ISO 17733:2015规定了工作场所空气中汞蒸气和无机汞化合物的时间加权平均质量浓度测定程序。汞蒸汽通过扩散管或泵吸吸附管收集在固体吸附剂上。颗粒无机汞化合物（如果存在）收集在石英纤维过滤器上。在收集的汞酸溶解后，使用冷蒸汽原子吸收光谱法（CVAAS）或冷蒸汽原子荧光光谱法（CVAFS）对样品进行分析。 本国际标准适用于空气中汞蒸气和/或颗粒无机汞化合物的个人暴露评估，以与汞和无机汞化合物的长期或短期暴露限值进行比较，并用于静态（区域）采样。 程序工作范围的下限为定量限。 这取决于用户选择的采样和分析方法，但通常在0.01μg至0.04μg汞的范围内（见13.1）。程序工作范围的上限由用于样品采集的扩散徽章、吸附剂管或过滤器的容量决定，但至少为30μg汞（见13.2）。本国际标准适用的空气中汞的浓度范围部分取决于用户选择的采样方法，但也取决于空气采样量。 当氯碱厂等大气中存在氯时，扩散式badge法不适用于汞蒸气的测量，但氯不会干扰泵吸吸附剂管法（见13.12.1）。气态有机汞化合物可能会对汞蒸气的测量产生正干扰（见13）。 12.2). 类似地，吸附在空气颗粒上的颗粒有机汞化合物和气态有机汞化合物可能会对颗粒无机汞化合物的测量产生正干扰（见13.12.3）。

ISO 17733:2015 specifies a procedure for determination of the time-weighted average mass concentration of mercury vapour and inorganic mercury compounds in workplace air. Mercury vapour is collected on a solid sorbent using either a diffusive badge or a pumped sorbent tube. Particulate inorganic mercury compounds, if present, are collected on a quartz fibre filter. Samples are analysed using either cold vapour atomic absorption spectrometry (CVAAS) or cold vapour atomic fluorescence spectrometry (CVAFS) after acid dissolution of the mercury collected. This International Standard is applicable to the assessment of personal exposure to mercury vapour and/or particulate inorganic mercury compounds in air for comparison with long-term or short-term exposure limits for mercury and inorganic mercury compounds and for static (area) sampling. The lower limit of the working range of the procedure is the quantification limit. This is determined by the sampling and analysis methods selected by the user, but it is typically in the range 0,01 μg to 0,04 μg of mercury (see 13.1). The upper limit of the working range of the procedure is determined by the capacity of the diffusive badge, sorbent tube or filter used for sample collection, but it is at least 30 μg of mercury (see 13.2). The concentration range of mercury in air for which this International Standard is applicable is determined in part by the sampling method selected by the user, but it is also dependent on the air sample volume. The diffusive badge method is not applicable to measurements of mercury vapour when chlorine is present in the atmosphere, e.g. in chloralkali works, but chlorine does not interfere with the pumped sorbent tube method (see 13.12.1). Gaseous organomercury compounds could cause a positive interference in the measurement of mercury vapour (see 13.12.2). Similarly, particulate organomercury compounds and gaseous organomercury compounds adsorbed onto airborne particles could cause a positive interference in the measurement of particulate inorganic mercury compounds (see 13.12.3).
