本文对重工业区——中国长城铝业公司幼儿园4~6岁儿童292人进行了血铅水平测定,同时测定该组儿童的身高、体重、头围、胸围、血色素及能力商,观察了血铅浓度与上述各指标的关系,结果表明该区儿童因铅均值为32.298μg/dl,血铅水平过高者达60%,经正态性D检验属正态分布,可以作为本地区4~6岁儿童血铅水平的本底值,经γ相关性检验血铅与身高等各项指标间呈现负相关。
In this paper, blood lead levels were measured in 292 children aged 4 ~ 6 years in the heavy industry zone - China Great Wall Aluminum Company kindergarten, and the height, weight, head circumference, chest circumference, hemoglobin and capacity of the children were also measured. The results showed that children in this area had a positive mean of 32.298 μg / dl and a blood lead level of 60%. Normal distributions of normal blood lead levels could be used as a measure for the regional distribution of 4-6 The background value of blood lead levels in children aged between 3 and 6 years showed a negative correlation between blood lead and body height by γ test.
