为了掌握土壤检测实验室的重金属检测能力和检测结果的可比性,采用国际上通用的稳健统计,用＂Z比分法＂统计方法对土壤中汞、镉、铜的检测结果进行分析。结果表明：3个土壤样品实验室铜测定结果满意度为100%;汞检测结果的满意度为66.7%～88.9%,可疑结果率为11.1%～16.7%,不满意率为0%～22.2%;镉检测结果的满意度为83.3%～88.9%,可疑结果率为0%～11.1%,不满意率为0%～16.7%;结论：参加此次比对试验的实验室铜检测能力较高,部分实验室汞和镉检测能力有待于提高。

In order to master the testing capability and result comparability of soil heavy metal inspection labs.This paper adopts the internationally acknowledged statistical method with ＂Z-score＂ to analyze the testing results of Hg,Cd and Cu in the soil.The results show that the copper testing in three labs were all satisfactory.The satisfactory rate of Hg and Cd were 66.7%~88.9% and 83.3%~88.9%,questionable rate were11.1%~16.7% and 0%~11.1%,dissatisfactory rate were 0%~22.2% and 0%~16.7%,respectively.The general testing capability on Cu is relative high for all labs that took part in the comparison tests However,part of the laboratory testing of Hg and Cd testing capabilities needs to be improved.
