The review and audit on this study concentrated on the con duct and monitoring of the exposures. However, attention was also devoted to the source of the animals and body weight data as they affected fate and mortality. In addi tion, the review and audit included inspection of hand writren observation books reflecting exposure concentrations. as well as gas chromatographic charts where they were avail able, hand written and computer body weight printouts, hand written mortality logs, hand written observations and cor respondence. CORRESPONDENCE, PROTOCOL AND TIMETABLE The timetable indicates the exposures were to be ini tiated on 9/10/73 for the T-I, T-II and T-III groups and on 10/1/73 for the T-IV groups. The termination of the exposures for the first three groups was to be at 9/8/74 and for the T-IV group at 9/27/74. The animals were then to be held for a year prior to terminal sacrifice.

Questions were raised about the adequacy of equipment, the exposures main tained, the exposure concentrations, the question of contam ination and record keeping. A major concern was raised about the adequacy of the analyses and record keeping.1 Hand written notes alongside the margin of this letter indicate that certain corrective actions were taken at IBT. I was unable to tell whether there were any other documented site visits. In addition, a progress report issued October 13, 1973 after about a month of exposure, reflects adjustments that were made to compensate for the issues that were raised during the MCA site visit. ANIMALS, HOUSING AND HUSBANDRY The animals for this study were supplied by the Charles River Breeding Laboratories. Unfortunately, we are not able to identify specific animal receipts with this project. However, we were able to identify from September invoices receipts of hamsters as replacements without charge for ani mals that were dead on arrival in the August shipment. We were able to identify an additional receipt of hamsters in early November, 1973, two months after the study started, which indicated 130 males and 130 females were received at that time.

CMA 010961 I3T No. 633*03222 -3- Inspection of the body weights early in the study in dicates despite the report not reflecting the mortalities that there was a rather high mortality in the hamsters early in the study. At four and five months there were extensive replacements of the hamster groups. The animals were ear punched and the toes removed so the animals could be individually identified. This was to allow for identification for individual body weight determin ation and identification of when the animals died, because the animals were group housed in groups of 3-5 in stainless steel cages. Inspection of some of the hand written notes shows the layout of the rats in the rack and indicates that extra animals were to be spaced evenly throughout the rack. In addition, another hand written sheet shows the arrangement of the gang cages in the chambers. There were 18 gang cages, 3 rats each, to equal 144 rats. However, the protocol only calls for 100 rats at each level. This procedure allows for ample opportunities for replacement and substitution. Despite the fact that the animals were identified by ear punching and toe removal, most of the time the animals were not weighed individually but rather by the cage, e.g., 3-5 animals. Numerous hand written notes showing the arrangement of some of the animals in the racks reflect the animals excaped or were cannibalized, along with mortality dates for the remain ing individual animals.

A letter from W. B. Braybill of PPG to Dr. John Goode of Bio-Test in Decatur indicates that one cylinder would be required per month. Heel sample analyses from the Bio-Test residues were also performed by PPG at the Lake Charles, LA operation and those that were available appeared to be in good agreement with the new sample analyses supplied to Bio- Test. Unfortunately, there was no inventory log at IBT for vinyl chloride. PPG personnel should be asked for account ability of the vinyl chloride sent to IBT. In addition, they would also have records of the returns for heel analyses. GENERATION OF VINYL CHLORIDE VAPORS The vinyl chloride supply tanks were kept in an explos ion room. The material was piped to the test chambers through thin-walled stainless steel tubing. Before the thin-walled tubing delivered the vinyl chloride to the chambers, it was connected to a micrometering valve and a glass rotometer to control and monitor the supply of vapor to each chamber. Vapor-air mixture entered the top of the inhalation chamber, circulated through the chamber and was exhausted at the bot tom. CONFIDENT TAT.

