Blood lead concentration measured against intellectual function in a pooled analysis of seven cohorts

Lanphear BP, Hornung R, Khoury J, et al. (2005) · Environmental Health Perspectives

The pooled analysis reported that a lifetime average blood lead increase from 2.4 to 30 µg/dL was associated with a 6.9-point decline in full-scale IQ, with the steepest decrement occurring below 10 µg/dL.

What they studied

7 international prospective cohort studies, 1,333 children followed to age 5–10

What they found

The pooled analysis reported that a lifetime average blood lead increase from 2.4 to 30 µg/dL was associated with a 6.9-point decline in full-scale IQ, with the steepest decrement occurring below 10 µg/dL.

What it does not establish
