摘要
目的 调查我国一般人群血和尿中锰、钴、钼水平，分析其人群分布特点。方法 至2010年，在我国东部、西部和中部8个省份的24个市县，采用整群随机抽样的方法抽取了18120名6～60岁人群为研究对象，对其生活习惯和健康状况进行了问卷调查，并分别采集其静脉抗凝血样和尿样。用电感耦合等离子体质谱法对血样和尿样进行锰、钻、钼含量检测，通过统计学分析不同年龄、性别人群血和尿中锰、钴、钼水平的分布。结果 我国一般人群血锰几何均数为8．98μg／L，男性和女性血锰几何均数分别为8．14、9．88μg／L（Z=-18．84，P〈0．01）；尿锰几何均数为0．63μg/L，男性和女性尿锰几何均数分别为0．62、0．63μg/L（Z=-0．67，P〉0．05）；血钴几何均数为0．194μg／L，男性和女性血钴几何均数分别为0．166、0．225μg/L（Z=-23．04，P〈0．01）；尿钴几何均数为0．282μg/L，男性和女性尿钻几何均数分别为0．260、0．307μg/L（Z=-7．35，P〈0．01）；血钼几何均数为0．25μg/L，男性和女性血钼几何均数分别为0．27、0．23μg/L（Z=-5．03，P〈0．01）；尿钼几何均数为27．7μg/L，男性和女性尿钼几何均数分别为29．8、25．6μg/L（Z=-6．31，P〈0．01）。结论 我国一般人群血和尿中锰、钴、钼水平存在性别及地区差异。
Objective To evaluated the manganese （ Mn）, cobalt （Co） and molybdenum （Mo） levels in blood and urine among general population in China, and thereby to analyze their prevalent features. Methods From 2009 to 2010, a total of 18 120 subjects of general population aged 6-60 years were recruited from 24 districts in 8 provinces in eastern, central and western China mainland, by cluster random sampling method. The information about their living environment and health status were collected by questionnaire, and their blood and urine samples were also collected. Inductive coupled plasma mass spectrometry （ICP-MS） was applied to test the Mn, Co and Mo levels of blood and urine samples, and the Mn, Co, Mo distribution in blood and urine among groups of population in different ages and genders were then analyzed. Results Among general population in China, the geometric mean （GM） of Mn concentration in blood was 8.98 μg/L. The Mn concentration in blood among males and females were separately 8.14 μg/L and 9.88 μg/L （Z = -18.84, P 〈 0.01 ）. The GM of Mn concentration in urine was 0. 63 μg/L. The Mn concentration in urine among males and females were separately 0. 62μg/L and 0. 63 μg/L （ Z = - 0. 67, P 〉 0. 05 ）. The geometric mean （ GM ） of Co concentration in blood was 0. 194μg/L. The Co concentration in blood among males and females were separately 0. 166 μg/L and 0. 225 μg/L （ Z = - 23.04, P 〈 0. 01 ）. The GM of Co concentration in urine was 0. 282 μg/L. The Co concentration in urine among males and females were separately 0. 260μg/L and 0. 307 μg/L （Z = - 7. 35, P 〈 0. 01 ）. The GM of Mo concentration in blood was O. 25μg/L. The Mo concentration in blood among male and female group were separately O. 27 μg/L and 0. 23μg/L （ Z = - 5.03, P 〈 0. 01 ）. The GM of Mo concentration in urine was 27.7 μg/L. The Mo concentration in urine among males and females were 29. 8μg/L and 25.6 μ/L （ Z =- 6. 31,P 〈 0. 01 ） , respectively. Conclusion The Mn, Co and
