Forced vital capacity (FVC) of children in the age group 10–12 years are reported as a function of quantum increase in PM2.5 level in ambient air. The data are reported for the children in the categories based on their respective body mass index (BMI). FVC (% predicted) values decreased with increasing level of PM2.5. The subjects are found to respond in a selective manner as plateau was observed for FVC values against some selected ranges of PM2.5 concentration levels (74 µgm−3 to >117 µgm−3). To explain this unusual behavior, sac theory is proposed which explains the observations of FVC for subjects of all categories with different BMI values.

细颗粒质量水平升高对儿童强迫肺活量下降的明显抵抗:一种生理现象
据报道,年龄在10至12岁之间的儿童的强制肺活量(FVC)与周围空气中PM 2.5含量的量子增加有关。根据儿童各自的体重指数(BMI)报告类别中儿童的数据。FVC(预测的百分比)值随着PM 2.5含量的增加而降低。发现受试者表现出选择性的反应,因为观察到针对某些选定范围的PM 2.5浓度水平(74 µgm -3至> 117 µgm -3)的FVC值处于平稳状态。为了解释这种异常行为,提出了sac理论,该理论解释了FVC对于具有不同BMI值的所有类别的受试者的观察结果。
