The
use of high doses increases the likelihood that potentially
significant toxic effects will be identified. Findings of
adverse effects in any one species do not necessarily indicate
such effects might be generated in humans. From a conservative
risk assessment perspective however, adverse findings in
animal species are assumed to represent potential effects
in humans, unless convincing evidence of species specificity
is available.

D. M., "Fluazifop-butyl: 55 week oral toxicity study in beagle
dogs," Life Science Research, Stock, Essex, England, 10/15/82.
LSR Report No. 81/ILK019/620. Six dogs/sex/group were dosed for
55 weeks with Fluazifop-butyl, 99.6% purity, by gelatin capsules
at dose levels of 0, 5, 25, and 125 mg/kg/day in a chronic study.
Test article within capsules was dissolved in 0.4 ml/kg corn oil
vehicle. NOEL = 5 mg/kg/day... All
other noteworthy findings were limited to the high dose group,
as follows. Seven 125 mg/kg/day dogs (5 M, 2 F) were killed in
extremis prior to term, generally after at least 29 weeks on study.
Fluazifop-butyl caused ulcerations in the
g.i. tract, specifically in the tongue, lip, mouth lining, stomach
pylorus, or cecum. Ulcerations may have contributed to
low RBC parameters in both sexes (reduced HCT, Hb levels, and
RBC counts, particularly in males)...

Fluosilicic
acid - Wood Preservative
- CAS No. 16961-83-4
-- Rats, oral; 430
mg/ kg (LD 50 ; 2.98 mmol/ kg); Somnolence and/ or general depressed
activity was observed. RTECS* (2000)
-- Rats, Sprague- Dawley albino, oral (via stomach tube); single
doses of 215, 464, 1000, and 2100 mg/ kg (1.49, 3.22, 6.939, and
14.57 mmol/ kg) dissolved in water. Animals were observed for
14 days and then necropsied. With 464 mg/ kg, 3 out of 5 rats
died; at ¥ 1000 mg/ kg, 100% mortality was observed. At ¥ 464
mg/ kg, acute depression was observed. Necropsy showed that animals
in the low- dose group were "grossly normal" and that dead rats
had massive hemorrhages in the entire gastrointestinal
tract. Rhone- Poulenc Inc. (1971)

Fluorouracil
- Former
insect Chemosterilant; now used as a pharmaceutical -
CAS No. 51-21-8
A major use of fluorouracil
is in the palliative treatment of carcinoma of the colon, rectum,
breast, stomach, and pancreas that is not amenable to surgery
or irradiation. The major toxic effects of fluorouracil are on
the normal, rapidly proliferating tissues particularly of the
bone marrow and lining of the gastrointestinal tract. Leukopenia,
predominantly of the granulocytopenic type, thrombocytopenia,
and anemia occur commonly with intravenous fluorouracil therapy
at doses ranging from 6 to 12 mg/kg. Pancytopenia and agranulocytosis
also have occurred.

POTENTIAL
ADVERSE EFFECTS ON FETUS: Exposure in first trimester resulted
in skeletal abnormalities; hypoplasia of aorta, lungs, thymus,
and gastrointestinal tract; and urinary
tract abnormalities. Fetus exposed in third trimester had cyanosis
and clonus.

Tetraconazole
- Fungicide - CAS No. 112281-77-3
Metbolism nd Toxicokinetics. Tetraconazole
was broadly distributed to all organs and tissues tested, with
the highest level detected in the liver, followed by kidneys,
gonads, brain and bones. Low residual levels
were still detected in the liver and gastrointestinal
tract (sometimes bones) at 72 hr.

Triflusulfuron-methyl
- Herbicide
- CAS No. 126535-15-7
Groups of 20 artificially
inseminated female rabbits were treated by gavage with 0, 15,
90, 270 or 800 mg/kg bw/d DPX-66037-24 (95.6% purity) on days
7Ð19 of gestation. The NOEL for maternal toxicity was 15 mg/kg
bw/d. At 90 mg/kg bw, body-weight gains were lower than controls
at the beginning of the treatment period. Clinical signs of toxicity
were observed at 270 mg/kg bw/d (stool absent or reduced, small
stool), abortions and evidence of gastrointestinal
effects were found at gross necropsy (ulceration
of gastric mucosa, gaseous distension). Food consumption
was also lower than controls in the 270 and 800 mg/kg bw/d groups...
