摘要

An academic-community partnership is currently working on an intervention study (Home Air in Agriculture Pediatric Intervention - HAPI) to examine the effectiveness of High Efficiency Particulate Air (HEPA) cleaners to improve children health with asthma in a rural agricultural setting. We measured particulate matter (PM) concentrations (PM2.5, PM10) in indoor air before and after the implementation of the HEPA cleaners in the homes. We selected the RTI International MicroPEM (MP) samplers for measuring PM2.5 and PM10 concentrations due to their low subject burden (size/noise), low relative cost, and ease of use by community partners for field sampling (calibration/operational procedures). Implementing the MP samplers, originally personal monitors, into stationary monitors in low income homes with children, many with limited space presented practical challenges. We developed a low cost, readily mobile and "child proof" minimal profile sampler stand utilizing an intravenous pole with hooks that held a bird suet feeder. The MPs were placed inside the feeder. The stand provided an opportunity to hang other passive samplers (Ogawa) used in the study. Sporadic incomplete PM sampling by the MPs during our 2 week integrated sampling period were investigated through subject and field staff interviews and iSocket 3G power outage monitoring. We discerned child contact with on/off buttons and unplugging the devices explained most data loss. Simply placing lab tape over MP buttons and additional training for families has resulted in more complete sampling. Preliminary data from subjects with sampling conducted before and after HEPA air cleaner assignment demonstrate effectiveness in PM for intervention homes (% change) compared with control homes (%).
