The goal of this one-of-a-kind book was to provide a critical and in-depth understanding of various AVS-SEM models as predictors for assessing the ecological impact of heavy metals (particularly dibasic cations; Zn, Cd, Ni, Cu, and Pb) on aquatic environments, including the theories underlying these models, descriptive equations, modes of action, methodology, efficiency, applicability, and statistical approaches, as well as comparison with other pollution assessment techniques in the aquatic environments. Metals in interstitial water can be reduced in sediments that co-precipitate with iron (Fe) and manganese (Mn) in FeS or MnS minerals, as well as replace them. This book outlines a system that can be used to track heavy metal contamination in countries with coastal regions that extend over water bodies that are subjected to pollution sources, such as the Mediterranean Basin countries. Moreover, this book will be of great interest to academics, professionals, practitioners, post-graduate students (M.Sc. and Ph.D.), and undergraduates because it gives a clear overview of heavy metal assessment for people interested in environmental studies focusing on the marine environment. It also provides decision-makers with a realistic perspective of the environmental file, allowing them to address environmental issues and directing stockholders to safer locations for environmental activity. From a future perspective, management is advised to overcome the difficulties within that technique, such as accurate handling procedures and different approaches to sampling onshore and offshore. Sequential leaching strategies, especially geochemical fractionation analysis, and knowledge of the interactions and significance of AVS in the marine sector, especially toxicity tests (bioassay) are recommended.

Skickas inom 10-15 vardagar
This book addressed an in-depth comprehension of the classifications and characterizations of POPs, which have become global issues due to bioaccumulation, persistency, and toxicity. The book emphasizes models for predicting the annual contribution rate of POPs as a way to raise public awareness about POPs.

Organometallic Compounds in the Marine Environment
Analytical and Ecological Aspects

Skickas inom 10-15 vardagar
This book outlines organometallic compounds (OMCs) in the marine environment, focusing on their analytical and ecological aspects. Divided into 6 chapters, the authors discuss OMCs' occurrence, chemical structure, and environmental impact of OMCs in aquatic systems. In this book, readers will also find critical insights into the sources and effects of OMCs on marine ecosystems, with detailed discussions on extraction methodologies, stability, and speciation analysis. The book highlights advanced analytical techniques such as gas chromatography and atomic absorption spectrometry, providing a thorough understanding of the latest approaches for evaluating OMC levels in marine environments.Particular attention is given to the fate and behaviour of OMCs in various environmental compartments, their ecotoxicology, and molecular modelling studies describing toxicity mechanisms. The book also addresses global distribution patterns with a focus on hotspots and evaluates joint efforts for prevention and sustainability.This volume is indispensable for researchers in marine chemistry, postgraduate students, industry scientists working on environmental pollutants, ecologists studying marine ecosystems, and policymakers involved in environmental protection. It invites readers to think critically about sustainable development goals related to clean water (SDG 6) and life below water (SDG 14), emphasizing the need for continued research to mitigate the impact of hazardous materials like OMCs, and for policy development.
Rethinking Seaweeds via Applications and Technologies
Composition, Toxicology, Economy and Sustainability

This book explores the basic structure, distribution, ecological, and commercial applications (pharmaceutical, medical, cosmetic, nutritional; food and feed source, agriculture, industrial, biodiesel, and nanotechnology), risks, and sustainability of seaweeds. Also, this book presents in detail the primary and secondary metabolites and their significance in traditional and pharmaceutical medicine, as well as cosmetics. Using various computational and informatics frameworks, targeted seaweed omics research can quickly advance our understanding of molecular biological processes and help address today’s most pressing environmental and social issues. Furthermore, this book explains how seaweed can operate as a “carbon capture and storage” system in nature. It suggests a framework for the term “forensic carbon accounting," which will be important in building a technique for ocean afforestation. Moreover, this book highlighted seaweed resilience research as important for better understanding species-specific sensitivity to marine heatwaves and identifying which coastal sites are most vulnerable to regime changes. Added to the above, this book deeply discusses different technologies that are used to isolate bioactive compounds from seaweed. Additionally, this book discusses the technical and social framework based on ecosystem awareness that supports the objective of sustainable seaweed benefit use. Authors assess policy development, awareness, challenges, and advertising benefits in order to draw attention to the significance of the topic of our book. The information and knowledge presented in the book on the advantages and uses of products based on seaweed would be of particular interest to researchers in the marine field, postgraduate students, and audiences from different disciplines who are interested in marine topics and seaweeds in particular. Socioeconomic research on seaweed uses are beneficial to society and decision-makers alike. Finally, this book motivates the audience to rethink seaweeds as vital components that support many ecosystems in their natural state and offer several ecological and economic services to humans.
