C. Locatelli et al., NEW STANDARDLESS METHOD OF PB ANALYSIS BY ELECTROTHERMAL ATOMIC-ABSORPTION SPECTROSCOPY IN AIR AEROSOLS - COMPARISON WITH THE OFFICIAL METHOD, Applied spectroscopy, 50(12), 1996, pp. 1585-1589
A standardless analysis method with electrothermal atomization/ atomic
absorption spectroscopy (ETA-AAS) measurements is proposed and applie
d to the determination of Pb in an urban environment (Bologna, Italy)
and compared with results obtained in the same place and time, with th
e method dictated by Italian law, which is derived by European Communi
ty Directives, It was found that the difference previously observed be
tween the two methods is due to the low efficiency of the 0.45-mu m-po
re-size paper filters, dictated by the official method, The uncovering
of the error source validates the proposed method and highlights its
accuracy, Moreover, the two methods can be conveniently combined to gi
ve two series of data relevant to pollutants associated with low- and
high-dimension particles, This capability gives a much more precise pi
cture of the hazard of a pollutant.
