研究表明家庭烹调燃煤使室内SO_2、CO浓度大大增加,燃煤气使NO_2浓度大大增加。燃煤者呼吸系统症状出现率及HbCO均高于燃气者(P<0.05)。燃煤与燃气者肺功能均有下降,但燃煤者反映上呼吸道功能的指标下降更甚,燃气者反映深部呼吸道功能的指标下降更甚。结果提示烹调燃煤对人呼吸系统是一危险因素,但亦不能忽视燃煤气对人小气道的损伤。
The research shows that domestic cooking coal makes indoor SO 2 and CO concentration increase greatly, and combustion gas makes NO 2 concentration increase greatly. The incidence of respiratory symptoms and HbCO of coal-fired persons were higher than those of gas (P <0.05). Pulmonary function of coal-fired and gas-fired persons both decreased, but indicators reflecting the upper respiratory tract function of coal-fired persons even worsened, while those of gas-fired persons showed a more significant drop in indicators of deep respiratory function. The results suggest that cooking coal on the human respiratory system is a risk factor, but also can not ignore the combustion gas on human small airway damage.
