What are the Health Implications for Children in Schools Near Traffic?


Association between Traffic-Related Air Pollution in Schools and Cognitive Development in Primary School Children: A Prospective Cohort Study (24 age pdf, Jordi Sunyer, Mikel Esnaola, Mar Alvarez-Pedrerol, Joan Forns, Ioar Rivas, Mònica López-Vicente, Elisabet Suades-González, Maria Foraster, Raquel Garcia-Esteban, Xavier Basaga, Mar Viana, Marta Cirach, Teresa Moreno, Andrés Alastuey, Núria Sebastian-Galles, Mark Nieuwenhuijsen, Xavier Querol, PLoS Med, Mar. 3, 2015)

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).
