Abstract:
ve To explore the health impacts of air pollution on children. Methods Based on monitoring data on outdoor air pollutants of SO2, NOx, TSP and CO, The local non-specific immune function [the activity of saliva lysozyme, the content of secretory immunoglobulin A (SIgA)]and the pulmonary ventilation function [vital ca-pacity (VC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), 25%, 50% and 75% forced expiratory volume in one second (V25, V50, V75) and maximum ventilatory volume (MVV)] were determined, and the questionaire was carried out among 656 school-age children aged 7~15 yrs in industrial area (polluted area)and 712 school-age children aged 7~15 yrs in relative clean area (control area). Results Significantly higher levels of SO2, NOx , TSP in outdoor air were found in polluted area compared with those in control area ( P
