“…Thermal-optical transmittance is the most powerful instrumental technique for EC/OC determination, which has been also successfully applied in indoor environments [1,4]. Moreover, ion chromatography (IC) has also proved to be suitable for determination of major inorganic ions in PM 2.5 samples collected in offices [10].…”

“…In the past decade, the number of chemical studies aiming at understanding the adverse effects of exposure to atmospheric particulate matter (PM) with an aerodynamic diameter smaller than 2.5 μm (PM 2.5 ) on human health at workplaces has increased substantially [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15], since people living in urban areas spend more than 90% of their time indoors [16]. Only some of these reports have, however, dealt with indoor air quality in offices located in mechanically ventilated buildings [1,3,4,[11][12][13][14].…”

“…The most commonly used instrumental analytical techniques for multi-elemental determination in PM 2.5 samples are either inductively coupled plasma atomic emission spectrometry (ICP-AES) or inductively coupled plasma mass spectrometry (ICP-MS) [28,39], as well as instrumental neutron activation analysis [38], proton-induced X-ray emission (PIXE) [14,40,41] and energy dispersive X-ray fluorescence spectrometry [3,5,10]. The methodological limitations of the aforementioned techniques have been recently compiled [42].…”

“…office buildings [146] and school buildings [147] indicated that indoor activities are the main contributor of indoor PM levels. However, there are sufficient evidences demonstrating that outdoor pollutants can easily penetrate into its nearby indoor environment through flow exchanges [146,148e151].…”

a b s t r a c tMany buildings in urban areas are more or less naturally ventilated. A good understanding of the current status and issues of indoor environmental quality (IEQ) in naturally ventilated urban buildings and the association with urban microclimate is fundamental for improving their IEQ. This paper reviews past studies on (a) the microclimate in urban street canyons, (b) the potential influence of such microclimate on IEQ of nearby naturally ventilated buildings, and (c) the real-life IEQ status in these buildings. The review focuses mainly on studies conducted by on-site measurements. The microclimate in urban street canyons is characterized by low wind speed, high surface temperature difference, high pollutant concentration, and high noise level. Insufficient ventilation rates and excessive penetration of outdoor pollutants are two key risks involved in naturally ventilated urban buildings. Existing knowledge suggests that reasonable urban planning and careful building envelope design are the primary methods to ensure acceptable IEQ and maximize the utilization of natural ventilation. However, quantitative studies of both microclimate in street canyons and IEQ in buildings are still highly insufficient in many aspects, which make cross comparison and influencing factors analysis currently impossible. Based on the limitations of previous studies and the current issues of naturally ventilated urban buildings, suggestions are made for future studies to better understand and improve IEQ in naturally ventilated urban buildings.

“…Repeated or prolonged exposure to high levels of formaldehyde concentration in the indoor environment can result in serious respiratory diseases, eye irritation, headache, asthma, as well as in degenerative, inflammatory and hyperplastic changes of the nasal mucosa (Lim et al, 2011). Long-term inhalation of formaldehyde in the indoor environment has also been identified as an important source of Sick Building Syndrome (SBS) (Horemans et al, 2010;Nakaoka et al, 2014;Mentese et al, 2015). Consequently, formaldehyde is an important indicator of indoor air quality (IAQ) and as such has attracted wide scale public attention (Raw et al, 2004;Liu et al, 2008;Allen et al, 2016).…”

This study focused on measuring the concentration of formaldehyde in furniture markets, malls, hotels, and restaurants in Guilin, Liuzhou, and Nanning in Guangxi, China. Correlations between the indoor formaldehyde concentration and temperature, humidity, and air change rate were also obtained. The sixty sampled public places selected for this study represented the typical public indoor environment in Guangxi. The percentages of measured formaldehyde concentrations exceeding the standard (0.1 mg m -3 ) in furniture markets, malls, and hotels were 94%, 87%, and 20%, respectively. The highest concentrations measured in furniture markets, malls, hotels, and restaurants were 0.313 mg m ). This work shows that wood-related decorations and merchandise that contain high levels of formaldehyde are the major sources of formaldehyde pollution in indoor environments. Further analysis demonstrates that strong correlations (r > 0.80, p < 0.01) exist between the indoor formaldehyde concentration and temperature, humidity, and air change rate, which indicate that these environmental factors appear to be additional key reasons for the high levels of indoor formaldehyde pollution. The results show that a decrease in temperature and humidity or an increase in air change can effectively alleviate the level of indoor formaldehyde pollution. The findings of this study further promote the development of measures to control indoor air pollution.
