环境检测实验室的质量核查研究

环境检测实验室质量核查是实验室满足认证／认可准则的检查活动，是体系满足要求的证明性过程，环境实验室进行质量核查，是提高环境实验室检测质量的重要措施。本文主要从人员及设备、实验室外部影响因素核查（包括现场采样，样品保存和运输）、实验室内部影响因素（包括实验用水、实验空白和检出限、平行样及加标回收、标准样品、标准曲线等）核查等方面简述环境检查实验室质量核查的主要内容，为实验室质量核查提供借鉴。

Quality Inspection on Environment Assessment Laboratory

Quality inspection on environment assessment laboratory is a back - check to satisfy certification guidelines of the laboratory. It is one of the important measures to improve quality of laboratory testing. This study summarized the procedures of la- boratory quality inspection in terms of personnel, facility, external influencing factors （including on -site sampling, sample pres- ervation and transportation） and internal factors （ including experiment water, blank and detection limit, parallel samples and standard addition recovery, standard samples, standard curve, etc）. This paper provides reference for those who engaged in labo- ratory quality assessment.
