Diphenylhydrazine has been assayed but not detected in fish samples from the Great Lakes area. Camanzo et al. (1987) reported that no 1,2-diphenylhydrazine was detected in fish samples from 13 Lake Michigan tributaries and Grand Traverse Bay fish. Analyses were made by GC/MS and no detection limits were given. Similarly, DeVault (1985) reported that a GC/MS did not identify any of the peaks present in fish samples from Great Lakes Harbors and Tributaries as... 

No PBBs were detected in several varieties of fish (carp, white sucker. Northern pike, bullhead, and bass) from the Alma Reservoir, which is upstream from the Michigan Chemical Corporation plant and above a dam that prevents fish from moving upstream (Hesse and Powers 1978). On the other hand, tissue samples from fish collected from the Pine River, 29 miles downstream from the plant, contained up to 1.33 mg PBBs/kg (wet weight in skinless fillets). There was no apparent change in PBB concentrations in fish between 1974 and 1976 (Hesse and Powers 1978). PBBs could be detected in fish from Pine River and other embayments and tributaries of Lake Huron in 1983. PBB concentrations in carp and other sedentary fish from embayments and tributaries of Lake Huron (including Pine River) and Lake Superior were determined (Great Lakes Water Quality Board 1989 Jaffe et al. 1985). PBBs were detected in the concentration range of 15 15,000 g/kg (fat basis) in fish from embayments and tributaries of Lake Huron, but not from Lake Superior. 

In the Great Lakes region, surface water samples were analyzed for PFAs in Lakes Ontario, Erie, and their tributaries, and various Michigan rivers (Table 11). Most reports are for PFOS and PFOA, whereas PFHxS and FOSA are often below method detection limits and no data exists for longer-chain perfluoroalkyl carboxylates. It can be generalized that the concentrations of PFOA slightly exceed the concentrations of PFOS at all background sites.
