Marine Pollution Emerging Issues And Challenges

As a society, we use more than 100,000 different industrial compounds to promote health and treat disease, to grow food and to access clean water. While technological developments have improved our lives, most of these compounds end up in our oceans where they threaten marine life and human health. The practice of ocean waste disposal has had a long history and was initially believed to have minimal associated costs. However, it is now clear that although we can use the oceans for cheap waste treatment, we do this at the expense of the other key benefits we derive from the sea, notably human food supplies as well as its aesthetic value (including opportunities for recreation and tourism). Many of the pollution problems of previous decades appear to have been solved in the developed world, or at least managed to minimise their environmental impacts. However, despite treatment being available for some waste products, a potent mixture of toxic compounds and other potentially harmful additions continue to enter the marine environment every day. So, have the problems of marine pollution really been solved or have we simply generated a suite of different and potentially more complex challenges? In this volume we consider marine pollution from the perspective of the historical problems that are now successfully managed or solved, the ongoing problems and the emerging challenges that we face. These include hormone mimics, the residues from pharmaceuticals, nanometre-sized particles added to new materials, the millimetric plastics added to shampoos and cosmetics, the artificial fibres in the clothes we wear, and the noise and light pollution from our expanding industries and cities. Marine Pollution is aimed at senior undergraduates, masters and graduate level students studying marine sciences. It will also serve as a useful reference for researchers and professionals working in the fields of environmental management, marine planning, marine environmental regulation and protection, as well as those working for government departments, environmental NGOs and marine environmental consultancies.

While oceans are vast, they represent a fragile resource that must be protected if we want to protect our livelihoods and our planet. Marine pollution has been a topic of concern for a long time, and it has recently attracted the attention of scientists, environmentalists, economists, politicians and journalists in mainstream media. Besides providing food, transportation routes and other resources, the oceans serve as a heat absorbing sink which offsets the extreme heating effects of climate change, but only to a limited degree. Pollution in marine environments such as the oceans, poses a threat to coastal communities by affecting the fauna and flora in the environment and the health of the nearby population. This has a disruptive effect on the health and economy of these communities. Marine Pollution: Current Status, Impacts and Remedies emphasizes the limitations of marine resources that relevant environments provide. Readers will find chapters on methods to assess pollution as well as important information for identifying, measuring, and remediating various pollutants. The book also covers some known pollutants (heavy metals, organic pollutants, microplastics) and ways to manage these substances. Other issues covered in the book include problems caused by invasive species, and the ecological problems caused by pollutants which affect local fauna and flora. This book will prove to be a useful resource for students, researchers, and policymakers, who are working in environmental science, marine conservation and allied fields. [Series Intro] Marine Ecology: Current and Future Developments brings forth contemporary issues in the study of marine environments. The scope of the series includes ecological, toxicological and biological aspects of the topic. Each volume of the series focuses on a broad theme, with reviews contributed by several experts in the field. The series is essential reading for environmental scientists, ecologists, conservationists and marine biologists.

Marine pollution occurs today in varied forms--chemical, industrial, and agricultural-and the sources of pollution are endless. In recent history, we've seen oil spills, untreated sewage, eutrophication, invasive species, heavy metals, acidification, radioactive substances, marine litter, and overfishing, among other significant problems. Though marine pollution has long been a topic of concern, it has very recently exploded in environmental, economic, and political debate circles; scientists and non-scientists alike continue to be shocked and dismayed at the sheer diversity of water pollutants and the many ways they can come to harm our environment and our bodies. In Marine Pollution: What Everyone Needs to Know, Judith Weis covers marine pollution from numerous angles, each fascinating in its own right. Beginning with its sources and history, she discusses common pollutants, why they are harmful, why they cause controversy, and how we can prevent them from destroying our aquatic ecosystems. Questions ask what actually happened with the Exxon Valdez, and why harmful algal blooms are a serious concern. Covering pollutants that are only now surfacing as major threats, such as pharmaceuticals, personal care products, and metal nanoparticles, she explains how these can begin in the water and progress up the food chain to emerge in human bodies. Looking at the effects of climate change and acidification on marine pollution levels, we learn how we can begin to reduce pollution at the local and global levels.

There is growing concern about the state of the world's oceans. The rapid growth of human populations in coastal regions has led to increasing dependence on marine resources. Beneficial features related to food supply and life style need to be balanced against the hazards presented by microbial pathogens, chemical pollutants, and toxic algal blooms. In this book, a group of experts from a range of backgrounds review the key aspects of the marine environment in relation to human health. An initial overview explains the need for integrating a range of disciplines, from physical oceanography and marine biology to molecular biology and epidemiology. Only by this approach can we hope to predict the consequences of environmental change and exploitation of natural resources upon our coastal ecosystems and, ultimately, on society and human health. Subsequent chapters then focus on more specialized topics. Firstly, waterborne pathogens are reviewed in detail and the microbial measures and policy implications important for protecting humans from exposure are described. Next, the consumption of contaminated seafood is considered along with its implications regarding the growth of aquaculture. Priority pollutants, emerging contaminants, and plastics are investigated as are the effects of climate change on pollution. Some phytoplankton produce biotoxins which accumulate in the flesh of filter-feeders such as bivalve molluscs. This creates a health risk when the shellfish are consumed by humans. The penultimate chapter, therefore, concentrates on harmful algal blooms (HABs) and the methodologies used to safeguard human health. The book concludes by proposing a holistic systems approach, such as Integrated Coastal Zone Management, to address the interconnected scientific challenges of increased human population pressure, pollution, over-exploitation of food resources, and the urgent need for effective public health solutions to be developed from politically and environmentally meaningful policies.

This book presents a broad overview of pollution issues facing climatic, economic, and legal globalization. Topics include changes in oceans from ancient times to the present, the importance of marine currents and changing climates, marine pollution linked to climate change (fossil fuels, global carbon dioxide, heavy metals, pesticides, plastics, emerging pollutants, and marine debris), global shipping and species invasion, global climate change in the Arctic and Antarctic environments, and regulatory responses to mitigate pollution and climate change in oceans.
