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.

Environmental Chemistry is a relatively young science. Interest in this subject, however, is growing very rapidly and, although no agreement has been reached as yet about the exact content and limits of this interdisciplinary subject, there appears to be increasing interest in seeing environmental topics which are based on chemistry embodied in this subject. One of the first objectives of Environ mental Chemistry must be the study of the environment and of natural chemical processes which occur in the environment. A major purpose of this series on Environmental Chemistry, therefore, is to present a reasonably uniform view of various aspects of the chemistry of the environment and chemical reactions occuring in the environment. The industrial activities of man have given a new dimension to Environ mental Chemistry. We have now synthesized and described over five million chemical compounds and chemical industry produces about one hundred and fifty million tons of synthetic chemicals annually. We ship billions of tons of oil per year and through mining operations and other geophysical modifications, large quantities of inorganic and organic materials are released from their natural deposits. Cities and metropolitan areas of up to 15 million inhabitants produce large quantities ofwaste in relatively small and confined areas. Much of the chemical products and was te products of modern society are released into the environment either during production, storage, transport, use or ultimate disposal. These released materials participate in natural cycles and reactions and frequently lead to interference and disturbance of natural systems.

This book addresses a complex issue – water sustainability – that requires a combined approach to manage both water and energy. It highlights several technologies that have been introduced to study the water–energy linkage. It also discusses the need to develop effective laws for water management. In turn, the book assesses hybrid biological systems and demonstrates why they are better for the wastewater treatment process. Lastly, it reviews wastewater quality requirements, which have been the primary driver of industrial wastewater treatment programs in India. Gathering selected, high-quality research papers presented at the IconSWM 2018 conference, the book offers a valuable asset, not only for researchers and academics, but also for industrial practitioners and policymakers.

Synthetic detergents rapidly replaced soap for most domestic cleaning purposes after World War II. Concurrently, great billows of foam began passing undegraded through sewage treatment plants into receiving waters, which were often sources for domestic water supplies. The detergent industry quickly learned that many surface-active agents--the active ingredients of synthetic detergents and the producers of foam--were not readily biodegradable. The most popular surface-active agent was alkyl benzene sulfonate (ABS). Industrialized societies had developed satisfactory sewage processes to treat domestic wastes, but even the most advanced treatment facilities proved incapable of degrading ABS. Biodegradable examines the development of synthetic detergents and the unanticipated pollution of surface waters and groundwaters by this new technology, as well as the social, political, and industrial responses that resulted in correction of the problem. Public and governmental pressure in the United States, the United Kingdom, and the Federal Republic of Germany led to the international detergent industry's finding a biodegradable substitute for ABS, namely, linear alkyl sulfonate (LAS). Its use from the mid-1960s solved the foaming pollution problem. The three countries responded to the problem very differently. West Germany almost immediately legislated that only those detergents that were more than eighty percent biodegradable could be sold. The U.S. government allowed the detergent industry to seek a solution while the Department of Health, Education, and Welfare monitored the industry's progress. In the U.K. the government created committees and required industry to cooperate with them to find a solution. Biodegradable not only examines problems resulting from a new technology but also compares and contrasts different societies' methods of dealing with these problems.

This book contains plenary papers and selected poster presentations from the AOCS-sponsored World Conference held in Montreux, Switzerland.

In to days market, custom formulated surfactants are offered for a wide range of applications. The need for surfactants in detergents, cleaning agents, cosmetics & toiletries is second only to an expanding demand in industrial applications. But even within the non-industrial areas the demands have undergone significant changes in recent years. For example, washing and cleaning temperatures have substantially decreased with increased energy conservation attitudes, and more stringent regulatory requirements in the area of ecology and toxicology are leading to new product profiles. New manufacturing technologies and an increased utilization of natural raw materials also factor into this continuing evolution. These changes and trends have been described in numerous publications. However, a summary and survey of these developments is currently missing. The book presented here "Surfactants in Consumer Products" is intended to close this gap. The editor and authors dedicate this work to Dr. Dr. h.c. Konrad Henkel on the occasion of his 70th birthday. Dr. Henkel, himself a scientist and industrialist, contributed signifi cantly to developments in the surfactant field. In the nineteen-fifties, he initiated the change from soap based detergents to synthetic detergents within Henkel. At the same time, dishwashing detergents utilizing various synthetic surfactants were also developed, and became the basis for modem manual and mechanical dishwashing.

Reviews national water pollution control policy, and considers legislation to establish a Federal Water Pollution Control Administration, and to establish water pollution control standards and Federal pollution control loan programs.
