inland lakes of Antarctica by a polyethylene (PE)-based passive sampling technique, with the objective of tracking human footprints. The measured concentrations of PAHs were in the range of 14-360 ng L-1 with the highes...
