Determination of Trace Elements by INAA in Urban Air Particulate Matter and in Transplanted Lichens
Articolo
Data di Pubblicazione:
2005
Abstract:
Lichens as biomonitors and neutron activation analysis as analytical technique have been employed to evaluate the trace element atmospheric
pollution in the metropolitan area of the city of Pavia (Northern Italy). Transplanted lichens (Parmelia sulcata and Usnea gr. hirta) and air
particulate matter have been monthly collected and analyzed during the winter 2001 2002. INAA and ET-AAS have been used for the
determination of 28 elements in air particulate matter and 25 elements in lichens. Trace metals concentrations as well as the corresponding
enrichment factors were evaluated and compared.
