The aim of the present study was to present the association between short-term elemental carbon exposure and lung function in schoolchildren from Mexico City.<\/jats:p><jats:p>55 asthmatic and 40 non-asthmatic children were followed for an average of 22 weeks. A spirometry test was performed every 15 days during follow-up. Portable air samplers collected particulate matter onto Teflon filters.
