The mercury content in hair of the population in Madrid (chosen randomly) was in the range of 1.29-129.47 micrograms/g (geometric mean = 7.96 micrograms/g). The mean mercury content in hair of occupationally exposed workers was 12.70 micrograms/g (range = 2.91-65.43 micrograms/g). The highest means, which were found in two families (i.e., 67.89 micrograms/g and 92.47 micrograms/g, Families A and B, respectively), probably resulted from external factors. No statistically significant variations in the mercury concentrations in hair were found with regard to sex, age, or dental fillings. A significant correlation (r = 0.785; P less than .01) was found between the concentration of the total mercury found in nursing infants and their mothers.
马德里随机选取人群头发中的汞含量在1.29 - 129.47微克/克范围内（几何平均值 = 7.96微克/克）。职业暴露工人头发中的汞平均含量为12.70微克/克（范围 = 2.91 - 65.43微克/克）。在两个家庭中发现了最高平均值（即分别为67.89微克/克和92.47微克/克，A家庭和B家庭），这可能是由外部因素导致的。在头发汞浓度方面，未发现性别、年龄或补牙情况存在统计学显著差异。在哺乳期婴儿及其母亲体内发现的总汞浓度之间存在显著相关性（r = 0.785；P < 0.01）。
