摘要
对南京市大气中臭氧(O_3)的污染状况及人体接触健康效应进行调查。结果表明,南京市各功能区大气中 O_3浓度范围从未检出到0.069mg/m^3。臭氧灯室、紫外灯室 O_3浓度分别为1.289mg/m^3和0.245mg/m^3,复印机室 O_3浓度在0.01～0.03mg/m^3之间.O_3接触组主观症状的出现率明显高于对照组。O_3接触组肺功能指标 FVC、MMEF、V_(75)、V_(5(?))、V_(25)明显低于对照组。
This paper reports the results on O_3 pollution in air at Nanjing and health effects in population.O_3 concentration from nil to 0.069mg/m^3 in all functional regions in Nanjing.O_3 concentration is 1.289 mg/m^3 in ozone lamp rooms,0.245 mg/m^3 in ultraviolet lamp rooms,0.01～0.03mg/m^3 in photocopying machine rooms.Incidence rates of the symptoms in O_3 exposure group is higher than control.Regarding the lung functions of FVC,MMEF, _(75),_(50),_(25) the O_3 exposure group is lower than control.
