A 30-year-old female dentist was exposed to mercury vapour from a leaking amalgamator for approximately one year. No toxic effect was noted. During and after the exposure urine samples were regularly taken for mercury analysis. The highest value during this period was 60 micrograms Hg/l urine (expressed in micrograms/g creatinine: 42; the normal value for unexposed persons is a few micrograms/g creatinine). The mercury concentration in air was at most 840 micrograms/m3 at the amalgamator (threshold limit for occupational exposure: 50 micrograms/m3). The dentist became pregnant and during pregnancy her average urine mercury concentration was 18 micrograms/g creatinine. Ultrasound examination of the fetus at 20 weeks of gestation showed a mild bilateral hydronephrosis. At 32 weeks of gestation the hydronephrosis had resolved. The dentist gave birth to a normal-weight baby boy, who, at the time of writing, is 2 years of age and appears clinically healthy.
一名30岁的女牙医接触泄漏汞合金搅拌机产生的汞蒸气约一年时间,未发现中毒症状。接触期间及之后定期采集尿液样本进行汞分析。在此期间尿液中汞的最高值为60微克/升(以微克/克肌酐表示为42;未接触者的正常值为几微克/克肌酐)。搅拌机处空气中汞浓度最高达840微克/立方米(职业接触限值为50微克/立方米)。该牙医怀孕了,孕期她尿液中汞的平均浓度为18微克/克肌酐。妊娠20周时对胎儿进行超声检查显示轻度双侧肾积水。妊娠32周时肾积水已消退。该牙医产下一名体重正常的男婴,在撰写本文时,该男婴2岁,临床检查健康。