CHAMBER MONITORING There are records of standardizations being conducted in September of 1973, covering the range from 20 to 100 ppm standardization and from 50 to 400 ppm for the 200 ppm standardization and from 400-4000 ppm for the 2500 ppm^level. Standardizations were performed at approximately weekly in tervals prior to that point where the automatic sampling system was hooked up to the on-line gas chromatograph record er. The initial samples from the chambers for the first part of the study (six weeks) were obtained by use of grab samples which were then analyzed by the gas chromatograph. We were unable to find any record of daily sample analyses being taken in the research books for the month of October, 1973, the second month of the study, other than ranges and mean concentrations. Thera also was no evidence of chamber temp erature or humidity being recorded. General Observations The following observations were obtained by inspection of research log books which present means and ranges of exposure concentrations, time interval sampling for the gas chromatographic concentrations and charts, as well as the hand written observations in the research log books.

Autopsy sheets that reflect extra animals were avail able. A mortality tabulation prepared from the animals avail able in each group, as determined by the body weight print outs, beginning with month five and continuing through month 13 is shown in the accompanying Table.

Similarly substantial differences in the females in months 12 and 13, as well, also suggests substitution of the animals was occurring. Close attention was paid to determining the specific fate of the five animals examined in detail by Dr. Bussey in the T-III male group, as reported to have brain tumors. Inspection of the hand written post mortem tabulations by IBT staff, as opposed to the data presented on the autopsy sheets and the mortality data presented in the final report indicates substantial discrepancies. ' -- ^0,7 BOB WEST ASSOCIATES. INC. CMA 010976 IBT No. 633-03222 -18- Animal #641, T-III mala, was found dead at 369 days, according to the report. Hand written P.M. tabulation sheet shows the animal to be dead by 8/6/74, which is about 330 days into the study. The necropsy sheet shows the animal's date of death as 9/3/74 (359 days). These differences have not been explained. In the case of animal #649, the necropsy sheet and the report shows that the animal died at 402 days. The sheet presenting post mortem tabulations, dated 9/11/74, however, shows the animal as being dead. This date would be approxi mately one year into the study. Animal #664 was reported as having died at 373 days. This animal is shown as being dead 7/17/74 on the necropsy sheet and as being dead on a hand written tabulation on 8/9/74. Therefore, the 373 day mortality presented in the report is incorrect and was probably 311 days. Animal #672, shown in the report as having died at 310 days, is also shown on a post mortem mortality tabulation dated 7/26/74 as being dead by that time. A necropsy date of 7/16/74 for this animal is noted. Therefore, the fate of this animal appears to be correct. In the case of animal #667, the report, indicates days on test as 383 but the necropsy sheet is dated 6/27/74, re flecting less than a year on test. A post mortem log dated 6/26/74 also shows the animal as being dead. Therefore, the date presented as days on test in the report is in error. CMA 010977 Subject to BOB WEST ASSOCIATES. INC:ggsa v.

There appears to be an exceptionally high replacement of the hamsters. Also, because of the dif ferences in body weights and mortalities noted in the T-III rats, it is possible that there was major substi tution of the animals between the sixth and seventh months of the study and perhaps at 12 and 13 months. There are evidences of extra animals being available for the various species in the study. The accountability for the animals and the mortalities show substantial discrepancies. (b) The monitoring of the exposure concentrations and the conduct of the exposures shows poor technique and selec tion of data in many instances but does seem to indicate that a three-level study was conducted, even though the swings in exposure concentrations periodically may have been t 50-100%. The instances of actual overlap between exposure concentrations at the T-I 'level and the T-II level were relatively infrequent and there do not appear BOB WEST ASSOCIATES. CMA 010978 IBT No. 633-03222 -20- to be any real instances of overlap between the T-li and T-IXI levels. (c) The animals reported to have brain tumors indicate discrepancies as to their actual dates of death versus those reported in interim reports and in some cases on the necropsy sheets. In summary/ the study was conducted in an extremely sloppy fashion and one would have to look at any of the re sults more from a qualitative standpoint than a quantitative standpoint.
