    Aluminum (Al), manganese (Mn), cobalt (Co), and lead (Pb) are key trace elements in seawater and thus significant in chemical oceanography research. However, although all of these elements are highly scavenged in the ocean, only a few studies focus on the intercomparison of their distributions. Here, we report the basin-scale and full-depth sectional distributions of these elements observed during three GEOTRACES Japan cruises in the North Pacific. We confirmed that a surface maximum of the dissolved (d) species is not a common feature for the four elements and that the d species have the lowest concentrations in the Pacific Deep Water (PDW) as compared to other oceans. The elements showed different speciations and distributions. The fraction of labile particulate (lp) species was calculated as the difference between the total dissolvable (td) species and d species. The lpM/tdM ratio, where M refers to an element, is highest for Al, at 0.66 ± 0.31 (average ± sd, n = 489), and lowest for Pb, at 0.02 ± 0.08 (n = 575). Further, the distribution of each element is uniquely related to ocean circulation. The tdAl concentration is high in the Equatorial Under Current (EUC), the North Equatorial Current (NEC), and the Lower Circumpolar Deep Water (LCDW). Manganese is supplied from reductive sources such as sediments on the continental shelves around the northern boundary. Cobalt is concentrated in the North Pacific Intermediate Water (NPIW) and in the Equatorial Pacific Intermediate Water (EqPIW) owing to the combined effects of supply from the continental shelves, biogeochemical cycling, and scavenging. Lead shows a subsurface maximum centered at ∼35°N and ∼200 m depth, implying an association with the formation of the Subtropical Mode Water (SMW) and the Central Mode Water (CMW). Although the subsurface Pb maximum in the Atlantic has diminished over the last three decades owing to the ban on leaded gasoline use, it has been sustained in the North Pacific through the growth of other anthropogenic sources in Asia and Russia. We propose that the enrichment factor of dM, defined as EF(dM) = (dM/dAl)seawater/(M/Al)upper crust, where (M/Al)upper crust is the molar ratio in upper crustal abundance, can be a good parameter for the sources. The median is 1.3 × 102 (n = 436) for EF(dMn), 3.2 × 102 (n = 430) for EF(dCo), and 1.2 × 103 (n = 413) for EF(dPb). The EF(dPb) found in this study is on the same order of magnitude as the EF values for aerosols found in the literature, suggesting that the deposition of aerosols is a major source for dPb. Because EF(dMn) and EF(dCo) are ten to hundred times higher than the EF for aerosols, sources other than the aerosol deposition are more significant contributors to the concentrations of Mn and Co.

    The distribution of Al, Mn, Fe, Co, Ni, Cu, Zn, Cd, and Pb in seawater was investigated on the Bering Sea shelf (56-64 degrees N, 165-169 degrees W) in September 2000. The unfiltered and filtered seawater samples were used for determination of total dissolvable (TD) and dissolved (D) metals (M), respectively. The TD-M concentrations were generally higher than in the Pacific Ocean. TD-Cd was highest in deep water of the outer shelf domain and dominated by dissolved species. The other TD-M were highest at stations close to the Yukon River delta and had higher fractions of labile particulate (LP) species that were obtained as the difference between TD-M and D-M. Dissolved Al, Ni, and Cu were characterized by input from the Yukon River. Dissolved Mn and Co showed maximums on the bottom of the coastal domain, suggesting influence of sedimentary Mn reduction. The correlations of D-Zn, D-Cd, and macronutrients indicated their distributions were largely controlled through uptake by microorganisms and remineralization from settling particles. All these three processes (river input, sedimentary reduction, and biogeochemical cycle) had an influence on the distribution of D-Fe. D-Pb was fairly uniformly distributed in the study area. The stoichiometry of D-M in the Bering Sea shelf showed enrichment of Co and Pb and depletion of Ni, Cu, Zn, and Cd compared with that in the North Pacific. The LP-M/LP-Al ratio revealed significant enrichment of the other eight metals relative to their crustal abundance, suggesting importance of formation of Fe-Mn oxides and adsorption of trace metals on the oxides.

