Download or read book Nonylphenol and Its Ethoxylates Draft written by and published by . This book was released on 2000 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonylphenol ethoxylates are a class of high-volume chemicals used as detergents, emulsifiers, wetting agents, and dispersing agents. These chemicals and their degradation products such as nonylphenol are not produced naturally, and enter the environment primarily through wastewater treatment plant effluents. This report summarizes the information critical to the assessment of these chemicals as toxic, including their identity, properties, production, and uses; entry into the environment; fate and concentrations; toxicokinetics; and effects on experimental animals and in vitro and on humans; and ecotoxicology. The report also includes an assessment under the Canadian Environmental Protection Act of these chemicals regarding their toxicity in the environment and their population exposure & human health effects.

National Guidelines and Standards Office and published by National Guidelines and Standards Office. This book was released on 2002 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonylphenyl (NP) and NP ethoxylates (NPEs) are a group of organic chemicals that are widely used as surfactants, emulsifiers, wetting agents, and dispersants in a wide variety of industrial processes & commercial products. This document provides the rationale for development of Canadian environmental quality guidelines for NP & NPEs. It contains technical background information on the chemical & physical properties of NP & NPEs and a review of their sources & emissions in Canada, the distribution & behaviour of these chemicals in the environment, their toxicological effects on aquatic & terrestrial species, and NP/NPE guidelines developed in other jurisdictions. The information is then used to derive water, sediment, & soil quality guidelines for NP/NPEs to protect ecological receptors in each of these environmental compartments. The final sections suggest areas for future research & provide guidance on implementation of the guidelines.

Download or read book Analysis and Fate of Surfactants in the Aquatic Environment written by Thomas P. Knepper and published by Elsevier. This book was released on 2003-08-22 with total page 995 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

It provides the necessary applications for modifying the paradigm and shows how to use it to perform an effective assessment. Topics include: fate and bioavailability of organic compounds, emerging contaminants, effects of populations, effects to marine mammals, risk from multiple stressors, European approaches to risk assessment, effects of land use, and more.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
