本文对生活在铅污染历史悠久地区的312名年龄在2.5-16岁之间的男女进行了生物统计学研究。目的是寻找10个生物测量变量与这些儿童体内铅吸收指标(即血液中铅的量)之间的最终关系。生物统计学变量的标准化值在高PBB和低PBB类别中通过多变量方差分析进行比较。比较10个生物计量变量的向量，发现两类多溴联苯水平之间存在显著差异。我们发现一些证据表明，年龄较小的儿童(8岁以下)比年龄较大的儿童更有可能吸收体内的铅，并且更容易受到亚临床铅中毒的影响。在年龄较小的儿童中，两种PBB类别的生物统计学变量的平均值之间的差异一直更大(尽管不是很明显)。这一趋势在老年人群中消失了。这些结果证实了文献中的数据，即幼儿处于特别危险的境地。可以得出的结论是，铅吸收对儿童的生物特征有微妙但显著的影响，这种影响可能在8岁以下的儿童中更为重要。
This paper deals with a biometric study of 312 boys and girls, aged 2.5-16 years, living in an area with a long history of pollution by lead. The aim was to search for eventual relationships between ten biometric variables and measures of lead absorption in the bodies, i.e. the amount of lead in the blood (PbB), of these children. Standardized values of the biometric variables were compared in the high-PbB and low-PbB categories, by multivariate analysis of variance. Comparison of the vectors of the ten biometric variables reveals a significant difference between the two categories of PbB levels. We found some evidence that the younger children (below 8 years of age) are more likely to absorb lead in the body and are more vulnerable to the effects of subclinical lead intoxication than their older counterparts. The differences between the averages of biometric variables in the two PbB categories are consistently (although not significantly) greater among younger children. This trend disappeared in the older age group. These results confirm data from the literature that young children are especially at risk. It can be concluded that there is a subtle, but significant, influence of lead absorption on the biometric profiles of children and that this effect is probably more important in children below 8 years of age.