    Understanding the circulation of water masses in the world's oceans is critical to our knowledge of the Earth's climate system. Trace elements and their isotopes have been explored as tracers for the movement of water masses(1). One type of candidate elements(2) are the high-field-strength elements zirconium (Zr), hafnium (Hf), niobium (Nb) and tantalum (Ta). Here we measure the distributions of dissolved Zr, Hf, Nb and Ta along two meridional sections in the Pacific Ocean that extend from 65 degrees to 10 degrees S and from 10 degrees to 50 degrees N. We find that all four elements tend to be depleted in surface water. In the deep oceans, their concentrations rise along our transects from the Southern Ocean to the North Pacific Ocean, and show strong correlations with the concentration of silicate. These results indicate that terrigenous sources are important to the budget of Zr, Hf, Nb and Ta in sea water, compared with hydrothermal input. Unexpectedly, the weight ratios for Zr/Hf fall between 45 and 350 and those for Nb/Ta between 14 and 85 in Pacific sea water, higher than the ratios observed in fresh water, in the silicate Earth or in chondritic meteorites. We conclude that the fractionation of Zr/Hf and Nb/Ta ratios will be useful for tracing water masses in the ocean.

    Bioactive trace metals are essential or highly toxic elements for organisms. The most important bioactive trace elements in the ocean environment are Al, Mn, Fe, Co, Ni, Cu, Zn, Cd and Pb, whose concentrations in seawater are generally less than tens of nmol kg<sup>−1</sup>. In previous methods, there were problems, such as contamination, interferences by major constituents and a non-quantitative recovery of the target metals, especially Al and Mn. We developed a novel method for analyzing the 9 elements based on solid-phase extraction-inductively coupled plasma mass spectrometry (ICP-MS). In this method, a column packed with chelating absorbent, which had ethylenediaminetriacetic and iminodiacetic acid groups, was used in a closed concentration system. The proposed method was able to concentrate all of the 9 elements simultaneously and quantitatively, and to remove the major constituents in seawater. The procedural blanks for Mn, Co, Ni, Cu and Cd were less than the detection limits for ICP-MS (3 times the standard deviations of 1 mol L<sup>−1</sup> HNO<sub>3</sub>), and those for Al, Fe, Zn and Pb were 0.14, 0.03, 0.07 and 0.003 nmol kg<sup>−1</sup>, respectively. The overall detection limits for Al, Mn, Fe, Co, Ni, Cu, Zn, Cd and Pb were 0.24, 0.01, 0.04, 0.002, 0.01, 0.01, 0.06, 0.01 and 0.001 nmol kg<sup>−1</sup>, respectively. In this paper, we review the development of this method and its application to international intercalibration using open-ocean seawater.

    It is widely recognized that the natural isotopic variation of Mo can provide crucial information about the geochemical circulation of Mo, and the ocean is an important reservoir of Mo. To obtain precise isotopic data on Mo in seawater samples using multiple collector-inductively coupled plasma mass spectrometiy (MC-ICPMS), we have developed a preconcentration technique using 8-hydroxyquinoline bonded covalently to a vinyl polymer resin (TSK-8HQ). By optimizing the procedure, Mo in seawater could be effectively separated from matrix elements such as alkali, alkaline earth, and transition metals. With this technique, even with a 50-fold enrichment factor, the changes in the (98)Mo/(95)Mo ratio during preconcentration were smaller than twice the standard deviation (SD) in this study. Mass discrimination of Mo isotopes during the measurement was externally corrected for by normalizing (86)Sr/(88)Sr to 0.1194 using an exponential law. We evaluated delta(98)/(95)Mo to a precision of +/- 0.08 parts per thousand (+/- 2 SD); this value was found to be less than one-third of previous reported values. Moreover, we were able to determine an accurate ratio for every pair of stable Mo isotopes, which was impossible with previous methods owing to the isobaric interference from the external elements (Zr and Ru). In this study, delta(92)/(98)Mo in seawater was first determined so that it had the smallest relative error. We applied the proposed method to four kinds of seawater samples. The Mo compositions were constant among them, with average delta(98)/(95)Mo and delta(92)/(98)Mo values of 2.45 +/- 0.11 and -4.94 +/- 0.09 parts per thousand ( +/- 2 SD), respectively. Our data indicate that seawater is enriched in heavy Mo isotopes than previously reported.

