Formaldehyde resins are used as adhesives and binders in many different industries that produce wood products, pulp and paper, synthetic fibres, plastics and coating and textiles. 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. The EPA can be contacted at: U.S. Environmental Protection Agency Want to use this content on your website or other digital platform? FDA can be contacted at: U.S. Food and Drug Administration Fortunately, it is one of the best-studied of environmental chemicals in the United States. Since the 1980s, the National Cancer Institute (NCI), a component of the National Institutes of Health (NIH), has conducted studies to determine whether there is an association between occupational exposure to formaldehyde and an increase in the risk of cancer. In their risk assessment, EFSA’s experts concluded that while there is no health risk for consumers exposed to this substance through the food chain, its inhalation may cause cancer. For… The very limited amount of toxicologic data concerned with effects from prolonged and chronic exposures suggest that the compound does not produce specific delayed types of toxicity. Weber-Tschopp A, Fischer T, Grandjean E. Reizwirkungen des Formaldehyds (HCHO) auf den Menschen. Die Harnstoff-Formaldehyd-Harze werden kurz als UF-Harze (von engl. Occupational Environmental Medicine 2004; 61:193–200. 1–800–321–6742 (1–800–321–OSHA)http://www.osha.gov. Formaldehyde is currently used as a feed additive and as a preservative for skimmed milk intended for pigs. Spirometry was normal in all subjects, and bronchial reactivity was not significantly different from a population-based response to the same challenge. 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 Before purchasing pressed-wood products, including building materials, cabinetry, and furniture, buyers should ask about the formaldehyde content of these products. 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. Several NCI surveys of professionals who are potentially exposed to formaldehyde in their work, such as anatomists and embalmers, have suggested that these individuals are at an increased risk of leukemia and brain cancer compared with the general population. The dust from other glues may also have irritating or sensitizing properties. Formaldehyde levels in homes can also be reduced by ensuring adequate ventilation, moderate temperatures, and reduced humidity levels through the use of air conditioners and dehumidifiers. Therefore, some scientists think that formaldehyde is unlikely to have effects at sites other than the upper respiratory tract. Chronic low level exposure to formaldehyde may cause significant mental status changes, but further testing of a larger, randomly population is necessary to evaluate this question. The research falls into four distinct categories: (1) specific physical or chemical exposures; (2) specific biological exposures; (3) physical characteristics of the house; and (4) social, economic, and cultural characteristics of housing. The authors conclude that there was no evidence of respiratory problems resulting from UFFI in the sample studied. The problem of control of the respiratory tract infections. Furthermore, it is general experience that hemolytic streptococcic respiratory infections in children and young adults who have previously had one or more attacks of rheumatic fever cause recurrence of the disease in 40 to 50% of instances. 111 TW Alexander Drive Formaldehyde –urea resin is used as an insulating material in building construction. Where can people find more information about formaldehyde? The support for a causal relationship between impaired health and living in a UFFI house is considered to be moderately strong. After 55 days, the tubular differentiation (TDI) and repopulation (RI) indexes in testicular tissue, sperm quality parameters, serum total antioxidant capacity and testosterone level were determined. Access scientific knowledge from anywhere. A cohort is a group of people who may vary in their exposure to a particular factor, such as formaldehyde, and are followed over time to see whether they develop a disease. The children lived in homes with much particle board (group A); little particle board, or homes as group A but treated in a special way (group B); and homes with no particle board (group C). Health problems related to houses insulated with urea-formaldehyde foam in the province of Quebec, 283 Respiratory effects of formaldehyde & UFFI off-gas following controlled exposure, Health effects of residence in homes with urea formaldehyde foam insulation: A pilot study, McMaster Engineering is hiring widely for faculty positions, Empowering older adults to live and age on, An innovative approach to palliative care, [Neural control of respiration. An early U.S. study conducted in 1985 investigated formaldehyde levels in different types of housing. A review of the clinical and animal toxicologic data demonstrate both primary irritant and sensitizing actions of the compound. The participants in this study spent an average of 53% of their daily time in their homes, 36% at their office, and 11% in other indoor and outdoor locations. “Even though I didn’t have any medical training at the time, I felt the power of what spending time with... “We do our research WITH Indigenous peoples, not ON them” People exposed to such formaldehyde-releasing ingredients may develop a formaldehyde allergy or an allergy to the ingredient itself. Health risks in homes insulated with urea formaldehyde foam. Urea-formaldehyde foam has become increasingly popular due to its excellent insulating characteristics and the shortages in fiberglass supplies. As in the initial study, the risk was highest earlier in the follow-up period. Mail Code 6609J EPA Formaldehyde Research and Risk … Formaldehyde can irritate the eyes, skin and respiratory tract and prolonged exposure could cause skin sensitisation and allergic contact dermatitis. National Toxicology Program (June 2011). Formaldehyde undergoes rapid chemical changes immediately after absorption. Patient preparation, with particular respect to sedation and optimal contrast bolus delivery, is also addressed. In addition, several case-control studies, as well as analysis of the large NCI industrial cohort (6), have found an association between formaldehyde exposure and nasopharyngeal cancer, although some other studies have not. There was no association with other cancers of the hematopoietic and lymphatic systems or with brain cancer. thermisch ausgehärtet werden können. III. Occupational Safety and Health Administration Memory storage deficits could not be documented, but 11 of 14 subjects had abnormal tests of attention span. 