Trends of lead and zinc in resident and transplanted Flavocetraria nivalis lichens near a former lead-zinc mine in West Greenland
This study investigated spatial and temporal trends of lead (Pb) and zinc (Zn) in resident and transplanted Flavocetraria nivalis lichens near the former Black Angel Mine in Maarmorilik, West Greenland. The objectives of the study were to evaluate resident and transplanted lichens for monitoring dus...
