The research of the reference value of urinary mercury for 0-6 years old children in coast area [PDF]
, 2015 目的通过对厦门市0~6岁儿童尿汞水平调查,了解厦门市儿童汞暴露水平。方法根据行政区划以及儿童人数分布从全市选取代表性的8个社区,进行分层随机抽样,共收集到1076例0~6岁儿童尿样。样本采用随意尿,每个儿童统一使用聚乙烯塑料瓶收集不少于5 M l尿样,尿样统一采用dMA-80自动测汞仪测定。结果儿童尿汞测定值呈偏态分布,因此使用几何平均数表示儿童尿汞的平均水平。男女儿童尿汞几何平均值分别为0.77μg/l和0.74μg/l,经非参数T检验比较,差异无统计学意义(P>0.05)。0~1岁、2~3岁和3 ...
