摘要:
按照《国家地表水环境质量监测网监测任务作业指导书(试行)》中实验室分析测试的质量保证和质量控制要求,结合江苏省南京环境监测中心的实际工作,综合分析2017年10月—2018年8月间国家地表水采测分离工作中环境标准样品在样品测试准确度验证、检测人员能力确认、检测设备期间核查及关键化学试剂检查等方面的应用情况。为保障环境监测结果量值溯源的统一性、准确性、一致性和可比性,提出丰富水环境标准样品的浓度水平、解决标准样品供需不平衡问题、改善消耗量大的标准样品操作方法、建立环境标准样品使用信息共享平台等实践建议,为合理提升环境标准样品应用效能、有效保证水环境监测数据质量提供参考。

Abstract:
According to the quality assurance and quality control requirements of ‘The monitoring task instructions on national surface water environmental quality monitoring network(Trial)’, and combining with the practice of Jiangsu Nanjing Environmental Monitoring Center during October 2017 to August 2018, this paper has comprehensively analyzed the application of environmental quality control(QC) samples in verification of testing accuracy, confirmation of personnel capability, intermediate check of equipment, key chemical reagent check and so on. In order to guarantee the results quality of the environmental monitoring have traceability, accuracy, consistency and comparability, we suggest that the concentration level of environmental QC samples should be expanded, the operation method of large consumption QC samples should gradually be improved and the application information sharing 〖JP2〗platform of environmental QC samples should be built, etc. In conclusion, they could provide reliable reference for reasonably im〖JP2〗proving the application efficiency of environmental QC samples and effectively ensure the quality of water environmental monitoring data.
