“…The present authors have reported the multielement determination of major-to-ultratrace elements in the dissolved fraction of natural water [17][18][19] and sediments 20,21 by ICP-AES and ICP-MS (inductively coupled plasma mass spectrometry). In the present experiment, then, the analytical methods developed in these previous studies were applied to the multielement determination of major-to-ultratrace elements in the particulate fractions with different particle sizes as well as in the dissolved fraction.…”

In order to elucidate the distributions of the elements among the particulate and dissolved fractions in pond water, majorto-ultratrace elements in different sizes of particles as well as in the filtrate passed through the 0.05 µm filter were determined by inductively coupled plasma atomic emission spectrometry (ICP-AES) and inductively coupled plasma mass spectrometry (ICP-MS). The different sizes of particle samples (ca. 100 -300 µg each) were collected on the membrane filters with pore sizes of 10, 3.0, 1.2, 0.4, 0.2 and 0.05 µm, respectively, by sequential fractionation. As a result, about 40 elements in different sizes of particles could be determined by ICP-AES and ICP-MS, after acid digestion using HNO3/HF/HClO4. Then, the fractional distribution factors of major-to-ultratrace elements among the particulate and dissolved fractions were estimated from the analytical results. The total contents of Al, Fe, Ti, REEs (rare earth elements), Bi, Pb and Ag in the particulate fractions (larger than 0.05 µm) were more than 80 -90%, while those of Ca, Sr, Cs, W, Ba, Mn and Co in the dissolved fraction, which corresponded to the filtrate passed through the 0.05 µm membrane filter, were more than 80%. It was further found that the fractional distributions of Cu and Zn in the dissolved fraction were ca. 50%. In addition, the enrichment factors (EFs) of the elements in the particulate fractions with particle sizes of 3.0 -10 µm and 0.05 -0.2 µm were estimated to elucidate their geochemical characteristics in natural water.

“…2 Furthermore, in the 1990s, inductively coupled plasma mass spectrometry (ICP-MS) has been developed as a highly-sensitive analytical method with excellent analytical features, such as low detection limit, wide linear dynamic range, and multielement detection capability. 6,7 Therefore, the present authors have demonstrated the multielement determination of major-to-ultratrace elements in various geochemical, biological, and environmental samples with the use of both ICP-AES and ICP-MS. 2,[8][9][10][11] In the present paper, hence, the multielement determination of major-to-ultratrace elements in the plant samples (plant reference materials) by ICP-AES and ICP-MS has been investigated in order to establish an analytical method for multielement analyses of the plant samples. Furthermore, the enrichment factors (EFs) for about 40 elements in plant reference materials were estimated from their concentrations with comparisons to the soil abundance data.…”

The multielement determination of major-to-ultratrace elements in plant reference materials (SRM Pine Needles, SRM Tomato Leaves, and NIES Tea Leaves) was carried out by ICP-AES (inductively coupled plasma atomic emission spectrometry) and ICP-MS (inductively coupled plasma mass spectrometry). The plant sample was decomposed with nitric acid and hydrofluoric acid in a Teflon beaker on a hot plate. The digest was dissolved in 1 M HNO3 solution, and then subjected to elemental analyses. As a consequence, the analytical data for about 40 elements including rare earth elements (REEs) were obtained over a wide concentration range, for example, from 49600 µg g −1 of Ca to 6.2 ng g −1 of Lu in Tomato Leaves. The enrichment factors, which were estimated by normalizing the observed concentrations of analyte elements in plant reference materials to their soil abundances, were evaluated in order to discuss the relative abundances of various elements between plants and soil. It was found that most of the elements, except for REEs in Pine Needles and Tea Leaves, were significantly accumulated in the plant reference materials. In particular, the essential elements (K, Mg, Ca, Mn, Cu, Zn, B and P) for plant growth provided large enrichment factors.

“…It is best to avoid using hydrochloric acid as it forms many polyatomic ions that are known to be interferences (see Table 2). Only acid extraction with nitric and perchloric acids in combination with hydrofluoric acid [38,39,42−45] or the use of alkali fusion with lithium metaborate [46] gives quantitative digestion recoveries across the range of trace elements commonly measured in sediments. However, using extraction procedures in which the complete dissolution of matrix elements occurs requires a careful choice of plasma operating conditions and careful consideration of potential polyatomic interferences when using a single quadrupole ICPMS to obtain accurate measurements.…”

The strengths and weaknesses of using inductively coupled plasma mass spectrometer (ICPMS) measurements of samples in solution for marine environmental analyses using real world examples is discussed. ICPMS can detect nanogram per litre concentrations of trace elements but suffers from polyatomic interferences generated from the sample matrix. Most of the routine trace elements measured in marine biological tissue and sedimentdigests, with the notable exceptions of iron, chromium, vanadium, and selenium, are not subject to severe interferences. Low recoveries of trace elements from sediments are due to the inability of extraction acids to remove trace elements such as chromium and nickel from sediment matrices. The use of ICPMS offers the advantage that elements such as phosphorus, which previously required elaborate digestion procedures and a colorimetric determination, can be rapidly determined using nitric acid digestion alone. The use of flow injection coupled with ICPMS allows on-line preconcentration of trace metals and metalloids using chelation by ion-exchange resins or hydride generation and trapping as well as separation from matrix elements. Thus, the routine determination of trace elements and inorganic and methylated arsenic, antimony, mercury, and germanium species in open-ocean waters is possible. The coupling of HPLC and GC to ICPMS allows the measurement of metal and metalloid species in biological and sediment extracts. However, extraction of unaltered species from matrices presents a challenge. Many of the species found in the environmental samples are not known and analytical standards are not available. The concurrent use of HPLC-MS is needed to confirm these species.
