Review and Audit of XBT No. 663-03222, Chronic Vapor Inhalation Toxicity Study with Vinyl Chloride (Ethylene Derived) in Albino Rats, Albino Mice and Golden Hamsters ^or the"ManufactnringChemists Association
The review and audit of this study was conducted at IST's offices in Northbrook, IX., April 14 to April 18, 1980. 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 written, 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.

1973 from Or. Torkelson of Dow reflects a site visit was
made by the MCA. Task Force, visiting the Decatur research
labs of IBT where the study was conducted. 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. Band
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, 90USING 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.
Bowever, 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.

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, 8 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 scene of the animals in the racks reflect the animals excaped or were cannibalized, along with mortality dates for the remain ing individual animals.

VINYL CHLORIDE, SOURCE, IDENTITY Vinyl chloride (ethylene based) appears to have been
supplied as, e.g., containers in excess of 500 pounds, by PPG Industries, Industrial Chemical Division, Lake Charles, LA. A letter from W. B. Sraybill 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 BioTest. 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. Unfortunately, we were unable to find a daily log for

the weighing or measuring of the vinyl chloride that was dispensed during each daily run. 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. There 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.

1. Most of the time the chambers were not on for six hours. 2. Most of the time the chambers were not even monitored
for five hours, in some instances they were only moni tored for one to two hours. 3. In some instances there was selected data for the daily exposure concentration, e.g., values on the low side may have been eliminated or values on the high side may have been eliminated. 4. Periodicallyr there were mechanical problems associated with the rotometer, e.g., broken or clogged or unclean lines. 5. Some days there was no exposure because of equipment failure or TV filming or only a one-hour exposure was conducted. 6. There was evidence that the chambers did not have an adequate clearance time, since measurements made 45 minutes after termination of the exposure still showed rather high levels of vinyl chloride present. 7. There was evidence of contamination in the solvents room and the pilot plant which were in close proximity to the exposure room. 8. Some days there was no analytical data recorded for the exposure concentrations. 9. In some cases, the research log book showed means and ranges for exposure concentrations, with no raw supportive

data shown for periodic sampling with the gas chromato graph. 10. In some instances/ the 50 ppm nominal concentration may have reached a concentration as high as 100 ppm and, in one instance, as high as 400 ppm which is not reflected in the means or ranges presented in the interim report. 11. In some instances, the control chamber indicated levels of vinyl chloride in a range of 5-11.5 ppm. 12. In September of 1974, near the end of the year of expos ure, there was some research book data reflecting exposure concentrations but no supportive gas chromato graphic data. 13. In some cases there is no data available for one or two levels out of the four exposure chambers being run. 14. There were periodic problems with the gas chromatograph itself, either with the Ignitor, Detector or the Recorder. 15. In some instances there were means and ranges presented in the research book but no interval data were available. 16. In some instances, the chamber may have been on for four or five hours yet gas chromatographic readings were only taken for two hours. 17. There were a number of instances where the data presented in the research book do not agree with the data shown on the gas chromatographic chart.

Specific Exposure Observations The following notations were associated with:the spe
cific exposures and may also be used together with the inhalation chamber concentrations presented in Table I. The exposure concentrations presented in Table I are those presented by IBT and one can see with the use of these spe cific notations that the values presented in Table I are not an accurate reflection/ in many instances/ of the exposure concentrations or are based on minimal supportive analytical data.

COTnmen-t There are no T-I or T-XI data on the chart or in the book. T-III data is present in the research book but not on the gas chromatographic chart. The gas chromatographic chart and the data in the research book agree but the exposure concentra tions are on the low side. The gas chromatographic charts do not match the data in the log book. Observations were noted that some of the data was off the GC chart and there were some operator errors and missing data. There were no GC charts to go with the data pre sented in the research books. No charts available for the exposures 110-136. A line was drawn through the first hour values and apparently discarded. There are gas chromatographic charts and research book data available but another notebook says that exposures were not run. In addition, the control line shows contamination. A notation was made that some of the readings were off the chart -- wide excursions on both the low and high sides. In addition, the controls were contaminated.

