F ormal dehyde (methyl aldehyde, methylene oxide) is a ubiquitous compound found endogenously in the body and environment. It is a colorless, flammable gas with a distinct, pungent odor and is most commonly available in aqueous solutions under the name f ormalin (37% f ormaldehyde in water). F ormaldehyde has been used as a disinfectant, an embalming agent, and in industry as a precursor in the fabrication of complex compounds. Since scientific research has identified links between f ormaldehyde and adverse health effects, precautions and protections must be considered during use.
F ormaldehyde is used in the manufactureof phenolic resins, cellulose esters, artificialsilk, dyes, explosives, and organic chemicals.Other uses are as a germicide, fungicide, anddisinfectant; in tanning, adhesives, waterproofingfabrics, and for tonic and chromeprinting in photography; and for treating skindiseases in animals. In vitro neutralizationof scorpion venom toxicity by f ormaldehydehas been reported (Venkateswarlu et al.1988).
F ormaldehyde constitutes about 50% ofall aldehydes present in the air. It is oneof the toxic effluent gases emitted fromburning wood and synthetic polymeric substancessuch as polyethylene, nylon 6, andpolyurethane foams. Firefighters have a greaterrisk to its exposure. Incapacitation fromthe toxic effluent gases is reported to occurmore rapidly from the combustion of syntheticpolymers than from that of naturalcellulose materials.
F ormaldehyde is directly emitted into theair from vehicles. It is released in traceamounts from pressed wood products suchas particleboard and plywood paneling, fromold "sick" buildings, and from cotton andcotton-polyester fabrics with selected crosslinkfinishes. Formation of f ormaldehyde hasbeen observed in some frozen gadoid fishdue to enzymic decomposition of the additivetrimethylamine oxide (Rehbein 1985).Its concentration can build up during frozenstorage of fish (Leblanc and Leblanc 1988;Reece 1985). It occurs in the upper atmosphere,cloud, and fog; it also forms inphotochemical smog processes.
More than half of the commercial f ormaldehyde produced is used to manufacture phenolic,urea, and melamine f ormaldehyde resins. Polyacetyl resins use another 5-10% of f ormaldehyde,and approximately 80% of f ormaldehyde goes into the resins and plastics industry.Phenolic-f ormaldehyde resins were the first synthetic plastics to be produced. The first plasticwas called Bakelite.
F ormal dehyde has traditionally been used as a preservative in biology and medical laboratoriesand in embalming fluid. Embalming fluids typically contain 5-15% f ormal dehyde, a significant percentage of alcohol, and other additives to perform certain functions, for example,bleaches and coloring to preserve skin color. F ormaldehyde has been used to preserve deadbodies since 1900 and has several qualities that make it the preferred preservative. Foremostamong these is its low cost, but it also has several biochemical advantages: it kills germs andmicroorganisms, destroys decomposition enzymes, retards decomposition of proteins, andhardens body tissues.
F ormaldehyde is used as the preservative; disinfectant; antiseptic; in embalming solutions; in the manufacture of phenolic resins, artificial silk, cellulose esters, dyes, urea, thiou rea, melamine res ins, organic chemicals, glass mirrors and explosives; used in improving fastness of dyes on fabrics; in tanning and preserving hides; in mordanting and waterproofing fabrics; as a germicide and fungicide for vegetables and other plants; in destroying flies and other insects; in preserving and coagulating rubber latex; prevent mildewand spelt in wheat and rot in oats; used to ren der casein, albumin, and gelatin insoluble; in chemical analysis; as a tissue fixative; as a component of particle board and plywood; in the manufacture of pentaery thritol, hexame thylenetetramine and lkbutanediol; used in ceiling and wall insulation; in res ins used to wrinkle-proof fabrics; in photography for hardening gelatin plates and papers, for toning gelatin-chloride papers and for chrome printing and developing; intermediate in drug manufacture; pesticide intermediate; in the production of urea, phenolic melamine and acetale resins; in textile products; as an astringent, disinfectant, and preservative in cosmetics, metal-working fluids, shampoos, etc.; antiperspirant in cosmetics; anticracking agent in dental plastics; in anhidrotics; chipboard production; in cleaning products, disinfectants and deodorizers, dry-cleaning materials, and glues; in mineral-wool production, paints and coatings, paper industry, phenolic resins and urea plastics; in adhesives and footwear, photographic paper and solutions, polishes, printing materials, tanning agents, wart remedies, embalming solutions, fertilizers, wood composites, and insulation.
