Abstract The study involves the analysis of total arsenic (As) in metallic form, and organic and inorganic As species from seaweeds and dietary supplements. The analysis provides data for dietary exposure estimatesof inorganic species that are considered more toxic to humans than organic and total As. Total As was determined by acid digestion followed by inductively coupled plasma (ICP)-MS. To characterize the As species, solvent extraction with sonication and microwaveextraction using various aqueous and aqueous/organicsolvent mixtures were initially evaluated. The optimum As speciation method was determined to be water extraction followed by anion exchange HPLC coupled with ICP-MS. Optimization of chromatographic conditions led to baseline separation for six As species, including As acid, arsenous acid, monomethylarsonic acid, dimethylarsinic acid, arsenobetaine, and arsenocholine, in approximately 8 min using gradient elution. Detection limits for all six compounds were in therange of 10–15 ng/mL. The data presented herewill be valuable for the QA of analytical method development and surveys of total As and As species indietary supplements. The most abundant As species found were arsenite [As(III)] and arsenate [As(V)]. The sum of inorganic As species present in the dietary supplements ranged from 1.2 to 31 μg/day. In addition, the dietary supplements purported to contain fucoxanthin, a carotenoid having pharmacological activities, were analyzed using ultra-performance LC-UV/MS.

AbstractProgress improving zinc nutrition globally is slowed by limited understanding of population zinc status. This challenge is compounded when small differences in measurement can bias the determination of zinc deficiency rates. Our objective was to evaluate zinc analytical accuracy and precision among different instrument types and sample matrices using a standardized method. Participating laboratories analyzed zinc content of plasma, serum, liver samples, and controls, using a standardized method based on current practice. Instrument calibration and drift were evaluated using a zinc standard. Accuracy was evaluated by percent error vs. reference, and precision by coefficient of variation (CV). Seven laboratories in 4 countries running 9 instruments completed the exercise: 4 atomic absorbance spectrometers (AAS), 1 inductively coupled plasma optical emission spectrometer (ICP-OES), and 4 ICP mass spectrometers (ICP-MS). Calibration differed between individual instruments up to 18.9% (p < 0.001). Geometric mean (95% CI) percent error was 3.5% (2.3%, 5.2%) and CV was 2.1% (1.7%, 2.5%) overall. There were no significant differences in percent error or CV among instrument types (p = 0.91, p = 0.15, respectively). Among sample matrices, serum and plasma zinc measures had the highest CV: 4.8% (3.0%, 7.7%) and 3.9% (2.9%, 5.4%), respectively (p < 0.05). When using standardized materials and methods, similar zinc concentration values, accuracy, and precision were achieved using AAS, ICP-OES, or ICP-MS. However, method development is needed for improvement in serum and plasma zinc measurement precision. Differences in calibration among instruments demonstrate a need for harmonization among laboratories.
