Marine Ecotoxicology: Current Knowledge and Future Issues is the first unified resource to cover issues related to contamination, responses, and testing techniques of saltwater from a toxicological perspective. With its unprecedented focus on marine environments and logical chapter progression, this book is useful to graduate students, ecotoxicologists, risk assessors, and regulators involved or interested in marine waters.

As human interaction with these environments increases, understanding of the pollutants and toxins introduced into the oceans becomes ever more critical, and this book builds a foundation of knowledge to assist scientists in studying, monitoring, and making decisions that affect both marine environments and human health.

A team of world renowned experts provide detailed analyses of the most common contaminants in marine environments and explain the design and purpose of toxicity testing methods, while exploring the future of ecotoxicology studies in relation to the world's oceans. As the threat of increasing pollution in marine environments becomes an ever more tangible reality, Marine Ecotoxicology offers insights and guidance to mitigate that threat.

Provides practical tools and methods for assessing and monitoring the accumulation and effects of contaminants in marine environments Unites world renowned experts in marine ecotoxicology to deliver thorough and diverse perspectives Builds the foundation required for risk assessors and regulators to adequately assess and monitor the impact of pollution in marine environments Offers helpful insights and guidance to graduate students, ecotoxicologists, risk assessors, and regulators interested in mitigating threats to marine waters

Based on the work and contributions of 46 scientists, managers, and policymakers, Ecological Assessment of Selenium in the Aquatic Environment documents the state of the science and explores how to use this information when assessing and managing the environmental effects of Se. A focused discussion on the fate and effects of Se in aquatic ecosystems, the book reviews: Past and current problems related to Se in aquatic environments, together with lessons learned, and provides a generalized conceptual modelEnvironmental partitioning, in particular Se speciation leading to its entry into the food chain, and provides conceptual models specific to environmental partitioning.Se bioaccumulation and trophic transfer from the physical environment (i.e., water-column particulates), and from primary producers to herbivores to carnivores, including the influence of modifying ecological factorsToxic effects from Se, in particular body burdens and their relationship to toxicityFilled with practical guidance and concise information on how to conduct selenium risk assessments in the aquatic environment, the book contains the latest information on assessment techniques, elucidates the current state of contamination in industrialized countries, and raises awareness for developing nations. Written by leading experts, it describes best practices for designing experiments to collect information on aquatic effects and trophic transfer of selenium for risk assessments, presents numerous case studies both domestic and international, and gives insight as to how current and future ecosystems may or may not be affected.

Current procedures used for hazard identification and classification are based on persistence, bioaccumulation, and toxicity measurements. Assessing the Hazard of Metals and Inorganic Metal Substances in Aquatic and Terrestrial Systems provides the basis for improvements to the current model for hazard assessment. The book reviews the scientific underpinnings of the use of persistence as applied to metals, including bioavailability, and the use of bioaccumulation to evaluate aquatic species and aquatic-linked food chains. It also examines toxicity procedures as used within PBT approaches and measurements for metals in terrestrial ecosystems.The book brings together a multidisciplinary and international group of scientists, managers, and policy makers from Australia, Belgium, Canada, Germany, the Netherlands, the United Kingdom, and the United States to discuss various means for assessing the environmental hazard posed by metals and inorganic metal substances. The contributors include representatives from regulatory and nonregulatory government agencies, academia, industry, environmental groups, and consulting firms involved in assessment, management, and basic research of metals and metal substances. They provide a focused discussion of the fate and effects of metals in the environment, incorporating important advances developed over the past decade.
