Abstract

Sweat contents were investigated for using those data to forensic purpose. The experiments ofidentifying sweat contents were as follow: 1) measurement of amino acids (aspartic acid, serine, glycine etc)by HPLC, 2) anions (Cl, F , and SO42) by IC and 3) trace elements (Cu, Zn, Li, B, etc.) by ICP-MS. Aminoacid contents in sweat are varied with individual samples and glycine, threonine, alanine, valine and histidine (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 compositionsof sweat can be influenced by various factors (diet, anthropometric, characteristics, physical fitness, age, genderand the state of the health).
