This book provides examples of pollutants, such as accidental oil spills and non-degradable plastic debris, which affect marine organisms of all taxa. Terrestrial runoff washes large amounts of dissolved organic materials from agriculture and industry, toxic heavy metals, pharmaceuticals, and persistent organic pollutants which end up into rivers, coastal habitats, and open waters. While this book is not intended to encyclopaedically list all kinds of pollution, it rather exemplifies the problems by concentrating on a number of serious and prominent recent developments. The chapters in this book also discuss measures to decrease and remove aquatic pollution to mitigate the stress on aquatic organisms. Aquatic ecosystems provide a wide range of ecological and economical services. In addition to providing a large share of the staple diet for a fast growing human population, oceans absorb most of the anthropogenically emitted carbon dioxide and mitigate climate change. As well as rising temperatures and ocean acidification, pollution poses increasing problems for aquatic ecosystems and organisms reducing its functioning and services which are exposed to a plethora of stress factors.

Aquatic ecosystems are currently experiencing unprecedented levels of impact from human activities including over-exploitation of resources, habitat destruction, pollution and the influence of climate change. The impacts of these activities on the microbial ecology of aquatic environments are only now beginning to be defined. One of the many implications of environmental degradation and climate change is the geographical expansion of disease- causing microbes such as those from the Vibrio genus. Elevating sea surface temperatures correlate with increasing Vibrio numbers and disease in marine animals (e.g. corals) and humans. Contamination of aquatic environments with heavy metals and other pollutants affects microbial ecology with downstream effects on biogeochemical cycles and nutrient turnover. Also of importance is the pollution of aquatic environments with antibiotics, resistance genes and the mobile genetic elements that house resistance genes from human and animal waste. Such contaminated environments act as a source of resistance genes long after an antibiotic has ceased being used in the community. Environments contaminated with mobile genetic elements that are adapted to human commensals and pathogens function to capture new resistance genes for potential reintroduction back into clinical environments. This research topic encompasses these diverse topics and describes the affect(s) of human activity on the microbial ecology and function in aquatic environments and, describes methods of restoration and for modelling disturbances.

This new volume addresses the environmental impacts of pollution on freshwater aquatic ecosystems and presents sustainable management and remediation practices and advanced technology help to address the different types of pollutants. Freshwater Pollution and Aquatic Ecosystems: Environmental Impact and Sustainable Management considers the need for sustainable, efficient, and cost-effective tools and technologies to assess, monitor, and properly manage the increasing issues of aquatic pollution. It provides detailed accounts of the phenomena and mechanisms related to aquatic pollution and highlights the problems and threats associated with pollution contamination in freshwater. It provides useful insight into the sustainable and advanced pollution remediation technology adopted by different countries for the monitoring, assessment, and sustainable management of pollution. The chapters in the volume evaluate the sources of harmful pollutants, which include industrial effluents, sewage, and runoff from agricultural industries, which result in toxic microbes, organic waste, oils, and high load of nutrients. Unsustainable management practices of domestic sewage and indiscriminate use of chemical pesticides lead to the technological disturbance of aquatic biota. In addition to harming aquatic biota, these pollutants find their way into the human body through inhalation, ingestion, or absorption and finally tend to bio-accumulate in trophic levels of the food chain, which poses a major risk to human beings. This book will be a valuable resource for ecologists, environmentalists, scientists, and many others for their work in understanding and management of aquatic pollutants in freshwater biospheres.

The global environment has been going through significant challenges in recent times due to a number of factors such as industrial pollution, expansion of agricultural land way beyond the fringe forest zones, destruction of virgin forests, loss of quality agricultural lands due to soil erosion, loss of global wildlife and biodiversity, climate change, global warming, devastating forest fires, floods, draughts, melting of glaciers to mention only a handful. The list could possibly go on and on with never ending items being added covering every aspect of modern human life. But there is an important underlying hidden factor behind all these that we all need to identify and realize. The most alarming fact about this hidden factor is that they are all directly or indirectly impacted by human activities in some way or other. Human civilizations have reached great strides from the earliest days when men first discovered wheel or learnt the art of agriculture and crop and livestock breeding. We have seen the age of computronics, robotics and now moving into the age of biotechnology, genetic engineering and nanotechnology. Our science quests have stretched beyond the borders of the home planet and we have even started stretching hands in unlocking the secrets of distant members of our solar system. This is indeed tremendous progress; there could be no doubt about that. But at the same time we also need to remember about the impending darkness too beneath the lamp that provides light to the rest of room. While we are standing in gaining a lot; but are we paying enough attention to what we are also loosing at the same time. The loss of forested areas, building up carbon dioxide in the global atmosphere, pollution of both fresh and salt water via number of toxic chemicals both of inorganic and organic nature, poor quality of the air we are breathing and the catastrophic loss of global biodiversity- are these not a sign of regress instead of the so called and highly cherished progress towards a darker and destructive future. Human or anthropogenic impacts are in turn devastating the planet with our attention being shifted only to the shinning aspect of our civilizations. There is indeed a darker side of every bright picture that is being placed in front of our glaring eyes. There is no silver lining in every cloud that we see on the sky. We are becoming seriously myopic and choosing to ignore the deadly symptoms that are showing up in front of us every now and then as a result of our own activities. Anthropogenic impacts have been devastating to our global ecosystems and are challenging our local environments in a significant manner. As responsible global citizens we strongly believe that we need to voice our concerns to the incessant global environmental pollution happening at every instance at different corners of earth. Hence is the humble effort of coming up with an international, peer-reviewed volume on Anthropogenic Pollution: Causes and Concerns. The current volume is a collection of a number of articles from scientists, academics, researchers, journalists, bureaucrats and technocrats from different parts of the world. Each article talks about a separate story and highlights some specific problems caused by anthropogenic impact and resulting in detrimental forms of environmental pollution. Each article is complete with its table, graphs, diagrams and bibliography to cater to a wide range of readers from serious academics, researchers and students to environmental enthusiasts and general public interested in stretching their boundary of knowledge way beyond traditional education. The volume will also be useful for both under graduate and post graduate students specializing in environmental science/studies and also for the MPhil curriculum and entry level PhD courses at different academic institutes.

The indiscriminate use of chemical substances in industrial processes and anthropogenic activities, have resulted in the release of these compounds into aquatic ecosystems through municipal, hospital and industrial discharges, producing various undesired effects on the environment and on species of ecological interest. These compounds, such as metals, pesticides, emerging pollutants and other substances are persistent and susceptible to biotic and/or abiotic transformations, yielding metabolites that can be more toxic than the original compounds. In this book, researchers from diverse environmental science disciplines share their experiences in countries such as Argentina, Brazil, Colombia and Mexico, and critically examine the problem of contaminants in aquatic ecosystems in Latin America, as well as the risks presented by their presence.
