【摘要】：为了解南昌市儿童体内铅、砷、镉含量的分布情况及其影响因素,于2014年采集南昌市近郊3所小学8~10岁共176名儿童的静脉血,采用电感耦合等离子质谱法(ICP-MS)测定儿童全血中铅、砷、镉、钙、铁、锌、锰、硒、铜的含量。结果显示,儿童血铅的中位数为47.00μg/L(范围:1.75~253.00μg/L),铅中毒(≥100μg/L)率为17.61%;血砷的中位数为6.30μg/L(范围:1.20~390.33μg/L);血镉检出11人(检出限为0.009 5μg/L),中位数为3.77μg/L(范围:2.39~19.04μg/L),有3例儿童超标(5μg/L)。男童血铅含量高于女童(P=0.028),男女童血砷、血镉含量差异无统计学意义(P0.05)。经多重线性逐步回归分析显示,儿童血铅与血砷呈正相关,与血锰呈负相关;儿童血砷与家庭经济水平呈负相关。提示被调查地区儿童存在血铅、血镉超标现象,元素之间的相互关系也应受到关注。
[Abstract]:In order to understand the distribution of lead, arsenic and cadmium in children in Nanchang city and its influencing factors, the venous blood samples of 176 children aged from 8 to 10 years old in 3 primary schools in the suburbs of Nanchang city were collected in 2014. The lead in whole blood of children was determined by inductively coupled plasma mass spectrometry (ICP-MS). Arsenic, cadmium, calcium, iron, zinc, manganese, selenium, copper. The median of blood lead in children was 47.00 渭 g / L (range: 1.75 卤253.00 渭 g / L), lead poisoning rate (鈮，
