The National Aeronautics and Space Administration’s (NASA) technical developments for highly reliable life support systems aim to maximize the viability of long duration deep space missions. Among the life support system functions, airborne particulate matter filtration is a significant driver of launch mass because of the large geometry required to provide adequate filtration performance and b...

Compared to conventional cage systems for laying hens, aviary housing systems generally have much higher concentrations of airborne dust and bacteria due to generation of bioaerosols by the hens from their litter access. Hence solutions to reduce these health-degrading agents are required to safeguard the indoor environment in such systems. Spraying slightly acidic electrolyzed water (SAEW) has...

Title of Document: SOURCE DEPENDENT VARIATION IN HYDROXYL RADICAL PRODUCTION BY AIRBORNE PARTICULATE MATTER AND THE IMPACT ON BEAS-2B AND JB6 CELLS. Marjan Alaghmand, Doctor of Philosophy, 2007 Directed By: Professor Neil V. Blough, Department of Chemistry and Biochemistry Numerous studies have shown an association between increased levels of particulate matter (PM) and the exacerbation of lung...

Background Air quality monitoring in brick kilns indicates very high concentrations of airborne particulate matter. Air pollution from brick kilns poses an enhanced threat to the environment and to human health. Objective To evaluate airborne particulate matter concentration and health status of brick kiln workers. Method A cross-sectional comparative study was conducted in the Kathmandu valley...

People spend most of their time inside buildings and the indoor microbiome is a major part of our everyday environment. It affects humans' wellbeing and therefore its composition is important for use in inferring human health impacts. It is still not well understood how environmental conditions affect indoor microbial communities. Existing studies have mostly focussed on the local (e.g., buildi...

BACKGROUND Chronic particulate matter (PM) exposure is correlated to various health effects, even at low amounts. WHO has defined PM concentration limits as daily and annual mean values which were made legally binding in the European Union. While many studies have focused on PM concentrations in special environments, little is known about the average PM- exposure for both employees and passenge...

Studies of air pollution and human health have evolved from descriptive studies of the early phenomena of large increases in adverse health effects following extreme air pollution episodes to time-series analyses based on the use of sophisticated regression models. In fact, advanced statistical methods are necessary to address the challenges inherent in the detection of a relatively small pollu...
