Congener specific PCB distribution in lake trout/siscowets and walleye from the Great Lakes
- Michigan State Univ., East Lansing, MI (United States)
Lean lake trout (Salvelinus namaycush) from Lakes Huron, Michigan and Ontario and siscowets (fat lake trout) from Lake Superior as well as walleye (Stizotedium vitreum vitreum) from Lakes Erie, Huron and Michigan were analyzed for 53 PCB congeners commonly found in Aroclor 1254. The average PCB congener pattern is presented for a minimum of 12 fish from each species from each lake and the distribution of PCB congeners among species and lakes is compared. Greater differences were found for the lake source of the lake trout than for the walleye. Lake trout from Lake Ontario had high levels of congener 198. Lake trout from Lakes Huron and Superior also tended to have higher levels of higher chlorinated congeners while lake trout from Lake Michigan had the highest levels of the lower chlorinated congeners. Fewer lake effect differences were found for distribution of PCB congeners for the walleye. Walleye from Lake Huron had a greater percentage of the total PCB congeners with lower chlorination than did lake trout but the pattern of percent of total for lake trout and walleye from Lake Michigan was quite similar.
