This is one of series of review articles on formaldehyde and formaldehyde-releasers (others: formaldehyde in cosmetics, in clothes and in metalworking fluids and miscellaneous). Thirty-five chemicals were identified as being formaldehyde-releasers. Although a further seven are listed in the literature as formaldehyde-releasers, data are inadequate to consider them as such beyond doubt. Several ...

Problem statement: Formaldehyde was classified as a potential human carcinogen, identified by the US Environmental Protection Agency and International Agency for Research on Cancer as a Class 2A carcinogen. It also can cause irritation to human. However, formaldehyde present in biological fluids or tissues and environment as a result of natural processes or from man-made sources and can be emit...

One of the airborne pollutants in wood products industry is formaldehyde, which may pose some health effects. Therefore this study is conducted to determine formaldehyde levels in 100 furniture-manufacturing workshops in Ankara and also to determine the symptoms, which may be related with formaldehyde exposure among the workers. Indoor formaldehyde levels ranged from 0.02 ppm to 2.22 ppm with a...

background: one of the pollutant components that can be observed in many industrial wastewaters is formaldehyde. the biological treatment of the wastewater contaminated by formaldehyde is very difficult due to its antibacterial property. however the removal of formaldehyde using adsorption process is feasible but it may be expensive. the main purpose of this study is to examine the adsorption o...

Rapoport (1946), Kaplan (1948), and Auerbach (1949) found formaldehyde highly mutagenic for Drosophila when administered with its food. Auerbach (1949), however, observed negative results when Drosophila was exposed to formaldehyde vapor and concluded that formaldehyde acts indirectly through chemical changes brought about in food constituents. Dickey, Cleland, and Lotz (1949) found formaldehyd...

partial replacement of formaldehyde with furfural in the urea-formaldehyde resin on the formaldehydeemission, physical and mechanical properties of particleboard was investigated. the modulus ofrupture (mor), modulus of elasticity (moe), internal bond (ib), water absorption (wa), thicknessswelling (ts) and formaldehyde emission (fe) of poplar particleboards made with the modifiedresins were mea...

photocatalytic reduction of carbon dioxide to formaldehyde was investigated on four semiconductor photocatalysts (fes, fes/fes2, nio and tio2). the reaction was carried out in continues flow of co2 gas bubbled into the reactor. semiconductor photocatalysts were characterized by x-ray diffraction (xrd) and diffuse reflectance spectroscopic (drs) methods. sulfide ion was used as hole scavenger. t...

Formaldehyde is a one-carbon, highly water-soluble aldehyde that is used in certain vaccines to inactivate viruses and to detoxify bacterial toxins. As part of the manufacturing process, some residual formaldehyde can remain behind in vaccines at levels less than or equal to 0.02%. Environmental and occupational exposure, principally by inhalation, is a continuing risk assessment focus for form...

Pseudomonas putida KT2440 exhibits redundant formaldehyde dehydrogenases and formate dehydrogenases that contribute to the detoxification of formaldehyde, a highly toxic compound. Physical and transcriptional analyses showed that the open reading frame (ORF) PP0328, encoding one of the formaldehyde dehydrogenases, is self-sufficient, whereas the other functional formaldehyde dehydrogenase gene ...

Concomitant contact allergy to formaldehyde and formaldehyde-releasers remains common among patients with allergic contact dermatitis. Concentration of free formaldehyde in cosmetic products within allowed limits have been shown to induce dermatitis from short-term use on normal skin. The aim of this study was to investigate the formaldehyde content of cosmetic products made in Lithuania. 42 sa...
