Today we review research into the impact on brain development of children at schools exposed to high and low pollution levels produced by traffic emissions in Barcelona, Spain. Results indicate that students in low pollution areas have almost twice the increase in working memory (11.5%) per year compared to children in high pollution areas (7.4%). This is a warning to urban planners concerning the locations of schools: locate them at least 500 m from heavy traffic or take responsibility for the health impacts to the young children who attend these schools. Unfortunately many cities have schools located on major roads with traffic (in Ottawa, for example, more than 50% of day-cares (and 20% of schools) are located within 50 m of heavy traffic).
