- Abstract
- Within the framework of the Ev-K2-CNR research program of the Italian
National Research Council a specific task project has been initiated for
the identification of trace elements in lichens in remote high altitude
areas.
This is to evaluate the possibility of using lichens as biomonitors of
trace elements of atmospheric pollution.
In this preliminary study, more than 20 elements havebeen determined in
some species of lichens collected at different altitudes (from 1300 to
5000 in) in the region of the Sagarmatha National Park (Nepal). Samples of
superficial soils were also collected and analyzed to calculate the trace
element enrichment factors (EF) using scandium as a normalizing element.
Most of the trace elements were determined by instrumental neutron
activation analysis (INAA), while lead and cadmium measurements were
carried out with electrothermal atomic absorption spectroscopy (ET-AAS).
The EF values as well as the elemental concentrations are reported and
discussed.
