“…This has resulted in an increased likelihood of chemical compounds being retained indoors and, in turn, increased air contamination. Various chemical compounds are emitted into indoor spaces by a wide range of sources, including building and indoor materials, furniture, curtains, air fresheners, deodorants, pesticides, personal care products, cooking, and other everyday household products [10,17,18].…”

“…For atopic dermatitis, relocation to or repair of a new house increased both diagnostic and therapeutic prevalence. This could have been caused by building materials and adhesives, which are sources of volatile organic compound emissions, particularly in newly built houses [18,21]. However, a history of atopic dermatitis in siblings and more time spent at school significantly decreased the risk of atopic dermatitis.…”

We examined the effect of long-term changes in environmental factors on the prevalence of allergic diseases in elementary school students in Ulsan, Korea. This longitudinal study was conducted among 390 students who were enrolled from three elementary schools in Ulsan in both the first (2009–2010) and second survey (2013–2014). The International Study of Asthma and Allergies in Childhood questionnaire was used to determine the prevalence of allergic diseases and hazardous environmental factors. Generalized estimating equations (GEE) were used to investigate the impact of environmental factors on the change in the prevalence of allergic diseases. The survey revealed that an increased risk of allergic rhinitis was associated with exposure to secondhand smoke, the remodeling of a room, the replacement of wallpaper or flooring, the use of a humidifier, and irritation symptoms of air pollution. Atopic dermatitis was associated with the relocation to or repairs of a new house, and allergic conjunctivitis was associated with low levels of weekly physical activity, the use of insecticides, and irritation symptoms of air pollution. The results indicate that (1) allergic rhinitis and atopic dermatitis are associated with indoor pollution, (2) allergic conjunctivitis is associated with exposure to indoor chemical compounds and low levels of weekly physical activity. This study suggested that the proper evaluation and decrease in the number of environmental risk factors could effectively manage allergic diseases.

“…In previous studies, it has been reported that almost no guidance or explanation from the construction company is received on SBS prevention [70]. This survey also found that the contractor was unaware of the improvement plan or the degree of effectiveness (Table 12).…”

According to UAE Health Ministry and Dubai Healthcare City reports, 15% of Dubai residents have a chronic respiratory disease such as asthma. Moreover, 90% of the 150,000 patients at Al Ain Hospital suffered from upper respiratory tract respiratory diseases, bronchitis, or asthma. Sick Building Syndrome (SBS) has emerged as a social problem in the United Arab Emirates (UAE). The Dubai Municipality regulates Indoor Air Quality (IAQ) with strict stipulations before moving in, but they are relatively passive about regulations related to healthy living. This paper aims to explore the actual state of perception of the IAQ from townhouse residents in Dubai, UAE. The characteristics of the resident’s perceptions of the IAQ are identified, and the influential factors affecting residents’ perceptions of IAQ are extracted. As a methodology, the survey was conducted on four townhouse projects in Dubai from December 2021 to January 2022. A total of 114 copies were distributed, and 98 documents were used. Analysis of the survey data was processed using IBM SPSS Statistics 26.0. The results showed a statistically significant correlation between the cognitive and anxiety levels of SBS with the presence or absence of experience. It was statistically confirmed that the most influential factors were the age of the children and the occupancy time of housewives and children. This is because of the perception that wives who spend a relatively long time in the house and their young children are exposed to indoor air pollution for a long period of time and are easily affected by this influence on the concerns about young children about SBS. Ninety-five percent of the respondents answered that they knew more than average about SBS, indicating a very high level of awareness. As for the degree of anxiety, 87.0% of the respondents felt higher levels of anxiety than usual. However, most of them did not know or were indifferent to the understanding of the air quality improvement methods. The awareness of actual contents was lower than that of residents who assessed that they knew about SBS.

“…This distinction is important in the context of the standards used to benchmark the safety and acceptability of IAQ in educational buildings. Numerous longitudinal studies have shown that TVOC concentrations display a strong temporal dependency following the completion of new and renovated buildings (Holøs et al, 2019;Persson et al, 2019;Suzuki et al, 2019). Mysen et al (2003) and Wachenfeldt et al (2007) proposed that for buildings such as schools and offices indoor air pollution could be successfully controlled using demand-controlled mechanical ventilation.…”

Young people spend extended periods of time in educational buildings, yet relatively little is known about the air quality in such spaces, or the long-term risks which contaminant exposure places on their health and development. Although standards exist in many countries in relation to indoor air quality in educational buildings, they are rarely subject to detailed post-occupancy evaluation. In this study a novel indoor air quality testing methodology is proposed and demonstrated in the context of assessing the post-occupancy performance of a recently refurbished architecture studio building at Loughborough University, United Kingdom. The approach used provides a monitoring process that was designed to evaluate air quality in accordance with United Kingdom national guidelines (Building Bulletin 101) and international (WELL Building) standards. Additional, scenario-based, testing was incorporated to isolate the presence and source of harmful volatile organic compounds, which were measured using diffusive sampling methods involving analysis by thermal desorption - gas chromatography - mass spectrometry techniques. The findings show that whilst the case-study building appears to perform well in respect to existing national and international standards, these guidelines only assess average CO2 concentrations and total volatile organic compound limits. The results indicate that existing standards, designed to protect the health and wellbeing of students, are likely to be masking potentially serious indoor air quality problems. The presence of numerous harmful VOCs found in this study indicates that an urgent revaluation of educational building procurement and air quality monitoring guidelines is needed.
