High-precision measurements of natural variations in the stable isotopic composition of mercury show great promise as a new tracer of mercury sources and chemical transformations in the environment. We strongly suggest that all laboratories adopt a common means of data correction, standardization, and nomenclature in order to ensure that data from various laboratories can be easily evaluated and compared. We make suggestions for mass bias correction, reporting of mass-dependent and mass-independent isotope variations, and a standard protocol for reporting analytical uncertainties. We also present our measured values for isotope ratios in several mercury standard solutions.
汞稳定同位素组成自然变化的高精度测量作为汞源和环境中化学转化的新示踪剂显示出巨大潜力。我们强烈建议所有实验室采用统一的数据校正、标准化和命名方法，以确保不同实验室的数据能够易于评估和比较。我们对质量偏倚校正、质量依赖和质量独立同位素变化的报告以及分析不确定度报告的标准协议提出了建议。我们还给出了几种汞标准溶液的同位素比值测量值。
