对小学生室内外空气污染量和健康状况进行监测，计算出使用不同燃料家庭中小学生的NO2，SO2和CO的时间加权接触量及患病率。结果表明燃煤户学生SO2和CO的时间加权接触量分别为69．2和7903h，比燃气户学生的接触量37．9和4135h高45．2％和47.7％。燃煤户学生的呼吸系统疾患率也显著高于燃气户学生。与全国其他城市研究结果一致。
Monitoring indoor and outdoor air pollution and health status of primary school students to calculate the time-weighted exposure and prevalence of NO2, SO2 and CO of primary and secondary school students using different fuel families. The results show that the time-weighted exposures of SO2 and CO to coal-burning households are 69.2 and 7903h, respectively, which are 45.2% and 47.7% higher than that of gas households’ exposure of 37.9 and 4135h respectively. Residents of coal-fired households have significantly higher rates of respiratory disorders than gas households. Consistent with the findings of other cities in China.
