## OPTIONAL POLLUTION PREVENTION INFORMATIO N To claim information in the following section as confidential circle or bracket the specific information that you claim as con fi dential . In this section you may provide information not reported elsewhere in this form regarding your efforts to reduce or minimize potential risks associated with activities surrounding manufacturing, processing, use and disposal of the PMN substance . Please include new information pertinent to pollution prevention, including source reduction, recycling activities and safer processes or products available due to the new chemical substance . Source reduction includes the reduction in the amount or toxicity of chemical wastes by technological modification, process and procedure modification, product reformulation, raw materials substitution, and/or inventory control . Recycling refers to the reclamation of useful chemical components from wastes that would otherwise be treated or released as air emissions or water discharges, or land disposal . Descriptions of pollution prevention, source reduction and recycling should emphasize potential risk reduction subsequent to compliance with existing regulatory requirements and can be either quantitative or qualitative . The EPA is interested in the information to assess overall net reductions in toxicity or environmental releases and exposures, not the shifting of risks to other environmental media or nonenvironmental areas (e .g ., occupational or consumer exposure) . In addition, information on the relative cost or performance characteristics of the PMN substance to potential alternatives may be provided
. All information provided in this section will be taken into consideration during the review of this substance . See PMN Instructions Manual and Pollution Prevention Guidance manual for guidance and examples .

### TEST MATERIAL Chemical Name : 1-Bromo-2,2-difluoroethane Physical State : liqui d Sample Reference : CAS # : 359-07- 9 A sample of 1-Bromo-2,2-difluoroethane was submitted b y for evaluation of acute oral and dermal toxicity, and skin and eye irritation . 

## METHODS AND RESULT S In the acute oral toxicity test, three fasted female Fischer 344 rats received 500 mg/kg of test material as a 20% mixture in distilled water by single dose gavage . All rats were normal throughout the duration of the study . All of the rats gained weight during the study . Body weight data are summarized in Table 1
. Three fasted female Fischer 344 rats received 2000 mg/kg of neat test material by single dose gavage . Clinical signs consisted of various combinations of salivation, perineal urine soiling, decreased activity, and incoordination . All clinical signs were resolved by test day 3, and no further clinical signs were observed throughout the duration of the study . All of the rats gained weight during the study . Body weight data are summarized in Table 1 . Therefore, under the conditions of this study, the LD50 for female Fischer 344 rats was greater than 2000 mg/kg
. In the skin irritation test, one male and one female rabbit were dosed with 0 .5 ml of neat test material under an occluded wrap for four hours . The backs of the rabbits were clipped with an electric clipper approximately 24 hours prior to test initiation . The animals were bandaged for 4 hours after application of the test material to provide occlusion and prevent grooming of the application site . Four hours after application, the bandages were removed and the application sites were wiped with a damp disposable towel to remove any residual test substance . The application sites were graded and neither rabbit had signs of skin irritation throughout the study period . The test was terminated after 72 hours . There was no effect on the body weights . Body weight and skin irritation data are summarized in Table 2
. The eye irritation test included instillation of 0 .1 ml of neat test material into each conjunctival sac of one male New Zealand White rabbit that had been screened for ocular defects and irritation 24 hours prior to dosing . The right eye was dosed and washed out after approximately 30 seconds . The left eye was dosed and not washed for approximately 1 hour . An ocular anesthetic was administered to both eyes after moderate discomfort was observed in the right eye

### Slight conjunctivitis was noted in both eyes immediately after dosing . One hour after dosing, the left eye had slight conjunctivitis and the right eye had moderate conjunctivitis . The ocular irritation diminished over time . The conjunctivitis in the left eye was resolved by 48 hours, and the conjunctivitis of the right eye was resolved 7 days after dosing . The test was terminated at this time . Body weight data are summarized in Table 3
. In the acute dermal toxicity test, rats had their trunk clipped 24 hours prior to dosing . A single application of 2000 mg/kg of the neat test material was applied for 24 hours under a gauze patch to the backs of three female Fischer 344 rats . The gauze patch was covered with elastic wrap and tape . Residual test material was wiped off with a damp disposable towel when the bandage was removed 24 hours after application . All animals survived the test period . Two rats had re d periocular soiling and lacrimation on test day 2 . No further clinical signs were observed throughout the duration of the study . All rats given 2000 mg/kg gained or maintained body weight during the study . The data for the individual rabbits are presented in Table 4 . Therefore, under the conditions of this study, the estimated acute dermal LD50 for female Fischer 344 rats was greater than 2000 mg/kg .
