“…The contents of Mo, Cu, Zn, and Fe in the serum, liver, kidney, lung, cardiac muscle, hair, and muscle were analyzed via graphite furnace atomic absorption spectrometry (model 5100, HGA-600 Graphite Furnace; Perkin-Elmer, USA) [16]. The device working parameters (air, acetylene, optics, and electronics) were adjusted for maximum absorption for each element.…”

Molybdenum (Mo) is an essential trace element for animals and human beings. However, the negative effects on rumen function and distribution of trace elements in tissues induced by excessive Mo have not been well understood. Therefore, the purpose of present study was to investigate the impact of Mo on rumen microbiota, distribution of trace elements in various organs, and hematological parameters of goats. A total of 36 goats were randomly distributed into three groups with equal number and low-Mo and high-Mo groups were orally administered ammonium molybdate at 15 and 45 mg · Mo · kg · BW respectively, while the control group received corresponding quantitative deionized water. The results showed that the total number of ciliate and protozoa protein concentration decreased significantly (P < 0.01) on days 25 and 50. Concentrations of ammonia nitrogen and bacterial protein were significantly higher (P < 0.05) in low-Mo group, while they were lower (P < 0.05) in high-Mo group than the control group on days 25 and 50. In addition, Mo accumulated in serum and all detected tissues. Copper (Cu) and zinc (Zn) contents significantly decreased (P < 0.05) in hair and serum on days 25 and 50, while Cu contents increased (P < 0.05) and the change of Zn contents were not obvious (P > 0.05) in other tissues on days 25 and 50. Besides, there was no obvious variation in iron (Fe) contents during whole experiment period (P > 0.05). Furthermore, excessive Mo content had no significant effect on red blood cell (RBC) counts and hemoglobin (HGB) concentration (P > 0.05) on days 25 and 50, while white blood cell (WBC) counts increased significantly (P < 0.05) on day 50. These results indicated that excessive Mo content could impact the balance of ruminal microorganisms and interfere with the absorption and distribution of Mo and Cu mainly.

A preconcentration-separation procedure has been established based on solid-phase extraction of Fe(III) and Pb(II) on bucky tubes (BTs) disc. Fe(III) and Pb(II) ions were quantitatively recovered at pH 6. The influences of the analytical parameters like sample volume, flow rates on the recoveries of analytes on BT disc were investigated. The effects of co-existing ions on the recoveries were also studied. The detection limits for iron and lead were found 1.6 and 4.9 μg L⁻¹, respectively. The validation of the presented method was checked by the analysis of TMDA-51.3 fortified water certified reference material. The presented procedure was successfully applied to the separation-preconcentration and determination of iron and lead content of some natural water and herbal plant samples from Kayseri, Turkey.

“…The increases in the concentration of iron in the body have negative effects including endocrine problems and diseases of the liver, lung and other diseases [11][12][13][14]. The previous literature review conducted to determine the iron element in various samples by using cloud point extraction method that is coupled with different techniques such as: flame atomic absorption spectrometry (FAAS) [12,15,16], UV-visible spectrophotometer [17,18], inductively coupled plasma mass spectrometry [19], graphite furnace atomic absorption spectrometry [20] and capillary electrophoresis [21].…”

Cloud point technique used effectively for extraction and pre-concentration of iron(III) in the urine samples of occupational workers prior measured by using flame atomic absorption spectrometry and UV-visible spectrophotometer. The metal responds with benzidine as reagent in a non-ionic surfactant Triton X-114 medium. The main factors affecting cloud point extraction efficiencies, such as pH of sample solution, concentration of benzidine reagent, type of surfactant, concentration of Triton X-114, effect of salt out, influence of interferences and impact of equilibration temperature and time were studied. The calibration curve was linear in the range of 0.25-3.0 µg mL -1 with r 2 = 0.9655 for UV-visible spectrophotometer at λmax 425 nm. The limit of detection was 0.25 µg mL -1 . The relative standard deviation for six replicates was 3.071 %.
