Heavy Metals in the Marine Environment
Author: Robert W. Furness
Publisher: CRC Press
ISBN: 1351081608
Category : Science
Languages : en
Pages : 262
Book Description
The aim of this volume is to draw together state-of-the-art reviews of knowledge onlevels of heavy metals in marine environments (particularly in marine animals), the dynamicprocesses in these systems, toxic effects, and threats presented by heavy metals in foods ofmarine origin.All heavy metals, whether biologically essential or not, have the potential to be toxicto organisms at a threshold bioavailability. Such threshold concentrations vary betweenmetals, between species and with the physicochemical characteristics of the medium, somelike copper being particularly toxic even though essential in trace amounts. Responses ofanimals to metals in their medium or food depend to a large extent on the ability of speciesto regulate levels attained in their tissues. Higher animals have the capacity to regulate levelsof many metals, while marine invertebrates can regulate some within certain limits. Whereanimals cannot regulate physiological levels of metals, an alternative strategy is to detoxifyand store metals in relatively harmless forms. Knowledge of the manner in which animals deal with potentially toxic concentrations of heavy metals is of fundamental importance in the assessment of metal pollution by analysis of metal levels in biological samples. The interaction of heavy metals with biological materials is a key theme running through this volume. Toxic effects may be reflected at the individual, population, or ecosystem level, affecting species composition and production levels, or may be of direct dietary significance to man. The global cycling of metals through the marine environment is crucially affected by biological processes.

Heavy Metals in the Aquatic Environment
Author: P. A. Krenkel
Publisher: Elsevier
ISBN: 1483144437
Category : Science
Languages : en
Pages : 363
Book Description
Heavy Metals in the Aquatic Environment contains the proceedings of an international conference held in Nashville, Tennessee in December 1973. This conference is co-sponsored by the International Association on Water Pollution Research, the Sport Fishing Institute, the American Fishing Tackle Manufacturers Association, and Vanderbilt University's Department of Environmental and Water Resources Engineering. Contributors focus on the hazards posed by heavy metals present in the aquatic environment and how to control them. This text consists of 45 chapters divided into eight sections. This book assesses the environmental impact of heavy metals found in the aquatic environment; the economic impact of removing them from waste effluents; and the costs vs. benefits attained by their removal. The social costs are also evaluated. After an introduction to dose-response relationships resulting from human exposure to methylmercury compounds, the discussion turns to the toxicity of cadmium in relation to itai-itai disease; the effects of heavy metals on fish and aquatic organisms; and the analytical methods used for measuring concentrations of methylmercury and other heavy metals. The next sections explore the transport, distribution, and removal of heavy metals, along with regulations, standards, surveillance, and monitoring aimed at addressing the problem. This book will be of interest to planners and policymakers involved in water pollution control.

Lead, Mercury and Cadmium in the Aquatic Environment
Author: Rachel Ann Hauser-Davis
Publisher: CRC Press
ISBN: 100088709X
Category : Science
Languages : en
Pages : 251
Book Description
This book presents an integrated and holistic discussion on cadmium, lead and mercury toxicity in aquatic environments, expanding general concepts on chemical speciation effects and exploring specific environmental toxicological issues, exposure routes, and bioanalytical approaches for their determination and assessments on their intracellular deleterious effects. It contains worldwide and regional aspects on cadmium, lead and mercury occurrence, fate, and toxicity, addressing key environmental exposure and health risk concerns to both humans and aquatic organisms. Our book is of interest to anyone conducting research in the broad fields of oceanography, geochemistry, ecotoxicology, and environmental and public health.
