A single sideofthe bag chow sample from Covance was determined to be of significantly higher contamination than the samples from NTH. Because contaminants were found, air and airborne particle and wipe samples were collected on site by the 3M Environmental Lab Field Group. So that results could be based on more than a single sample, additional bags of chow from Covance and Vendor B were also analyzed and are reported in this summary. In the chow samples, 2-(N-ethylperfluorooctanesulfonamido)-cthyl alcohol (EtFOSE-OH) was quantitated by GCMS. EtFOSE-OH was not present above the detection limit of 1 ng/g chow in the triplicate analyzed samples from three Covance bags (labeled meals for June 9, June 15, and June 21, respectively) or from the single Vendor B bag. Triplicate chow samples have not been analyzed for PFOS. Air and airborne particle samples were collected at Covance by Jim Wolter and Kurt Oldenburg of the 3M Environmental Lab Field Group. Air was passed through charcoal and glass fiber filers. Detailsofthe sampling procedure can be found in a report by Jim Wolter and Kurt Oldenburg. The largest volume air samples from the backs of rooms were collected on glass fiber filers and analyzed while samples from the front of each room were collected on charcoal and analyzed. Wipe samples from all rat backs were analyzed but wipes from cages, doorhandes, and floors were not. In air samples taken from Room 3045, EXFOSE-OH was detectedby HPLC/ESMS at levels below the practical quantitation limit (approximately 0.17 ppb/L) but above the method detection limit (approximately 002 ppbL) in some samples. Perfluorooctanesulfonate (PFOS) was not detected at levels above the blanks in any room. Analysis of wipes from the backs of rats in Room 3045 contained a measurable amount of E(FOSE-OH, whereas wipes from rats in other rooms did not. Due to variations in sampling technique, wipe samples were not quantifiable. Wipes from animal backs were not analyzed for PFOS.
