10 This study evaluates the indoor environmental quality (IEQ) in Tanzania schools as part of the Improving 11 Learning Through Classroom Experience (ILCE) Program. The objective is to assess the baseline classroom 12 IEQ that can affect students' health and academic performance, with a focus on cost-effective modifications 13 to improve learning e...

Classrooms have more students per square meter than other buildings such as offices, making them more crowded. In addition, children respire more than adults and are in contact with one another more often. For appropriate student comfort, wellbeing, and health, including reducing the risk of transferring communicable diseases (for example, COVID-19...

This study evaluated the microbial reduction efficiency of three portable air purifiers and two portable HVAC systems from different manufacturers in a classroom. Bacillus velezensis, a safe surrogate for airborne pathogens, was aerosolized in a sealed unused classroom using a jet atomizer. Each device was tested independently, with bioaerosol samp...

Crude oil spills create environmental hazards, leading to air pollution and respiratory health risks in under-five children due to their developing organs. This study compares ambient air quality (AAQ) and respiratory health (RH) of under-five children in crude oil-impacted and less-impacted communities. The study involved 450 under-five children (...

This study investigates the impact of indoor environmental quality (IEQ) on student absence rates in pre-retrofitted U.S. schools, emphasizing the importance of assessing and maintaining optimal conditions. The research analyzes data from 140 classrooms in 46 U.S. schools, incorporating parameters such as temperature, humidity, carbon dioxide, nois...

The Improving Learning through Classroom Experience (ILCE) program investigates cost-effective modifications in East African schools. Initial findings on indoor environmental quality (IEQ) are presented, establishing baseline conditions for temperature, relative humidity light, acoustics etc. The ongoing Alpha phase implements retrofit options in s...

Buildings are constructed and operated to satisfy human needs and improve quality of life. Good indoor air quality (IAQ) and thermal comfort are prerequisites for human health and well-being. For their provision, buildings often rely on heating, ventilation, and air conditioning (HVAC) systems, which may lead to higher energy consumption. This dire...

Abstract: Introduction: Under-five years old (U5) children that reside in oil spill communities are exposed to various pollutants, and therefore are prone...

The current climate emergency concerns and the COVID-19 pandemic demand urgent action to maintain healthy indoor environments in energy efficient ways. Promoting good indoor environments, in particular, increasing ventilation levels, has been a prominent strategy to mitigate the risk of COVID-19 transmission indoors. However, this strategy could be...

Background: We systematically reviewed the literature's existing knowledge on crude oil spills and the respiratory health (RH) outcomes of clean-up workers. Methods: We searched Pub-Med, Google Scholar, SCOPUS, Web of Science, and Science Direct databases to systematically review studies of crude oil spills and RH outcomes of clean-up workers publi...

Children are vulnerable to environmental stress and pollution due to their weak organ system, and they spend a substantial amount of their time in school. There is a continuous need to assess their school and classroom environmental condition to make sure that they always conform to standard. This study aims to assess the impact of different indoo...

The incidence of adverse events in healthcare is a global problem with negative consequences for all stakeholders including patients, their family members, health professionals and the government. Patient safety and patient safety culture lie at the heart of all adverse events within healthcare settings. The culture of an organization determines it...

Microorganisms, especially fungi, from damp indoor environments are known to be one of the main causes of degradation of indoor air quality and can pose serious health hazard to occupants because of the production of airborne particles. Particles produced during microbial growth include both living and non-living particles , which can be submicrome...

A total of 15 classrooms went through on‐site assessments/inspections, including measurements of temperature (T), and concentrations of carbon monoxide (CO) and carbon dioxide (CO2). In addition, the level of surface bio‐contamination/cleaning effectiveness was assessed by measuring adenosine triphosphate (ATP) levels on students’ desks. Based on t...

Many factors exist in the internal environment of building. These factors could be biological, physical, or chemical, and they determine the indoor environmental quality (IEQ) of any given building. Indoor environmental quality and indoor air quality (IAQ) are used interchangeably in certain literatures; however, there is a fundamental difference b...

This study aimed to assess the condition of elementary school buildings in Nigeria as well as the surrounding environmental condition. Five elementary schools in southwestern Nigeria went through on site assessments/inspections. Inspection data shows that the general quality of facilities in the buildings was low. For example, only one school had f...

A series of studies, including data on all elementary schools in Finland, seventy elementary schools in USA and five elementary schools in Nigeria, were conducted on school building condition, indoor environmental quality (IEQ), and students' health and learning outcomes. Building condition was assessed based on questionnaires to school principals...

There is limited research on school indoor environmental quality in developing countries. A total of 15 classrooms from five Nigerian elementary schools went through on site assessments/inspections, including measurements of indoor temperatures (T), and concentrations of carbon monoxide (CO) and carbon dioxide (CO2). In addition, the level of surfa...

This thesis evaluates the condition of elementary school buildings in Nigeria as well as indoor environmental conditions of the classrooms and their potential health effects on students. A total of 15 classrooms from five elementary schools were assessed. The conditions prevalent in the classrooms were evaluated on site and indoor/outdoor environm...

Background/aim Research on school indoor environmental quality (IEQ) are rare in developing countries due to the extremely low funding for research and student education. This study sought to evaluate IEQ in classrooms and the general condition of school buildings. Methods Five primary schools, including three classrooms per school, were assessed...

Basic elementary school is compulsory for students in most countries of the world. Therefore, children spend a considerable amount of their time in school studying. Subsequently, exposure to substances in their school indoor environment can affect their studies and health. In addition, children are more susceptible to indoor pollutants because thei...

Background: The aim of this paper was to examine associations between school building characteristics, indoor environmental quality (IEQ), and health responses using questionnaire data from both school principals and students. Methods: From 334 randomly sampled schools, 4248 sixth grade students from 297 schools participated in a questionnaire....

The aims were to assess indoor environmental quality (IEQ) in Finnish elementary school buildings, and to study associations between ventilation rate and student health and learning outcomes. The study population consisted of about one thousand sixth grade students from 59 schools in southern Finland. Students’ learning outcomes were assessed based...
