本文针对56个海洋行业监测检测实验室进行的海洋生物体中As和海洋沉积物中Cd含量测定结果,采用稳健统计技术(Robust statistical technique)方法进行了评价分析。结果表明,参加本次能力验证活动的大多数实验室检测能力良好,其出具的检测数据可信。少数实验室检测结果有问题或不满意,鼓励这些实验室认真查找问题,积极采取纠正措施,改进实验室管理和质量控制,提升并保持检测能力。研究表明,稳健统计技术在本次实验室能力验证结果评价中应用效果良好,真实全面的反应了各实验室检测能力现状。
In this paper, 56 marine industrial monitoring laboratories for marine organisms in As and marine sediment determination of Cd content, the use of robust statistical techniques (Robust statistical technique) method were evaluated. The results show that most laboratories participating in this proficiency testing activity have good testing capabilities and the test data they produce are credible. A few laboratory test results have problems or are not satisfied, encourage these laboratories to seriously find problems, and actively take corrective measures to improve laboratory management and quality control, enhance and maintain the detection capability. The research shows that the robust statistical techniques have good effect in the evaluation of the laboratory proficiency testing results and truly and completely reflect the current status of the laboratory testing capabilities.
