“…Table 5 presents a comparison between the proposed optode and the other reported techniques recommended in the literature 19,20,22,27,60–69 for the determination of selenium. It is clear that the suggested approach has many benefits, including simplicity, low cost, rapidity, minimal toxicity, and relatively high selectivity.…”

“…Se has a very important role for the synthesis of 25 selenoproteins, including glutathione peroxidase, thioredoxin reductase and iodothyronine deiodinases [35]. It is vital in the functioning of the structural and enzymatic system in the body, including its positive effect on the immune system, anti-carcinogenic effect, balancing redox reactions [36]. Higher and lower Se levels compared to the required amounts for living organisms have some health risks, and the required amount of Se in humans has a narrow window [37].…”

Mushrooms are a popular food because they are an important source of essential amino acids, proteins and dietary fibers, but they have a great capacity to accumulate metals from substrate. Due to this reason, the content of 5 trace metals (Fe, Cr, Zn, Pb, Se) of fruit bodies of 21 fungi species originally found in Azdavay, Kastamonu Region, Turkey were analyzed by atomic absorption spectroscopy. The contents of investigated trace metals in mushroom samples were found to be in the range of 4.6–3478.7 mg kg-1 for Fe, 5.1–19.9 mg kg-1 for Cr, 10.4–138.6 mg kg-1 for Zn, 5.8–28.0 mg kg-1 for Pb and 0.65–1.47 mg kg-1 for Se.The relative standard deviations (R.S.D.) were found below 10%. The accuracy of procedure was confirmed by CRMs (BCR 191 Brown bread, ERM-BD 151 Skimmed milk powder)

A novel ultra‐sensitive gold‐coated tungsten‐coil atom trap coupled with HGAAS was developed for the first time for the determination of arsenic. The analytical methodology was based on transporting and in‐situ trapping of arsine produced by the hydride generation system onto a gold‐coated W‐coil trap for preconcentration via Ar and H2 gases. The trap surface was examined using scanning electron microscopy and energy‐dispersive X‐ray spectroscopy. SEM images revealed that the surface is covered with hexagonal and pentagonal structures on a micro scale with gold. The experimental parameters were optimized for both trap and non‐trap method. The enhancement factor for the characteristic concentration (C0) was determined to be 15.3 when compared with the non‐trap methods. For the trapping time of 120 s using the developed method, the limit of detection (LOD) and the precision were determined as 4.8 ng L−1 and 3.6 %, respectively. The interference effects of various hydride‐forming ions were examined in detail. The accuracy of this ultrasensitive methodology was successfully verified by analysis of certified reference materials and some drinking water samples.. t‐test was implemented to the water samples, the added and measured concentrations exhibited no statistically meaningful distinction at the 95 % confidence level.
