Air Pollution Delays Cognitive Development in Children

The brains of young children are in danger as Spanish researchers confirm that neurotoxicants in polluted air can cross the blood-brain barrier to cause inflammation and delay brain maturation.

The study, led by Dr. Jordi Sunyer of the University of Barcelona, measured three aspects of memory and attentiveness in about 2715 primary school children every 3 months for a year and found an 11.4 percent increase in the working memory of children in clean-air schools, in contrast to only 7.4 percent increase in children at the highly polluted schools. 

With these results, schools located in remote areas with clean air prove safer than schools close to high traffic areas and the attendant pollution from exhaust fumes. Hence, air pollution and schools' locations should be carefully regulated.
