Book Description
Sediments contaminated by human activities usually contain a mixture of chemicals that produce unforeseen combined toxic effects in organisms. Thus, traditional risk assessments based on the concentrations of chemicals are unlikely to produce realistic data on toxicity. In the CONTEST project, 19 biotests were evaluated using a model contaminated sediment from the Baltic Sea. Most of the biotests applied showed concentration-dependent toxicity related to the degree of chemical pollution measured in the test sediment with some variability in the sensitivity of the test organism and the endpoint. The different biotests were analysed according to specially designed assessment criteria, and the results are foreseen to be useful for end-user groups including environmental authorities, private companies and industries, environmental laboratories, consultants, and the scientific community.

Book Description
This book presents in detail the state of knowledge of the distribution, bioavailability, biomagnification, discrimination, fate and sources of chemical pollutants (metals, metalloids, radionuclides and nutrients) in all compartments (atmosphere, water, deposits, biota) of the Baltic environment. Particular components of the Baltic ecosystem are considered as potential monitors of pollutants. Budgets of chemical elements and the ecological status of the Baltic Sea in the past, present and future are presented. Estimates of health risks to man in respect to some toxic metals and radionuclides in fish and seafood are briefly discussed. The content of the book makes possible the identification of gaps in our environmental knowledge of the Baltic Sea, with certain sections establishing possible priorities, key areas or strategies for future research.

Book Description
This book describes how man-made litter, primarily plastic, has spread into the remotest parts of the oceans and covers all aspects of this pollution problem from the impacts on wildlife and human health to socio-economic and political issues. Marine litter is a prime threat to marine wildlife, habitats and food webs worldwide. The book illustrates how advanced technologies from deep-sea research, microbiology and mathematic modelling as well as classic beach litter counts by volunteers contributed to the broad awareness of marine litter as a problem of global significance. The authors summarise more than five decades of marine litter research, which receives growing attention after the recent discovery of great oceanic garbage patches and the ubiquity of microscopic plastic particles in marine organisms and habitats. In 16 chapters, authors from all over the world have created a universal view on the diverse field of marine litter pollution, the biological impacts, dedicated research activities, and the various national and international legislative efforts to combat this environmental problem. They recommend future research directions necessary for a comprehensive understanding of this environmental issue and the development of efficient management strategies. This book addresses scientists, and it provides a solid knowledge base for policy makers, NGOs, and the broader public.

Book Description
From fisheries to persistent organic pollutants to climate change itself, no other environmental principle in environmental law has produced as much controversy as the precautionary principle. Unlike a preventive approach in which action is taken provided that the threats to the environment are tangible, with a precautionary approach, authorities are prepared to tackle risks for which there is no definitive proof that the damage will materialize. The ramifications of this increasingly apparent approach are profound and cut across all areas of risk assessment and management, environmental law, policy and regulation in every major sector. However, to date little thought has been dedicated to the implementation of the precautionary principle in a wide array of environmental circumstances. This authoritative handbook addresses the legal aspects of how the precautionary principle is implemented in different sectors, and examines its successes, failures, strengths and weaknesses. Sectors and subjects covered include chemicals, GMOs, marine pollution, fisheries and nature conservation, and the book draws on cases in the EU, in the USA, and Nordic countries, where the use of precaution has been gathering momentum. Ultimately, the book provides an indispensable appraisal of the question - increasingly important in the era of human-induced climate change - of whether the precautionary principle is relevant, indeed essential, to avert major environmental and health risks, and how and when it can be used successfully.

Book Description
During recent decades, large-scale effects of pollution on marine estuaries and even entire enclosed coastal seas have become apparent. One of the first regions where this was observed is the Baltic Sea, whereby the appearance of anoxic deep basins, extensive algal blooms and elimination of top predators like eagles and seals indicated effects of both increased nutrient inputs and toxic substances. This book describes the physical, biochemical and ecological processes that govern inputs, distribution and ecological effects of nutrients and toxic substances in the Baltic Sea. Extensive reviews are supplemented by budgets and dynamic simulation models. This book is highly interdisciplinary and uses a systems approach for analyzing and describing a marine ecosystem. It gives an overview of the Baltic Sea, but is useful for any marine scientist studying large marine ecosystems.

Book Description
The processes occurring in surface marine sediments have a profound effect on the local and global cycling of many elements. This graduate text presents the fundamentals of marine sediment geochemistry by examining the complex chemical, biological, and physical processes that contribute to the conversion of these sediments to rock, a process known as early diagenesis. Research over the past three decades has uncovered the fact that the oxidation of organic matter deposited in sediment acts as a causative agent for many early diagenetic changes. Summarizing and discussing these findings and providing a much-needed update to Robert Berner's Early Diagenesis: A Theoretical Approach, David J. Burdige describes the ways to quantify geochemical processes in marine sediment. By doing so, he offers a deeper understanding of the cycling of elements such as carbon, nitrogen, and phosphorus, along with important metals such as iron and manganese. No other book presents such an in-depth look at marine sediment geochemistry. Including the most up-to-date research, a complete survey of the subject, explanatory text, and the most recent mathematical formulations that have contributed to our greater understanding of early diagenesis, Geochemistry of Marine Sediments will interest graduate students of geology, geochemistry, and oceanography, as well as the broader community of earth scientists. It is poised to become the standard text on the subject for years to come.

Book Description
Pharmaceuticals in Marine and Coastal Environments: Occurrence, Effects, and Challenges in a Changing World is divided into three sections that address a) coastal areas as the main entrance of pharmaceuticals into the ocean, b) the occurrence and distribution of pharmaceuticals in the environmental compartments of the ocean media, and c) the effects that such pollutants may cause to the exposed marine organisms. With its comprehensive discussions, the book provides a wide depiction of the current state-of-the-art on these topics in an effort to open new sources of investigation and find suitable solutions. - Includes maps edited by the Water Information Network System of the International Hydrological Program (IHP-WINS) - Provides a compilation of information regarding the occurrence and distribution of pharmaceuticals in the marine environment which will help establish new and more efficient monitoring programs and new research lines - Depicts the most important results of environmental risk assessments that can be used as a first step for further toxicological studies
