Finally, once all of the children turned four years old, the researchers tested their full-scale intelligence quotient (FSIQ) using the Weschler Preschool and Primary Scale of Intelligence.
The tests revealed that the children who were exposed to air filters while in utero scored 2.8 points higher with their FSIQ.
“These results, combined with evidence from previous studies, strongly implicate air pollution as a threat to brain development,” said Ryan Allen, a professor of environmental health at the university.
But, while the air filters proved somewhat successful in combatting air pollution’s developmental effects, Allen believes they are not enough.
“Air pollution is everywhere, and it is preventing children from reaching their full potential. Air cleaners may provide some protection. But, ultimately, the only way to protect all children is to reduce emissions,” Allen explained.
