A strong statistical correlation was found among the monthly averages of lead concentrations in umbilical cord blood (about 500 births/month), indoor air (12 sites/month), and gasoline lead sales between March, 1980 and April, 1981 in Boston. Tap water lead (24/month) variations did not correlate with blood lead in this population.
1980年3月至1981年4月期间,在波士顿,人们发现脐带血中铅浓度的月平均值(约每月500例分娩)、室内空气(每月12个监测点)和汽油铅销售量之间存在很强的统计相关性。该人群中自来水铅含量(每月24次检测)的变化与血铅水平并无关联。
