Abstract
Sweat contents were investigated for using those data to forensic purpose. The experiments of identifying sweat contents were as follow: 1) measurement of amino acids (aspartic acid, serine, glycine etc) by HPLC, 2) anions ($Cl^-$, $F^-$, and $SO{_4}^{2-}$) by IC and 3) trace elements (Cu, Zn, Li, B, etc.) by ICP-MS. Amino acid contents in sweat are varied with individual samples and glycine, threonine, alanine, valine and histidine are detected as the prime one. The detected anions are $Cl^-$(2167~4073 ppm) and $F^-$(454~582 ppm) mostly. Trace elements of Rb, Zn and Cu are detected and those concentrations are relatively very high. The compositions of sweat can be influenced by various factors (diet, anthropometric, characteristics, physical fitness, age, gender and the state of the health).
