Data for substantiating the maximum allowable concentration for aniline
Materialy po obosnovaniju sniženija predel'no dopustimoj koncentracii anilina v vozduhe rabočej zony [in Russian]
Fifty-eight employees in a diphenylamine-production plant were observed for a year; the aniline concentration was monitored and it was found that over a 6-year period this concentration was below the Soviet MAC of 3mg/m3. The majority of the exposed workers presented neurological changes (vegetative disorders, disturbed conditioned reflexes and changes in vibration sensitivity, deviations in temporal artery pressure). 51% of exposed workers presented vegetative vascular dystonia or neurasthenia (in comparison with 27.2% in a control group). The main laboratory findings are tabulated. Long-term animal experiments with 3mg/m3 aniline also indicated the harmfulness of this concentration. The threshold value for chronic aniline poisoning was found to be 0.3mg/m3, and the authors recommend that the Soviet MAC should be reduced to 0.1mg/m3.
