introduction reducing and optimizing energy consumption and consequently environmental pollution reductions, besides improving building performance providing occupants comfort conditions, make the building's concept closer to the concept of green building and sustainability. once the decision to build green has been made, one of the first steps in the green design process is to establish f...

Background: The COVID-19 pandemic has accelerated an already existing trend of individuals increasingly working remotely. With the growing popularity remote working, specifically in a home office, there is critical need to better understand and characterize potential environmental differences between these two spaces. Indoor air pollution can have adverse health effects impair cognitive ...

This paper presents an assessment of indoor air quality at a public bus terminal. For this purpose, air samples were collected and analyzed for the presence of carbon monoxide, particulate matter, and volatile organic compounds. Mathematical modeling was used to simulate emission factors, occupational exposure, and required ventilation rates to maintain adequate indoor air quality. Mitigation m...

Background: A common concern of the poultry industry is the presence of fungal pathogens in the birds’ environment, which may constitute a considerable health hazard to the birds, farmers, and those living in proximity of the farm. OBJECTIVES: The aims of this study were to assess the mycoflora in the indoor and outdoor environments of poultry breeding houses and studying the efficacy of disinf...

To evaluate the levels of indoor air pollution in rural areas of China and their effects on respiratory health, we monitored the indoor (bedroom and kitchen) and outdoor levels of PM10, SO2 and CO in 189 randomly selected households of rural areas, Anhui province, China. We also conducted an investigation of 487 subjects between the ages of 15 – 65 years old with a questionnaire. The PM10 level...

BACKGROUND The study of the microbial communities in the built environment is of critical importance as humans spend the majority of their time indoors. While the microorganisms in living spaces, especially those in the air, can impact health and well-being, little is known of their identity and the processes that determine their assembly. We investigated the source-sink relationships of airbor...

NO₂ and particulate matter are the air pollutants of most concern in Ireland, with possible links to the higher respiratory and cardiovascular mortality and morbidity rates found in the country compared to the rest of Europe. Currently, air quality limits in Europe only cover outdoor environments yet the quality of indoor air is an essential determinant of a person's well-being, especially sinc...

Much of the world population, particularly in developing countries, still relies on firewood to meet basic energy needs. The resulting indoor air pollution can have severe health consequences, particularly for young children who spend considerable time in close proximity to the fire while their mothers cook. In this paper we use data from a household survey to examine gas stove adoption, firewo...

The adverse effects of contaminated outdoor air have been recognized and subject to control for many years. More recently environmental engineers and health professionals have become cognizant of the hazards associated with contaminated indoor air. It is now understood that contaminated indoor air negatively impacts human health, worker productivity, and physical property. Volatile organic comp...
