Two sisters and their brother who had been exposed to mercury vapours from a broken fever thermometer were treated for acrodynia. Their urinary Hg concentrations, as well as the relatively few data that can be found in previous publications, show that the brain of children below the age of 5 years is much more sensitive to chronic mercury intoxication than the cerebrum of adults. Hg concentrations of well below 50 micrograms/l in the urine can be associated with severe symptoms. One of our patients had a mercury concentration of 6.3 micrograms/l. In adults with occupational exposure, urinary mercury concentrations of up to 200 micrograms/l are tolerated and permitted. Acrodynia possibly is not always diagnosed when it is occurring. Normal values for urinary Hg excretion in children under basal conditions and after administration of a chelating agent should be established.
两名姐妹及其兄弟因一支破损的体温计泄漏汞蒸气而接触汞，他们接受了肢痛症治疗。他们的尿汞浓度，以及先前出版物中能找到的相对较少的数据表明，5岁以下儿童的大脑对慢性汞中毒比成人大脑更为敏感。尿汞浓度远低于50微克/升也可能出现严重症状。我们的一名患者汞浓度为6.3微克/升。在职业暴露的成年人中，尿汞浓度高达200微克/升仍可耐受且被允许。肢痛症发作时可能并非总能被诊断出来。应确定儿童在基础条件下及使用螯合剂后的尿汞排泄正常值。