    The distribution of dissolved (D) and acid-dissolvable (AD) Fe, Ni, Cu and Pb in the upper water column (0-300 m depth) was determined in the Australian sector of the Southern Ocean (140 degrees E meridian) during three cruises conducted between November 2001 and March 2002. For Ni and Cu, there was no significant difference in concentration between dissolved and acid-dissolvable species. DNi and DCu showed significant (P = 0.01) positive correlations with silicate, phosphate and nitrate, reflecting their strong nutrient-type behaviour. For Fe and Pb. the acid-dissolvable concentration mostly exceeded the dissolved concentration, reflecting the importance of labile particulate species for these elements. DPb decreased between January and February in the Polar Frontal Zone and in Antarctic continental shelf water. ADPb maxima occurred in the Antarctic Zone, resulting in a maximum AD/D ratio of 7. The mean DFe concentration in the surface mixed layer was 0.3 nM in the sub-Antarctic zone, 0.4 nM in the Polar Frontal Zone, 0.5 nM in the Antarctic Zone and increased southward beyond the Antarctic Divergence and towards the continent. DFe did not show a clear temporal change in its horizontal distribution, which was in contrast to the other nutrients and trace metals. ADFe substantially increased in Antarctic continental shelf water where the AD/D ratio reached 11. The following conclusions can be drawn from these data. (I) Ni and Cu exist exclusively as dissolved species and their distributions are mainly controlled by their biogeochemical cycling. similar to those of the major nutrients. (2) Pb is dominated by particulate species. The distribution of DPb is temporally and spatially variable due to a sporadic source and strong scavenging. (3) DFe is rather a minor fraction of total Fe in Antarctic continental shelf water where shelf sediments and Antarctic sea-ice appear to be strong sources for Fe. There is substantial temporal variation in the supply of Fe to the upper water column. DFe in the mixed layer of the open Southern Ocean is maintained at low concentrations throughout summer due to uptake by phytoplankton and scavenging. (c) 2008 Elsevier B.V. All rights reserved.

    GEOTRACES is an international research project on marine biogeochemical cycles of trace elements and their isotopes. GEOTRACES key trace metals in seawater are A1 (8-1000 ng/kg), Mn (4-300 ng/kg), Fe (1-100 ng/kg), Cu (30-300 ng/kg), Zn (3-600 ng/kg), and Cd (0.1-100 ng/kg), of which global oceanic distribution will be determined on a number of research cruises. This work introduces a novel method of solid-phase extraction to determine Al, Mn, Fe, Co, Ni, Cu, Zn, Cd, and Pb in seawater by adjusting the pH of the sample to 6 and carrying out a single preconcentration step. The trace metals were collected from similar to 120 mL of seawater using a column of a chelating resin containing the ethylenediaminetriacetic acid functional group and eluted with similar to 15 mL of 1 M HNO(3). Mn and Fe in the eluate were measured by inductively coupled plasma mass spectrometry (ICPMS) using the dynamic reaction cell mode, and the other metals were measured using the standard mode. Using this procedure, the trace metals were collected quantitatively, while &gt; 99.9% of alkali and alkaline earth metals in seawater were removed. The procedural blank was &lt;7% of the mean concentration in deep ocean waters, except 16% for Pb. The overall detection limit was &lt; 14% of the mean concentration in deep ocean waters. The RSD was &lt;9%. Our values for the trace metals in the certified reference materials of seawater NASS-5 and nearshore seawater CASS-4 agreed with the certified values (except that there is no certified value for Al). This method was also successfully applied to the reference materials of open-ocean seawater produced by the SAFe program. Our Fe concentrations were 5.9 +/- 0.7 ng/kg for surface water (S) and 50.4 +/- 2.9 ng/kg for deep water (D2), which are in agreement with the interlaboratory averages of 5.4 +/- 2.4 and 50.8 +/- 9.5 ng/L, respectively. The data for other metals were oceanographically consistent.

    Dissolved and labile particulate Zr, Hf, Nb, Ta, Mo and W were determined at stations K1 (51 degrees N, 165 degrees E), K2 (47 degrees N, 160 degrees E), KNOT (44 degrees N, 155 degrees E) and 35N (35 degrees N, 160 degrees E) in the western North Pacific Ocean. A portion of seawater for dissolved species (D) was passed through a 0.2 mu m Nuclepore filter and acidified to pH 2.2 with HCI and HE A portion of seawater for acid-dissolvable species (AD) was acidified without filtration. Labile particulate (LP) species is defined as AD minus D, which represents a chemically labile fraction of particulate species. D-Zr, Hf and Ta increase with depth, Nb shows a slight depletion in surface water, whereas Mo and W have a conservative vertical profile. The concentration range of D-Zr, Hf, Nb, Ta and W is 31-275, 0.14-0.95, 4.0-7.2, 0.08-0.29 and 40-51 pmol kg(-1), respectively, whereas that of Mo is 97-105 nmol kg(-1). LP-species of Zr, Hf and Ta account for 10-14% of AD in average and increase up to 25% below 4000 m, whereas those for Mo and W are negligible. In contrast, LP-Nb shows maxima (up to 27%) in surface water, We also found that D-Zr/Hf, Nb/Ta and Mo/W mole ratios generally increase in the order continental crust &lt; river water &lt; coastal sea &lt; open ocean.

