【摘要】 为了解深圳市盐田区住院儿童铅负荷及其影响因素,采用火焰原子吸收方法对本区372名1~14岁儿童进行血铅含量测定,根据美国疾病控制中心1991年标准将血铅水平分为六级,观察了不同程度铅负荷及其影响因素的关系。结果表明,血铅水平为(7.98±4.1)ug/dl,铅中毒流行率为38.7%。提示盐田区1~14岁儿童铅中毒以轻度为主。更多还原

【Abstract】 To estimate blood lead level in 372 children ages ranged from 1 to 14 years old in Yantian District, and to identify high-risk factors of lead poisoning among the children. The blood lead levels and 42 potentially related factors involved in Yantian District’s children were studied. The mean blood lead level was 7.98 ug/dl, and 144 children (38.7%) were found with a blood lead level≥10 ug/dl (the diagnostic criterion of lead poisoning of children). Blood lead level varied with ages. Blood lead levels of children also varied in relation to traffic ways, parents’ education status, color pictures and secondary smoking exposure and the frequency of eating preserved alkaline eggs. Blood lead levels of children aged 1～14 years in Yantian District showed that the prevalence of lead poisoning were mainly mild type.更多还原
