[Exposure to beta-naphthylamine in the Polish industry].

Data on occupational exposure to beta-naphthylamine obtained from Departments of Occupational Hygiene in Sanitary-Epidemiological Stations have been verified. The verification implied that this compound may occur in air only at the production of phenyl-beta-naphthylamine and in few research laboratories where exposure bears no industrial nature. The exposure to beta-naphthylamine at the production of phenyl-beta-naphthylamine was evaluated. The studies demonstrated that beta-naphthylamine occurs in air only at scaling of phenyl-beta-naphthylamine and its concentration does not exceed 0.0024 mg/m3.
