Fig. 5.1 The scanning electron microscope (SEM) image shows debris (
white spots
) of environ-
mental or occupational origin deeply embedded in a lung tissue affected by adenocarcinoma.
Among silicon-based particles (b) there are also toxic Lead-Antimony-Zinc debris. In the
y
-axis of
the EDS spectra the intensity of the signal in counts is shown and in the
x
-axis the energy in keV
