摘　　要：目的探讨室内外空气污染源对室内空气NO2浓度的影响。方法使用ML9841B型化学荧光连续监测仪对英国WestCumbria郡Whitehaven镇中心2户家庭室内外空气NO2浓度的动态变化进行连续监测。结果Whitehaven镇中心大气NO2浓度背景值为19～28μg/m3(10min均值),早晚交通高峰时段为38～47μg/m3(10min均值),使用燃气灶具后厨房空气中NO2浓度约增加190μg/m3(10min均值),小时均值高达253mg/m3,超过英国国家大气质量策略标准[200μg/m3(小时均值)]。结论室内使用燃气灶具产生的NO2对室内空气质量的影响远远大于室外空气的影响。Objective To explore the influences of indoor and outdoor sources of air pollutants on NO 2 concentra tions in indoor air.Methods The dynamic variations of NO 2 concentrations in indoor and outdoor air were continuously monitered by ML 9841B chemiluminescence continuous monitoring analyzer in2families of White haven town of west Cumbrra,UK.Results During the period of indoor air monitoring,typical background concentrations of NO 2 in air in the center of White haven were between19and28μg /m 3 (10min-mean),and rose to38-47μg /m 3 (10min-mean)during the morning and evening rush of traffic.NO 2 concentration increased about 190μg /m 3 (10min-mean)after the use of a gas cooker in the kitchen A1-hour mean concentration of253μg /m 3 was recorded in the kitchen air of one of the houses,which substantially exceeded the NAQS standard of200μg /m 3 .Conclusion The increase of NO 2 concentration in kitchen air induced by the use of gas appliances played a more important role in influencing the indoor air quality than outdoor air did.
