摘　　要：收集健康大学生的指甲,采用微波消解、电感耦合等离子体发射光谱仪(ICP-OES)测定指甲中微量元素的含量。结果显示指甲中Fe,Zn,Cu,Mn的含量分别为39.12±57.89μg/g,118.83±30.40μg/g,7.11±4.24μg/g和0.66±0.78μg/g。指甲中Fe含量女性显著低于男性(P<0.05)。方法简便、灵敏、准确,结果较好地反映了在校大学生的健康状况,同时也为指甲作为生物样本的可行性提供基础数据。Healthy university students＇ fingernails were collected and some mieroelement levels were determined by inductively coupled plasma optical emission spectrometer （ICP - OES）. As a result, the levels of Fe, Zn, Cu, Mn in fingernails were 39. 12 ±57.89 μg/ g, 118.83 ±30.40 μg/g, 7. 11 ±4.24 μg/g and 0. 66 ±0.78 μg/g, respectively. The level of Fe was significantly lower in female students than in male students. As an accuracy and simple method, it reflects the healthy condition of university students and also provides the basic data for fingernails as biomarkers.
