At the terminationofthe study, all animals were humanely euthanized by CO; asphyxiation and necropsies were performed. Blood serum was collected from one animal/time point of the toxicokinetic group sacrificed at PFOS levels day1, day 6, and by high-pressure at day liquid 14 post exposure for PFOS analysis. Analysis chromatography/tandem electrospray mass of spectroscopy (HPLC-MS/MS) was performed according to published methods (3). ext`rSaeanrudmcqufatrnotmeiftihdeedrabtysLacCr/ifMiSce/dMdSabyasoneedpoonstadPoFseOS(Asnimtala#cRnu0r1vd4e6ea8xt)rrwacatsdediniftriaolmly urine collected from the limit toxicity study in rats (T-7098.3).

Necropsy findings and the histopathology report by Dr. Elden Lamprecht, 3M Surgicaland Histopathology Services, is found in Appendix 1. All ra lungs (both control and treated groups) had mild to moderate congestion of alveoli with occasional `extravasation of blood around arterioles and bronchioles.
