“…On the contrary, considerably fewer studies have focused on PM levels in offices (Gemenetzis, 2006;Saraga et al, 2010), despite the fact that they are one of the most common workplaces in a great many countries, where lots of people spend a considerable part of their working day. As a consequence, indoor air quality in offices is of key importance, and is essential, from a health assessment point of view, when drawing up a detailed characterization of the most dangerous compounds present in the PM of offices.…”

To date, few studies have focused on PM air quality in offices, despite the fact that a lot of people spend\ud many working hours a day in such offices. The aim of the present study is to investigate PM1 and PM2.5\ud in offices in Milan (Northern Italy) and in the air outside those offices. The PM samples were analyzed to\ud determine the entity of certain compounds with possible direct or indirect adverse effects on human\ud health: PAHs, BpA, and water soluble inorganic ions.\ud A good correlation between outdoor and indoor PM mass concentrations emerged (R2 w0.87). The\ud maximum I/O concentration ratiowas 0.92, suggesting that the indoor PM levelwas always lower than the\ud outdoor level. The average infiltration factor, FINF,was 0.55, showing that about a half of the outdoor PMhad\ud come indoors. The indoor-generated particles, Cig, had values ranging from 0 to 4.4 mg m3 (<25% of the\ud indoor PM), showing that PM indoor sources had only made a limited contribution to total indoor PM.\ud The results of the indoor-to-outdoor comparisons for the aforementioned chemical compounds\ud demonstrate that the offices were characterized by the absence of effective indoor sources of particulatebound\ud PAHs and inorganic ions, whereas Cig was around 58% of the indoor concentration for BpA. Our\ud analysis of the FINF data pointed to the presence of a volatilization effect from PM for semi-volatile\ud compounds like ammonium nitrate and 4- or 5-ring PAHs, which affected the measurement of their\ud FINF. We propose the introduction of a new and simple parameter, called volatilization correction, to take\ud account of this effect

“…Although PM 10 (PM with aerodynamic diameter Ͻ10 m) has been shown to have significant pertinence to lung disorders and respiratory and cardiovascular diseases, PM 2.5 (PM with aerodynamic diameter Ͻ2.5 m) is strongly associated with deaths, cardiopulmonary diseases, and lung cancer. 4 It was a common belief that particle size is the most important parameter responsible for these health effects, because it is the most influential factor that determines the place of particle deposition in the respiratory tract; the smaller the particles the deeper the penetration. Therefore, recent attention has been focused on PM 2.5 .…”

Because polycyclic aromatic hydrocarbons (PAHs) have been proven to be toxic, mutagenic, and/or carcinogenic, there is widespread interest in analyzing and evaluating exposure to PAHs in atmospheric environments influenced by different emission sources. Because traffic emissions are one of the biggest sources of fine particles, more information on carcinogenic PAHs associated with fine particles needs to be provided. Aiming to further understand the impact of traffic particulate matter (PM) on human health, this study evaluated the influence of traffic on PM 10 (PM with aerodynamic diameter Ͻ10 m) and PM 2.5 (PM with aerodynamic diameter Ͻ2.5 m), considering their concentrations and compositions in carcinogenic PAHs. Samples were collected at one site influenced by traffic emissions and at one reference site using lowvolume samplers. Analysis of PAHs was performed by microwave-assisted extraction combined with liquid chromatography (MAE-LC); 17 PAHs, including 9 carcinogenic ones, were quantified. At the site influenced by traffic emissions, PM 10 and PM 2.5 concentrations were, respectively, 380 and 390% higher than at the background site. When influenced by traffic emissions, the total concentration of nine carcinogenic compounds (naphthalene, chrysene, benzo(a)anthracene, benzo(b) fluoranthene, benzo(k)fluoranthene, benzo(a)pyrene, dibenzo(a,h)anthracene, indeno(1,2,3-cd)pyrene, and dibenzo(a,l)pyrene) was increased by 2400 and 3000% in PM 10 and PM 2.5 , respectively; these nine carcinogenic compounds represented 68 and 74% of total PAHs (⌺ PAHs ) for PM 10 and PM 2.5 , respectively. All PAHs, including the carcinogenic compounds, were mainly present in fine particles. Considering the strong influence of these fine particles on human health, these conclusions are relevant for the development of strategies to protect public health.

“…Noticeably low values resulted from the most extensive examination in 100 buildings with air conditioning systems in the USA (Burton et al, 2000). By contrast, particularly high concentrations were observed in Greek offices (Gemenetzis et al, 2006). These are attributed to the high outdoor air concentrations and the presence of smokers.…”
