The purpose o f this supplemental notice is to summarize recent 3M studies conducted to determine whether perfluorooctanesulfonate (PFOS) ion can be detected in tissue sam ples from different animal species.1 These studies w ere designed to obtain initial screening data on the distribution o f PFOS in biota. Sam ples within each study w ere extracted and analyzed using high-performance liquid chromatography-tandem mass spectrometry (HPLC-ESMSMS). The analytical methods used in "Study 1" (eagle and albatross) and "Study 2" (eagle) w ere still being optim ized at the tim e o f data collection; the results are understood to be accurate to +/-50% . "Study 3" (w ild bird livers study), below w as conducted using more refined analytical methods that provide accuracy for PFOS determination to +/-30% . Although all o f these studies involve a limited number o f samples, w e are providing the results so that EPA can place in context existing know ledge regarding the presence o f PFOS in different biological receptors. S tu d y I : S creen in g o f P F O S le v e l s in E a g les a n d A lb a tro ss. Five samples o f plasma from eagles and albatross w ere analyzed. Three o f the five eagles were less than 250 days old; the age o f the remaining tw o birds are unknown. The eagles were obtained from Northern M innesota and M ichigan; the albatross were obtained from M idw ay Island in the Pacific. PFOS w as detected in each o f the five sam ples o f eagle plasma at levels o f 30, 34, 77, 31 and 34 ppb. Three out o f the fiv e albatross samples did not contain PFOS above the limit o f detection (1 0 ppb). D etectable, but not quantifiable, levels o f PFOS were detected in the remaining tw o samples, both collected from birds under 1 year old. A s only a small amount (less than 1ML) o f plasm a w as available for analysis, it was not possible to conduct matrix spike analyses.1 1These studies also include measurements o f other non-PFOS compounds, but these FCs have not been fully quantitated. 3M M N01329658 US Environmental Protection Agency May 26, 1999 Page 2 27-CV-10-28862 Filed in Fourth Judicial District Court 11/17/2017 7:15 PM Hennepin County, MN Data collected in support o f this study is o f semi-quantitative screening quality with a margin o f error estimated to be + /- 50%. S tu dy 2: A n a lysis o f E x tra cts R e p o rte d in E a e le s. Extracts from three sam ples o f sea eagle plasma (collected from the Baltic Sea) and seven samples o f bald eagle plasma (collected from North Am erica) w ere analyzed quantitatively for PFOS. The target analyte w as detected in all o f the eagle plasm a sam ples screened. L evels in sea eagle plasma sam ples w ere 125, 93, and 215 ppb; levels in bald eagle plasma w ere 165, 198, 494, 1047, 226, 371 and 375 ppb. All birds except for the o n e at 1047 ppb w ere less than 1 year old. Data collected in support o f this study is o f semi-quantitative screening quality with a margin o f error estimated to be + /- 50%. Only 2 (250 ppb) PFOS matrix spike sam ples w ere extracted and analyzed. S tu dy 3: A n alysis o f F lu oroch em icals in W ild B ird L ivers. Sixty liver samples collected from various species o f birds were characterized with respect to PFOS. The birds were classified according to species and geographic location. Six species o f birds w ere represented in this study, including Sandhill Cranes, Double-Crested Cormorants, White Pelicans, Brown Pelicans, Great B lu e Herons, and Brandt's Cormorants. The birds w ere found at a variety o f sites across the United States including Nebraska, N ew M exico, Florida, Arizona, California, Louisiana, and Florida. In general, the cause o f death to these birds is unknown. Although only minimal spike recovery studies were conducted, this data was collected using methods that have been fully validated on a related matrix. The data for PFOS is semi-quantitative screening data with a margin o f error estimated to be +/-30% .

Therefore, 3M is in the process o f implementing a more com prehensive program o f sampling and analysis to quantify PFOS levels across a range o f species, environmental media and geographic locations. These additional data will provide a fuller basis for characterizing the fate and distribution o f PFOS and other FCs in biota and ecosystem s.
