Washington, DC 20460 The results of this research have provided EPA and the Occupational Safety and Health Administration (OSHA) with information to evaluate the potential health effects of workplace exposure to formaldehyde. Here are a few of the problems we know of: Gastrointestinal effects. Of the questionnaires returned, 972 (70.6%) were analyzable. This analysis showed that those who had performed the most embalming and those with the highest estimated formaldehyde exposure had the greatest risk of myeloid leukemia. Much of the general literature on the effects of housing on health cites previous studies and then proceeds to advocate housing policies and strategies that are aimed at improving population health. The data from this study are representative of office workers in urban environments and can be used as background formaldehyde exposure levels (in the absence of specific sources) for both occupational and nonoccupational exposure assessments. Exposure to elevated levelscan lead to the accumulation of fluid in the lungs (pulmonary edema). In May 1992, the standard was amended, and the formaldehyde exposure limit was further reduced to 0.75 ppm. Imaging of the airways with multidetector row computed tomography. Therefore, some scientists think that formaldehyde is unlikely to have effects at sites other than the upper respiratory tract. Formaldehyde-exposed animals revealed with decreased serum level of testosterone (p < 0.05) and down-regulated antioxidant status versus control group. The U.S. Consumer Product Safety Commission (CPSC) has information about household products that contain formaldehyde. Urea-formaldehyde foam has become increasingly popular due to its excellent insulating characteristics and the shortages in fiberglass supplies. All content in this area was uploaded by Geoffrey Norman on Aug 21, 2015. This report describes the second survey of a group of 762 control and urea formaldehyde foam insulated (UFFI) houses performed following an interval of 1 year, after about two-thirds of the UFFI households either had their UFFI removed or performed other UFFI-related remedial work. Formaldehyde: health effects, incident management and toxicology Information on formaldehyde (also known as methanal and methylene glycol) for use in responding to chemical incidents. However the demonstrated adverse effects are generally minor in nature. “I remember how sick she was but we never, ever had a conversation with doctors about what the future would look like and how much time we had,” says Seow. In 1987, the U.S. Environmental Protection Agency (EPA) classified formaldehyde as a probable human carcinogen under conditions of unusually high or prolonged exposure (1). The authors conclude that there was no evidence of respiratory problems resulting from UFFI in the sample studied. Evidence from the adequate studies provides little support for the hypothesis of a causative role of UFFI in health problems. An NCI case-control study among funeral industry workers that characterized exposure to formaldehyde also found an association between increasing formaldehyde exposure and mortality from myeloid leukemia (4). 1982 Dec; 29 (2):320–334.

When formaldehyde is present in the air at levels exceeding 0.1 ppm, some individuals may experience adverse effects such as watery eyes; burning sensations in the eyes, nose, and throat; coughing; wheezing; nausea; and skin irritation. Department of Health and Human Services, Public Health Service, National Toxicology Program. The presence of formaldehyde in biologically active concentrations in several occupational and environmental atmospheres has created concern about the hazards of exposure to these contaminated atmospheres. The support for a causal relationship between impaired health and living in a UFFI house is considered to be moderately strong. If you would like to reproduce some or all of this content, see Reuse of NCI Information for guidance about copyright and permissions. The onset of respiratory irritation and other health effects, and even increased cancer risk, begin when air concentrations exceed 3.0–5.0 ppm. There is evidence that exposure to high levels of airborne formaldehyde can lead to respiratory problems and other health issues. A questionnaire concerning health and living conditions was sent to the parents of 1387 children aged 0-15 years to answer the question if children living in homes built with large amounts of particle board had more headaches and respiratory and skin symptoms than other children. EPA Formaldehyde Research and Risk … Studies of health effects of urea formaldehyde foam insulation (UFFI) were critically reviewed by means of accepted rules for evidence of causation. Regulation of formaldehyde releasers (entries 27, 46, 51, 55, Annex VI, part 1) together with formaldehyde and paraformaldehyde (entry 5, Annex VI, part 1) The maximum authorised concentrations of imidazolidinyl urea, diazolidinyl urea, sodium hydroxymethyl glycinate and benzylhemiformal in cosmetic products are based on the risk Most of the studies purporting to demonstrate health effects of UFFI failed to meet minimal methodologic criteria for evidence of causation. Eight of the 11 subjects with attention span deficits had elevated depression scores. Mortality from lymphohematopoietic malignancies and brain cancer among embalmers exposed to formaldehyde. Where can people find more information about formaldehyde? These products emit less formaldehyde because they contain phenol resins, not urea resins. Formaldehyde may also be used under restriction in the EUas a preservative in cosmetics and nail hardening products. I discuss the factors that influence establishment of 'safe' conditions or levels of exposure to formaldehyde. 111 TW Alexander Drive U.S. Environmental Protection Agency, Office of Air and Radiation. Indoor Environments Division In approximate order of decreasing consumption, products generated from formaldehyde include urea formaldehyde resin, melamine resin, phenol formaldehyde resin, polyoxymethylene plastics, 1,4-butanediol, and methylene diphenyl diisocyanate.

