前言

本文件按照GB/T1.1—2020《标准化工作导则第1部分：标准化文件的结构和起草规则》的规

定起草。

本文件是GB/T22105《土壤质量总汞、总砷、总铅的测定原子荧光法》的第2部分。GB/T22105

已经发布了以下部分：

——第1部分：土壤中总汞的测定；

——第2部分：土壤中总砷的测定；

——第3部分：土壤中总铅的测定。

本文件代替GB/T22105.2—2008《土壤质量总汞、总砷、总铅的测定原子荧光法第2部分：

土壤中总砷的测定》，与GB/T22105.2—2008相比，除结构调整和编辑性改动外，主要技术变化如下：

——增加了多孔电热消解设备（见6.4，2008年版的第4章）；

——增加了样品的要求（见第7章）；

——更改了试样的制备（见8.1，2008年版的5.1）；

——更改了结果表示（见9.2，2008年版的第6章）；

——增加了质量保证和控制措施（见10.1、10.2，2008年版的第7章）；

——更改了精密度和正确度（见10.3、10.4，2008年版的第7章）；

——增加了“试验报告”（见第11章）；

——更改了检出限（见第12章，2008年版的第1章）；

——增加了定量限（见第12章）。
