“…Aluminium is mobilized from the soil by reductions of surface water pH and can reach 100 µmol l -1 (total aluminium) during low pH episodes (Reader & Dempsey 1989). However, aluminium concentration in seawater is usually much lower (< 20 nmol l -1 in open oceans but up to 150 nmol l -1 in semi-enclosed seas, Tria et al 2007). In addition, calcium, which counteracts the toxic effects of aluminium, is higher in seawater (10 mmol l None of the aquaculture studies examined mortality during early developmental stages (see initial body weight in Table 2).…”

Research interest in CO 2 -driven ocean acidification has been centered on certain groups of calcifying marine organisms, but knowledge on the possible impacts of ocean acidification on fish is limited. Our survey of the existing literature on the effects of increased pCO 2 on fish (total of 116 papers) revealed that few studies were conducted under pCO 2 conditions relevant to the future scenarios of ocean acidification. Information is nearly absent on reproduction, early development, and behaviour of marine fish. The short experimental durations of these studies preclude forecasting of how mortality and growth of marine fish would be affected by future increases in seawater CO 2 . Fish have been shown to maintain their oxygen consumption under elevated pCO 2 conditions, in contrast to declines seen in several marine invertebrates, in spite of possible additional energetic costs incurred by higher pCO 2 . Impacts of prolonged CO 2 exposure on reproduction, early development, growth, and behaviour of marine fish are important areas that need urgent investigation. There is also a need to rapidly advance research into possible acclimation of marine fish to high pCO 2 environments, endocrine responses to prolonged CO 2 exposure, and indirect influences through food availability and quality on fish growth, survival and reproduction. Useful guidance could be gained from the rich literature on the effects of freshwater acidification.

“…While Dierssen et al (2001) developed a newer, improved synthesis, the process has still proven to be difficult and time-consuming with significant batch-to-batch variation in resin quality. Furthermore, Tria et al (2007) report peak reproducibility problems when using 8-HQ resins synthesized according to the Landing et al (1986) and Dierssen et al (2001) protocols.…”

“…In a review of Al determinations in seawater, Tria et al (2007) note that while the flow-injection analysis (FIA)-fluorescence methods have had reported success, "the technique can still benefit from several refinements, notably in the area of analyte preconcentration." (p.163) The goal of this work was to develop a highly sensitive, shipboard, flow injection analysis system based on the work of Resing and Measures (1994) yet using a commercially available preconcentration resin.…”

An improved, highly sensitive, flow-injection analysis method for the determination of dissolved aluminum in seawater, based on the work of Resing and Measures (1994), is presented. The most significant modification to this earlier work is the use of in-line preconcentration of seawater onto a commercially available resin, eliminating the resin-synthesis step. Other modifications include the addition of a column-conditioning step prior to sample loading that increases the quantitative retention and sensitivity, in-line buffering of samples prior to column loading to achieve optimal sample pH, an increased acid-eluent concentration to efficiently remove Al from the resin column, and an increased reaction buffer concentration. The method has a detection limit of 0.1 nM Al when preconcentrating 10 mL sample and a precision of 2.5% based on replicate analyses of a 5 nM Al sample when preconcentrating 2.5 mL sample. The method was applied to surface and deepwater samples collected in the North Pacific (2004 Sampling and Analysis for Fe [SAFe] cruise) and from surface water samples collected across the Columbia River plume. Results suggest that the SAFe samples could potentially serve as seawater reference materials for dissolved Al following further investigation by other researchers using different methods. The use of low-density polyethylene bottles with low-density polyethylene caps as standard protocol for storage of acidified seawater samples for Al analysis is also discussed.

“…26,27 Even so, the detection of Al(III) has always been problematic because of its pH-dependence in aqueous solution and its poor coordination ability comparing to transition metals. 28,29 Well established procedures for quantitative detection of aluminium have been reviewed by Tria et al, 30 and referenced by Lide. 31 Moreover, recently some novel sensors have been developed.…”

Potential Aluminium(III)- and Gallium(III)-selective Optical Sensors Based on Porphyrazines

et al. 2011

Porphyrazines possessing non-coordinating alkyl (propyl) and aralkyl (4-tert-butylphenyl) groups in the periphery were studied as optical sensors for a set of mono-, di-and trivalent cations. Investigated porphyrazines in the UV-Vis monitored titrations revealed significant responses towards aluminium and gallium cations, unlike other metal ions studied. Additionally, porphyrazine possessing 4-tert-butylphenyl peripheral substituents showed sensor property towards ruthenium cation and was chosen for further investigation. The presence of isosbestic points in absorption spectra for its titration with aluminium, gallium and ruthenium cations, accompanied by a linear Benesi-Hildebrand plot, proved complex formation. The continuous variation method was used to determine binding stoichiometry in 1:1 porphyrazine-metal ratio. X-Ray studies and density functional theory calculations were employed to investigate octa(4-tert-butylphenyl)-porphyrazine structure. The results helped to explain the observed selectivity towards certain ions. Interaction between ion and porphyrazine meso nitrogen in a Lewis acid-Lewis base manner is proposed.
