This book was released on 2013-03-12 with total page 1113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Frederick J. de Serres, Ph. D. Office of the Associate Director for Genetics National Institute of Environmental Health Sciences Research Triangle Park, North Carolina (U. S. A. ) 27709 The Workshop on Comparative Chemical Mutagenesis was orga nized to begin the process of problem identification and resolution concerning our needs to evaluate the data on test chemicals arising from assays for mutagenic activity on laboratory organisms. In the past, data on chemical mutagens has been generated and published in the scientific literature on a more or less random basis. Individual chemicals enjoy a brief period of "popularity" that leads to a burst of publications in the same or sometimes related assay systems. The incompleteness of the data base, in many of these cases, makes comparative mutagenesis difficult or impossible. In our attempts to compare the genetic effects of a given chemical over a wide range of assay systems, we are often interested in making quantitative as well as qualitative compari sons. To restate the first comparison: is the chemical under ques tion a weak, moderate or potent mutagen over a wide range of assay systems--or alternatively, does the level of response vary markedly? To make the second comparison, what is needed is information on the spectrum of genetic alterations produced as well as whether this spectrum is consistent over a wide range of organisms.

Download or read book Chemical Mutagens written by Frederick J. De Serr and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 8 of Chemical Mutagens covers a wide range of topics in this continuously changing field. This volume includes chapters on the detection of genetic damage in mammalian sperm both at specific loci and over the entire genome. The discussion of in vitro techniques for working with mammalian cells covers not only specific locus assays but also cellular activation systems. Another chapter extensively discusses the need for a revised protocol for the micronucleus assay. Structure activity relationships are investigated in a chapter dealing with hair dye constituents. One of the most comprehensive chapters deals with problems associated with the detection of mutagenic effects in defined human populations. Finally, there is a detailed presentation of a comprehensive study tabulating the genetic bioassay data on some known or suspected human carcinogens. In keeping with our policy of publishing important legislation in the area of chemical mutagens, we have also included the Council of the European Communities Directive of 18 September 1979.

This book was released on 1988-01-01 with total page 703 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The combination of scientific and institutional integrity represented by this book is unusual. It should be a model for future endeavors to help quantify environmental risk as a basis for good decisionmaking." â€"William D. Ruckelshaus, from the foreword. This volume, prepared under the auspices of the Health Effects Institute, an independent research organization created and funded jointly by the Environmental Protection Agency and the automobile industry, brings together experts on atmospheric exposure and on the biological effects of toxic substances to examine what is knownâ€"and not knownâ€"about the human health risks of automotive emissions.

Book excerpt: Radiation Research: Biomedical, Chemical and Physical Perspectives documents the proceedings of the Fifth International Congress of Radiation Research held in Seattle, Washington, 14-20 July 1974. While the focus of the Congress was on fundamental research, there were several well-attended sessions on the practical aspects of radiation research as it relates to radiotherapy, central station power generation by both nuclear fission and fusion, and the environment. This volume contains 126 papers organized into 31 parts. Beginning with a keynote address and a lecture on the time scale in radiobiology, the subsequent contributions cover a wide range of topics presented over several sessions. Topics discussed during these sessions include energy needs, nuclear power, and the environment; prospects for fusion power; technological applications of radiation; human radiobiology; hazards of radiation exposure relative to other environmental agents; the basic physics of the interactions of radiation with matter; particle penetration phenomena; and radiation effects in frozen media.

This book was released on 2012-12-06 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: A. N. WORDEN, D. V. PARKE AND J. MARKS THE BACKGROUND There is nothing new about the fact that chemical substances derived either from natural products or by synthetic means .. can give rise to toxicity in animals and human beings, and that they must be subjected to controls. The earliest writings speak of such toxicity and, from the times of ancient Egypt and in the Old Tes tament, controls have existed[l]. In the Middle Ages Paracelsus (1493-1541) noted that "All things are poisons, for there is nothing without poisonous qualities. It is only the dose which makes a thing a poison", and hence he stressed the importance of dose relative to toxic reactions [ 2] . Most of the early controls concentrated on substances that were to be deliberately administered to the human subject in the form of medicines. Legislation for many centuries was mainly con cerned with regulating the activities of apothecaries and physicians. The Royal College of Physicians, for example, was originally established to control the activities of physicians within London. Among the controls which it exerted was that over the use of medicinal substances. Such controls were, however, poor, based as they were on hearsay evidence of toxicity. For many centuries no means existed for the accurate determination of toxicity.
