摘要
为掌握全省各驻市生态环境监测中心的能力水平,持续提高生态环境监测数据质量,山东省生态环境监测中心组织开展了2020年度土壤重金属元素检测能力验证工作。本次能力验证采用单因子方差分析法和相对标准偏差法对样品的均匀性进行检验,采用稳健统计方法和Z比分数对实验室检测结果进行分析评价。结果表明,土壤中铜、镉结果满意率为93.8%,各驻市生态环境监测中心土壤重金属元素检测能力总体较好。
In order to master the capacity level of Eco-environmental Monitoring Centers in Shandong province and continuously improve the quality of eco-environmental monitoring data,Shandong Provincial Eco-environment Monitoring Center organized the proficiency testing of heavy metal elements in soil in 2020.Single factor analysis of variance and relative standard deviation method were used to test the uniformity of samples,and robust statistical method and Z-score were used to analyze and evaluate the laboratory test results.The results showed that the satisfaction rate of copper and cadmium in soil was 93.8%,and the ability of heavy metal elements detection in soil of Eco-environmental Monitoring Centers were generally good.
