  • Title: Factors affecting the levels reported for vanadium in human serum.
    Author: Heydorn K.
    Journal: Biol Trace Elem Res; 1990; 26-27():541-51. PubMed ID: 1704761.
    Abstract:
    Chemometric techniques may be applied to extract significant analytical information from a series of publications that present methods and results for determining trace elements in biological material. This approach was applied to the total of 28 papers published in 1971-1988 that reported determination of vanadium in normal human serum or plasma; the levels spanned four orders of magnitude. The most important factors affecting the analytical results were found to be the choice of analytical method and the experience of the laboratory in trace-element research. Results from the most experienced laboratories with the best analytical methods were found to be correlated with the precision of the data, indicating that the correct concentration of vanadium would be less than 1 mg/m3. This is in agreement with results subsequently obtained by radiochemical neutron activation analysis of eight samples of serum from Danish colleagues.
