Download or read book Sand and Gravel Overlay for Control of Mercury in Sediments written by Leonard H. Bongers and published by . This book was released on 1972 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The release of toxic mercurials by mercury-enriched river sediments was examined in the laboratory. Tests showed a release of 1 micro g of methylmercury per sq m, per day. Methylmercury occurred in sediments with low and with high organic content, in sediments with low and high cation exchange capacity, and in aerobic and anaerobic sediments. The release of toxic mercury could be prevented by a layer of sand, 6 cm in thickness, applied over the mercury-enriched sediments. Layers of fine or coarse gravel (6 cm deep) were as effective as sand. A slow release of metallic mercury occurred in aerobic sediments. The release was much faster in anaerobic sediments. Using ascorbate as an artificial electron donor, metallic mercury could be released at high rates from aerobic sediments as well. Ascorbate appeared to be a useful indicator of divalent and biologically accessible mercury. The laboratory investigations proved the soundness of the sand blanket approach. Costs are given.

Download or read book Toxic Contamination in Large Lakes written by Schmidtke and published by CRC Press. This book was released on 1988-01-01 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every notable aspect of Toxic Contamination in Large Lakes is examined by known experts from every continent. Authors represent the U.S. and Canada, Argentina, Sweden, USSR, Israel, Great Britain, Japan, China, The Netherlands, Germany, Kenya, Austria. Authors represent the entire spectrum-academia, government, and industry. The first published work offer such a diverse and complete examination of this subject, it provides valuable information and data for today and tomorrow-and the basis for stimulating new research. Chapters in this work were reviewed and carefully edited, after initial presentation at the World Conference on Large Lakes held May 18-21, 1986 at Mackinac Island, Michigan. It presents a wealth of information...a resource for continued use over the years...and should do much to stimulate further study. This vital work is especially of interest to environmental scientists and toxicologists, fisheries professionals, researchers, aquatic resource managers, ecologists, biologists, chemists, and engineers. Every science or engineering library with a water interest should have this notable reference.

Download or read book Down by the Bay written by Matthew Booker and published by University of California Press. This book was released on 2020-06-09 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: San Francisco Bay is the largest and most productive estuary on the Pacific Coast of North America. It is also home to the oldest and densest urban settlements in the American West. Focusing on human inhabitation of the Bay since Ohlone times, Down by the Bay reveals the ongoing role of nature in shaping that history. From birds to oyster pirates, from gold miners to farmers, from salt ponds to ports, this is the first history of the San Francisco Bay and Delta as both a human and natural landscape. It offers invaluable context for current discussions over the best management and use of the Bay in the face of sea level rise.
