since individuals spend the majority of their times indoors, fine particles generated in indoor combustion processes and by resuspension are important for health effects assessment. the nature and magnitude of indoor particle exposures can change rapidly because of the rapid changes in activities and sources. indoor pm 2.5 concentrations were measured in indoor office, café, and home where peop...
Indoor environmental conditions (thermal, noise, light, and indoor air quality) may affect workers' comfort, and consequently their health and well-being, as well as their productivity. This study aimed to assess the relations between perceived indoor environment and occupants' comfort, and to examine the modifying effects of both personal and building characteristics. Within the framework of t...
This study was conducted in metalwork and woodwork industries in Jeddah Industrial Estate. The purpose of this study was to assess the magnitude of industrial noise exposure and to propose remedial actions. Noise was measured at different times of a day in 28 randomly selected factories and workshops. Results indicated that noise levels varied according to the type and size of a factory, and th...
This study examines characteristics of atmospheric methylsiloxane pollution in indoor settings where interior renovation/redecoration is being undertaken, in addition to ordinary family homes and inside family cars. Concentrations of atmospheric methylsiloxane in these locations were approximately one order of magnitude higher than that in outdoor areas. The average indoor concentration of meth...
MODELLING ENVIRONMENTAL EQUITY: EXPOSURE TO ENVIRONMENTAL URBAN NOISE POLLUTION IN BIRMINGHAM, UK by
This paper examines the extent to which inequalities in noise exposure are present in the city of Birmingham in the English midlands. Estimates of road and rail noise levels were made using established sound propagation models and were combined with data on noise generated from the city’s airport. Demographic details from the 1991 UK Census provided information on population age, ethic makeup, ...
UNLABELLED Indoor air pollutants are a potential cause of building related symptoms and can be reduced by increasing ventilation rates. Indoor carbon dioxide (CO(2)) concentration is an approximate surrogate for concentrations of occupant-generated pollutants and for ventilation rate per occupant. Using the US EPA 100 office-building BASE Study dataset, we conducted multivariate logistic regres...
AIMS To examine the relation between the psychosocial work environment and the perceived indoor air problems measured by a questionnaire survey; and to discuss the role of a questionnaire as a means to enhance collaboration in the challenging multiprofessional process of solving indoor air problems. METHODS The research material comprises surveys conducted in 1996-99 in 122 office workplaces ...
