Aktuelle Grenzwerte für chemische, biologische und physikalische Einwirkungen am Arbeitsplatz liefert die soeben erschienene Neuauflage der Grenzwerteliste 2019 (IFA Report 2019) des Instituts für Arbeitsschutz der Deutschen Gesetzlichen Unfallversicherung (IFA). Sie bietet ein Nachschlagewerk für die betriebliche Praxis, um arbeitsbedingte Belastungen von Beschäftigten zu beurteilen. Neben staatlichen Vorschriften und Regeln existieren für bestimmte Einwirkungen nur arbeitswissenschaftliche Erkenntnisse oder Hinweise in Normen oder in Veröffentlichungen ausländischer Stellen. Vor allem kleine und mittlere Betriebe haben oft Schwierigkeiten, sich hier einen Überblick zu verschaffen. Hilfe bietet seit vielen Jahren die Grenzwerteliste des IFA. Neben Gefahrstoffen behandelt sie biologische Einwirkungen am Arbeitsplatz sowie Lärm, Vibrationen, thermische Gefährdungen, Strahlung, Elektrizität und biomechanische Belastungen. Die Liste enthält alle aktuell geltenden Grenzwerte, sofern sie für die jeweilige Belastungsart verfügbar sind. Fehlen Grenzwerte, finden sich Empfehlungen und Erläuterungen zur Arbeitsplatzbeurteilung. Komplett überarbeitet wurden der Abschnitt „4.1 Ionisierende Strahlung“ und die Tabellen im Kapitel „Gefahrstoffe in Innenräumen“.

Machine drives using closed-loop speed control are state of the art. As on drives without closed-loop speed control, the movement of a machine part at varying speeds frequently gives rise to a hazard against which the machine operators must be protected. The simplest means of preventing movements during manual intervention in danger zones is the (safe) disconnection of the energy driving the relevant motors. This is however often not possible, for example when intervention is required whilst the machine is running for the purpose of clearing faults, setup, during test operation, etc. Scenarios such as these require the machine to be operated with protective equipment disabled. In order for the operators‘ safety to be assured nonetheless, Annex I, Section 1.2.5 of the Machinery Directive sets out the required measures. Safety sub-functions for drive controls have been defined for implementation of the machine functions required for this purpose. Examples are STO (safe torque off), SLS (safely limited speed) and SS1 (safe stop 1). This report addresses the use of drive control equipment that implements safety sub-functions at a certain Performance Level according to ISO 13849-1 in consideration of the application and risks. The basic safety sub-functions of drive controls and the requirements relating to their use are presented. The principles of operation of frequency inverters and DC converters are described, and implementation of the safety sub-functions are explained. Examples are provided of application circuits by which the various machine safety functions can be implemented. The corresponding SISTEMA files for quantification of these safety functions are available for download free of charge. The examples include both standard frequency inverters and frequency inverters with integrated safety functions.

Ten years after coming into force of the Stockholm Convention on Persistent Organic Pollutants (POPs), a wide range of organic chemicals (industrial formulations, plant protection products, pharmaceuticals and personal care products, etc.) still poses the highest priority environmental hazard. The broadening of knowledge of organic pollutants (OPs) environmental fate and effects, as well as the decontamination techniques, is accompanied by an increase in significance of certain pollution sources (e.g. sewage sludge and dredged sediments application, textile industry), associated with a potential generation of new dangers for humans and natural ecosystems. The present book addresses these aspects, especially in the light of Organic Pollutants risk assessment as well as the practical application of novel analytical methods and techniques for removing OPs from the environment. Providing analytical and environmental update, this contribution can be particularly valuable for engineers and environmental scientists.

This volume contains a series of papers originally presented at the symposium on Water Soluble Polymers: Solution Properties and Applications, sponsored by the Division of Colloids and Surface Chemistry of the American Chemical Society. The symposium took place in Las Vegas City, Nevada on 9 to 11th September, 1997 at the 214th American Chemical Society National Meeting. Recognized experts in their - spective fields were invited to speak. There was a strong attendance from academia, g- ernment, and industrial research centers. The purpose of the symposium was to present and discuss recent developments in the solution properties of water soluble polymers and their applications in aqueous systems. Water soluble polymers find applications in a number of fields of which the following may be worth mentioning: cosmetics, detergent, oral care, industrial water treatment, g- thermal, wastewater treatment, water purification and reuse, pulp and paper production, sugar refining, and many more. Moreover, water soluble polymers play vital role in the oil industry, especially in enhanced oil recovery. Water soluble polymers are also used in ag- culture and controlled release pharmaceutical applications. Therefore, a fundamental kno- edge of solution properties of these polymers is essential for most industrial scientists. An understanding of the basic phenomena involved in the application of these polymers, such as adsorption and interaction with different substrates (i. e. , tooth enamel, hair, reverse - mosis membrane, heat exchanger surfaces, etc. ) is of vital importance in developing high performance formulations for achieving optimum efficiency of the system.

Surfactants and Interfacial Phenomena Milton J. Rosen Bridging the gap between purely theoretical aspects of surface chemistry and the purely empirical experience of the industrial technologist, this book applies theoretical surface chemistry to understanding the action of surfactants in modifying interfacial phenomena. It surveys the structural types of commercially available surfactants and discusses interfacial phenomena, the physicochemical principles underlying the action of surfactants in each phenomenon, and the effect of structural changes in the surfactants and environmental changes on their action. Tables of data on various interfacial properties of surfactants, compiled and calculated from the latest scientific literature, are included. 1978 304 pp. An Introduction to Clay Colloid Chemistry, 2nd Ed. H. van Olphen This book provides valuable guidance in research and design efforts by giving a clear understanding of principles and concepts of colloid chemistry as applied to clay systems. Updated and enlarged, this edition includes new information on surface characterization and adsorption mechanisms; recent results in the area of clay-organic interaction--the intercalation and intersalation of kaolinite minerals; and increased attention to the possible role of clays in biological evolution. 1977 318 pp. Physicochemical Processes for Water Quality Control Walter J. Weber, Jr. Focusing on physicochemical rather than biological processes, this book presents a comprehensive treatise on the treatment of municipal and industrial water and wastewater. All of the physicochemical processes important to municipal and industrial water and wastewater treatment--coagulation, filtration, membrane processes, chemical oxidation, and others--are included and each is covered thoroughly from principle through application. To maintain a high level of expertise, contributions have been incorporated from specialists actively involved in research or engineering applications in each area considered. 1972 640 pp.
