0000001530 00000 n Formaldehyde-induced carcinogenicity appears to be a consequence of proliferative regeneration following cytotoxicity (Environment Canada, Health Canada 2001). In the field of IAQ research, the term \"volatile organic compound\" or \"VOC\" refers to any of thousands of organic (carbon-containing) chemicals that are present mostly as gases at room temperature. The MEL for formaldehyde is hard to explain in the light of HSE's own toxicology review which found that eye irritation can be caused by exposure to levels as low as 0.01ppm, 200 times less than the MEL. 0000004636 00000 n Exposure levels In the UK formaldehyde has been assigned a Maximum Exposure Limit (MEL) of 2 parts per million (ppm). 0000003802 00000 n RfD. ) If someone in your home smokes tobacco products, the smoke may be the greatest source of formaldehyde in your home. In this report, formaldehyde concentrations in air are reported preferably as weight per volume (mg/m3 or pg/m3; 1 mg/m3 = 1,000 pg/m3). Thousands of homeowners used Assay Technology’s aldehyde badge (571) to determine if the level of formaldehyde in their homes was dangerous. NIOSH REL: 0.016 ppm TWA, 0.1 ppm 15-minute CEILING; NIOSH considers formaldehyde to be a potential occupational carcinogen as defined by the OSHA carcinogen policy [29 CFR 1990]. Formaldehyde. Thresholds were 1.2 ppm (1.5 mg/m3) for eye and nose irritation, 1.7 ppm (2.1 mg/m3) for eye blinking, and 2.1 ppm (2.6 mg/m3) for throat irritation. Occasionally, concentrations are also reported in terms of volume per volume (ppm, 1 ppm = 1.2 mg/m3). At 100 ppb, most adults experience eye, nose, and throat irritation.

Results from studies carried out in Canada since the early 1990s consistently indicate that formaldehyde concentrations in Canadian homes range between 2.5 and 88 µg/m 3 with an average between 30 and 40 µg/m 3 (Health Canada 2005). 0000002671 00000 n �� k�%8�e�6s(��Ϙ��l�خ�NF�~Z��r�^����Pk�s�P�!G>�#�L�T����1a��E�)�NS4:�q%���f1�u400[4��l@1A� ������J %�@fh(��2C $�2��h``� ��$��g� Zԡ������ ���ݡ� The healthcare sector should, however, minimise exposure to formaldehyde and is encouraged to respect the limit value of 0.37 mg/m3 or 0.3 ppm during the transitional period where possible’ [7] Information on formaldehyde and the regulation of formaldehyde emissions from composite wood products under the Formaldehyde Standards for Composite Wood Products Act in the Toxic Substances Control Act (TSCA).
