Analysis of pulmonary function of children close to a large chemical industrial park / 上海预防医学

ABSTRACT

Objective To investigate pulmonary function of the children close to a large chemical industrial park and its influencing factors . Methods Date of daily average air PM10 ,SO2 and NO2 levels from two communities ( Area A near a chemical industrial area , area B far away from the chemical industrial area ) of Shanghai were collected .Questionnaires and pulmonary functions tests were performed among children of grade 3 to 5 in two primary schools from the two communities . Results The annual PM10 levels were 75.12 μg/m3 in area A and 79.46 μg/m3 in area B, which were both slightly higher than the secondary standard of Ambient Air Quality Standard, GB 3095-2012 ( 70 μg/m3 ) .The annual NO 2 level (40.67μg/m3)in area B was slightly higher than the secondary standard of Ambient Air Quality Standard, GB 3095-2012(40 μg/m3).There were no significant differences in PM10, SO2 and NO2 levels between the two communities .The height and some pulmonary functions parameters such as forced vital capacity ( FVC) and forced expiratory volume in one second ( FEV1 ) of children in are A were lower than those in area B.After reference predicted values of lung function were balanced , there were no significant differences in children's pulmonary function parameters between the two areas , FVC% and FEV1% were both above 87%, FEF50% and FEF75% were both above 72%.Bad condition of the ventilation in the kitchen and passive smoking had adverse effects on FEV 1%or FVC%and FEF50%%(r about -0.1). Conclusion The air quality close to the large chemical industrial park was not so bad , and there is no significant differences in the children's pulmonary function between area A and area B .The children's pulmonary may be more sensitive to the indoor environment in the low levels of atmosphere pollution .
