In 1979 formaldehyde was projected into the toxicological limelight when Kerns and his group from the American Chemical Industry Institute of Toxicology (CIIT) released preliminary results of an inhalation study on male and female rats. Those animals exposed to 14.3 p.p.m. for 8 h/day and 5 days/week for up to 2 years showed the development of squamous

Formaldehyde, one of the most toxic organic compounds, is produced and processed in human cells. The level of human endogenous formaldehyde is maintained at a low concentration (0.01-0.08 mmol L(-1) in blood) under physiological conditions, but the concentration increases during ageing (over 65 years old).

The IARC's 2004 classification of formaldehyde as a human carcinogen has led to intensive discussion on scientific and regulatory levels. In June 2014, the European Union followed and classified formaldehyde as a cause of cancer. This automatically triggers consequences in terms of emission minimization and the health-related assessment of building and

Formaldehyde and Formaldehyde Releasers
2000Formaldehyde is a commonly occurring chemical substance and a frequent contact allergen in many countries (Flyvholm 1997). Allergic reactions to formaldehyde can be provoked by exposure to formaldehyde that is added to chemical products or derived from preservatives that release formaldehyde into the products, i.e. formaldehyde releasers.

Formaldehyde Cycle and the Natural Formaldehyde Generators and Capturers
Acta Biologica Hungarica, 1998S-adenosyl-L-methionine serves as a methyl donor in virtually all of the vast number of enzymatic transmethylation reactions including DNA methylation. On the basis of our former experiences we questioned the formation of a methyl cation or methyl radical in the enzymatic transmethylation reactions.

Occupational contact allergy to formaldehyde and formaldehyde releasers
Contact Dermatitis, 2008Background: Formaldehyde allergy is common and usually derives from formaldehyde‐releasing biocides in cosmetic and other products.Objectives: To analyse patterns of patch test reactions to formaldehyde and formaldehyde‐releasing compounds and the sources of sensitization.Patients/Methods: At the Finnish Institute of Occupational Health, we screened

AbstractSubstances referred to as formaldehyde releasers were identified on review of the literature. Information on product categories and typical concentrations for chemical products containing formaldehyde and formaldehyde releasers was obtained from the Danish Product Register Data Base (PROBAS). As of February 1992, 62,000 products were registered

Determination of formaldehyde in formaldehyde‐releaser patch test preparations
Contact Dermatitis, 2010Background: Positive patch test reactions to formaldehyde‐releasers in patients co‐reacting to formaldehyde are often ascribed to formaldehyde allergy. However, the formaldehyde content of patch test materials has not been investigated. Objectives: To demonstrate and quantify free formaldehyde in commercial patch test materials and in prepared aqueous

Urea-Formaldehyde Resins and Free Formaldehyde Content
Acta Biologica Hungarica, 1998Specifications of wood adhesives must be in correlation with the requirements for the corresponding wood products, for which they will be used. Formaldehyde emission of wood products bonded with urea-formaldehyde resin based adhesives is strictly regulated by standards and there is a compromise is between formaldehyde emission and performance, such as ...

Residual formaldehyde in steam-formaldehyde sterilized materials
Biomaterials, 1986The amounts of residual formaldehyde and paraformaldehyde present in polymeric materials after steam-formaldehyde sterilization in a commercial sterilizer were determined. Appreciable amounts of residue were detected in ethylene-vinyl alcohol copolymer (EVOH), polyamide-6 (PA-6) and natural rubber (NR).
