“…The selenium levels in our study were relatively higher than previously published data [15][16][17]. It was probably because the subjects we selected here were mostly from Zhoushan, a coastal city in Zhejiang province.…”

“…This result agrees with a research conducted in Belgium [6] which revealed selenium blood concentration equal to 79.7 ng•mL -1 , ranging from 55 to 117.4 ng•mL -1 , with no significant difference between gender. However, in a research conducted in Canada [12] there was difference between Selenium levels in men and women blood, 137 ng•mL -1 and 127.2 ng•mL -1 , respectively.…”

Selenium is an element which participates in antioxidant enzymes. A medium and long term lack of such element is associated, mainly, with heart disease, joint and bone structure problems and thyroid activity. Selenium contents in blood reflect its ingestion and food content variation. It depends on soil characteristics, such as pH and selenium presence. There are few studies concerning selenium levels in food and blood in Brazil. Therefore, the objective of this research was to determine selenium content in a blood donor group in Rio de Janeiro state, conducted from December 2008 to March 2009. From the donated blood to Regional Blood Center of Campos dos Goytacazes, 4.0 mL were submitted to selenium analysis through atomic absorption spectrometry of hydride generation and organic matter oxidation wet basis with nitric and perchloric acid. Selenium content varied from 75 ± 16 ng·g-1 for females and 70 ± 21 ng·g-1 for males. There was no significant difference among selenium contents in blood from donors of different gender, age and residence. Seventy four percent of donors had selenium content in blood below 70 ng·mL-1, the lowest level for maximum selenoproteins production, according to the Nutritional Prevention Cancer

Determination of aluminum (Al), beryllium (Be), cadmium (Cd), chromium (Cr), mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb), and thallium (Tl) concentrations in human blood using high-frequency modulation polarization Zeeman graphite furnace atomic absorption spectrometry (GFAAS) was performed. No sample digestion was used in the current study. Blood samples were diluted with deionized water or 0.1 % (m/v) Triton X-100 solution for Tl. Dilution factors ranged from 1/5 per volume for Be and Tl to 1/20 per volume for Cd and Pb. For Tl, Cd, and Hg, noble metals (gold, platinum, rhodium, etc.) were applied as surface modifiers. To mitigate chloride interference, 2 % (m/v) solution of NH(4)NO(3) was used as matrix modifier for Tl and Ni assessment. The use of Pd(NO(3))(2) as oxidative modifier was necessary for blood Hg and Tl measurement. Validation of the methods was performed by analyzing two-level reference material Seronorm. The precision of the designed methods as relative SD was between 4 and 12 % (middle of a dynamic range) depending on the element. For additional validation, spiked blood samples were analyzed. Limits of detection (LoDs, 3σ, n = 10) for undiluted blood samples were 2.0 μg L(-1) for Al, 0.08 μg L(-1) for Be, 0.10 μg L(-1) for Cd, 2.2 μg L(-1) for Cr, 7 μg L(-1) for Hg, 0.4 μg L(-1) for Mn, 2.3 μg L(-1) for Ni, 3.4 μg L(-1) for Pb, and 0.5 μg L(-1) for Tl. The LoDs achieved allowed determination of Al, Cd, Cr, Mn, Ni, and Pb at both toxic and background levels. Be, Hg, and Tl could be reliably measured at toxic levels only. The methods developed are used for clinical diagnostics and biological monitoring of work-related exposure.
