SUMMARY During the month of September vfiO environmental and research samples have been analyzed for polychlorinated biphenyls (PCB's) by electron capture . gas chromatography. Analysis of these samples represents a minimum man power expenditure of 210 hours. PCB's, typical of our Aroclors, have been found at levels below and above action levels in: . Fish meal, soybean meal and meat meal (animal and poultry fed components) . Paperboard and polyethylene film (food packaging materials) . Environmental samples from three customer sites (oil, sediment, and water) . Two Monsanto products . Fish and sewer effluents from two Monsanto manufacturing sites An over view of the analytical results is shown in Table I in the detail section.

The fairly consistent factor, 2-2.5X between the numbers leads me to believe that they are not extract ing the PCB quantitatively from the meal. Subsequent analyses of four of these samples, spiked at a level equiva lent to that found, indicates that our procedure recoveries were in the range of 100-106%. The actual recoveries are shown in the following table.

The results shown have been corrected for the 0.3 PPB blank. After orally reporting these results to Paul Henry, he indicated that they would not need much more support analysis. Possibly one more set to confirm the low PCB level observed in their 7-15-71 sewer composite sample.

Matrix interferences were encountered which required that a maximum and minimum be reported (Santoquin composite 9-19-71). GC/Mass analysis of the residues extracted from Santoquin verified that if PCB1s are present they would have to be at a level less than 0.5 PPM. Spiking of three samples of Santoquin at the 1 PPM level with A-1242 yielded recoveries of 73%, 92% and 96%. A tentative method will now be written but further research is planned in order to remove EC/GC inter ferences .

As you can see, our analytical results do not reflect the added PCB's. I have talked to A1 Peterson about this apparent discrepancy and it was decided that spiked samples would be included with their August set to see if this problem can be worked out.

The results of each laboratory analysis of these samples are to be compared to insure consistent internal reporting. National Broiler Council Intra-Laboratory PCB Methodology Check Ten sets of soybean oil and chicken fat samples were prepared by Monsanto for distribution by Ralston-Purina to government and industrial laboratories analyzing samples for PCB's. The objective of this intra laboratory check is to establish the validity of the different PCB methods currently being employed. HQNS 057145
