“…With respect to lead, Pitts and Wallace (1994) established a correlation between the concentration of Pb in seawater and the concentration of Pb in a bivalve shell. Assuming the concentration of Pb in seawater in offshore seawater to be 50 ng/kg (Reimer and Miyazaki, 1992), we obtain a concentration of ≈ 0.5 ppm Pb in shell calcite. The dissolution of calcite caused by the increase in P(CO 2 ) from 10 -2 to 10 bar would result in an increase in Pb concentration by ≈ 10 -10 mol/kg H 2 O, which is trivial.…”

On mobilization of lead and arsenic in groundwater in response to CO2 leakage from deep geological storage

If carbon dioxide stored in deep saline aquifers were to leak into an overlying aquifer containing potable groundwater, the intruding CO 2 would change the geochemical conditions and cause secondary effects mainly induced by changes in pH In particular, hazardous trace elements such as lead and arsenic, which are present in the aquifer host rock, could be mobilized. In an effort to evaluate the potential risks to potable water quality, reactive transport simulations were conducted to evaluate to what extent and mechanisms through which lead and arsenic might be mobilized by intrusion of CO 2 . An earlier geochemical evaluation of more than 38,000 groundwater quality analyses from aquifers throughout the United States and an associated literature review provided the basis for setting up a reactive transport model and examining its sensitivity to model variation. The evaluation included identification of potential mineral hosts containing hazardous trace elements, characterization of the modal bulk mineralogy for an arenaceous aquifer, and augmentation of the required thermodynamic data. The reactive transport simulations suggest that CO 2 ingress into a shallow aquifer can mobilize significant lead and arsenic, contaminating the groundwater near the location of intrusion and further downstream. Although substantial increases in aqueous concentrations are 2 predicted compared to the background values, the maximum permitted concentration for arsenic in drinking water was exceeded in only a few cases, whereas that for lead was never exceeded.

A solid phase extraction method for the determination of gold(III) at trace levels by flame atomic absorption spectrometer (FAAS) was developed. The method was based on retention of gold as chloro complexes through the Amberlite XAD-2000. The effect of some analytical parameters including hydrochloric acid concentration, sample volume, sample and eluent flow rates, eluent volume, eluent concentration and interfering ions on the recovery of gold(III) was investigated. The retention of gold(III) from 1.5 mol l(-1) HCl solution and the recovery of gold with 0.07 mol l(-1) NH3 solution were quantitative (>or=95%). The relative standard deviation (RSD) was calculated as 3.2% (n = 10). The detection limit for gold was 2 microg l(-1). The accuracy was checked with the determination of gold spiked an artificial seawater and a pure copper samples.

“…This drawback was overcome by combination of a suitable preconcentration technique with subsequent determination by ICP-AES. Preconcentration method was used for water samples such as solvent extraction, co-precipitation, resin chelation and various chromatographic techniques (Horvath et al, 1991;Lo et al, 1991;Xu and Schramel, 1992;Zhang et al, 1997;Reimer and Miyazaki, 1992;Pai, 1998;Prusisz and Zyrnicki, 1998;Cesur, 2003;Sarocoglu et al, 2003;Ramadevi, 1989;Balaji, 1993;McCarthy et al, 1991).…”

A procedure was developed for the determination of Cd, Cu, Zn, Co, Ni, Mn, Pb and Mo in water samples by inductively coupled plasma atomic emission spectrometry (ICP-AES) after preconcentration on a morpholine dithiocarbamate (mor-DTC) supported by bagasse (Saccharam aphisinaram). The sorbed elements were subsequently eluted with 4,M HNO3 and the acid eluates were analysed by ICP-AES. The influence of various parameters such as pH, flow rate of sample, eluent concentration, volume of the sample and volume of eluent were investigated to enhance the sensitivity of the present method. A 20,mL disposable syringe served as preconcentration column. Under the optimal conditions Cd, Cu, Zn, Co, Ni, Mn, Pb and Mo in aqueous sample was concentrated about 100-fold. The sorption recoveries of elements were higher than 99.6%. The method is also applied for the analysis of natural and spiked water samples.