The solvent room and the pilot plant both showed vinyl chloride contamination. The first reading on the gas chromatographic chart is 3:55 pm. The readings continue until 4:40 pm at sharply lower concentration. The chamber was turned on at 10 o'clock in the morn ing. Sampling was only conducted for 4 hours. The T-IXI value was 3710 ppm. For the T-I and T-II lines, there was no sample taken, for the second sampling interval or the fourth interval. Basically no analytical data on exposure concen tration . Exposures were sampled far five hours. Selected data in the daily range and no noon samples. The control line was contaminated. The chambers ran for five hours and GC data are available for three.

Comment_____________________ A seven-hour exposure is indicated as having been run. The sampling for GC analysis was run for somewhat less than five hours. Selected data has been taken at the initial reading and then spor adic data is missing throughout the run. The chambers were not monitored and no data are available. No sampling. Exposures were only on for one hour with a notation of TV filming. There was one reading for each line for the first two hours, obtained manually. Half of the samp lings were done on automatic, but two, rather than three, samples were obtained. Notation is made of CBS filming tomorrow; expos ures were run for 4 1/2 hours. The line control had a reading of 6. The GC chart shows no agree ment with the research book, which is sparse. However, it does show T-IJI range from 3-320 ppm. The T-I 50 ppm range equals 445 ppm. No gas chromatographic charts to support the mini mal data in the research book. The chambers were turned on at 9:00 am and were off at 11:40 am-.i GC readings were taken only at 10:00 and 11:00 am.

One-third of the values which were on the low side were deleted from the calculation of the averages, one of which was off the graph. Se lected data is shown. The control shows a peak height of 7.5, indicating some contamination. The gas chromatograph was not working; no data but means have been reported for one value at one interval. The research book shows a mean and ranges but no supportive data-were available. The line control shows a peak height of 8. Onethird of the data from the GC charts were not used in the calculations or averages in the research book. Samples are only shown for three hours. The GC chart data is sparse.

BODY WEIGHTS Body weights were available, either as hand written
calculations or as computer printouts. Unfortunately, many of the computer printout body weight tabulations reflected the animals being weighed on a gang-cage basis. Therefore, it becomes more difficult to determine substitutions. A tabulation beginning with month 5 and proceeding through month 13 is shown below for the body weight data. This com pares the data presented in the interim IBT reports versus that obtained when one inspects the computer printout itself. These data have only been examined for the T-III group.

MORTALITY AND FATE Band written sheets reflecting tabulations of mortali
ties are available. These sheets bear various dates at periodic intervals. Additional tabulation reflects animals that are missing or cannibalized, based upon the gang hous ing. However, there are numerous errors present and inconsis tencies in these tabulations. A chart of missing rats, pre pared near the end of the third month of the study, shows numerous animals not accounted for in Dr. Shah's tabulation. These differences are as follows:
Untreated control male rats - 2 animals missing; none shown on Dr. Shah's tabulation.
Untreated control females - 3 missing; none shown on Dr. Shah's tabulation.
T-I male rats - 7 missing; 1 shown on Dr. Shah's tabulation. T-1I male rats - 6 missing; none shown on Dr. Shah's tab ulation. T-XXI male rats - 4 missing; none shown on Dr. Shah's tab ulation . T-l female rats - 6 missing; none shown on Dr. Shah's tabulation. T-XX female rats - 2 missing; none shown on Dr. Shah's tab ulation* T--III female rats - 4-5 missing; none shown on Dr. Shah's tabulation.

I There are numerous evidences of errors in the animal numbers or the animals being missexed, e.g., animal 751 female should be 638 male in the T-III group; animal 787 female should be male 691 in the T-III group; animal 788 female should be 692 male in the T-III group; animal 689, T-III male rat should be 686; 605, T-III female rat, is a male. 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. You will note a sub stantial difference in the numbers available as tabulated between the printout and that presented in the report for the male T-III group, month 7, 12 and 13. 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.

I Animal #641, T-IIX male, was found dead at 369 days, according to the report. Band 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.

CON CLP51ONS An intensive audit of certain aspects of IBT No. 633-03222,
chronic vapor inhalation toxicity study with vinyl chloride, devoted to inspection of exposure concentrations and pertin ent body weight and mortality logs Indicates the following: (a) There are numerous evidences of replacement of animals
in this study. 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-XII 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-XI level were relatively infrequent and there do not appear
BOB WEST ASSOC IATES. INC.
IBT No. 633-03222
to be any real instances of overlap between the T-II and T-III 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.
