A new study suggests reducing the children’s lead exposure in Massachusetts have helped them do better in school, Jasmine Garsd of NPR News reported. Jessica Wolpaw Reyes, an Amherst College associate professor of economics, has been researching on the effects of lead since the 1990s. Her interest on the metal started when she was a graduate student at Harvard and was pregnant with her first child.
“Lead is a very useful metal, which is kind of how we got in this situation,” said Reyes, who lived in a lead-rich house.
“Throughout history people keep using lead despite the fact that it has these neurotoxic effects,” she added. The effects of lead in kids could lead to lower IQ and behavioral problems.
The study, published in the Harvard Educational Review, also found that schools with a larger decline in lead showed greater improvements in test scores. Reyes said the “unsatisfactory performance” in the state would have been 5 percent higher if lead usage remained at 1990 levels.
And “because the Childhood Lead Poisoning Prevention Program reduced children’s lead when they were very young,” she added, “those children performed substantially better when they were in elementary school.”
The report also showed 2 percent of children who would have been failing are now doing well because of the state’s lead policy. Read more
