In order to improve the quality of the results in sediment analysis, the Community Bureau of Reference (BCR) of the European Communities has developed 3 sediment reference materials (CRM) from estuarine, lake and river origins. Certification of mercury content in these materials was achieved by 3 methods (cold vapor atomic absorption spectrometry, plasma emission spectrometry, neutron activation analysis with radiochemical separation). The values finally certified in the CRM estuarine, lake and river sediments are 1.77 +/- 0.06, 0.67 +/- 0.02, 1.03 +/- 0.13 mg/kg respectively.
为提高沉积物分析结果的质量，欧洲共同体标准物质与测量研究所（BCR）制备了3种分别来源于河口、湖泊和河流的沉积物标准物质（CRM）。这些物质中汞含量的定值采用了3种方法（冷蒸气原子吸收光谱法、等离子发射光谱法、放射化学分离中子活化分析法）。最终定值的河口、湖泊和河流沉积物标准物质中汞的含量分别为1.77±0.06、0.67±0.02、1.03±0.13mg/kg。
