ABSTRACT
Male guinea pigs were exposed to 750ppm or l000ppm or 1 500ppm toluene (8h/d, for 14d), and their hearing thresholds were tested by means of Madsen ERA 2250 system 3d and 14d after exposure. Hearing impairment was observed in all groups. The degree of impairment was related to the exposure concentration and had a tendency to further damage in two weeks. The results indicate that toluene can cause acute hearing impairment even if its concentration is as low as 750ppm and the impairment develops from bad to worse at least in two weeks.
