Abstract
Aniline is an oily colorless liquid with a characteristic odor. It is classified as a substance that exerts toxic effects through inhalation, ingestion and skin. It can cause damage to the eyes and induce allergy by dermal contact. Aniline is produced in large quantities. It is a precursor to obtain transient compounds used in various industrial branches. It is used to produce 4,4’-methylenedianiline, a precursor for obtaining polyurethane foams, and to produce compounds of the industrial rubbers, dyes, pesticides and pharmaceutics. Occupational exposure to aniline may occur during its production, further processing and distribution, during the aniline release in the form of a breakdown product of thermal degradation of plastics (e.g., foundry or industrial rubber vulcanization) and application of aniline-containing products (e.g., dyes). An internal 35-mg dose of aniline corresponds with the velocity of p-aminophenol urinal excretion under 1.5 mg/h in a 2-h collection at the end of work shift (6÷8 h). The maximum allowable concentration in the biological ma-terial for aniline is 1.5 mg of p-aminophenol/h.
