-- Trifluoromethylbenzene
was studied for oral toxicity in Crj:CD (SD) rats in an OECD combined
repeat dose and reproductive/developmental toxicity screening
test at doses of 0, 20, 100 and 500 mg/kg/day... Depression
of body weight gain in offspring of all treatment groups
was observed without any necropsy findings. The NOELs are considered
to be 500 mg/kg/day for reproductive performance of the parents
and less than 20 mg/kg/day for offspring development.

SYMPTOMS: This comound
is extremely destructive to the mucous membranes, upper respiratory
tract, skin and eyes. Inhalation
may be fatal as a result of spasm, inflammation and edema of the
larynx and bronchi; chemical pneumonitis and pulmonary edema.
Other symptoms include a burning sensation, coughing, wheezing,
laryngitis, shortness of breath; headache, nausea and vomiting.

Kidney
(click

-- Trifluoromethylbenzene
was studied for oral toxicity in Crj:CD (SD) rats in an OECD combined
repeat dose and reproductive/developmental toxicity screening
test at doses of 0, 20, 100 and 500 mg/kg/day. With regard to
repeated dose toxicity, effects on liver and kidney
were observed in both sexes given more than 100 mg/kg, indicating
a NOEL is of 20 mg/kg/day for both sexes. In the reproductive/developmental
toxicity study, there were no effects of the test article on the
reproductive performance of the parents. Depression
of body weight gain in offspring of all treatment groups was
observed without any necropsy findings. The NOELs are considered
to be 500 mg/kg/day for reproductive performance of the parents
and less than 20 mg/kg/day for offspring development.
-- Test Results: ... As necropsy findings,
renal hypertrophy and discoloration were observed in males of
the 500 mg/kg group. Increase kidney weights
in males given more than 100 mg/kg and in females of the
500 mg/kg group, and increased liver weights in males given more
than 100 mg/kg were observed. On histopathological examination,
centrilobular hepatocyte hypertrophy in both sexes, and hyaline
droplets, necrosis, basophilic change and dilatation of renal
proximal tubules in males were noted in the 100 and 500
mg/kg groups. Therefore, the NOEL is considered to be 20 mg/kg/day
for both sexes.

Experimental BCF values of 26-54 and 31-58 suggest
that benzotrifluoride will bioconcentrate in aquatic organisms.
-- Environmental Bioconcentration: An estimated BCF value
of 110 was calculated for benzotrifluoride(SRC), using an
experimental log Kow of 3.01(1) and a recommended regression-derived
equation(2). Bioconcentration factors determined from a
six week study in carp using 100 and 10 ug/L benzotrifluoride
were 26-54 and 31-58, respectively(3). According to a classification
scheme(4), these BCF values suggest
that bioconcentration in aquatic organisms will be an important
fate process(SRC).
