Abstract

Indoor air pollution is a major issue that impacts the quality of the air we breathe in our homes, schools, businesses, and other indoor spaces. This review paper examines the classification, sources, occurrence, health consequences, mitigation measures, and future directions of indoor air contaminants in depth. Indoor air pollutants are classified as biological pollutants, chemical pollutants, particulate matter, and combustion by-products. Each category thoroughly examines specific contaminants and their potential health effects. Building materials, home goods, combustion processes, cigarette smoke, and HVAC (heating, ventilation, and air conditioning) systems are all sources of indoor air pollution. Understanding these sources is critical for putting appropriate mitigation methods in place. Indoor air pollution must be addressed through mitigation and preventative techniques. Key tactics include ventilation and air exchange, air filtration and purification systems, source control and removal, regulation and policy initiatives, and education and awareness campaigns. These actions are intended to lower pollution levels, improve indoor air quality, and safeguard human health. Given the high health hazards and economic burden associated with poor indoor air quality, the need to tackle indoor air pollution is underlined. Vulnerable populations and the economic cost of illnesses caused by indoor air pollution are highlighted. Indoor air pollution must be addressed through mitigation and preventative techniques. Furthermore, future research areas and requirements are suggested, such as advances in monitoring techniques, understanding long-term health impacts, and raising education and awareness. This in-depth examination underlines the significance of tackling indoor air pollution to promote healthier indoor settings. © 2024 Elsevier B.V., All rights reserved.
