环境标准样品的选择与使用研究

Study on Selection and Use of Environmental Reference Material

环境监测数据是客观评价环境质量状况、反映污染治理成效、实施环境管理与决策的基本依据,我国高度重视环境监测数据质量。环境标准样品是确保环境监测数据质量的重要工具,广泛应用于我国环境监测活动中,为监测数据的一致性、可比性和准确性提供了重要的技术支撑。简要介绍了环境标准样品的定义、分类、特性及特性值,探讨了环境标准样品的选择,并根据环境标准样品的应用,对环境标准样品在待测环境样品赋值、测量方法/程序的确认、环境监测质量控制等方面的使用进行了综述,为环境监测机构正确选择和使用环境标准样品提出相关建议。

Environmental monitoring data is the basic basis for objectively evaluating environmental quality,which reflected the effectiveness of pollution control,and implemented environmental management and decision-making.China attaches great importance to the quality of environmental monitoring data.Environmental Reference Material is important tool to ensure the quality of environmental monitoring data,and widely used in environmental monitoring in China.It provides important technical support for the consistency,comparability and accuracy of monitoring data. The definition,classification,characteristics and characteristic values of Environmental Reference Material was introduced,and the selection of environmental standard samples was discussed. Based on the application of Environmental Reference Material,the use of Environmental Reference Material were studied,such as calibration of environmental monitoring instruments,assign values to the Environmental Reference Material,confirmation of measurement method/procedure,and quality control for environmental monitoring.And put forward some suggestions on selection and use of Environmental Reference Material by environmental monitoring agency.
