Abstract

Soil certified reference material (CRM), UME EnvCRM 03 was produced by a collaborative approach among national metrology institutes, designated institutes and university research laboratories within the scope of the EMPIR project: Matrix Reference Materials for Environmental Analysis. This paper presents the sampling and processing methodology, homogeneity, stability, characterization campaign, the assignment of property values and their associated uncertainties in compliance with ISO 17034:2016. The material processing methodology involves blending a natural soil sample with a contaminated soil sample obtained by spiking elemental solutions for 8 elements (Cd, Co, Cu, Hg, Ni, Pb, Sb and Zn) to reach the level of warning risk monitoring values specified for metals and metalloids of soils in Europe. Comparative homogeneity and stability test data were obtained by two different institutes, ensuring the reliability and back up of the data. The certified values and associated expanded uncertainties for the total mass fractions of thirteen elements (As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Sb, V and Zn) are established. The developed CRM can be used for the development and validation of measurement procedures for the determination of the total mass fractions of elements in soil and also for quality control/assurance purposes. The developed CRM is the first example of a soil material originating from Türkiye.

通过联合研究项目认证 UME EnvCRM 03 土壤样本中的总元素质量分数

土壤有证标准物质（CRM）UME EnvCRM 03 是在 EMPIR 项目范围内，由国家计量机构、指定机构和大学研究实验室合作生产的：环境分析基质参考材料。本文介绍了符合 ISO 17034:2016 标准的采样和加工方法、均匀性、稳定性、表征活动、属性值分配及其相关不确定性。材料处理方法包括将天然土壤样本与通过添加 8 种元素（镉、钴、铜、汞、镍、铅、锑和锌）元素溶液获得的污染土壤样本混合，以达到欧洲土壤金属和类金属的预警风险监测值水平。同质性和稳定性的比较测试数据由两个不同的机构获得，确保了数据的可靠性和支持性。确定了 13 种元素（As、Cd、Co、Cr、Cu、Fe、Hg、Mn、Ni、Pb、Sb、V 和 Zn）总质量分数的认证值和相关的扩展不确定性。所开发的有证标准物质可用于开发和验证测定土壤中元素总质量分数的测量程序，也可用于质量控制/保证目的。所开发的有证标准物质是首个源自土尔其的土壤材料实例。

期刊介绍： Accreditation and Quality Assurance has established itself as the leading information and discussion forum for all aspects relevant to quality, transparency and reliability of measurement results in chemical and biological sciences. The journal serves the information needs of researchers, practitioners and decision makers dealing with quality assurance and quality management, including the development and application of metrological principles and concepts such as traceability or measurement uncertainty in the following fields: environment, nutrition, consumer protection, geology, metallurgy, pharmacy, forensics, clinical chemistry and laboratory medicine, and microbiology.
