Here are a few of the problems we know of: Gastrointestinal effects. 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. To evaluate the effect of formalin exposure on the testicular tissue and sperm parameter from neonatal period through physical and sexual maturity, 28 male Wister rats were assigned into two equal test and control groups. Eye: the health effects on the eye can include stinging, itching and burning. 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. Urea-Formaldehyde Concentrate, UFC 85 Section 1. Increased regulatory activity, including exposure limits, guidelines, and elimination of certain building materials, have generally reduced the exposure potential since the mid-1980s (ANSES 2016;ATSDR 2010;US EPA 2016a). Data from extended follow-up of the NCI cohort found that the excess of nasopharyngeal cancer observed in the earlier report persisted (9). There were 1376 possible respondents, and of those 1036 (75.3)% returned the questionnaire. One type of epidemiologic study is called a cohort study. (Pressed-wood products include plywood, paneling, particleboard, and fiberboard and are not the same as pressure-treated wood products, which contain chemical preservatives and are intended for outdoor use.) The EPA recommends the use of “exterior-grade” pressed-wood products to limit formaldehyde exposure in the home. Department of Health and Human Services, Public Health Service, National Toxicology Program. This analysis continued to show a possible link between formaldehyde exposure and cancers of the hematopoietic and lymphatic systems, particularly myeloid leukemia. 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. Comparison of Health of Occupants and Characteristics of Houses Among Control Homes and Homes Insulated With Urea Formaldehyde Foam. Median personal 24-h formaldehyde concentrations ranged from 9.9 to 18 μg/m3. formaldehyde has been linked to this cancer in industrial workers regularly exposed to high levels of the gas. The EPA can be contacted at: U.S. Environmental Protection Agency It is mainly used to produce other chemicals and in the production of resins. This observation led the researchers to conclude that factors other than formaldehyde exposure might have caused the increased deaths. Most formaldehyde produced in the United States is for the manufacture of resins, such as urea-formaldehyde, used to make the adhesives for pressed wood products, such as particleboard, furniture, paneling, cabinets, and other products. Environ Res. The authors conclude that there was no evidence of respiratory problems resulting from UFFI in the sample studied. An air sampling study was conducted to evaluate personal formaldehyde exposures in a group of office workers spread across five geographical locations in the USA. Occupational Environmental Medicine 2004; 61:193–200. In 1980, laboratory studies showed that exposure to formaldehyde could cause nasal cancer in rats. All content in this area was uploaded by Geoffrey Norman on Aug 21, 2015. • The health risks posed by exposures to formaldehyde, including potential cancer outcomes, have been highlighted in a number of reports by Australian and overseas agencies. He was volunteering at a nursing home, helping older, isolated men shave, playing piano for them, and spending time with them. Eight of the 11 subjects with attention span deficits had elevated depression scores. During the 1970s, urea-formaldehyde foam insulation (UFFI) was used in many homes. 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. 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. different types of scan, the use of low-dose protocols for paediatric imaging and appropriate reconstruction techniques. 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. It is also possible that insufficient curing allows monomeric formaldehyde to be trapped within the hardened foam. Mortality from lymphohematopoietic malignancies among workers in formaldehyde industries: The National Cancer Institute Cohort. There was no association with other cancers of the hematopoietic and lymphatic systems or with brain cancer. Washington, DC 20460 1–800–321–6742 (1–800–321–OSHA) Studies of health effects of urea formaldehyde foam insulation (UFFI) were critically reviewed by means of accepted rules for evidence of causation. A HPLC method for the analysis of diazolidinyl urea in an experimental cream was published in 1997 (5). A brief discussion of the biochemistry and toxicity of formaldehyde is presented. 1982 Dec; 29 (2):320–334. Another kind of epidemiologic study is called a case-control study. High levels of exposure may cause some types of cancers. Formaldehyde is a colorless, flammable, strong-smelling chemical that is used in building materials and to produce many household products. The mechanisms through which specific aspects of housing affect health are extremely complicated, but they do exist. 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 this is a rare type of cancer. American Journal of Epidemiology 2004; 159(12):1117–1130. 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). Retrieved June 10, 2011, from: A two- to four-hour curing period results in a hardened urea-formaldehyde resin which dries to completion in one to two days. Living in a home with much particle board was a risk factor for all three conditions. Risks declined steadily over time, such that the cumulative excess risk of myeloid leukemia was no longer statistically significant at the end of the follow-up period. 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. Formaldehyde undergoes rapid chemical changes immediately after absorption. Formaldehyde can cause irritation of the skin, eyes, nose, and throat. The reaction is theoretically a reversible one, and herein lies the source of a potential health hazard. 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. 