Improvements in air pollution are leading to brighter, smarter toddlers, according to a new study from Columbia University in New York.
For more than two decades, Prof Frederica Perera and a team from the Columbia Center for Children’s Environmental Health measured the air pollution exposure of pregnant women and the development of their children in the disadvantaged communities of northern Manhattan and the South Bronx. More than 1,100 children were assessed when they were one, two and three years old.
