Warner - 1250 G. J. Levinskas - G2WF P. R. Michael - N1E Attached is a summary of the statistical analyses performed on the data from Beverly turner's report "PCB Content of Monkey Tissue," M0A-041, May 7, 1979. This Information may be used as a section of any further reports by MRC or DMEH, or as a starting point for additional statistical analysis as needed. JOH :bjs attachment IN 10 *iV .??> HONS 022370 Statistical Analysis of PCB Content of Monkey Tissue introduction This report covers the statistical analysis of analytical data collected from a subacute feeding study on the concentrative effects of polychlori nated biphenyls on adult Rhesus monkeys and their offspring. (Report M0A-041, "PCB Content of Monkey Tissue" - Beverly J. Hamer, 7 May 1979). The following description of the study is the introduction from that report. "This study is designed to determine the concentrative effects of poly chlorinated biphenyl (PCB) compounds in a subacute feeding program in volving forty-eight adult Rhesus monkeys and their subsequent offspring. The Rhesus monkeys were fed Aroclor 1254 (a PCB compound composed of 12 carbon atoms and 541 chlorine per PCB molecule) as a supplement to their diet. The feeding study was conducted by Litton Blonetics, Kensington, Maryland, for a period of one year. Fat tissue biopsies of the adult animals were taken by the Litton Laboratory and shipped to MRC for the analysis of PCB content periodically during the feeding study (approxi mately every two months) and during an eight-month relaxation period following the feeding study. In addition to the adult fat samples analyzed, numerous Infant skin and fat samples, and colostrum (milk), placenta, and blood serum samples were analyzed on an Intermittent basis. At the termination of the project, liver biopsies were also provided for all adult animals and several Infants. In all, In excess of seven hundred Individual analyses were performed for PCB by various extraction techniques followed by electron capture gas chromatography (EC-GC). The analysis technl ques utilized and the data accumulated are presented in the following sections of this report." The statistical analysis centers primarily on the adult fat and adult liver samples which had relatively complete and well-balanced data. No samples were excluded. Data were not complete for the baby skin, baby fat and milk samples, but these are presented for Inspection, with statistical analyses where applicable. All the data treated were assumed to be log-normally distributed, and averages and confidence limits were calculated on this basis and converted back to the original scale. SUMMARY OF RESULTS Adult Fat Samples (male and female) PCB level In adult fat samples for animals fed the highest amount of PCB is significantly higher than control from one month through 20 months. Average PCB In tissues for this period Is 28.2 PPM (wet weight basis) and 53.5 PPM (lipid weight basis). MOMS 022371 S-81-SS-2 Page 2 PCB level In adult fat samples for animals fed the medium level of PCB is significantly higher than control from 4 months through 20 months. Average PCB in tissues for this period is 13.2 PPM (wet weight basis) and 20.5 PPM (lipid weight basis). PCB level in adult fat samples for animals fed the low level of PCB is significantly higher than control from 7 months through 20 months. Average PCB in tissues for this period is 2.8 PPM (wet weight basis) and 4.2 ppm (1ipid weight basis). PCB level In adult fat samples for control animals (no PCB fed) averaged 0.30 PPM (wet weight basis) and O.SS PPM (lipid weight basis) for the period from 1 to 20 months. Adult liver Samples - 20 Months (male and female) PCB level in adult liver samples increased in proportion to the amount fed. On a wet weight basis, the control samples averaged 0.076 PPM, low level samples averaged 0.4 PPM. medium level samples 0.81 PW and high level samples 2.43 PPM. 'On a lipid weight basis, these results were 2.2 PPM, 10 PPM, 23 PPM and 7S PPM respectively. Baby Skin Samples PCB levels found in baby skin samples Increased with Increasing PCB in parents' diet, and with sampling time up to 7/31/78 (insufficient data for statistical analyses). Bibv Fat Samples PCB levels found In baby fat samples increased with increasing PCB In parents' diet, and with sampling time up to 7/31/78 (Insufficient data for statistical analysis). Milk Samples There was a significant Increase of PCBs In milk as a function of the PCB level In the feed. The data were too widely scattered to determine what kind of model best fit the data. The linear model gave the following equation: Amt. PCB In milk 0.094 0.0097 (amt. PCB fed). The correlation coefficient was 0.92, significant at 99.9t P<0.001. DESCRIPTION OF STATISTICAL APPROACH Adult Fat Samples - Met Height and Lipid Height Basis Table I shows the output from a computer program which calculates the 951 confidence limits of the mean of the amount PCB found In the adult fat samples. The program converts the data to logarithms, calculates the mean HONS 022372 S-81-SS-2 Page 3 and standard deviation of PCS found for each level fed at each sampling time, then calculates 95X confidence limits of the means of the logarithms. This information is converted back to PPM, and 95* confidence limits of the mean are reported In PPM and as percent of the mean. [t Table II Is a summary of the averages by month for each level of PCS fed. Table III gives specific statistical conclusions by month. Figures la and lb are composite plots of the means and 95* confidence limits of PCD found for each level fed vs. sampling time. The test for significance was based on the degree to which the 95* confidence limits of the means overlapped. The least significant difference (95* level) between the means Is approximately 2.828 standard deviations, tlien there is no overlap of the 95* confidence limits, the means are approximately 4 standard deviations apart. The Individual comparisons can be confirmed using Students' t test. Adult Liver Samples - End of Study The procedure for calculating confidence limits of the means is the same as In Adult Fat Samples. Figures 2a and 2b show the means and confidence limits of the means for PCEs found at each level of PCB fed. Least squares lines were determined for the average PC8s found vs. amount PCB fed. For lipid weight samples PPM found (lipid) * 4.6 + 0.21 (PPM In feed). For wet weight samples PPM found (wet) 0.20 + 0.022 (PPM in feed). Both these equations were significant at 99.9* (p<0-001) Baby Skin Samples Table IV shows average PPM found on wet weight basis In baby skin as related to level fed to parents, and sampling time. Lipid weight results are not shown because of extreme variation In lipid weight to sample weight ratio. Babv Fat Samples Table IV shows average PPM on wet basis, presented as Indicated In paragraph under Adult Fat Samples. Milk Samples Table V shows the average PPM found In milk samples, presented as related to PCBs consumed. HONS 022373 S-81-SS-2 Page 4 discussion The foregoing analysis of the data Is an attempt to describe the effects of various levels of PCB in the diet on the resulting amount of PCB found In the animal tissues. No attempt was made to fit any sort of theoretical model, but the adult fat data may be sufficiently consistent to support such an approach. In addition, we have not tried to relate PCB levels to toxicology data, but recommend that this be done when the latter are available. ACKNOWLEDGMENT The assistance of J. L. Davis (Environmental Sciences) in running the computer calculations of means and confidence limits is gratefully appreciated.
