Download or read book Water Quality Impacts of Aquatic Dredged Material Disposal laboratory Investigations written by Sterling A. Burks and published by . This book was released on 1978 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural processes in aquatic ecosystmes tend to concentrate heavy metals, chlorinated hydrocarbons, pesticides, nutrients, and oil and grease compounds in bottom sediments. These contaminants are not very soluble in water under the conidtions that normally occur in oxygenated uncontaminated surface waters. Therefore, introducing high concentrations of these contaminants into aquatic ecosystems will generally result in an equilibrium condition where most of the contaminant will be sorbed (adsorbed and absorbed) by suspended particulate material and then deposited on the bottom when the suspended material settles. The time necessary to achieve the equilibrium condition depends upon the physicochemical conditions in the aquatic system and the quantity and duration of the contaminant introduction. Dredged Material Research Program (DMRP) reports and other literature indicate that dredging operations have the potential to temporarily mobilize or release some contaminants from the sediments. During disposal operations, the anaerobic sediments are mixed with aerated surface water, and a complex chemical interaction occurs. Heavy metals, such as cadmium, copper, chromium, lead, and zinc, are stabilized in the oxygen-free sediments as insoluble sulfides.

This book was released on 2001 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 592-page spiral-bound reference provides a baseline of information for all those involved with managing living marine resources in California and chronicles changes that have occurred in many of the state’s fisheries. Organized by marine ecosystems: bays and estuaries, nearshore and offshore. Includes illustrated species descriptions with details of biological knowledge, fishery history, landings data, population status and references. Also includes sections on marine birds and mammals and appendices containing management considerations (by species), a glossary of technical terms and acronyms and fishing gear illustrations. Jointly produced by the California Sea Grant Extension Program and the California Department of Fish and Game following the passage of the Marine Life Protection Act in January 1999.
