Hexavalent chromium in cement 5-8 mg/kg hexavalent chromium (Cr(VI)) was found in Honduran cement samples, which was slightly higher than in Swedish samples. Variable amounts of Cr(VI) (0.4 and 4.7 mg/kg) found in Swedish cement samples that were older than 1 year. There are still many countries that do not have a compulsory reduction of Cr(VI) in cement. Several measures can be employed to reduce risks related to Cr(VI) in cement.
水泥中的六价铬 洪都拉斯水泥样本中发现了 5-8 毫克/千克的六价铬（Cr(VI)），略高于瑞典样本。在瑞典，1 年以上的水泥样本中发现了不同量的 Cr(VI)（0.4 和 4.7 毫克/千克）。仍有许多国家没有强制要求减少水泥中的 Cr(VI)。有几种措施可以用来降低与水泥中的 Cr(VI)相关的风险。
