浅谈环境监测化学测量结果的计量溯源性

Review of Metrological Traceability in Chemical Measurement of Environmental Monitoring

确保测量结果的计量溯源性是保障数据有效性的基本要求。为此,国家明确提出要建立健全国家生态环境监测量值溯源体系。化学测量是环境监测工作中最常用的一种测量方式。由于基体、浓度等的影响往往比较复杂,如何确保环境监测化学测量结果的计量溯源性成为环境监测领域的重要研究内容。通过总结建立环境监测化学测量结果计量溯源性的途径,对环境监测分析方法标准、国家环境标准样品、环境检测能力验证等在保证环境监测化学测量结果计量溯源性中的作用进行了分析,以期为环境监测化学测量结果计量溯源性的建立提供参考。

Metrological traceability assures the inter-comparability of measurement results globally.Metrological traceability of measurement results is basic requirements to ensure availability of environmental monitoring data.To establish and improve the national traceability system for ecological environment monitoring is explicitly requested.Chemical measurement is one of the most common ways of environmental monitoring.Environmental chemiacal measurements concern a wide rang of matrices and various levels of concentrations,and the complexity of the measurements is increasing.Essential activities are studied wihich are necessary to eastablish traceability in chemical measurement of environmental monitoring.The main features such as reference methods,reference materials,proficiency testing,have already been discussed,and provide a reference for the establishment of metrological traceability of chemical measurement results of environmental monitoring.
