It is divided into four parts that the project implementation status and results of each chapter are described as follows:
This study is aimed to integrate the database of indoor air indicators and pollutants established by our research team over the past 15 years to evaluate indoor activities, outdoor activities and usage behavior impacts on indoor air quality (IAQ) in Taiwan. Since 1998, we have continuously collected monitoring data of IAQ in a total of 764 buildings in different indoor environments. We further integrated the profiles of ambient pollutants from EPA atmospheric stations according to the sampling area and specific time. Building characteristics and potential indoor and outdoor sources were summarized as well. We used descriptive statistics, correlation analysis, Kruskal-Wallis test and Generalized Estimating Equations (GEE) to evaluate the impacts of indoor activities, outdoor activities and usage behavior on IAQ. The deterioration of IAQ would make people have headaches, respiratory infections, asthma, allergies, poor attention and sick building syndrome by literature review. Therefore, we still need to pay attention to IAQ in different types of places. After the data analysis, we found that all of the spaces flow/configuration and environment, indoor equipment or furniture, types and environment maintenance of air conditioner and potential sources from indoor or outdoor would affect IAQ, but the affected air pollutants and influence degree of impact factors are inconsistent in different types of places. In conclusion, our study is the first to evidence a series of impacts of ambient pollutants and climate variations on indoor air pollutants by using a 15-years dataset of field investigations. We have clarified the indoor activities, outdoor activities and usage behavior contributing to the change of levels of indoor air pollutants in different places.
This study has also conducted a comparison between data of non-standard sampling methods and standard sampling method for PM2.5 and PM10. We suggest that build the relationship between the levels of PM2.5 and PM10 personal environment monitoring (PEM) instrument and standard sampling methods, PM2.5 and PM10 PEM instrument could be used to monitor the levels of PM2.5 in the fields. According to these results of compositions of indoor PM2.5, meta-analysis and risk assessment, this study found: (1) Al, Ca, Mg, Fe and K, SO4-2 and organic carbon are predominant compositions of indoor PM2.5, (2) soil and photochemical reactions are important contributors of indoor PM2.5 and (3) it needs more evidences in the correlation between indoor carbon level and health effects in the future, to assess whether set indoor carbon standard values.
In this study, indoor semi-volatile compounds (including PAEs and PAHs) partitioning between the gas, particle (PM2.5 and PM10) and settled dust were investigated in ten public places (7 cram schools and 3 theaters). Results showed that the levels of gaseous PAHs were higher than that for particulate PAHs in all sampling sites. Gaseous PAHs were dominated by naphthalene, which exists almost entirely in the gas phase. The average air concentrations (gas- and particle phase) of naphthalene in cram schools and movie theaters were 336383 ng/m3 and 8941333 ng/m3, respectively. Two- and three-ring PAHs accounted for most of the air PAHs in cram schools and theaters, while PAHs in the dust samples were dominated by two- to four-ring PAHs. Lower molecular weight PAEs such as DEP, DIBP and DBP were frequently detected in the gas phase, while the PAEs with molecular weight between 300 to 400 g/ mol. were more abundant in the particle phase.
