The main purpose of this paper is to use the laser-induced breakdown spectroscopy (LIBS) technique as a fast, noninvasive, and low cost spectro-biochemical analysis laser spectroscopy technique. This study will indicate the qualified performance of LIBS with the proposed optimum conditions as a promising and easy tool for identification, detection, and characterization of trace elements in different hair types. The purpose of the study is to show that due to the pollution of sites and environment by heavy metals being a significant public health risk, various diseases can be caused by these elements. The present work was conducted on various animal hair samples using the LIBS technique to evaluate the body elemental content through a segment of hair. Qualitative analysis was performed on atomic and ionic species of elementals such as Cu, Cd, Fe, Pb, Ni, Mn, Co, and Zn. To determine the quantitative analysis, the relative mass concentration was calculated as the ratio of atoms and ions of the selected elements of the reference element carbon, C, which is considered to be a reference element due to the internal standard matrix. These calculations provided the actual concentration of each element, which can be considered for further work.

使用激光诱导击穿光谱技术检测马毛和山羊毛的重金属

本文的主要目的是将激光诱导击穿光谱 (LIBS) 技术作为一种快速、无创、低成本的光谱生化分析激光光谱技术。这项研究将表明 LIBS 的合格性能和建议的最佳条件,作为一种有前途且简单的工具,用于识别、检测和表征不同头发类型中的微量元素。该研究的目的是表明,由于重金属对场地和环境的污染是一个重大的公共健康风险,这些元素可能导致各种疾病。目前的工作是使用 LIBS 技术对各种动物毛发样本进行的,以通过一段毛发评估身体元素含量。对元素的原子和离子种类进行了定性分析,例如 Cu、Cd、Fe、铅、镍、锰、钴和锌。为了确定定量分析,相对质量浓度被计算为参考元素碳的所选元素的原子和离子的比率,C,由于内标矩阵而被认为是参考元素。这些计算提供了每种元素的实际浓度,可以考虑用于进一步的工作。
