Includes bibliographical references. "Contaminated sediment has been identified as a source of ecological impacts in marine, and freshwater systems throughout the world and the importance of the contaminated sediment management issue continues to rise in all industrialized countries. In many areas, dredging or removal of sediments contaminated with nutrients, metals, oxygen demanding substances and persistent, toxic, organic chemicals has been employed as a form of environmental remediation. In most situations, however, the documentation of the sediment problem has not been quantitatively coupled to ecological impairments. As a result, stipulating how much sediment needs to be cleaned up, why, and what improvements can be expected over time has been inadequate. In addition, the lack of long-term, post activity research and monitoring for most projects has impeded a better understanding of the ecological significance of sediment contamination. This paper reviews many of the known links and impacts, and examines the results from some case studies"--Abstract. gccst Sediments gccst Aquatic ecosystems gccst Water pollution Hartig, John Henry, 1952- author.
