目的掌握本地区新生儿、婴幼儿全血中锑的暴露水平。方法采用多阶段随机抽样法,抽取67例新生儿、婴幼儿的全血样本,经微波消解-氢化物发生原子荧光光谱法测定全血中锑暴露水平。运用统计学方法计算其特征参数。结果新生儿、婴幼儿血锑总检出率为92.5%;其最小值为未检出,最大值为29.7μg/L。平均值为9.77μg/L。P5~P95范围为ND~26.1μg/L。其性别、年龄差异无统计学意义(P>0.05)。结论本次调查掌握了本地区新生儿、婴幼儿血锑暴露水平,为保护新生儿、婴幼儿人群健康提供基础数据。
Objective To understand the levels of antimony in whole blood of newborns and infants in this area. Methods A total of 67 whole blood samples from newborns and infants were collected by multi-stage random sampling method. Antimony exposure in whole blood was determined by microwave digestion-hydride generation atomic fluorescence spectrometry. Use statistical methods to calculate its characteristic parameters. Results The total detection rate of antimony in neonates and infants was 92.5%. The minimum detectable value was 29.7 μg / L. The average was 9.77 μg / L. P5 ~ P95 ranged from ND ~ 26.1μg / L. The gender, age difference was not statistically significant (P> 0.05). Conclusion This survey grasped the levels of antimony in neonates and infants in this area and provided the basic data for protecting the health of infants and infants.
