Abstract
A vulnerable point of
the currently used approach to the search for the new species capable
of abnormal accumulation (hyperaccumulation) of trace elements is that
most studies have been conducted in laboratory conditions and focused on
the determination of a limited number of elements. We propose a
methodology that enables screening for multi-element accumulating
plants. This methodology is based on two analytical steps: a
semiquantitative analysis mode by ICP-MS that allows selection of plant
samples which are enriched in one or more trace elements, and a
quantitative analysis necessary for confirmation of the results derived
from the first step. The proposed methodology was tested in the study of
30 plant samples. Ten elements with the highest concentrations obtained
in the semiquantitative analyses were determined quantitatively with
the following detection limits (in mg/kg): 0.001 for Ag, 0.08 for Ba,
0.002 for Cd, 0.005 for Co, 0.01 for Cr, 0.003 for Cu, 1.4 for Fe, 0.012
for Mn, 0.03 for Ni, 0.006 for Pb, 0.001 for Sc, 0.001 for Tl and 0.06
for Zn. The CRM recovery values obtained were in the range of 80–103 %,
and the precision of the measurements (as RSD) was in the range of
0.34–4.05 %. We also propose a simple method for evaluation of typical
element concentrations in plants collected for analyses. Our approach
provides a novel screening method for both identification of new
hyperaccumulators and for studying a larger number of elements
accumulated by plants. This method may find its application in
environmental biotechnology. © 2014, The Author(s).
