Analysis of five papers given at the Symposium on Sick Buildings. Conclusions are that the cause of sick building syndrome must be psychosocial, physical, chemical or biological. Symptoms are different from symptoms of mass psychogenic illne
Summary of conference discussions on formaldehyde, including character- ization, sources, measurement techniques, health effects, mitigation techniques and conclusions: 1. Elevated formaldehyde concentrations, higher than 100 ppb, are measured in many indoor environments. Formaldehyde concentrations relate positively with temperature and decrease with the age of the source. 2. Urea formaldehyde bonded products can be improved to such a degree that indoor levels can be reduced to ambient levels if the materials are properly installed and used. 3.
Contains further papers, reports and conference summaries from the 3rd International Conference on Indoor Air Quality and Climate, 1984, as well as afull list of authors and titles of papers printed in this and the previous volumes.
The recommended limits for formaldehyde in indoor air are 0.1 ppm (0.12mgm-3). There are several ways of measuring the formaldehyde concentration, including sampling tubes. Describes a newly-developed sampling tube measurement technique capable of detecting formaldehyde concentrations from 0.04 to 2.5ppm.
Draughtproofing the windows and external doors of UK dwellings can be an effective and relatively inexpensive means of comfort and reducing heat loss by natural ventilation. In most situations, draughtproofing is unlikely tocause any deterioration in the quality of indoor air. There are however a number of simple checks which should be made prior to installation to ensure that the ventilation requirements of the dwelling and its occupants are satisfied.
Points out that increased thermal insulation and draughtproofing of homes can increase the risk to health of indoor air pollution. Includes condensation as a pollutant along with associated mould growth. Notes collaboration by Pilkington the glass company and the Timber Research and Development Association plus Laing the housebuilding group, to combat condensation by passive ventilation. Treats sources of indoor air pollution - formaldehyde, asbestos, gas appliances, tobacco smoke, thoron, radon.
Formaldehyde dosimeters have been tested in urea-formaldehyde foam insulated Canadian homes in which formaldehyde levels range from 0.02 to 0.2ppm. Performance of commercial and experimental passive dosimeters was evaluated over 2- to 4- and
A booklet for consumers explaining the effects of house-tightening measures on pollutant levels. It also provides a guide to detecting and controlling pollutants commonly found in homes.
