ACUTE ORAL LD50 :       (rat)             >6.8 g/kg

ACUTE DERMAL LD50 :     (rabbit)          >2.7 g/kg

ACUTE INHALATION LC50 : (rat)             4479 ppm

PRIMARY SKIN IRRITATION:(rabbit)          non-irritating

PRIMARY EYE IRRITATION: (rabbit)          non-irritating





A 28-day range-finding inhalation study was conducted in male and

female Sprague-Dawley rats exposed to 0, 100, 250, 500, or 1000 ppm

for 6 hr/day, 5 days/week. Clinical signs included increased activity

at 250 ppm and above. Liver and kidney weights were increased.

Microscopic changes in male kidneys stained positive for alpha-2-U

globulin and the effects were considered not relevant to humans. Liver

cell hypertrophy was seen at all exposures in males. Liver changes

were consistent with clinical chemistry and PCBTF-blood level analysis

and are believed to be an adaptive response, due to increased liver

metabolism.



Gavage studies in laboratory rodents for treatment periods of 14, 28,

and 90 days have demonstrated significant liver and kidney toxicity at

dose levels of 400- 1000 mg/kg/day. Evidence of target organ toxicity

included significant increases in relative liver and kidney weights,

clinical chemistry values and histopathological findings. Renal

toxicity which occurred only in male rats, was apparently due to

"hyaline droplet" nephropathy and is therefore, highly unlikely to

develop in man. The NOAEL's for all these studies range from 10 to 100

mg/kg/day.



CNS effects were observed in rats exposed to PCBTF at or above 2822

ppm for 4 hours.



A 90 day(13 week} rat inhalation toxicity and neurobehavioral study

was conducted using exposures of 6 hrs/day, 5 days/week at

concentrations of 0, 10, 50 and 250 ppm. There were no PCBTF-related macroscopic

observations. Microscopically, PCBTF-related centrilobular hypertrophy was

present only in the livers of males and females at the high dose (250 ppm} after

13-weeks of exposure. No centrilobular hypertrophy was observed at any level

among recovery animals. There were no PCBTF-related effects on the nervous

system as measured by a functional observation battery, muscular activity

measurements and neuropathology. A NOEL of 50 ppm was established in this study

for liver hepatocyte hypertrophy in male and female rats. If the hepatocyte

hypertrophy observed is considered to be an adaptive response to PCBTF, the

NOAEL for this study is 250ppm.

p-Chlorobenzotrifluoride (PCBTF) will preferentially partition to the

atmosphere, due to its high volatility. It has been estimated that

99.93% of a 100 Kg spill would end up in the atmosphere, while only

0.06% would partition to water (M. Garlanda, 1990) .The aqueous

solubility of PCBTF (29.1 mg/L) would also tend to limit its potential

impact to exposed aquatic systems. PCBTF has exhibited significant

toxicity to aquatic species under laboratory conditions, but is

unlikely to exhibit a similar degree of acute toxicity under environmental

conditions due to the aforementioned solubility and volatility issues. The

moderate level of bioaccumulation measured in laboratory tests will also be

subject to environmental mitigation due to PCBTF's physical/chemical properties.

PCBTF should rapidly volatilize from dry and moist soils. Volatility, and

relative environmental partitioning characteristics, make it unlikely that

PCBTF represents a significant threat to aquatic or terrestrial

environments.