    Solid phase extraction with chelating adsorbents is useful for the preconcentration of trace metals in seawater. We have examined a number of chelating adsorbents and developed simultaneous determination methods for trace metals in seawater on the basis of preconcentration by solid phase extraction and determination by ICP-MS. Here we review the results on the determination of trace bioactive metals(Fe, Co, Ni, Cu, Zn, Cd and Pb)using fluoride-containing metal alkoxide glass immobilized 8-hydroxyquinoline(MAF-8HQ)and the determination of the second and third transition series metals(Zr, Hf, Nb, Ta, Mo and W)using vinyl polymer resin immobilized 8-hydroxyquinoline(TSK-8HQ).

    A new technique for the determination of suspended particulate trace metals (P-metals &gt; 0.2 mu m), such as Co, Ni, Cu, Zn, Cd and Pb, in open ocean seawater has been developed by using microwave digestion coupled with flow injection inductively coupled plasma mass spectrometry (FI-ICP-MS). Suspended particulate matter (SPM) was collected from 500 mL of seawater on a Nuclepore filter (0.2 mu m) using a closed filtration system. Both the SPM and filter were completely dissolved by microwave digestion. Reagents for the digestion were evaporated using a clean evaporation system, and the metals were redissolved in 0.8 M HNO3. The solution was diluted with buffer solution to give pH 5.0 and the metals were determined by FI-ICP-MS using a chelating adsorbent of 8-hydroxyquinoline immobilized on fluorinated metal alkoxide glass (MAF-8HQ). The procedure blanks with a filter were found to be 0.048 +/- 0.008, 10.3 +/- 0.3, 0.27 +/- 0.05, 3.3 +/- 1.8, 0.02 +/- 0.03 and 0.85 +/- 0.09 ng L-1 for Co, Ni, Cu, Zn, Cd and Pb, respectively (n = 14). Detection limits defined as 3 times the standard deviation of the blanks were 0.023, 0.90, 0.14, 5.3, 0.078 and 0.28 ng L-1 for Co, Ni, Cu, Zn, Cd and Pb, respectively. Accuracy was evaluated using certified reference materials of chlorella (NES CRM No. 3) and marine sediment (HISS-1). The method was applied to the determination of vertical distributions for P-Co, Ni, Cu, Zn, Cd and Pb in the Western North Pacific. (c) 2007 Elsevier B.V. All rights reserved.

    Here, we present the first simultaneous preconcentration and determination of ultratrace (pmol kg(-1) level) Zr, Hf, Nb, Ta and W in seawater, both in the form of dissolved and acid-dissolvable species. 8-Hydroxyquinoline (8HQ) bonded covalently to a vinyl polymer resin, TSK-8HQ, was used in a chelating adsorbent column to concentrate the metals. The greatest advantage of this resin is its endurance to 5 M HF, since this is an effective eluent for all five metals. The analytes were successfully concentrated from 250 mL seawater with a 50-fold concentration factor through the column extraction and evaporation. The detection limit was 0.009-0.15 pmol kg(-1). The procedure blank determined using ultra pure water as a sample was 0.005-0.37 pmol kg(-1). The five metals were quantitatively recovered from seawater with good precision (2-4%). The effect of sample pH, sample flow rate, eluent composition and sample pretreatment were carefully studied. This method was applied to seawater. (c) 2006 Elsevier B.V. All rights reserved.

