“…Inorganic pollutants and environmental variables measured indoors and outdoors were as follows: (i) carbon monoxide (CO), (ii) carbon dioxide (CO 2 ), (iii) particles with mass median diameter ≤2.5 lm (PM 2.5 ), (iv) particles with mass median diameter ≤10 lm (PM 10 ), (v) nitrogen dioxide (NO 2 ), (vi) ozone (O 3 ), (vii) temperature, (viii) relative humidity (RH), and (ix) water vapor mixing ratio (H 2 O-MR). The methods for sampling and analysis, and the concentrations obtained, are presented in DSEWPC (2010), Lawson et al (2011), andMolloy et al (2012).

This study characterized indoor volatile organic compounds (VOCs) and investigated the effects of the dwelling characteristics, building materials, occupant activities, and environmental conditions on indoor VOC concentrations in 40 dwellings located in Melbourne, Australia, in 2008 and 2009. A total of 97 VOCs were identified. Nine VOCs, n-butane, 2-methylbutane, toluene, formaldehyde, acetaldehyde, d-limonene, ethanol, 2-propanol, and acetic acid, accounted for 68% of the sum of all VOCs. The median indoor concentrations of all VOCs were greater than those measured outdoors. The occupant density was positively associated with indoor VOC concentrations via occupant activities, including respiration and combustion. Terpenes were associated with the use of household cleaning and laundry products. A petroleum-like indoor VOC signature of alkanes and aromatics was associated with the proximity of major roads. The indoor VOC concentrations were negatively correlated (P < 0.05) with ventilation. Levels of VOCs in these Australian dwellings were lower than those from previous studies in North America and Europe, probably due to a combination of an ongoing temporal decrease in indoor VOC concentrations and the leakier nature of Australian dwellings.

“…In L3 (compact stack room), there were old wood shelves, old books and tile floor, and thus the average total concentrations and individual carbonyl levels were the lowest among the three rooms. Similarly, Molloy et al (2012) reported that elevated concentrations of formaldehyde were observed in dwellings constructed in recent decades compared to older buildings.…”

The concentrations of 18 carbonyl compounds and their health risks for people were investigated in indoor and outdoor air of three different rooms of a library in Guangzhou, South China. Indoor air samples were collected during normal activities of staff and students, and carbonyl compounds were analyzed by high-performance liquid chromatography. The results show that the total concentrations of 18 carbonyls ranged from 8.8 to 73.9 µg m -3 with a mean value of 24.7 µg m -3. Acetone was the most abundant species with a mean value of 10.8 µg m -3 in indoor air, followed by formaldehyde and acetaldehyde. The levels of carbonyls in this study were relatively lower than most of other microenvironments in the literature. The average total concentration of carbonyls in the electronic reading room was higher than those in stack room and compact stack room. Diurnal variation in carbonyl concentrations was not distinct in the three rooms. The indoor/outdoor ratios and Spearman correlation coefficients demonstrated that endogenous emission sources contributed significantly to most of indoor carbonyls, while outdoor infiltration might be one of the main sources for acetaldehyde. The personal exposure, lifetime cancer risk, and non-cancer chronic health impacts through inhalation associated with formaldehyde and acetaldehyde were estimated and discussed.

According to literature data, some of the main factors which significantly affect the quality of the indoor environment in residential households or apartments are human activities such as cooking, smoking, cleaning, and indoor exercising. The paper presents a literature overview related to air quality in everyday use spaces dedicated to specific purposes which are integral parts of residential buildings, such as kitchens, basements, and individual garages. Some aspects of air quality in large-scale car parks, as a specific type of indoor environment, are also discussed. All those areas are characterized by relatively short time use. On the other hand, high and very high concentration levels of xenobiotics can be observed, resulting in higher exposure risk. The main compounds or group of chemical compounds are presented and discussed. The main factors influencing the type and amount of chemical pollutants present in the air of such areas are indicated.
