In this study, the effectiveness of three choline chloride (ChCl)-based deep eutectic solvents (DESs) formed using malonic acid (MalA), glycerol (Gly), and glucose (Glu) as hydrogen bond donors two conventional (50% methanol 50% ethanol) for ultrasonic-assisted extraction (UAE) antioxidant compounds from four herbs (chamomile, lemon balm, nettle, spearmint) were estimated. The capacity (AC) obtained herb extracts was determined by modified 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic...
Abstract Mineral dust is the major source of external micro-nutrients such as iron (Fe) to open ocean. However, large uncertainties in model estimates Fe emissions and aerosol-bearing solubility (i.e., ratio labile (L ) total (T )) Southern Hemisphere (SH) hampered accurate atmospheric delivery bioavailable Ocean. This study applied an inverse modeling technique a global aerosol chemistry transport (IMPACT) order optimize predictions mineral concentrations based on recent observational data...
Main text Twenty National Metrology Institutes and Designated registered in the CCQM Key Comparison of CCQM-K155 "Elements Tributyltin Seawater" nineteen institutes submitted their results. Participants were requested to evaluate mass fractions, expressed ng/g, arsenic, cadmium, copper, lead, nickel, zinc ng/kg level tributyltin seawater. Reference Values (KCRVs) are assigned various measurands by NIST decision tree approach (NDT). used analytical methods choice. Most participants employed...
The feasibility of the use NOVA-2 dual-flow ultrasonic nebulizer for determination selenium, antimony and arsenic in drinking mineral waters by direct hydride generation inductively coupled plasma-optical emission spectrometry (HG-ICP-OES) has been investigated. acidic sample borohydride solution are mixed directly on surface a quartz oscillating plate converting liquids into aerosol at entrance spray chamber. analytical figures merit multielement were evaluated. Results showed that...
Main text Seafood is one of the major food resources for human consumption in world. The CODEX Alimentarius Commission and many jurisdictions have set maximum levels metallic contaminants seafood. use reliable methods measurement important safeguarding quality these products public health. Supplementary Comparison APMP.QM-S19: Toxic Elements was coordinated by Government Laboratory, Hong Kong, China (GLHK). Four measurands (arsenic, cadmium, mercury lead) seafood were chosen. last CCQM or...
Aerosols deposited into the Great Barrier Reef (GBR) contain iron (Fe) and other trace metals, which may act as micronutrients or toxins to this sensitive marine ecosystem. In paper, we quantified atmospheric deposition of Fe investigated aerosol sources in Mission Beach (Queensland) next GBR. Leaching experiments were applied distinguish pools with regard its solubility. The labile concentration aerosols was 2.3–10.6 ng m−3, is equivalent 4.9%–11.4% total linked combustion biomass burning...
A new 2.45 GHz frequency powered helium plasma source with rotating microwave field generated within the three electrodes has been developed. stable symmetrical low-flow discharge is formed at atmospheric pressure a minimum strength axis. Thus, triangle shaped ring obtained channel center through which sample introduced using laminar dual-flow injector. The operates input power of 30–150 W and total gas flow 200–1500 ml min−1 it self-igniting. preliminary investigation fundamental parameters...
Aerosols from Western Australia supply micronutrient trace elements including Fe into the western shelf of and further afield Southern Indian Oceans. However, regional observations atmospheric metal deposition are limited. Here, we applied a series leaching experiments followed by total analysis bulk aerosol samples to unique time-series collected in determine concentrations solubilities V, Mn, Co, Zn, Pb. Positive matrix factorisation indicated that mineral dust, biomass burning...
Main text The SIM Supplementary Comparison SIM.QM-S12 for Trace Elements in Natural Water was undertaken to assess and demonstrate the analytical capabilities of national metrology institutes (NMIs) designated (DIs) members (or other regions) accurate determination trace elements natural water at µg/kg levels. Evidence successful participation formal, relevant international comparisons is needed document calibration measurement capability claims (CMCs) made by NMIs DIs. Seventeen DIs...
Abstract. Australia contributes a significant amount of dust-borne nutrients (including iron) to the Southern Ocean, which can stimulate marine primary productivity. A quantitative assessment variability in dust fluxes from surrounding ocean is therefore important for investigating impact atmospheric deposition on Ocean's carbon cycle. In this study, lithogenic trace metals (aluminium, iron, thorium, and titanium) contained aerosols collected between 2016 2021 kunanyi / Mount Wellington...
Increased atmospheric Fe loading and solubility was attributed to emissions from Heard Island volcano (Kerguelen plateau), emphasizing the need for models consider volcanoes as a source of aeolian remote oceanic regions.
