Abstract

Human hair is a significant biological sample in forensic science, biomedical research, and the cosmetic industry, with the presence of essential nutrients like zinc, copper, and silicon being indicative of health. This study aimed to investigate the elemental composition of human hair using Laser-Induced Breakdown Spectroscopy (LIBS) to assess differences across age groups. Nine volunteers provided hair samples, which were analyzed using the Foster + Freeman ECCO2 LIBS system. Quantitative analysis of elemental concentrations was performed, and elemental ratios, such as Mg/Ca, Mg/Si, Mg/Fe, and Fe/Mn, were calculated to compare the samples. Results demonstrated that LIBS is a fast, accurate, and non-destructive method for detecting and quantifying mineral elements in human hair. The study highlights age-related differences in elemental concentrations, offering insights into the use of hair analysis for monitoring nutritional and health status. LIBS could be a promising tool for further studies in clinical and forensic applications.

人发激光诱导击穿光谱研究：人发中含量元素的定性和定量分析

人类头发是法医学、生物医学研究和化妆品行业中的重要生物样本，其中含有的锌、铜和硅等必需营养物质是健康的标志。本研究旨在利用激光诱导击穿光谱法（LIBS）调查人类头发的元素组成，以评估不同年龄组的差异。九名志愿者提供了头发样本，并使用 Foster + Freeman ECCO2 LIBS 系统对其进行了分析。对元素浓度进行了定量分析，并计算了元素比率，如 Mg/Ca、Mg/Si、Mg/Fe 和 Fe/Mn，以便对样本进行比较。结果表明，LIBS 是一种快速、准确、非破坏性的检测和量化人类头发中矿物质元素的方法。该研究强调了与年龄有关的元素浓度差异，为利用毛发分析监测营养和健康状况提供了启示。在临床和法医应用方面，LIBS 可能是一种很有前途的进一步研究工具。