    Here we present the first vertical distribution of dissolved (D) and acid-dissolvable (AD) bioactive trace metals (Fe, Co, Ni, Cu, Zn and Cd) in the Sulu Sea and the South China Sea, together with those observed previously by the same method in the western North Pacific. At a depth of 50-75 m, concentration minima of some trace metals were observed in the Sulu Sea (D-Zn, Cu and Fe) and the South China Sea (D-Zn), which coincided with the Chl a maximum, indicating scavenging of these metals including biological uptake. Above 150 m in the South China Sea, elevated concentrations of D-Co and Cu were observed, which could result from fluvial/coastal waters and/or shelf-sedimentary sources. In the surface mixed layer in the Sulu Sea, D-Fe concentrations were high (2 nM), presumably due to the flowing of waters across the Philippine Archipelago.
    Except for Fe, concentrations of D and AD species at each corresponding depth were not significantly different. Concentrations of AD-Fe (6.8-17 nM), below 500 m in the Sulu Sea were much higher than those of D-Fe (0.2-1.7 nM), indicating that particulate Fe is abundant in the basin, probably coming from nearby sedimentary sources.
    The vertical distributions of D-Ni, Cu, Zn and Cd in the South China Sea were nutrient-like and deviated slightly from those in the western North Pacific. This is caused by a rapid flushing of waters from the Philippine Sea coupled with vertical mixing within the South China Sea. The distribution of these metals in the Sulu Sea was more uniform below 500 m. The average concentrations of D-Ni, Cu, Zn and Cd in the deep water of the Sulu Sea were 6.1, 1.5, 3.3 and 0.5 nM, significantly lower than those of the western North Pacific (9.6, 2.8, 10.1 and 1.0 nM, respectively). We also found lower D-Cd/PO4, Ni/PO4 and Zn/Si(OH)(4) ratios in the Sulu Sea than those of the Pacific. The depletion of these concentrations and the D-Cd/PO4 and Ni/PO4 ratios in the Sulu Sea is probably because the deep water of the basin is rapidly exchanged with shallow waters but isolated from nutrient-rich deep waters derived from the North Pacific, due to the surrounding topographic barriers including the islands and the shallow sills ( &lt; 420 m). The lower D-Zn/Si(OH)(4) ratios in the Sulu Sea are probably due to the relatively low D-Zn/Si(OH)(4) ratios in the upper water coupled with the preferential supply of Si(OH)(4) relative to Zn at depth.
    While subsurface waters were flowing along density surfaces (sigma- T values of similar to 26) from the South China Sea to the Sulu Sea, the concentrations of macronutrients, D-Ni, Cu, Zn and Cd increased due to the regeneration from biogenic particles. The increases in the concentrations of bioactive elements relative to that Of PO4 were N: P: Si: Ni: Cu: Zn: Cd = 15: 1: 40: 2.4 x 10(-3) :0.6 x 10(-3) : 2.7 x 10(-3) : 0.03 x 10(-3) in a molar unit.

    The sample, preparation and analytical methodology are described for determining minor and trace elements (Al, As, Ba, Cd, Co, Cr, Fe, Mg, Mn, Mo, Ni, Sb, Sr, U, V, W, Y and Zn) in biogenic carbonate minerals of coccolithophores. Coccolith particles isolated from cultivated coccolithophores were purified by centrifugation and resuspension with 0.5 mM sodium hydrogencarbonate solutions (1 M = 1 mol L-1). The concentrations of the elements in the final solutions were determined by high-resolution inductively coupled plasma mass spectrometry and inductively coupled plasma atomic emission spectrometry. The analytical results of coccolith particles suggest that the molar ratios of the minor and trace elements in coccoliths vary with the compositions of the medium in which the coccolithophores are grown.

    Arsenic transformations by freshwater algae have been studied under laboratory conditions. By the use of a new analytical method, we identified methylarsenic(III) species in the growth medium of green-alga Closterium aciculare incubated under axenic conditions. The arsenate concentration in the experimental medium began to decrease just after inoculation, and the levels of arsenite and methylarsenicals increased with the growth of C. aciculare. Initially, most of the arsenate was converted into arsenite, which peaked in concentration during the exponential phase. Methylarsenicals accumulated rapidly in the stationary phase. DMAA(V) production was enhanced when the ratio of phosphate to arsenate decreased in the culture medium. The levels of DMAA(V) increased continuously toward the end of the experiment. On the other hand, methylarsenic(III) species remained relatively steady during the stationary phase. Methylarsenic(III) species accounted for 0-35% of methylarsenicals. These results suggest that arsenite and methylarsenicals (containing methylarsenic(III) species) are supplied by phytoplankton, and serve as evidence of the origin of methylarsenic(III) species in natural waters.

    A method for preconcentrating Zr from large volumes of seawater using MnO2-impregnated fibers is described. The manganese dioxide-impregnated fibers were synthesized from polypropylene cartridge filters by a redox reaction between KMnO4 and MnCl2. Seawater samples were introduced into an extraction system and Zr was extracted from the samples by the MnO2-impregnated fibers. Zirconium was recovered from the fibers through two steps of elution into aqueous solutions and measured by inductively coupled argon plasma atomic emission spectrometry. The average extraction efficiency for Zr was 59% on a single pass of 50-1000 l sample at flow rates of 8.1-15 l min(-1), and 100% on continuous circulation of 200 l sample at 15 l min(-1). The results indicate that Zr can be rapidly and easily preconcentrated onto MnO2-impregnated fibers from large volumes of seawater. This simple method can be applied to the preconcentration of trace dissolved Zr in natural water and removal of radiozirconium from radioactive waste fluid. (C) 2000 Elsevier Science B.V.
