(Byers & Lord, 1943;Marlowe, 1995;David et al, 1976; The negative correlation between blood lead and SAT trends is consistent with research demonstrating an inverse relationship between preschool blood lead and IQ, and research showing IQ is an excellent predictor of academic achievement.

Psychological dysfunctions in lead-exposed workers: Relation to biological parameters of exposure. Scand. j. work environ. & health 4 (1978) 295-303. Insidious neurotoxic effects of lead have been studied in a popoulation of 42 lead-exposed workers and a reference group of 22 comparable workers with no lead exposure. The age of the individuals ranged from 18 to 50 years. The complete Wechler Adult Intelligence Scale, as well as psychomotor and memory tests, was included in the test battery. The exposure was assessed by means of the lead concentration in blood and hair and the ratio between zinc protoporphyrin and hemoglobin in the blood. Significant differences were found between the two groups of workers, especially concerning long-term memory, verbal and visuos:gatia1 abstraction, and psychomotor speed. Decreased performance in these tests was in most cases associated with indices of increased lead exposure, not only in the total population studied, but also within the lead-exposed group alone. Blood lead and zinc protoporphyrin appeared to correlate better with the intellectual impairment than did hair lead, and thus these analyses are probably better predictors for neurotoxic effects of lead. Age and exposure time were not found to be significant confounding factors in this study.

“…In the 1940s it was recognized by astute physicians that children who had been treated for lead poisoning suffered permanent neurologic damage (13). They reported poor school performance, impulsive behavior, short attention span, restlessness, and occasional neurological signs in these children.…”
