Influence of indoor microenvironments and personal activities on the inhalation dose and personal exposure to PM2.5, PAH, OXY-PAH, VOC and BC air pollutants

[摘要] There is growing public awareness regarding the risk associated with poor indoor air quality (Ward, Underberg et al. 2009)and indoors like in the homeand workplace (Bernstein, Alexis et al. 2008). The aim of the study is to measure the magnitude of concentration in indoor environments, and personal levels of some air pollutants such as volatile organic compounds, PM2 s, polycyclic aromatic hydrocarbons,oxy-PAHs and Black carbon. Estimate the mass of BC that might be in the breathing zone and the lung dose. To conduct the personal exposure and home and workplace measurements,45 healthy,non-smokingadult volunteer subjects were recruited. Concentration of the compounds might vary across volunteer's activities, thereforethe importance of having personal exposure data which might be more representative. To accurately assess the human exposure and the human risk associates with the air pollution. New or recently remodeled building were found to have high concentration of VOC, therefore, a decay time should be considered before to move into a new buildings.BC particle size concentrations need to be investigate deeply as few information is available. Moreover not information about BC deposited dose was found.
