“…Aspiration hood or general ventilation decreased significantly concentrations levels [44]. Concentrations of formaldehyde measured in our study are in accordance with those reported from the study of Lü et al [12]. However, concentrations reported from the study of Ghasemkhani et al [8] were 10 times higher.…”

BackgroundWe aimed to assess, for the first time, the nature of the indoor air contamination of hospitals.Methods and FindingsMore than 40 volatile organic compounds (VOCs) including aliphatic, aromatic and halogenated hydrocarbons, aldehydes, alcohols, ketones, ethers and terpenes were measured in a teaching hospital in France, from sampling in six sampling sites – reception hall, patient room, nursing care, post-anesthesia care unit, parasitology-mycology laboratory and flexible endoscope disinfection unit – in the morning and in the afternoon, during three consecutive days. Our results showed that the main compounds found in indoor air were alcohols (arithmetic means ± SD: 928±958 µg/m3 and 47.9±52.2 µg/m3 for ethanol and isopropanol, respectively), ethers (75.6±157 µg/m3 for ether) and ketones (22.6±20.6 µg/m3 for acetone). Concentrations levels of aromatic and halogenated hydrocarbons, ketones, aldehydes and limonene were widely variable between sampling sites, due to building age and type of products used according to health activities conducted in each site. A high temporal variability was observed in concentrations of alcohols, probably due to the intensive use of alcohol-based hand rubs in all sites. Qualitative analysis of air samples led to the identification of other compounds, including siloxanes (hexamethyldisiloxane, octamethyltrisiloxane, decamethylcyclopentasiloxane), anesthetic gases (sevoflurane, desflurane), aliphatic hydrocarbons (butane), esters (ethylacetate), terpenes (camphor, α-bisabolol), aldehydes (benzaldehyde) and organic acids (benzoic acid) depending on sites.ConclusionFor all compounds, concentrations measured were lower than concentrations known to be harmful in humans. However, results showed that indoor air of sampling locations contains a complex mixture of VOCs. Further multicenter studies are required to compare these results. A full understanding of the exposure of healthcare workers and patients to complex mixtures of chemical compounds can then be related to potential health outcomes.

“…In a newly constructed hospital, TVOC concentrations were higher than 400 µg/m 3 , in nearly half of the patients rooms studied [10]. Some studies have reported the presence of other compounds including acetone, acetaldehyde, 2-butanone [11], [12], 2-phenoxyethanol, butoxyethanol, hexanal and nonanal [13].…”

“…A comparison of indoor BTEX concentrations among various cities around the world is shown in Table 4. BTEX pollutions in spring hotels were at the middle level among the reported sites, higher than offices and primary schools, and lower than a photocopy shop, drugstore, schoolroom, hospital, hotel and hotel guest rooms [1][2][3]12,15,32,33]. The difference in pollutants levels between hot spring hotel rooms and previously reported rooms was due to the decoration and furniture materials used in the room, and high toluene levels were found in Hotel 1 in southern China due to the usage of poor quality carpet fitted in the room [12,15,33].…”

Abstract:In Guangdong province, many hot springs were exploited and developed into popular places for tourist. In addition, hotels have been set up near hot spring sites to attract people, including local citizens, to spend their spare time inside these so-called "spring hotels". In our study, indoor air quality was investigated in four hot spring hotels in Guangdong province, China. Measured indoor pollutants included CO 2 , CO, PM 10 , PM 2.5 and Volatile Organic Compounds (VOCs). As the result show, high concentrations of carbon dioxide might be attributed to poor ventilation; and the variations of indoor PM 10 , PM 2.5 concentrations were related to occupants' activities. Alpha-pinene and toluene were the most common VOC species in the hot spring hotels other than monocyclic aromatic hydrocarbons like Benzene, Toluene, Ethylbenzene and Xylenes (BTEX), which were at medium levels among the reported indoor pollutants. High cancer risk of benzene in the newly decorated rooms should be seriously taken into consideration in the future. Indoor to Outdoor air concentration ratios (I/O) for CO 2 and VOCs were higher than 1, indicating their strong indoor sources. Negative correlations were found between indoor CO 2 and all the other compounds, and VOCs were shown to be significantly correlated (p < 0.01) to each other, including aromatic hydrocarbons and mono-terpenes. For indoor and outdoor air compounds, correlation coefficients among all compounds did not show a significant correlation, which indicated that these pollutants had different sources. Principal components analysis by SPSS showed that indoor materials, inhabitants' activities and respiration, cleaning products and outdoor sources were the main sources of indoor detected pollutants in hot spring hotels.

“…Some studies have reported the carbonyl levels of indoor air. For example, the total concentrations of 19 carbonyls in hospitals of Guangzhou, China, were between 18 and 106 µg m ) (Lü et al, 2010b), and those in subway stations of Shanghai varied from 28.8 to 124 µg m -3 (Feng et al, 2010). The total concentrations of 12 carbonyls in an academic building of Beijing ranged from 20.7 to 166 µg m -3 (Jiang and Zhang, 2012).…”

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.
