Sediment Quality Assessment and Management in Marine and Freshwater Environments: Current Approaches, Emerging Tools, and Future Directionsaddresses the urgent need for practical, state-of-the-science guidance on assessing and managing contaminated sediments in both marine and freshwater systems. Recognizing the vital role sediments play in water quality, ecosystem health, and human infrastructure, this comprehensive volume bridges the gap between scientific principles and real-world management practices. The book provides a thorough examination of current assessment frameworks, diagnostic tools, and innovative methodologies, while highlighting the unique challenges of transboundary and site-specific sediment management. With contributions from leading experts, it offers clear insights into the biological, chemical, and geophysical factors that influence sediment quality, and explores the latest advances in ecotoxicology, bioavailability, passive sampling, risk assessment, and remediation. Designed for students and researchers of sediment quality, marine biologists, and professionals studying water quality and hydrology, this essential reference equips readers with the knowledge and strategies needed to protect aquatic resources and human uses of the aquatic environment, setting a new standard for sediment quality management worldwide. Offers a comprehensive review and summary of sediment quality assessment and toxicity testing methods-including environmental chemistry, investigation techniques, data assessment approaches, exposure potential, and ecological toxicity Includes the latest techniques for managing sediments, with case studies on legacy contamination, integration of effect-based methods, sustainable use of dredged material, and the role of sediment quality in supporting marine protected areas and ecosystem services Provides in-depth discussion of new and emerging tools for sediment quality assessment, including passive sampling, advanced ecotoxicological methods, novel diagnostic tools, and eDNA-based monitoring of benthic communities
