Examines the most important sources of indoor air pollution in dwellings. These include pollutants introduced with the outside air, pollutants generated by human activity, emissions from building materials, furnishings, cleaning and polishing materials and disinfectants. Notes the importance of keeping formaldehyde and carbon dioxide down to safe levels. Discusses the consequences for the minimum room air change rate.
Describes the different types of monitoring and sampling techniques that can determine the radiation burden of the general public from radon and its decay products. This is accomplished by measuring the range and distribution of radon and rad
Simulation methods and test results are presented here to confirm projections of actual total suspended particulate (TSP) concentration levels for representative office buildings, with particular emphasis on the 0.3 to 5 micron particulate si
The U.S. EPA initiated an indoor air monitoring program in 1982, concentrating on commercial or public-access buildings (homes for the elderly, schools, and office buildings). Several buildings from each category are sampled over 2-3 day peri
Describes methods of predicting concentration levels of indoor air pollution in a variety of residences by using residence air infiltration rates, residence volumes, and source terms, and by making assumptions about occupant lifestyle and poll
During the last fifteen years Urea-Formaldehyde (UF) bonded particle board, medium density fiberboard and plywood have replaced whole wood as a construction material for flooring, wall panelling cabinet work and furniture. At the same time,
The use of urea formaldehyde resins in Canadian houses, the mechanism of formaldehyde releases, health effects, toxicity, carginogenicity, allergic reactions and standards for ventilation are discussed.
Results of air quality measurements are presented for a group of low-leakage houses located in Saskatoon, Saskatchewan. A total of 46 houses were tested for formaldehyde, nitrogen dioxide, radon, and humidity levels. The median level of formalde
In response to employee complaints of upper respiratory and eye irritation, formaldehyde air sampling studies were conducted in two different office environments. The first was in a series of temporary modular buildings with construction simi
A microprocessor-controlled, five point, all-teflon sequential air sampling system interfaced to a continuous formaldehyde analyser, the CEA model TGM 555 Air Monitor which uses the pararosaniline colorimetric method was used tomeasure the seaso
