In the CleanSky 2 ComAir study, subject tests were conducted in Fraunhofer Flight Test Facility cabin mock-up. This mock-up consists of front section a former in-service A310 hosting up to 80 passengers. 12 sessions outdoor/recirculation airflow ratio was altered from today’s typically applied fractions 88% recirculation fraction. leads increased relative humidity, carbon dioxide (CO2) and Tota...

Indoor air pollutant sources are crucial in assessing IAQ, especially when outdoor concentrations low. In the present study, PM mass a range of five sizes; CO, CO2, O3, NO, NO2, and TVOC concentrations; along with temperature relative humidity were monitored three indoor locations university. The monitoring took place building dedicated to teaching undergraduates. first two locations, professor...

BACKGROUND The present study is an attempt to explore the association between kitchen indoor air pollutants and physiological profiles in kitchen workers with microalbuminuria (MAU) in north India (Lucknow) and south India (Coimbatore). METHODS The subjects comprised 145 control subjects, 233 kitchen workers from north India and 186 kitchen workers from south India. Information related to the...

This study was done to investigate the relationship between Indoor Air Quality (IAQ) and prevalence of Sick Building Syndrome (SBS) in two different offices (old and new) in Selangor. Hundred and seventy workers were selected consist of 85 office workers for each building. Questionnaire based on Indoor Air Quality and Work Symptoms Survey, NIOSH, Indoor Environmental Quality Survey, 1991 was us...

To assess the robustness of various indoor air quality (IAQ) indices, we explored the possible role of reproducibility-induced variability in the measurements of different pollutants under similar sampling and emissions conditions. Polluted indoor conditions were generated by pan frying fish samples in a closed room. A total of 11 experiments were carried out to measure a list of key variables ...

Emissions of volatile organic compounds (VOCs) and carbonyls from three types of commercially available wallpapers (i.e., PVC-coated, paper-backed, natural material-coated) in Korea were evaluated using a 20 L small chamber. A total of 332 products were tested for emission factors, frequencies of occurrence and composition ratios. Toluene and formaldehyde concentrations were below Korean standa...

Indoor air quality (IAQ) has a substantial impact on public health. Since the beginning of COVID-19 pandemic, more employees have worked remotely from home to minimize in-person contacts. This pilot study aims measure difference in workplace IAQ before and during pandemic its employees’ The levels fine particulate matter (PM2.5) total volatile organic chemicals (tVOC) were measured offices at h...

BACKGROUND A growing body of epidemiologic evidence suggests an association between exposure to cleaning products with asthma and other respiratory disorders. Thus far, these studies have conducted only limited quantitative exposure assessments. Exposures from cleaning products are difficult to measure because they are complex mixtures of chemicals with a range of physicochemical properties, th...
