title: [Normal Range of 33 Elements in Blood Samples from General Population in Hunan Province].
abstract: OBJECTIVE
  To determine the normal range of the 33 elements (Li, Be, B, Mg, Al, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, As, Se, Rb, Sr, Zr, Mo, Ag, Cd, Sb, Cs, Ba Au, Hg, Tl, Pb, Th and U) in human whole blood of general population in Hunan province.
  
  
  METHODS
  Blood samples were analyzed by inductively coupled plasma-mass spectrometry (ICP-MS) to determine the normal range. The influences of district, gender and age to the element content in blood samples were also observed.
  
  
  RESULTS
  The normal range of 33 elements in blood samples from general population in Hunan province were obtained. Gender was shown to statistically influence the concentrations of B, Mg, Ca, Ti, Mn, Fe, Co, Cu, Zn, As, Se, Rb, Sr, Ag, Cd, Cs, Hg and Pb (P < 0.05), while age was shown to influence the concentrations of Co, Ni, Cs and Hg in women (P < 0.05) as well as Cu, Se and Hg in men (P < 0.05).
  
  
  CONCLUSIONS
  Although there are variables in different districts, the normal ranges of trace element in blood of the four cities in Hunan province are established.
