Toluene exposure also changes sleep patterns in animals. Both single 4- or 8-hour episodes of toluene exposure (900-4,000 ppm) and repeated exposures, 8 hours/day for 3 weeks (900 and 2,700 ppm), changed patterns of sleep and wakefulness in rats (Arito et al. 1988; Takeuchi and Hisanaga 1977). After the single exposures, there was a decrease.
