Describes a study which examined the effect of temperatures of 23, 29, and 50 Deg C on formaldehyde and volatile organic compounds (VOCs) emission from laminate flooring Type A (with particleboard as substrate) and Type B (with high density fibre (HDF). For the first two temperatures, the measurements did not show any emissions of formaldehyde and very low emissions of VOCs. At the highest temperature however, Type A showed a high initial emission of formaldehyde and VOCs, decreasing with time. There were much lower emissions from Type B.
Perceived air quality, symptoms, and perception of the environment were studied in a naturally ventilated office building in which a felt carpet was substituted by linoleum on the first floor and by polyolefine floor tiles, known from previous studies to be a low-polluting floor material on the second floor, while the felt carpet remained unchanged on the ground floor. A panel of 36 untrained subjects occupied the offices on each storey for a period of one hour in a balanced design on a day when normal occupants were absent.
