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...

Saving energy and improving Indoor Air Quality (IAQ) and thermal comfort in buildings are traditionally competing goals. Facilities that manage one of these objectives well tend to compromise the other. Building Automation Systems (BAS) have been limited in their ability to sense these characteristics of a building and therefore cannot act on them. A majority of buildings define IAQ in terms of...

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...

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, ...