2. Health effects occur when UF-based materials and products release formaldehyde into the air. This finding raised the question of whether formaldehyde exposure could also cause cancer in humans. A cohort study of 11,039 textile workers performed by the National Institute for Occupational Safety and Health (NIOSH) also found an association between the duration of exposure to formaldehyde and leukemia deaths (7). An early U.S. study conducted in 1985 investigated formaldehyde levels in different types of housing. A major controversy then started, with on the one hand several consumer associations, and on the other, the UFFI raw materials producing … In conclusion, the current data provide inclusive histological and biochemical information about the chronic exposure to formaldehyde with emphasizing on reproductive disorders including histological adverse effects on the testicular tissue, spermatogenesis, sperm viability, count and the abnormalities which can potentially cause infertility after sexual maturation. NTP is headquartered at the National Institute of Environmental Health Sciences, which is part of NIH. Hyattsville, MD 20782–7055 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. very high levels (levels higher than those found in Canadian homes) can cause cancer of the nasal cavity. For the 6- to 15-year-old children, living in a home with much particle board was not a risk factor. Other potential indoor sources of formaldehyde include cigarette smoke and the use of unvented fuel-burning appliances, such as gas stoves, wood-burning stoves, and kerosene heaters. (Hematopoietic or hematologic cancers such as leukemia develop in the blood or bone marrow. So just because it’s not listed on your product doesn’t necessarily mean there aren’t any formaldehyde exposure risks. But urea formaldehyde has been blamed for more sinister problems too. For… A review of the clinical and animal toxicologic data demonstrate both primary irritant and sensitizing actions of the compound. The UFFI subjects who lived in remedial houses showed a decline in indicators of impaired health status, to roughly equalize with those whose houses were not altered; they continued to show a small excess of adverse health indicators relative to the controls, but at a somewhat lower level than seen in the first survey. The environment and disease: Association or causation, Health effects associated with urea-formaldehyde foam insulation in Connecticut. 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. The support for a causal relationship between impaired health and living in a UFFI house is considered to be moderately strong. Report to Congress on Indoor Air Quality, Volume II: Assessment and Control of Indoor Air Pollution, 1989. International Agency for Research on Cancer (June 2004). Building 101 He was 10 when she died. 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. 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). © 2008-2020 ResearchGate GmbH. The onset of respiratory irritation and other health effects, and even increased cancer risk, begin when air concentrations exceed 3.0–5.0 ppm. However the demonstrated adverse effects are generally minor in nature. 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). Fortunately, it is one of the best-studied of environmental chemicals in the United States. When Chelsea Gabel started studying how online voting contributes to First Nations’ capacity to ratify their own legislation, it was still a very new idea — she figures maybe 15 Indigenous communities in Canada used online voting... Hsien Seow was six when his mother was diagnosed with breast cancer. 202–554–1404 (EPA Toxic Substance Control Act (TCSA) Assistance Line) However, specific work practices and exposures were not characterized in these studies. Can Med Assoc J. Spirometry was normal in all subjects, and bronchial reactivity was not significantly different from a population-based response to the same challenge. 919–541–0530 If you don’t … Before purchasing pressed-wood products, including building materials, cabinetry, and furniture, buyers should ask about the formaldehyde content of these products. For the 0- to 5-year-old children, living in homes with much particle board was a risk factor for developing wheezy bronchitis, eye and nose irritation, and coughing. Access scientific knowledge from anywhere. As in the initial study, the risk was highest earlier in the follow-up period. A number of cohort studies involving workers exposed to formaldehyde have recently been completed. Coronavirus: Find the latest articles and preprints ... Thun MJ, Lakat MF, Altman R. Symptom survey of residents of homes insulated with urea--formaldehyde foam. 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. There is evidence that exposure to high levels of airborne formaldehyde can lead to respiratory problems and other health issues. The irritant effects are reversible when exposure is discontinued. PMCID: PMC1483378 PMID: 6733625 When the, The wide availability of multidetector row computed tomography (MDCT) continues to change the way we manage patients. A power calculation indicated that the study had adequate power to detect clinically important changes. U.S. Environmental Protection Agency, Office of Air and Radiation. Hauptmann M, Lubin JH, Stewart PA, Hayes RB, Blair A. Mortality from solid cancers among workers in formaldehyde industries. The paediatric respiratory and radiology teams should therefore be familiar with this technique. 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. Studies providing original data on the relationship, which is the vast majority of the literature, focus on very specific physical, chemical, and biological exposures with a known or suspected effect on health within the house, or they focus on the social, economic, and cultural characteristics of the house. 5. Although it is generally agreed that this decomposition is a result of improperly cured foam, it is not known whether the problem occurs at the time of manifacture, mixing, or installation. 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. Kane LE, Alarie Y. … All rights reserved. No significant differences in any variable were found between the subjects and controls. Formaldehyde is produced in large quantities industrially. 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. 