abstract = {Laser ablation inductively coupled plasma mass spectrometry
(LA-ICP-MS) was used for quantitative imaging of toxic and
essential elements in thin sections (thickness of 30 or 40
pm) of tobacco plant tissues. Two-dimensional images of Mg,
Fe, Mn, Zn, Cu, Cd, Rh, Pt and Pb in leaves, shoots and
roots of tobacco were produced. Sections of the plant
tissues (fixed onto glass slides) were scanned by a focused
beam of a Nd:YAG laser in a laser ablation chamber. The
ablated material was transported with argon as carrier gas
to the ICP ion source at a quadrupole ICP-MS instrument. Ion
intensities of the investigated elements were measured
C-13(+), S-33(+) and S-34(+) together with and within the
entire plant tissue section. Matrix matching standards
(prepared using powder of dried tobacco leaves) were used to
constitute calibration curves, whereas the regression
coefficient of the attained calibration curves was typically
0.99. The variability of LA-ICP-MS process, sample
heterogeneity and water content in the sample were corrected
by using C-13(+) as internal standard. Quantitative imaging
of the selected elements revealed their inhomogeneous
distribution in leaves, shoots and roots. (C) 2008 Elsevier