In addition, formaldehyde is commonly used as an industrial fungicide, germicide, and disinfectant, and as a preservative in mortuaries and medical laboratories. It can irritate the nose and throat, causing sneezing, soreness, coughing, shortness of breath, headaches, and nausea. Health concerns. However, some laboratory studies suggest that formaldehyde may affect the lymphatic and hematopoietic systems. Journal of the National Cancer Institute 2003; 95(21):1608–1615. Before purchasing pressed-wood products, including building materials, cabinetry, and furniture, buyers should ask about the formaldehyde content of these products. Some people are very sensitive to formaldehyde, whereas others have no reaction to the same level of exposure. During the 1970s, urea-formaldehyde foam insulation (UFFI) was used in many homes. Skin testing did not reveal an increased prevalence of atopy or reaction to 4% formalin. Pinkerton LE, Hein MJ, Stayner LT. Mortality among a cohort of garment workers exposed to formaldehyde: An update. When formaldehyde is present in the air at levels higher than 0.1 parts per million (ppm), some people may have health effects, such as: watery eyes; burning sensations of the eyes, nose, and throat; coughing; wheezing; nausea; skin irritation 1977 Sep 15; 39 (4):207–218. The National Toxicology Program (NTP) is an interagency program of the Department of Health and Human Services that was created to coordinate toxicology testing programs within the federal government; to develop and validate improved testing methods; and to provide information about potentially toxic chemicals to health, regulatory, and research agencies, scientific and medical communities, and the public. However, the evidence remains mixed because a cohort study of 14,014 British industry workers found no association between formaldehyde exposure and leukemia deaths (8). One study, conducted by NCI, looked at 25,619 workers in industries with the potential for occupational formaldehyde exposure and estimated each worker’s exposure to the chemical while at work (5).

Formaldehyde is a colorless, flammable, strong-smelling chemical widely used to make home building products. Formaldehyde undergoes rapid chemical changes immediately after absorption. The minimal concentration of formaldehyde that can be detected by odor is similar to the level that produces minimal irritant effects on the eyes and in the pulmonary airway, thereby serving as a warning of exposure to the compound. There was no association with other cancers of the hematopoietic and lymphatic systems or with brain cancer. Urea formaldehyde and other resins: what are the health effects? The irritant effects are reversible when exposure is discontinued. Being as common as it is, it’s only natural to wonder about the effects of increased levels of formaldehyde on environmental health, and especially public health. Personal 24-h formaldehyde concentrations in one location were significantly higher than concentrations measured in the other four locations; no significant differences existed between any of the other locations. increased allergic sensitivity. The most recent data on lung cancer from the cohort study did not find any relationship between formaldehyde exposure and lung cancer mortality. National Toxicology Program (June 2011). The total free formaldehyde content in a product containing 0.5% diazolidinyl urea will thus correspond to 0.215%.
