Mercury Levels in Marine and Estuarine Fishes of Florida 1989–2001. 2nd edition revised

The Florida Fish and Wildlife Conservation Commission’s Florida Marine Research Institute (FWC-FMRI) has examined total mercury levels in muscle tissue from a variety of economically and ecologically important species as part of an ongoing study to better understand mercury contamination in marine fishes.The FWC-FMRI Mercury Program is one of the most comprehensive programs in the United States for monitoring mercury levels in marine and estuarine fishes. Because mercury, a toxic metallic element, has been shown to bioaccumulate in fish tissue, humans consuming fish can potentially consume significant levels of mercury.We examined the concentration of total mercury in 6,806 fish, representing 108 species from 40 families. Species represented all major trophic groups, from primary consumers to apex predators.The majority of individuals we examined contained low concentrations of mercury, but concentrations in individual fish varied greatly within and among species. Species with very low mean or median mercury concentrations tended to be planktivores, detritivores, species that feed on invertebrates, or species that feed on invertebrates and small fish prey.Apex predators typically had the highest mercury concentrations. In most species, mercury concentration increased as fish size increased. Sampling in Florida waters is continuing, and future research relating mercury levels to fish age, feeding ecology, and the trophic structure of Florida’s marine and estuarine ecosystems will help us better understand concentrations of this element in marine fishes.

Edmund Wilson\u27s America

When Edmund Wilson died in 1972 he was widely acclaimed as one of America\u27s great literary critics. But it was often forgotten by many of his admirers that he was also a brilliant and penetrating critic of American life. In a literary career spanning half a century, Wilson commented on nearly every aspect of the American experience, and he produced a body of work on the subject that rivals those of Tocqueville and Henry Adams. In this book, George H. Douglas has distilled the essence from Wilson\u27s many writings on America. An active reporter and journalist as much as a scholar, Wilson ranged from Harding to Nixon, from bathtub gin to marijuana. Douglas here surveys Wilson\u27s mordant observations on the roaring twenties, the Great Depression, income tax, suburbia, sex, populist politics, the Vietnam War, the Great Society, the failure of American scholarship, pollution of the landscape, and the breakdown of traditional American values. The Wilson who emerges from this survey is a historical writer with deep and unshakable roots in Jeffersonian democracy. Among his most far-seeing and poignant books are studies of the literature of the American Civil War and of the treatment of the American Indian. Pained by the crumbling moral order, Wilson was never completely at home in the twentieth century. In politics he was neither a liberal nor a conservative as those terms are understood today. He endured those ideologies and their adherents, but his genius was that he could bring them into hard focus from the perspective of the traditional American individualist who was too pained to accept the standardized commercial world that had grown up around him. Edmund Wilson\u27s America offers a distinctive overview of the nation\u27s life and culture as seen and judged by its leading man of letters. Professor of English at the University of Illinois, George H. Douglas has written on a variety of American authors and cultural matters, including a recent book on Chicago and the railroad.https://uknowledge.uky.edu/upk_english_language_and_literature_north_america/1052/thumbnail.jp
