Book Description
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.

Book Description
This report gives a perspective of national and international legislation and obligations; addresses the quality of Pacific, Arctic and Atlantic coasts and marine waters; presents an overview of Canada's marine environmental quality (MEQ) and identifies some next steps. The report focuses on threats to MEQ from toxic chemicals, industrial emissions, and anthropogenic physical changes.

Book Description
Marine management requires approaches which bring together the best research from the natural and social sciences. It requires stakeholders to be well-informed by science and to work across administrative and geographical boundaries, a feature especially important in the inter-connected marine environment. Marine management must ensure that the natural structure and functioning of ecosystems is maintained to provide ecosystem services. Once those marine ecosystem services have been created, they deliver societal goods as long as society inputs its skills, time, money and energy to gather those benefits. However, if societal goods and benefits are to be limitless, society requires appropriate administrative, legal and management mechanisms to ensure that the use of such benefits do not impact on environmental quality, but instead support its sustainable use.

Book Description
This book provides an updated revision and examples of application of indicators available to assess the status of coastal and transitional ecosystems. Moreover, a decision tree to be used as guidance in selecting which indicators should be applied in any particular case involving benthic fauna is proposed. Finally, differences in performance of various indicators are illustrated through a series of case studies on marine and estuarine ecosystems.

Book Description
Is ecological knowledge relevant to environmental policy and if so, to what extent and in what way? After a series of oxygen depletion events in coastal waters in the 1980s, North Sea states acted to reduce inputs of nitrogen and phosphorus to the North Sea. The book analyzes the role of scientists and scientific information, as well as civil servants, in the formulation and implementation of these decisions.

Book Description
Understanding marine pollution and the contamination of coastal environments requires knowledge from a variety of scientific fields. Marine Environmental Quality promotes a multidisciplinary approach to investigations, drawing on not only natural sciences, but also applied mathematics and social sciences. The investigations in this book focus on both organic and inorganic pollutants, firstly in a study conducted in the city of La Rochelle, on the North Atlantic French coast, then expanding the areas under examination to regions of English and Portuguese waters and, lastly, to the Mediterranean Sea. The improvement such research can bring to biomarkers, models and experiments enables equal progress in the quality of seawater in ports and protected areas of coastal regions. The eight chapters of Marine Environmental Quality present many aspects of this research, including experiments with floating barriers, water governance in various areas, sampling sites and sentinel species that act as biomarkers in harbors. Also covered are environmental commitments, both international and local, the risk that marine contamination poses to human health, experimental designs for interactions with microplastics and a study biomonitoring the juveniles of sentinel species. Such results will bring many benefits, to human health, to economic inclusion and to regional development.

Book Description
Coastal and marine ecosystems, some severely degraded, other still pristine, control rich resources of inshore environments and coastal seas of Latin America's Pacific and Atlantic margins. Conflicts between the needs of the region's nations and diminishing revenues and environmental quality have induced awareness of coastal ecological problems and motivated financial support for restoration and management. The volume provides a competent review on the structure, processes and function of 22 important Latin American coastal marine ecosystems. Each contribution describes the environmental settings, biotic components and structure of the system, considers trophic processes and energy flow, evaluates the modifying influence of natural and human perturbations, and suggests management needs. Although the focus of the book is on basic ecological research, the results have application for coastal managers.
