Special Issue Information

Dear Colleagues,

We are pleased to announce the third edition of this Special Issue. According to the World Health Organization, ambient air pollution is a major global public health concern. High levels of pollution in the air may cause diseases and have health repercussions in the long or short term, such as stroke, heart diseases, lung cancer, and both chronic and acute respiratory diseases. Indoor and ambient air pollution have been recognised as one of the main risk factors for non-communicable diseases, alongside unhealthy diets, tobacco smoking, harmful use of alcohol, and physical inactivity. Most outdoor air pollutants penetrate into our homes, workplace, and schools and can react with indoor air pollutants. In fact, the concentrations of harmful air pollutants can be higher in indoor than in outdoor spaces. Moreover, people spend most of their time (over 90%) indoors. This evidence shows the importance of studying the exposure to indoor air pollution (including chemicals and bioaerosols), which is a very important health risk factor that needs to be controlled and reduced.

Therefore, we encourage scholars to submit their manuscripts for publication in the second edition of this Special Issue.

Air pollution from particulate matter 2.5 (PM2.5) may negatively impact students’ learning due to its neurotoxic effects. Therefore, we ask: What is the effect of PM2.5 air pollution on the academic performance of Chilean eighth-grade students? Objective: To compare the academic performance of eighth-grade students living in the three most PM2.5-polluted areas of Chile with those living in the three least polluted areas. Additionally, we compared the academic performance of schools in the most and least polluted areas according to their administrative dependency. Methodology: Academic performance was assessed using the results of the 2019 SIMCE test (mathematics, and language score). The most and least polluted areas were determined based on the three-year average PM2.5 levels reported by the Chilean Ministry of the Environment. Results: The mathematics and language scores were lower in schools located in areas with higher pollution PM2.5 with a small effect size. When analyzing the scores by administrative dependency, students from subsidized schools in highly polluted areas obtained lower scores in all tests compared to those in less polluted areas, a pattern not observed in private or municipal schools. Conclusion: These findings suggest that PM2.5 pollution alone may not fully explain variations in academic performance, highlighting the need to explore additional contributing factors. Full article

This study evaluates indoor environmental quality (IEQ) in childcare facilities, focusing on air quality and lighting—key factors affecting children’s health and development. The analysis examines a nursery in Seville, Spain, where continuous monitoring revealed challenges in maintaining suitable indoor conditions. Carbon dioxide (CO2) levels often surpassed Spanish standards (770 ppm) and stricter thresholds (550 ppm) for sensitive groups, peaking at nearly 1900 ppm. These concentrations are linked to possible cognitive impairments and increased airborne pathogen risks, with Attack Rates (ARs) exceeding 70%. Passive ventilation strategies, such as window openings, proved insufficient, emphasizing the need for Controlled Mechanical Ventilation (CMV) systems to ensure consistent air renewal while maintaining thermal comfort. Lighting assessments identified insufficient circadian stimulus during key periods. Excessive lighting during nap times disrupted rest, while morning daylight levels failed to provide adequate circadian stimulation. These findings stress the importance of integrating solar protection and dynamic daylight and electric lighting systems to align with children’s biological rhythms. This research highlights the urgent need for comprehensive IEQ strategies in childcare settings, combining advanced ventilation, hygrothermal management, and circadian-friendly lighting to create safer and healthier environments for young children.

The paper presents a number of tests of the carbon monoxide concentration in a single-car garage equipped with exhaust ventilation, while the combustion engine of a parked passenger car is operating. The main source of carbon monoxide in the garage is the internal combustion engine of a passenger car. Single-car garages are characterized by a relatively small volume, which causes a rapid accumulation of carbon monoxide inside the garage. The aim of this publication is to present the results of research on carbon monoxide concentration in a single-family building garage with the combustion engine in a passenger car running and at various air exchanges in the garage. The test results showed that the permissible values (WHO, NAAQS) of carbon monoxide concentrations were significantly exceeded, both with the exhaust ventilation switched on and off. The highest carbon monoxide concentration values (2253 ppm) in the garage were observed when the exhaust ventilation was turned off. The study also developed two one-dimensional models of carbon monoxide concentrations in a garage with the combustion engine of a passenger car turned on, with the exhaust ventilation turned on and off. The models developed can be used in ventilation design to estimate the carbon monoxide concentrations in garages, based on the type of car and the number of air changes. Full article
