“…Electrochemical hydride generation (EcHG), , which uses electrons supplied from the cathode as reductant, represents a suitable alternative to conventional CVG. It has been demonstrated that hydrides of several elements, including As, Hg, Bi, Sb, Pb, Ge, Te, Sn, Se, Zn, and Cd, − could be achieved by EcHG. The most significant advantage of EcHG is that it obviates the need for chemical reducing reagents.…”

In this study, a novel high efficiency vapor generation strategy was proposed on the basis of solution anode glow discharge for the determination of Cd and Zn by atomic fluorescence spectrometry. In this approach, a glow discharge microplasma was acted as a gaseous cathode to initiate the plasma electrochemical vapor generation of Cd and Zn. Cadmium/zinc ions could be converted into molecular species efficiently at the plasma-liquid interface from a supporting electrolyte (HCl, pH = 3.2). It was found that the overall efficiency of the plasma electrochemical vapor generation (PEVG) system was much higher than the conventional electrochemical hydride generation (EcHG) and HCl-KBH system. With no requirement for other reducing reagents, this new approach enabled us to detect Cd and Zn with detection limits as low as 0.003 μg L for Cd and 0.3 μg L for Zn. Good repeatability (relative standard deviation (RSD), n = 5) was 2.4% for Cd (0.1 μg L) and 1.7% for Zn (10 μg L) standard. The accuracy of the proposed method was successfully validated through analysis of cadmium in reference material of stream sediment (GBW07311), soil (GBW07401), rice (GBW10045), and zinc in a simulated water sample (GSB 07-1184-2000). Replacing a metal electrode with a plasma offers the advantage of eliminating potential interactions between the species in liquid and the electrode, which solves the issues associated with electrode encountered in conventional EcHG. The ability to initiate electrochemical vapor generation reactions at the plasma-liquid interface opens a new approach for chemical vapor generation based on interactions between plasma gas-phase electrons and solutions.

“…Activities of GPX and SOD and concentration of malondialdehyde (MDA) were measured by the colorimetric method through the specific assay kits (A005, A001, and A003) that were purchased from the Nanjing Jiancheng Bioengineering Institute of China. Concentrations of Sn in feed and the tissues were measured using the hydride generation atomic fluorescence spectrometer (AF-610B; Beijing Rayleigh Analytical Instrument Corp., Beijing, China) as previously described [33]. Concentrations of protein were measured by the bicinchoninic acid assay [30].…”

Tin (Sn) is widely used in daily life and distributed in many tissues and nutrients. Although over-ingestion of Sn can cause health problems, relatively little attention has been given to the toxic effects of Sn in livestock health and productivity. This study was performed to investigate the toxic effects of prolonged high intake of dietary Sn on broilers. 150 one-day-old Avian broilers were randomly divided into five treatment groups, with five replicates of six birds. For 6 weeks, each group was fed a corn-soybean basal diet (BD) or BD + Sn (as SnCl2) at 120, 240, 480, or 720 mg/kg, respectively. Compared with the control, hepatic glutathione peroxidase (GPX) and superoxide dismutase (SOD) activities were significantly decreased when supplemented with Sn up to 480 mg/kg, while malondialdehyde (MDA) was increased until Sn supplementation at 720 mg/kg. Moreover, dietary Sn supplementation at 720 mg/kg decreased BW gain, feed intake, and impaired feed conversion ratio. The 720 mg Sn/kg group also increased activities of alkaline phosphatase (AKP), while decreased hemoglobin (HGB), red blood cell (RBC), and hematocrit (HCT) in the blood. Furthermore, the accumulation of Sn in various tissues was dose dependent on Sn ingestion. It was found that the tibia and feather are the two main tissues for Sn accumulation, followed by the liver, kidney, and other tissues in broilers. In conclusion, the adverse effects on broilers were induced when diets supplemented with Sn up to 480 mg/kg. Sn levels also managed to accumulate in the tibia and feather of broilers.

“…This was calculated using the slope ratio of the linear calibration plot of the SPE-ICP-OES method in comparison to ICP-OES without the SPE method. The LOD value obtained in this study was 0.6 ng mL -1 which is comparable with the values reported in the literature as follows: 1.1 and 0.7 ng mL -1 for solid and liquid samples, respectively, by preconcentration on Saccharomyces cerevisiae and determination by ICP-OES (1), 8.4 ng mL -1 by FAAS after micelle mediated extraction (14), 0.04 ng mL -1 by quartz atom traphydride generation AAS (31), 2.86 ng mL -1 by cloud point extraction before AAS measurement (2), 0.012 ng mL -1 by graphite furnace AAS after cloud point extraction (4), and 1.5 ng mL -1 by electrochemical hydride generation atomic fluorescence spectrometry using polyaniline-modified lead cathode (32).…”
