摘要
目的 了解儿童血铅水平与胎儿期铅污染的关系。方法 采集 1～ 5岁儿童手指血和新生儿出生时的脐带血 ,用原子吸收石墨炉法测定血铅浓度。结果 112 2例儿童血铅平均为 (0 42± 0 15 ) μmol/L ,血铅值≥ 0 483μmol/L的儿童占 2 7 5 4% ;12 7例新生儿脐带血铅平均为 (0 16± 0 12 )μmol/L ,血铅值≥ 0 483μmol/L的新生儿占 0 79%。 结论 儿童血铅水平高主要是环境污染和生活行为引起 ,儿童在胎儿期血铅的本底水平已较高 。
Objective To study the relationship between blood lead level in children and fetus. Methods Blood specimens were collected from the fingers of children aged one to five years and from umbilical cord when the babies were born, to determine their lead level with atomic absorption spectrophotometry Results The average blood lead level was (0 42±0 15) μmol/L in 1 122 children Blood lead level in 27 54% of the children was above ≥0 483 μmol/L The average umbilical blood lead level was (0 16±0 12) μmol/L in 127 neonates Blood lead level in 0 79% of the new born babies were greater than ≥0 483 μmol/L. Conclusion Higher blood lead level in children was mainly caused by environmental pollution and unhealthy life behaviors Background blood lead in fetuses has already reached a higher level, so prevention from lead poisoning in children should begin during pregnancy
