Size-dependent PM10 indoor/outdoor/personal relationships for a wind-induced naturally ventilated airspace

Indoor Air Quality and Prevalence of Sick Building Syndrome Among Office Workers in Two Different Offices in Selangor

“…From the result, it showed that office workers who worked in the areas with PM 2.5 concentration above 53.88 µg m −3 have the tendency to develop the sick building syndrome 7.2 times likely compared to those who worked in the office environment with level of PM 2.5 below than 53.88 µgm . Studies showed that PM 10 for indoor and outdoor air for a wind-induced natural ventilated airspace depended strongly on the ambient particles' distribution and the design of the building openings (Liao et al, 2003) and study conducted by Schwartz and Dockery (1996) stated that particles less than 10 micron and 2.5 micron from any origin can worsen human's heart and induce breathing problem especially to the susceptible group. It was supported by Riediker et al (2004) who stated that it has been reported that exposure to PM 10 and PM 2.5 can cause cardiovascular implications on healthy young office workers in North Carolina, US.…”

“…Particulate matters in the air would be influenced by various factors such as wind-speed, air temperature and relative humidity, atmospheric stability and others (Sham, 1987). In addition, studies showed that PM 10 for indoor and outdoor air for a wind-induced natural ventilated airspace depended strongly on the ambient particles' distribution and the design of the building openings (Liao et al, 2003).…”

Assessing hazardous risks of human exposure to temple airborne polycyclic aromatic hydrocarbons

“…d Eq. (4) is the general matrix form of presenting HRT model [21][22][23] where the PAHs and the PEFs used in the calculation associated with the cancer evidence of individual PAH compound classified by Nisbet and LaGoy [18] and Malcom and Dobson [19].…”

“…Followed by the principle of mass balance, the dynamic equations of inspiratory oral cavity varying with particle size range k and time t to each regional compartment are given a by a state-space realization form of a linear dynamic representation ( Table 2, Eq. (4)) [22,23]. The reference values for anatomical and physiological parameters, including volumes, breathing rates, transfer coefficients, and clearance rate, are taken from the ICRP66 [21].…”

“…The reference values for anatomical and physiological parameters, including volumes, breathing rates, transfer coefficients, and clearance rate, are taken from the ICRP66 [21]. More details for HRT model developments and constructions have been described in elsewhere [22,23].…”
