摘要: Descriptive statistics were developed for Hg concentration data 1,103 walleyes (Stizostedion vitreum Mitchill) from 219 Wisconsin lakes of various ANC. Lake means concentrations in skin-on fillets fish total length groups and lake ANC intervals increased as decreased. mean exceeded the Division Health standard 0.5 µg g−1 ww ≽40.0 cm with < 300 µeq L−1, similar to 55.0 64.9 ≽900 L−1. A linear regression model predicting walleye was developed, but only 42% variation explained by model. Individual relationships differed greatly among comparison <300 L−1 northeastern Minnesota, northern Wisconsin, southeastern Ontario indicated that increase west east.
