An ozone (O3) exposure study was conducted in Nashville, TN, using passive O3 samplers to measure six weekly outdoor, indoor, and personal O3 exposure estimates for a group of 10- to 12-yr-old elementary school children. Thirty-six children from two Nashville area communities (Inglewood and Hendersonville) participated in the O3 sampling program, and 99 children provided additional time-activity information by telephone interview. By design, this study coincided with the 1994 Nashville/Middle Tennessee Ozone Study conducted by the Southern Oxidants Study, which provided enhanced continuous ambient O3 monitoring across the Nashville area. Passive sampling estimated weekly average outdoor O3 concentrations from 0.011 to 0.O30 ppm in the urban Inglewood community and from 0.015 to 0.042 ppm in suburban Hendersonville. The maximum 1- and 8-hr ambient concentrations encountered at the Hendersonville continuous monitor exceeded the levels of the 1- and 8-hr metrics for the O3 National Ambient Air Quality Standard. Weekly average personal O3 exposures ranged from 0.0013 to 0.0064 ppm (7-31% of outdoor levels). Personal O3 exposures reflected the proportional amount of time spent in indoor and outdoor environments. Air-conditioned homes displayed very low indoor O3 concentrations, and homes using open windows and fans for ventilation displayed much higher concentrations.
在田纳西州纳什维尔进行了一项臭氧（O₃）暴露研究，使用被动式O₃采样器对一组10至12岁的小学生进行每周六次的室外、室内和个人O₃暴露估计测量。来自纳什维尔地区两个社区（英格伍德和亨德森维尔）的36名儿童参与了O₃采样项目，99名儿童通过电话访谈提供了额外的时间活动信息。按照设计，这项研究与南方氧化剂研究组织在1994年进行的纳什维尔/田纳西州中部臭氧研究同时进行，该研究在纳什维尔地区提供了强化的连续环境O₃监测。被动采样估计，城市英格伍德社区每周平均室外O₃浓度为0.011至0.030 ppm，郊区亨德森维尔为0.015至0.042 ppm。在亨德森维尔连续监测点遇到的1小时和8小时环境浓度最大值超过了O₃国家环境空气质量标准的1小时和8小时指标水平。每周平均个人O₃暴露范围为0.0013至0.0064 ppm（室外水平的7 - 31%）。个人O₃暴露反映了在室内和室外环境中花费的时间比例。使用空调的家庭室内O₃浓度非常低，而使用开窗和风扇通风的家庭浓度则高得多。
