This book focuses on sediments as a pollutant in natural freshwater and marine habitats, and sediments as a vector for the transfer of chemicals such as nutrients and contaminants. The selected papers cover three main topics: assessment and/or restoration of disturbed watersheds; sediment-water linkages in terrestrial and aquatic environments; evaluation of sediment and ecological changes in marine and freshwater habitats.

Phosphorus is one of the major nutrients limiting the productivity of terrestrial, wetland and aquatic ecosystems. Over the last decade several research projects were conducted on Florida's ecosystems from state and federal agencies and private industry to address water quality issues, and to develop management practices to control nutrient loads. Phosphorus Biogeochemistry in Sub-Tropical Ecosystems is the first thorough study of the role of phosphorus in ecological health and water quality ever published. Because of its vast and extensively studied ecosystems, Florida has often served as a national laboratory on current and future trends in ecosystem management. The reader will find studies at all levels of biological organization, from the cellular to entire ecological communities. The book is a definitive study of the role and behavior of phosphorus deposition in the upland/wetland/aquatic environment. The papers presented in this book are organized in specific groups: ecological analysis and global issues, biogeochemical transformations, biogeochemical responses, transport processes, phosphorus management, and synthesis. Although Florida's ecosystems are used as a case study, the results presented have global applications.

Proceedings of a symposium held in Uppsala, Sweden, September 25-28, 1985

This Workshop was organized to assess the status of knowledge on the behaviour of phosphorus in sediments and to define gaps and reassess research strategies, particularly with respect to prevalent methodology and future approach; and to define gaps and reassess research strategies for water management measures in aquatic ecosystems, especially in relation to the release of phosphorus from the sediments and its impact on the functioning of the whole system.
