“…Concerning NO 2 , average concentrations were approximately five times higher than the maximum levels obtained by Rodriguez et al, 2022 [ 24 ] in Spain. Maximum concentrations measured for TVOCs in classroom 2 were two times higher than the maximum concentration detected in university classrooms in South Africa and in university libraries in Turkey [ 25 , 37 ].…”

A comprehensive study assessed indoor air quality parameters, focusing on relevant air pollutants such as particulate matter (PM10 and PM2.5), gaseous compounds (CO, CO2, formaldehyde, NO2) and volatile/semi-volatile organic chemicals, as well as respiratory viruses (including SARS-CoV-2), fungi and bacteria in Spanish university classrooms. Non-target screening strategies evaluated the presence of organic pollutants inside and outside the classrooms. Saliva samples from teachers and students were collected to explore correlations between respiratory viruses in the air and biological samples. Indoor results revealed the punctual exceedance of recommended guidelines for CO2, formaldehyde (HCHO), volatile organic compounds (TVOCs) and PM in the least naturally ventilated classrooms. Significant differences occurred between the classes, with the least ventilated one showing higher average concentrations of CO2, HCHO, NO2, PM10 and PM2.5. A respiratory virus (rhinovirus/enterovirus) was detected in the medium naturally ventilated classroom, although saliva samples tested negative. Suspect screening tentatively identified 65 substances indoors and over 200 outdoors, with approximately half reporting a high toxicological risk based on the Cramer rules. The study provides a comprehensive overview of indoor air quality, respiratory viruses and organic pollutants in university classrooms, highlighting the variations and potential health risks associated with ventilation differences.

“…According to the literature, only a few studies on IAQ in university environments worldwide have been published [ 5 , 23 , 24 , 25 ], and there is a lack of harmonisation in the way IAQ has been assessed. Overall, only CO 2 has been regularly measured as a proxy indicator of IAQ.…”

“…Furthermore, the HQ of male technicians was 1.39‐fold greater than that of female technicians, implying that male technicians were at a higher risk of developing non‐carcinogenic health outcomes. Güneş et al 89 investigated indoor air quality in library universities and found a HQ less than one for students and library staff when using the USEPA equation. In this study, only the HQ for students was less than one when using the USEPA equation.…”

“…The difference in the results might be partly explained by the different methodological approaches. The authors 89 used the limit values for indoor PM 2.5 prescribed by the World Health Organization as the RfC, whereas in this study, the RfC for diesel particulates was used to calculate the RfC for PM 2.5 .…”

Exposure to indoor PM 2.5 is associated with allergies, eye and skin irritation, lung cancer, and cardiopulmonary diseases. To control indoor PM 2.5 and protect the health of occupants, exposure and health studies are necessary. In this study, exposure to PM 2.5 released in an academic metallurgy workshop was assessed and a health risk assessment was conducted for male and female students and technicians.Polycarbonate membrane filters and an active pump operating at a flow rate of 2.5 L/ min were used to collect PM 2.5 from Monday to Friday for 3 months (August-October 2020) from 08:00-16:00. PM 2.5 mass concentrations were obtained gravimetrically, and the Multiple-Path Particle Dosimetry model was used to predict the deposition, retention, and clearance of PM 2.5 in the respiratory tract system. The risk of developing carcinogenic and non-carcinogenic effects among students and technicians was determined. The average PM 2.5 mass concentration for August was 32.6 μg/m 3 32.8 μg/m 3 for September, and 32.2 μg/m 3 for October. The head region accounted for the highest deposition fraction (49.02%), followed by the pulmonary (35.75%) and tracheobronchial regions (15.26%). Approximately 0.55 mg of PM 2.5 was still retained in the alveolar region 7 days after exposure. The HQ for male and female students was <1 while that of male and female technicians was >1, suggesting that technicians are at risk of developing non-carcinogenic health effects compared with students.The results showed a risk of developing carcinogenic health effects among male and female technicians (>1 × 10 −5 ); however, there was no excess cancer risk for students (<1 × 10 −6 ). This study highlights the importance of exposure and health studies in academic micro-environments such as metallurgy workshops which are often less researched, and exposure is underestimated. The results also indicated the need to implement control measures to protect the health of the occupants and ensure that the workshop rules are adhered to.

“…The investigation of IAQ in Turkey suggested that due to natural ventilation, the IAQ of libraries is influenced by many parameters related to both indoor and outdoor environments. Therefore, mechanical ventilation is more effective for controlling IAQ [23]. Modeling for airborne fungal concentration indicated that indoor environmental parameters such as %RH and PM 2.5 and potential confounders were associated with fungal concentrations in university library rooms [24].…”

Since people spend most of their time (80-90%) in indoor environments, it is necessary for public, commercial, and private buildings to achieve high indoor air quality (IAQ) and comfort levels [1]. IAQ has a substantial influence on human health and well-being. Prolonged exposure to indoor pollutants can result in building-related illnesses such as respiratory illness, cardiovascular lung disease, and sick building syndrome [2][3][4][5]. Moreover, poor IAQ also impacts on performance and productivity [6,7]. A study showed that it can decrease office productivity by 6-9%. A cause of lower performance possibly comes from common symptoms
