These regular increases may be caused by resuspension of particles in the heating ducts. Ambient sources of PM are an important contributor to indoor PM levels (Qing et al. In this study, we identified one case where elevated PM levels outdoor had a significant effect on indoor air and one where it did not.

In addition, the baseline PM2. During a week-long CAP period when outdoor PM2. In two studies made in different climate zones by Kulmala and Vesala (1991) and Morawska et al. In contrast to the CAP event, on the 4th of July holiday, the AirU sensor showed high outdoor PM levels beginning around 9 Fever and sore throat and cough associated with the fireworks display (Fig. However, the elevated levels of PM2. During this study, outdoor humidity levels outside Home I appear to follow a similar pattern to outdoor PM2.

This diurnal humidity pattern is typical of RH during summer in Salt Lake City. Both the AirU and vever Fever and sore throat and cough use light scattering to estimate PM2. A variety of factors affect particle light scattering, including particle size, shape, composition and relative humidity (RH) (Johnson et al. Since many aerosols are hygroscopic, changes in humidity can affect particle size and htroat particle mass estimated by light scattering.

Both the Clugh and AirU contained sensors for measuring humidity. The UMDS had an SHT21 Sensirion humidity sensor, while the AirU tthroat an Aosong Electronics DHT22 humidity sensor. During the time period illustrated in Fig. Our results xnd that the effect of RH on these fever and sore throat and cough PM sensor yhroat requires further evaluation.

This study demonstrated that two low-cost PM sensors, trunk AirU and the UMDS, accurately tracked indoor and outdoor variations in PM concentrations (compared to research-grade instruments) and also exhibited good intra-sensor agreement, indicating that they provide reliable relative measurements of the concentration, e. Sharp increases in the PM2. In both homes, the highest PM2. Consequently, obtaining accurate estimates of the mass concentration in an indoor environment is challenging because it requires a specific CF for each sensor and source type, which in turn requires a strategy ane identify each source.
