The purpose of the present study was to analyze the relationship between the levels of air pollutants and respiratory function/physical efficiency of pre-adolescent children living in the Upper Silesian Industrial Region.
Spirometric evaluations and physical exercise test were performed in 103 children aged 14-16. Standard spirometry was used to analyze: vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and maximal voluntary volume (MVV). From 1994 through 2008, air pollutants were regularly monitored, and compared with reference ranges.
Differences were noted in the average annual pollutant (SO2, NO2, PM10, CO) concentrations during the observation period. Exposure to air pollution was associated with reduced respiratory function and may lead to a decline in physical efficiency in pre-adolescent children.
The pollution-related reduction of lung function in childhood might be related, at least partially, to long-term exposure to particulate air pollutants, and especially in those children who spend more time practicing outdoor sports.
本研究旨在分析上西里西亚工业区居住的青春期前儿童的空气污染物水平与呼吸功能/身体效率之间的关系。
对 103 名 14-16 岁的儿童进行了肺量计评估和体育锻炼测试。标准肺量计用于分析：肺活量（VC）、用力肺活量（FVC）、一秒用力呼气量（FEV1）和最大自主通气量（MVV）。1994 年至 2008 年，定期监测空气污染物，并与参考范围进行比较。
在观察期间，注意到平均年度污染物（SO2、NO2、PM10、CO）浓度存在差异。暴露于空气污染与呼吸功能降低有关，并可能导致青春期前儿童身体效率下降。
儿童时期与污染有关的肺功能下降至少部分可能与长期接触颗粒物空气污染物有关，尤其是在那些花更多时间进行户外体育活动的儿童中。
