Book Synopsis Biodegradability of Surfactants by : D.R. Karsa
Download or read book Biodegradability of Surfactants written by D.R. Karsa and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: The awareness and development of 'biodegradable' surfactants pre-dates current pressures by the environmental movement by nearly three decades, wherein a responsible industry mutually agreed to replace 'hard', non-biodegradable com ponents of household detergents by 'soft', biodegradable alternatives, without course to legislation. The only requirement at that time was for surfactants used in detergents to exhibit a 'primary biodegradability' in excess of 80%; this referring to the disap pearance or removal from solution of the intact surface active material as de tected by specified analytical techniques. This proved useful, as observed environmental impacts of surfactants, e.g. visible foam on rivers, are associated with the intact molecule. Test methods for 'primary biodegradability' were eventually enshrined in EU legislation for nonionic surfactants (Directive 821242/EEC, amended 73/404IEEC) and for anionic surfactants (Directive 8212431EEC, amended 73/405IEEC). No approved test methods and resultant legislation have been developed for cationic and amphoteric surfactants to date. The environmental classification of chemical substances, which of course includes surfactants, and associated risk assessment utilises a second criterion 'ready biodegradability'. This may be assessed by a number of methods which monitor oxygen uptake (BOD), carbon dioxide production or removal of dis solved organic carbon (DOC). Some surfactants which comply with the above Detergents Directive are borderline when it comes to 'ready biodegradability'.

Book excerpt: River Pollution 2: Causes and Effects deals mainly with the causes of river pollution and the nature of the various kinds of pollution and their effects upon rivers. This book is an updated version of the first eight chapters of Aspects of River Pollution (first published early in 1957). Owing to the rapid development of the subject and the ever-increasing amount of literature devoted to it, some sections have been virtually rewritten, much new matter has been added, and minor alterations made throughout the text. This book begins with a review of the long history of river pollution, which can be traced back to ancient civilizations. Separate chapters deal with legal aspects of river pollution; the nature and effects of river pollution; the causes of river pollution; and uses of river water. Subsequent chapters cover the biochemical and physicochemical aspects of river pollution; the impact of river pollution on fishes; and biological aspects of river pollution.
