in the Detroit Free Press, "High lead poisoning linked to lower test
scores in DPS" by Keith Matheny from 2/25/13, reports on research that
matches blood test results for lead in 21,000 Detroit Public School
students with those students' elementary and middle school standardized
test scores:
"Children with lead at 2 to 5 micrograms per
deciliter in their blood -- equal to or below stricter levels of concern
set by the federal Centers for Disease Control and Prevention last year
-- had a 33% higher likelihood of poor academic performance, said
Harolyn Baker, a coauthor of the study and director of epidemiology at
the nonprofit Michigan Healthcare Quality Improvement Organization.
"Students
with blood lead levels greater than 5 micrograms per deciliter have a
50% chance of doing poorly on MEAP [Michigan Educational Assessment
Program] tests, the study found."
