“…The internal reference method may be employed if an element similar to the internal standard is not included in the sample. Although ICP-MS is a highly sensitive method, the intensity depends on the mass number due to spacecharge e#ects 14) . Therefore, in this study, Ge was used as the internal reference element in the determination of total As, because its mass number is close to that of As.…”

The determination method of total arsenic (As) and the speciation method of inorganic As for non-glutinous rice reported in our preceding paper were applied to several varieties of rice under optimized experimental conditions. In the determination of total As with ICP-MS, acetic acid was added to increase the sensitivity and an internal reference method with germanium was adopted to increase the precision. The extraction temperature in the partial-digestion method with nitric acid to speciate inorganic As was raised to 100ῌ, because extraction e$ciency over 90῍ was obtained from glutinous rice and colored rice at this temperature. In the investigation of polished and unpolished forms of non-glutinous, glutinous, and colored rice, the amounts of total and inorganic As were 0.04ῌ0.54 mg/kg and 0.02ῌ0.41 mg/kg, respectively. The color of rice was not related to total or inorganic As content. These results indicate that the inorganic As content in commercial rice should be carefully monitored.

19Pre-salt reservoir systems encountered offshore Brazil and Angola that consist of porous continental 20 carbonates are difficult to access because of the limited core material that is under concession. 21 Therefore, it is important to study comparable continental carbonate analogues, like travertines and 22 lacustrine carbonates, that possess similar porosity and permeability characteristics. The Budakalász 23Pleistocene travertines (Buda Hills, Hungary) have been studied from a sedimentological, geochemical 24 and reservoir point of view in order to understand their formation, petrophysical properties and 3D 25 reservoir architecture. 26The three-dimensional geobody architecture of the Budakalász travertines illustrates the potential 27 complexity of kilometre scale continental carbonate systems. Heterogeneous smooth sloping travertine 28 lobes consisting of terrace slope, smooth slope and reed facies, are covered by a lime mudstone 29 dominated, gastropod-and charophyte-rich marsh-pool facies. The observed facies represent a change 30 from a subaerial travertine to a palustrine to lacustrine system, reflecting the ceasing of the system due 31 to tectonic uplift. The dominant paleo-flow direction of the sloping lobes was towards the Danube 32 depression, with several subordinate flow systems identified. 33The Sr-C-O isotope geochemical signatures reflect travertine precipitation at ambient to superambient 34 temperatures from meteoric derived fluids with a mixed CO2 origin of the marine carbonate fluid 35 source rocks and an atmospheric or soil-derived component. Although the uniform signatures of the 36 stable oxygen and carbon isotopes, in addition to petrographic observations suggest partial diagenetic 37 isotopic resetting, the primary geospatial isotope trends seem to have been preserved. 38 2 A reservoir-oriented facies evaluation in the three-dimensional geobody frame of the Budakalász 39 carbonates based on porosity and permeability core plug analyses reveals their heterogeneous nature. 40Terrace, smooth slope and marsh-pool facies have considerable porosities of 5-15%, while the 41 porosity of the reed facies may reach up to 27%. Permeability of all facies is strongly anisotropic, 42 mainly controlled by a better connectivity along layer-parallel primary pores. 43The reconstruction of the 3D geobody architecture of the Budakalász lobe complex coupled to its 44 geochemical and petrophysical properties provides a unique dataset that so far was lacking. 45 46

AbstractThis work explores the multi-element capabilities of inductively coupled plasma -mass spectrometry with collision/reaction cell technology (CCT-ICP-MS) for the simultaneous determination of both spectrally interfered and non-interfered nuclides in wine samples using a single set of experimental conditions. The influence of the cell gas type (i.e. He, He + H 2 and He + NH 3 ), cell gas flow rate and sample pre-treatment (i.e. water dilution or acid digestion) on the background-equivalent concentration (BEC) of several nuclides covering the mass range from 7 to 238 u has been studied. Results obtained in this work show that, operating the collision/reaction cell with a compromise cell gas flow rate (i.e. 4 mL min -1 ) improves BEC values for interfered nuclides without a significant effect on the BECs for non-interfered nuclides, with the exception of the light elements Li and Be. Among the different cell gas mixtures tested, the use of He or He + H 2 is preferred over He + NH 3 because NH 3 generates new spectral interferences.2 No significant influence of the sample pre-treatment methodology (i.e. dilution or digestion) on the multi-element capabilities of CCT-ICP-MS in the context of simultaneous analysis of interfered and non-interfered nuclides was observed.Nonetheless, sample dilution should be kept at minimum to ensure that light nuclides (e.g. Li and Be) could be quantified in wine. Finally, a direct 5-fold aqueous dilution is recommended for the simultaneous trace and ultra-trace determination of spectrally interfered and non-interfered elements in wine by means of CCT-ICP-MS. The use of the CCT is mandatory for interference-free ultra-trace determination of Ti and Cr. Only Be could not be determined when using the CCT due to a deteriorated limit of detection when compared to conventional ICP-MS.
