EC number: 205-572-7
CAS number: 142-92-7
Effects (acute, transient signs of reduced activity levels, decreased
body weight and feed consumption, signs of upper respiratory tract
irritation in the nasal passages) were only observed in the high- (3000
ppm) and mid-concentration (1500 ppm) group; there was no systemic,
The mean time weighted analytical exposure concentration for the 500 ppm
(2.4 mg/L) group was 548 ppm (2.6 mg/L))
Repeated exposure to n-butyl acetate for 6 hours per day for five days a
week for 13 weeks at concentrations of 500, 1500 or 3000 ppm resulted in
acute, transient signs of reduced activity levels during exposure to
1500 and 3000 ppm. Decreased body weight and feed consumption were noted
for the 1500 and 3000 ppm groups, but there was no systemic or
organ-specific toxicity. Signs of upper respiratory tract irritation
were seen in the nasal passages of 1500 and 3000 ppm animals, but there
was no evidence of pulmonary toxicity.
The effects following the first single exposure were similar to effects
observed in the subsequent days, no specific effects of acute exposure
were identifiable from this data set.
The acute LC50 is therefore estimated to be >3000ppm (15.3 mg/L).
