Abstract
The air we breathe both indoors and in the external environment significantly affects human health and life. The legal systems across the globe, including the United Nations programs, have taken measures to protect the right to clean air as a basic human right. Urbanization and modern lifestyles have changed the dynamics of need and usage of products and allied activities. However, the scope of this study is focused on the investigation of indoor air quality (IAQ). This study is perhaps the first ever attempt to investigate the indoor air pollutant in different environmental setup based on building code specially for nonindustrial indoor environments, i.e., office buildings, public buildings (schools, hospitals, theatres, restaurants), and private dwellings in Dehradun, India. Air pollutants measured in this study include particulate matter (PM10), carbon dioxide (CO2), carbon monoxide (CO), ozone (O3), sulfur dioxide (SO2), nitrogen dioxide (NO2), volatile organic compounds (VOCs), and formaldehyde (HCHO). In order to identify the exposure level of indoor air pollutants on human health, chronic daily intake has been calculated. In residential building occupancies, the concentration of particulates is higher in indoor air, and the key sources are kitchen activities such as the operation of gas stoves for cooking. In educational buildings, significant pollutants present are CO2, formaldehyde, and respirable suspended particulate matter (RSPM), predominantly due to characteristic available ventilation systems. Compared to other indoor occupancies, institutional buildings related to health science have significant sources of indoor pollutants generated from biomedical waste, medical equipment, and instruments.
期刊介绍：
Air Quality, Atmosphere, and Health is a multidisciplinary journal which, by its very name, illustrates the broad range of work it publishes and which focuses on atmospheric consequences of human activities and their implications for human and ecological health.
It offers research papers, critical literature reviews and commentaries, as well as special issues devoted to topical subjects or themes.
International in scope, the journal presents papers that inform and stimulate a global readership, as the topic addressed are global in their import. Consequently, we do not encourage submission of papers involving local data that relate to local problems. Unless they demonstrate wide applicability, these are better submitted to national or regional journals.
Air Quality, Atmosphere & Health addresses such topics as acid precipitation; airborne particulate matter; air quality monitoring and management; exposure assessment; risk assessment; indoor air quality; atmospheric chemistry; atmospheric modeling and prediction; air pollution climatology; climate change and air quality; air pollution measurement; atmospheric impact assessment; forest-fire emissions; atmospheric science; greenhouse gases; health and ecological effects; clean air technology; regional and global change and satellite measurements.
This journal benefits a diverse audience of researchers, public health officials and policy makers addressing problems that call for solutions based in evidence from atmospheric and exposure assessment scientists, epidemiologists, and risk assessors. Publication in the journal affords the opportunity to reach beyond defined disciplinary niches to this broader readership.