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. Indoor Environments Division If you’re worried that your home may have been insulated with it, it’s best to get a professional to take a look. Eye: the health effects on the eye can include stinging, itching and burning. this is a rare type of cancer. In the USA, the Consumer Product Safety Commission (CPSC) banned the use of urea formaldehyde foam insulation in 1982, which greatly reduced the exposure potential in the general public; however, it is unclear whether formaldehyde exposure from these products was the cause of the perceived health effects that led to the legislative ban (US EPA 2016a;Lees 1983; ... Histopathological examination revealed respiratory tract disorders, broncho-alveolar constriction and lung edema. Harnstoffderivaten) und Aldehyden (insbesondere Formaldehyd) hergestellt und chemisch bzw. Comparison of Health of Occupants and Characteristics of Houses Among Control Homes and Homes Insulated With Urea Formaldehyde Foam. The Occupational Safety and Health Administration (OSHA) has information about occupational exposure limits for formaldehyde. What have scientists learned about the relationship between formaldehyde and cancer? How is the general population exposed to formaldehyde? Formalin is widely used in industry and in medicine (as tissue fixative and disinfectant).It contains reactive molecules which have been known for its cytotoxic effects. increased allergic sensitivity. ... A possible solution to the design problem is a historical cohort study in which data obtained for other purposes are used. FEMA can be contacted at: Federal Emergency Management Agency The following organizations can provide additional resources that readers may find helpful: The EPA offers information about the use of formaldehyde in building materials and household products. Compendium of Chemical Hazards: Formaldehyde Page 3 of 16 Incident Management Formaldehyde solution with not less than 25%formaldehyde UN 2209 Formaldehyde solution, with not less than 25 % formaldehyde EAC 2X Use alcohol resistant foam but, if not available, fine water spray can be used. Formaldehyde is a colorless, flammable, strong-smelling chemical that is used in building materials and to produce many household products. In May 1992, the standard was amended, and the formaldehyde exposure limit was further reduced to 0.75 ppm. Formaldehyde can cause irritation of the skin, eyes, nose, and throat. Some people are very sensitive to formaldehyde, whereas others have no reaction to the same level of exposure. Join ResearchGate to find the people and research you need to help your work. Homes in which UFFI was installed many years ago are not likely to have high formaldehyde levels now. Retrieved June 10, 2011, from: http://ntp.niehs.nih.gov/go/roc12. Building 101 Formaldehyde is highly toxic to humans, regardless of the intake method. formaldehyde has been linked to this cancer in industrial workers regularly exposed to high levels of the gas. 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. 1–888–463–6332 (1–888–INFO–FDA)http://www.fda.gov. Median personal 24-h formaldehyde concentrations ranged from 9.9 to 18 μg/m3. From this data base 29 children who lived in UFFI-insulated homes were identified, and each was matched with 2 controls according to nine variables that had been shown to be strongly predictive of respiratory function. The use of a urea formaldehyde-based resin in the manufacture of UFFI can lead to the release of formaldehyde gas during the curing process and afterwards. Silver Spring, MD 20993–0002 Research into the relationship between housing and health has frequently been narrowly focused, fragmented, and of marginal practical relevance to either housing or health policy. As briefly highlighted in this review, having a concise knowledge of the chemistry of these processes will be an easy guide towards a suc- cessful synthesis of UF resins with improved performance and environmental attributes. diazolidinyl urea can release 4 molecules of formaldehyde under rigorous conditions. The onset of respiratory irritation and other health effects, and even increased cancer risk, begin when air concentrations exceed 3.0–5.0 ppm. 1982 Dec; 29 (2):320–334. No significant differences in any variable were found between the subjects and controls. These products emit less formaldehyde because they contain phenol resins, not urea resins. Some persons show allergic type responses to concentration of the compound that are well below the odor threshold. During the 1970s, urea-formaldehyde foam insulation (UFFI) was used in many homes. 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. Pinkerton LE, Hein MJ, Stayner LT. Mortality among a cohort of garment workers exposed to formaldehyde: An update. Formaldehyde emissions decrease over time. Formaldehyde is a colorless, flammable, strong-smelling chemical widely used to make home building products. This risk was associated with increasing peak and average levels of exposure, as well as with the duration of exposure, but it was not associated with cumulative exposure. A large data base on the effect of environmental variables on the respiratory function of 3500 children in the Hamilton, Ont., area had been collected from 1978 to 1980. different types of scan, the use of low-dose protocols for paediatric imaging and appropriate reconstruction techniques.
