Multiple-Factor Analysis on Air Pollution, Part of Immune and Pulmonary Ventilation Function in Children / 环境与健康杂志

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
