This paper reports experimental study of air quality in the kitchen of the CSTB experimental house MARIA. These experiments are transition between measurements in an experimental cell and in situ measurements. Indeed, ventilation conditions are controlled via either a hood or via a mechanical ventilation at the exhaust. The kitchen studied is also equipped with a pan on an electric cook-top which temperature is controlled. However, unlike measurements in test cells, wall temperatures cannot be controlled. Impact of cooking vapour on indoor air quality is analyzed using a tracer gas (SF6).
324 microenvironmental measurements were carried out with identical protocols on 81 elementary teachers working in 2 cities in eastern Finland. They allowed the comparison of the personal exposure to particles and microbes with the exposure assessed by stationary samplers in home and workplace.
This paper sums up a longitudinal study carried out on a group of students and teachers in a remediated moisture-damaged school. Registration of subjective data (questionnaires) and objective data (nasal histamine reactivity) has been made. Results and discussion are presented.
The aim of that study was to test the impact of cleaning on indoor environement quality. Surface dust measurements were made on samples taken from office rooms before and after cleaning during the heating period of the buildings. Before the sampling, the occupants completed a questionnaire survey. The data were analyzed then discussed.
A 2x3 series of experimental conditions under ambient room temperature of 26 °C, two Personalised ventilation (PV) supply air temperatures of 20, 23 °C, and three levels of PV air flow rates of 4.5, 7.3, 11.2 L/s/person were conducted using tropically acc
This study surveyed concentrations of airborne AP (alkyphenols) in indoor air and outdoor air in Tokyo. An analytical method has been developed using the gas chromatography/mass spectrometry-SIM.
A recent survey study suggested that elderly people’s lifestyle and building + dwellings factors exposed them to an uncomfortable and poor environment regarding indoor air quality. In order to confirm the qualitative statements of this study, measurements
This paper presents the results of a study that explored if higher indoor minus outdoor CO2 concentrations were associated with increased student absence. The results of multivariate analyses are presented.
A summary of environmental investigations carried out from 1992 to 2002 in Italian schools in operation by the ISPESL is provided in this article. After having identified the potential sources of exposure, bulk and air samplings were performed in the suspected contaminated areas. The samplings were then collected on membrane filters. Their analysis was made by phase contrast optical microscopy and scanning electron microscopy.
That study was conducted in Nashville (TN) : during six weeks, measurements using passive ozone samplers were made on a group of school children aged 10 to 12 to estimate the outdoor/indoor /personal ozone exposure. Personal ozone exposure depends of the time spent indoors and outdoors.
