Formaldehyde in present-day environmental toxicology

Prikazana je eko-toksikološka važnost formaldehida, osobito u njegovoj primjeni kao sastavnog dijela sintetskih smola koje se masovno upotrebljavaju u tekstilnoj, građevinskoj, drvnoj i kemijskoj industriji, u industriji namještaja, gume i plastike itd. Opisana su kemijska, fizička i biološka svojstva tog plina izvanredne reaktivnosti, a zatim glavni izvori njegovih emisija u profesionalnoj i općoj ekološkoj ekspoziciji. Iscrpno su prikazani tehnološki procesi primjene formaldehidnih smola, a zatim patološke promjene, koje su podijeljene na toksične, alergijske, mutagene i karcinogene, a s obzirom na lokalizaciju kao dermatološke i respiratorne.The importance of formaldehyde from the point of view of environmental toxicology is presented with special regard to the numerous applications of formaldehyde-containing synthetic resins in the textile industry, in building, wood and furniture, rubber, plastics and chemical industries, in medicine, etc. The chemical, physical and physiological properties of this gas of high chemical reactivity are described, as well as the main sources of its emanations in occupational and general environments. The technological processes in which formaldehyde resins are used are reviewed and the pathological changes provoked by them, both dermatologic and respiratory, are presented. According to their nature the pathological formaldehyde effects are divided into toxic, allergic, mutagenic and carcinogenic
