目的将新型颗粒计数仪 (Dylos DC1700) 的响应与常用于在遇到二手烟 (SHS) 的环境中测量 PM2.5 的设备 (TSI Sidepak 个人气溶胶监测仪 AM510) 产生的响应进行比较。方法通过燃烧香烟不同的时间段并同时运行两个设备，进行不同 SHS 浓度的受控室实验。结果 Dylos 和 Sidepak 设备对 SHS 浓度变化产生相似的响应1000克/米(3)。利用 13 个室实验的 591 分钟同时测量结果，建立了一个方程，可将 Dylos 的颗粒数浓度数据转换为 SHS 气溶胶的估计质量浓度数据。 结论 Dylos DC1700 可以提供实时数据，这些数据可转换为烟雾环境中 SHS 水平的估计值。鉴于成本低、噪音低且使用简单，该设备可能成为干预措施的有用工具，提供二手烟浓度反馈，以帮助激励家庭吸烟行为的改变。
ObjectiveTo compare the response of a new particle counting instrument (Dylos DC1700) with that produced by a device (TSI Sidepak Personal Aerosol Monitor AM510) commonly used to measure PM2.5 in settings where secondhand smoke (SHS) is encountered.MethodsControlled chamber experiments with different SHS concentrations were generated by burning a cigarette for varying time periods and running both devices simultaneously.ResultsThe Dylos and Sidepak devices produced similar responses to changes in SHS concentrations up to 1000g/m(3). Using 591min of contemporaneous measurements from 13 chamber experiments, an equation was developed to allow conversion of particle number concentration data from the Dylos to estimated mass concentration data for SHS aerosol.ConclusionsThe Dylos DC1700 can provide real-time data that may be converted to an estimate of SHS levels in smoky environments. Given the low cost, low noise and simplicity of use, this device is likely to be a useful tool for interventions to provide feedback of SHS concentrations to help motivate changes in smoking behaviour at home.
