血铅水平的关系，环境和个人特征进行了分析，在一个大样本的铅冶炼复杂的附近居住的儿童，特别强调识别与年龄相关的危险因素。异常的变化，血铅及其决定因素在研究区域内促进了同时检测的几个重要的危险因素，每年的年龄从1-9岁。在所有年龄段的血铅最强的预测因素是空气铅，但次要危险因素是年龄依赖性。家庭灰尘是显着相关的血铅在幼儿，特别是那些在2岁以下的儿童，土壤铅可能是一个重要的来源，摄入铅的2至7岁之间的儿童。其他显著的影响包括异食癖在2岁左右，父亲的职业类别的5-8岁的儿童，和8和9岁的男孩有较高的血铅比同龄女孩的趋势轻微的影响。油漆中铅浓度不是一个显著的危险因素。这些结果表明，一个多因素的方法来预防儿童铅的过度吸收是必要的。
The relationship of blood lead levels to environmental and individual characteristics is analyzed in a large sample of children residing near a Pb smelting complex, with particular emphasis on the identification of age-related risk factors. Exceptional variation in both blood Pb and its determinants within the study region facilitated the simultaneous detection of several significant risk factors for each year of age from 1-9 yr. The strongest predictor of blood Pb at all ages was air Pb, but the secondary risk factors were age dependent. Household dustiness was significantly related to blood Pb in young children, especially those under 2 yr of age; soil lead may be an important source of ingested Pb for children between 2 and 7 yr. Other significant effects included that of pica at about 2 yr of age, a slight effect of the occupational category of the fathers of 5-8 yr old children, and a tendency for 8 and 9 yr old boys to have higher blood Pb than girls of the same age. Pb concentration in household paint was not a significant risk factor. These results suggest that a multifactorial approach to the prevention of excessive Pb absorption by children is required.
