According to a 1990 New England Journal
of Medicine, “The persistence toxicity of lead was seen
to result in significant and serious impairment of academic
success, specifically a seven fold increase in failure to graduate
from high school, lower class standing, greater absenteeism,
impairment of reading skills sufficiently extensive to be labeled
reading disability (indicated by scores two grades below the
expected scores), and deficits in vocabulary, fine motor skills,
reaction time and hand-eye coordination.”
