The book summarizes and reviews the environmental and human safety of two classes of nonionic surfactants-alcohol ethoxylates (AE) and alkylphenol ethoxylates (APE). This unique resource contains critical data from published sources as well as from unpublished studies submitted by Soap and Detergent Association member companies. It reviews information on product chemistry and analysis, biodegradation, environmental levels (including fate and distribution), aquatic toxicity, and human safety. Recently developed analytical techniques for the extraction, separation, detection, and measurement of nonionic surfactants and their metabolites in environmental samples are described. Results of biodegradation studies performed with a variety of test systems are tabulated, as are results of field studies at wastewater treatment plants. Reported comparisons of environmental levels with results of acute and chronic aquatic toxicity tests are provided. The information on the toxicity and irritation potential of AE and APE surfactants includes data from in vitro, mammalian, and human studies.

The focus of Handbook for Cleaning/Decontamination of Surfaces lies on cleaning and decontamination of surfaces and solid matter, hard as well as soft. Bringing together in a 2-volume reference source: - current knowledge of the physico-chemical fundamentals underlying the cleaning process; - the different needs for cleaning and how these needs are met by various types of cleaning processes and cleaning agents, including novel approaches; - how to test that cleaning has taken place and to what extent; - the effects of cleaning on the environment; - future trends in cleaning and decontamination, for example the idea of changing surfaces, to hinder the absorbance of dirt and thus make cleaning easier.A brief introduction is given to the legal demands concerning the environment and a historical background, in terms of development of detergents, from soaps to the modern sophisticated formulations. Bactericides, their use and the environmental demands on them are covered. Thorough discussions of mechanisms for cleaning are given in several chapters, both general basic concepts and special cases like particle cleaning and cleaning using microemulsion concepts.* General understanding of how cleaning works, function of ingredients and formulations * Overview of environmental issues and demands from the society in the area * Gives basic formulas for cleaning preparations in most areas

An understanding of the fate and behaviour of organic chemicals, such as surfactants, in the environment is a prerequisite for the sustainable development of human health and ecosystems. As surfactants are being produced in huge amounts, it is important to have a detailed knowledge about their lifetime in the environment, their biodegradability in wastewater treatment plants and in natural waters, and their ecotoxicity. Parameters relevant for the assessment of long-term behaviour, such as interactions with hormonal systems need to be understood to avoid unexpected adverse effects to future generations of people and the environment. However, the identification and quantification of commercial surfactants in the environment is made more complicated and cumbersome because they comprise of tens to hundreds of homologues, oligomers and isomers of anionic, nonionic, cationic and amphoteric compounds.The EU-funded PRISTINE project (Priority surfactants and their toxic metabolites in wastewater effluents: An integrated study; ENV4-CT97-0494) provides the basis for the content of this title. It provides policy makers and industry with detailed information on analysis and concentrations of surfactants and their degradation products in the environment.In addition to a general introduction to surfactants, this book comprises a comprehensive variety of analytical techniques, including sample handling, for the analysis of surfactants in the aquatic environment. Readers will find all the necessary information for analyzing the different groups of surfactants, with special emphasis on transformation products. Quality assurance is also reported on in detail. Chapters on toxicity and risk assessment are also included and give a complete perspective on the surfactants problem in the aquatic environment.·Presents the finding of EU-funded research into fate and behaviour of organic chemicals in the environment·Comprises a comprehensive variety of analytical techniques, including sample handling, for the analysis of surfactants in the aquatic environment·Provides relevant information to all groups working in the field of surfactants

Environmental considerations are increasingly shaping the development of many industries. This is an overview of surfactants and the environment. It goes on to look at new surfactants derived from renewable, "natural" resources such as sucrose, seaweed and starch. Other chapters review a decade of change in the surfactant industry and assess future market trends. Some of the developments in surfactant technology are presented, including "gemini" twin-chained surfactants, sulfobetaines, alkyl phosphates and the use of alkyl alkoxylates and alkyl glucosides in highly alkaline solutions. The volume takes a practical approach throughout.

Pollution: Causes, Effects and Control is the fourth edition of a best-selling introductory level book dealing with chemical and radioactive pollution in its broadest sense. The scope of the book ranges from the sources of pollutants and their environmental behaviour, to their effects on human and non-human receptors, to the technologies and strategies available for control. The fourth edition has been wholly revised and updated from the previous edition due to the rapid pace of developments in this field. Topics covered include chemical pollution of freshwater and marine environments, drinking water quality, water pollution biology, sewage and its treatment, toxic wastes, air pollution and atmospheric chemistry, control of pollutant emissions, land contamination, solid waste management, clean technologies, persistent organic pollutants in the environment, environmental radioactivity, health effects of environmental chemicals, legal control of pollution and integrated pollution control. There is a completely new chapter on Clean Technologies and Industrial Ecology, reflecting the growing importance of pollution prevention as opposed to end-of-pipe solutions. Whilst originally intended as an introductory reference work for professionals within the field, the book has been widely adopted for teaching purposes at the undergraduate and postgraduate level.

Sustainability is a key driving force for industries in the chemical, food, packaging, agricultural and pharmaceutical sectors, and quantitative sustainability indicators are being incorporated into company reports. This is driving the uptake of renewable resources and the adoption of renewables. Renewables' can either be the substituted raw materials that are used in a given industry, (e.g. the use of biomass for fuel); the use and/or modification of a crop for use in a new industry (e.g. plant cellulose), or the reuse of a waste product (e.g. organic waste for energy production). This is the first book in the Wiley Renewable Resources series that brings together the range of sustainability assessment methods and their uses. Ensuing books in the series will look at individual renewable materials and applications.
