Long-term monitoring of atmospheric pollution in the Maritime Antarctic with the lichen Usnea aurantiaco-atra (Jacq.) Bory: a magnetic and elemental study
Abstract Antarctica is a natural research laboratory thanks to its unique climate, geography, flora and fauna. The conservation of Antarctica's environment is monitored through the Madrid Protocol; however, there are local pollution problems associated with human activities such as research and...

Abstract Antarctica is a natural research laboratory thanks to its unique climate, geography, flora and fauna.
