Wpływ czynników chemicznych na strukturę i budowę włosów ludzkich

The main purpose of the presented study was to investigate the influence of chemical factors on the morphology of human hair. Few factors that may occurduring criminal offenses were selected for testing, including aqueous solutions of hydrochloric acid (HCl), sodium hydroxide (NaOH), lead(II) nitrate (Pb(NO₃)₂), cadmium(II) nitrate (Cd(NO₃)₂), sodium chloride (NaCl), ethanol (C₂H₅OH), water (H₂O). The description of the effects of chosen chemical compounds on hair was made mainly on the basis of Scanning Electron Microscopy (SEM). In addition, the elemental composition of the hair as an effect of interaction with solution was examined and analyzed using an EDX (Energy - Dispersive X-ray) spectrometry. Performed tests show the degree of human hair degradation and contamination depending on the examined factor and time.
