摘　　要：针对地质样品中的金属元素异常,采用化学光谱仪、碱溶ICP-MS法和原子吸收光谱仪等多种分析技术,对地质样品中的金属元素进行定量分析。研究涉及的关键金属元素包括铜(Cu)、锌(Zn)、铅(Pb)和镉(Cd)。其中,铜和锌的平均质量浓度分别为320μg/L和285μg/L,显示出特定地质样品中金属元素的显著富集。此外,铅和镉的检测结果揭示了潜在的环境风险,其质量浓度分别为55μg/L和2.5μg/L,超过了自然背景值。通过对这些数据的分析,不仅提高了对金属元素异常信息提取的准确性和效率,也为评估其地质来源和环境影响提供了科学依据,对于理解地球化学过程、环境监测和资源评估具有重要意义。In response to the metal element anomalies in geological samples,various analytical techniques such as chemical spectrometer,alkali soluble ICP-MS method,and atomic absorption spectrometer were used to quantitatively analyze the metal elements in geological samples.The key metal elements involved in the study include copper(Cu),zinc(Zn),lead(Pb),and cadmium(Cd).Among them,the average mass fractions of copper and zinc were 320μg/L and 285μg/L,respectively,indicating significant enrichment of metal elements in specific geological samples.In addition,the detection results of lead and cadmium revealed potential environmental risks,with mass fractions of 55μg/L and 2.5μg/L,respectively,exceeding the natural background values.Through the analysis of these data,not only has the accuracy and efficiency of extracting anomalous information of metal elements been improved,but also a scientific basis has been provided for evaluating their geological sources and environmental impacts,which is of great significance for understanding geochemical processes,environmental monitoring,and resource assessment.