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. Extended follow-up of a cohort of British chemical workers exposed to formaldehyde. increased allergic sensitivity. Under certain conditions the resin begins to decompose and release free formaldehyde gas to the environment. In 1983, the media brought out articies expressing serious concerns as to the use of Urea Formaldehyde Foam Insulation (UFFI). Occupational Safety and Health Administration The dust from other glues may also have irritating or sensitizing properties. Formaldehyde is a carcinogenic impurity released by a number of cosmetic preservatives, including diazolidinyl urea, imidazolidinyl urea, DMDM hydantoin, quaternium-15, 2-bromo-2-nitropropane-1,3-diol, and sodium hydroxylmethylglycinate. How is the general population exposed to formaldehyde? Urea-formaldehyde foam insulation has recently become the subject of great concern due to the health effects associated with its use. 1982 Dec; 29 (2):320–334. If you’re worried that your home may have been insulated with it, it’s best to get a professional to take a look. 5. Silver Spring, MD 20993–0002 Materials containing formaldehyde can release formaldehyde gas or vapor into the air. 1–800–638–2772 (1–800–638–CPSC) 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. Herstellung. Formaldehyde is a common precursor to more complex compounds and materials. Lymphatic cancers develop in the tissues and organs that produce, store, and carry white blood cells that fight infections and other diseases.) People exposed to such formaldehyde-releasing ingredients may develop a formaldehyde allergy or an allergy to the ingredient itself. Health and House Variables Following Remedial Work. 1. 200 Constitution Avenue In addition, formaldehyde is commonly used as an industrial fungicide, germicide, and disinfectant, and as a preservative in mortuaries and medical laboratories. Based on both the epidemiologic data from cohort and case-control studies and the experimental data from laboratory research, NCI investigators have concluded that exposure to formaldehyde may cause leukemia, particularly myeloid leukemia, in humans. How can people limit formaldehyde exposure in their homes? This improvement was not associated with changes in indoor levels of formaldehyde. 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. The test group was exposed to 1.5 ppm of the vapor of 10% formaldehyde in a special chamber for 2 hr per day at 20-26 ˚C and the air pressure of 760-763 atm. Formaldehyde is currently used as a feed additive and as a preservative for skimmed milk intended for pigs. Industrial workers who produce formaldehyde or formaldehyde-containing products, laboratory technicians, certain health care professionals, and mortuary employees may be exposed to higher levels of formaldehyde than the general public. The foam is produced when urea and formaldehyde are combined with a catalyst and forced from a nozzle under pressure. 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. Weak exposure-response relationships were observed between formaldehyde and upper and lower respiratory symptoms, but mainly in the combined UFFI and control populations; these are interpreted as representing the contribution of background levels of formaldehyde to the prevalence of respiratory complaints in the general population. Research Triangle Park, NC 27709 Hauptmann M, Stewart PA, Lubin JH, et al. 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. NTP can be contacted at: National Toxicology Program FDA can be contacted at: U.S. Food and Drug Administration The International Agency for Research on Cancer (IARC) classifies formaldehyde as a human carcinogen (2). One source of formaldehyde exposure in the air is automobile tailpipe emissions. Health risks of urea formaldehyde foam insulation. 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. Formaldehyde can irritate the eyes, skin and respiratory tract and prolonged exposure could cause skin sensitisation and allergic contact dermatitis. What has been done to protect workers from formaldehyde? Homes in which UFFI was installed many years ago are not likely to have high formaldehyde levels now. The U.S. Consumer Product Safety Commission (CPSC) has information about household products that contain formaldehyde. The role of the hemolytic Streptococcus in the precipitation of both initial and recurrent attacks of rheumatic fever is now well established. Beane Freeman L, Blair A, Lubin JH, et al. Formaldehyde also occurs naturally in the environment. Appropriate measures should be taken to reduce worker exposure to feed containing formaldehyde. Doug Oliver's first experience in health care came in his 20s. I discuss the factors that influence establishment of 'safe' conditions or levels of exposure to formaldehyde. The emission of formaldehyde vapours within UFF insulated homes was held responsible for «serious health problems». The most recent data on lung cancer from the cohort study did not find any relationship between formaldehyde exposure and lung cancer mortality. The formaldehyde-exposed animals showed severe seminiferous tubules atrophy, edematous connective tissue, arrested spermatogenesis with negative TDI and RI and vascular thrombosis compared to control group. Risk factors for headache, irritation of the throat, and need for daily antiasthmatic medication were analyzed for all the children collectively. Studies of health effects of urea formaldehyde foam insulation (UFFI) were critically reviewed by means of accepted rules for evidence of causation. An additional 10 years of data on the same workers were used in a follow-up study published in 2009 (6). Memory difficulty was a frequently reported symptom. When inhaled in its gaseous form, formaldehyde is a known carcinogen and can cause a number of adverse health effects. Weber-Tschopp A, Fischer T, Grandjean E. Reizwirkungen des Formaldehyds (HCHO) auf den Menschen. A large gap still exists in our knowledge about the links and pathways between housing, socio-economic status and health status. Health concerns. 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. 1–888–463–6332 (1–888–INFO–FDA) Health Effects of Formaldehyde Exposure. However, the rate of lung cancer deaths did not increase with higher levels of formaldehyde exposure. Formaldehyde is highly toxic to humans, regardless of the intake method. III. Once the domain of the specialist paediatric centre, imaging of the paediatric thorax now routinely occurs in many general hospitals. Passive badge samples for formaldehyde were collected on three participants in each location, as well as in the office and home indoor microenvironments of each participant over 3 individual days. The results showed an increased risk of death due to leukemia, particularly myeloid leukemia, among workers exposed to formaldehyde. The Housing/Health Relationship: What Do We Know? It is produced in small amounts by most living organisms as part of normal metabolic processes. Does formaldehyde cause any other health problems?
