Formaldehyde in the home atmosphere. Formaldehyd i boligluft.

During the period 1973-76, measurements in housing where particle board is used as a building material have revealed a reduction in the formaldehyde content of the indoor atmosphere from 0.64 to 0.40 mg/cu.m. under standard indoor climatic conditions. A corresponding although slighter reduction in therelease of formaldehyde from particle board was found under controlled conditions in climatic chambers. Suggests these improvements in the quality of particle board will suffice to fulfill the proposed limit of 0.40 mg/cu.m. Concludes from a review of recent literature that the upper limit for CHCO in housing should be 0.15 mg/cu.m. or less. Notes in spring 1978 an upper limit of 0.12 mg/cu.m. was introduced for housing in the Netherlands and that several other West European countries have made proposals concerning limiting values for CHCO.
