Preliminary data on enviornmental distribution of mercury in northern Victoria Land, Antarctica
Concentrations of mercury were measured in soil and two species of epilithic macrolichens ( Umbilicaria decussata and Usnea antarctica ) collected along of the coast of northern Victoria Land coast. Most of the soil samples had a very low mercury content, whereas lichens had levels higher than in ot...

Summary: | Concentrations of mercury were measured in soil and two species of epilithic macrolichens ( Umbilicaria decussata and Usnea antarctica ) collected along of the coast of northern Victoria Land coast. Most of the soil samples had a very low mercury content, whereas lichens had levels higher than in other remote areas. Although a possible contamination of samples cannot be completely excluded, the relevance to bioaccumulation of the very slow growth rate of lichens and of volcanic activity are discussed. |
