    Note: The first book of its kind, devoted exclusively to the assessment of DNA damage by the Comet assay in modern toxicology, The vast number of chemicals existing or being added into the environment, have globally aroused great concern regarding their adverse effects in human population. Development and validation of sensitive and better test systems which can assess the adverse effects of chemicals at an early stage for intervention strategies to be implemented in time is currently in progress. This book documents the latest research and showcases the versatile, state-of-the-art technique - the Comet assay - in the field of modern toxicology. The assay is a simple, sensitive rapid and visual technique for the quantitative and qualitative assessment of DNA damage in single cells. The Comet Assay in Toxicology is the first book of its kind to be devoted exclusively to the Comet assay and its applications as an important tool in modern toxicology. This multi-author book will serve as both a reference and a guide to investigations in the biomedical, biochemical and pharmaceutical sciences. Written by investigators from the fields of genetic toxicology and human epidemiology, the authors have first-hand knowledge from their chosen sub-specialities and are active contributors to the peer-reviewed scientific literature. The book is divided into five major sections, reflecting the range of interest in the exploitation of this assay. The book's scope begins with an introduction section reviewing its genesis for those new to the technique and the current knowledge of the various fields in which it finds wide acceptance. This section sets the scene by explaining why the assay has become the most sensitive and sought after assay in modern toxicology. Next is a whole section that considers various procedures being followed to assess different types of DNA damage in various cell t++ , ypes and is contributed by experts in the respective fields. The third section puts together the specific applications of the assay in the diverse fields ranging from genetic toxicity testing to human monitoring, and environmental toxicology. The fourth section consists of the guidelines and recommendations for the conduct of the assay in in vitro and in vivo systems, based on the recommendations of the International Workgroups on genotoxicity test procedures. Finally, the book draws to a close with an assessment of the statistics used for the understanding of the data generated by the assay. This is a unique reference book as it provides the scientific community with the advances in Comet assay as well as its applications. It also incorporates a detailed section with instant and comprehensive information on the procedure of the assay and the latest protocols being used worldwide as well as statistical analyses to be followed. The book is aimed at students as well as scientists in the area of molecular epidemiology and genetic toxicology

    Note: vi Williamsburg, Virginia, February 21-23, 1978. This symposium was sponsored by the U. S. Environmental Protection Agency, Office of Energy Minerals and Industry, Washington, DC, and Office of Health and Ecological Effects, Health Effects Research Laboratory, Biochemistry Branch, Research Triangle Park, NC. The symposium consisted of 24 formal presentations that amplify the three major topics discussed during the symposium: an overview of short-term bioassay systems; current methodology involving the collection and chemical analysis of environmental samples; and current research involving the use of short-term bioassays in the fractionation and analysis of complex environmental mixtures. The purpose of this symposium was to present the state-of-the-art techniques in bioassay and chemical analysis as applied to complex mixtures and to foster continued advancement of this important area. Complex mixtures discussed include ambient air and water, waste water, drinking water, shale oil, synthetic fuels, automobile exhaust, diesel particulate, coal fly ash, cigarette smoke condensates, and food products. It is our hope that this volume will serve as a reference to catalyze and encourage further research in this field. Michael D. Waters, Ph. D. Stephen Nesnow, Ph. D. vii Acknowledgment We would like to thank Gerald Rausa, Office of Energy Minerals and Industry, for his advice, encouragement, and support of this program. We would also like to express our appreciation to Wendy A. Martin, Peter A. Murphy, and David F. Wright of Kappa Systems, Inc

    Note: Contained in this volume are the proceedings of the international conference on the "Genetic Toxicology of Complex Mixtures," held from July 4-7, 1989, in Washington, DC. This meeting was a satellite of the "Fifth International Conference on Environmental Mutagens" and the seventh in a biennial series of conferences on "Short-term Bioassays in the Analysis of Complex Environmental Mixtures. " Our central objective in calling together key researchers from around the world was to extend our knowledge of the application of the methods of genetic toxicology and analytical chemistry in the evaluation of chemical mixtures as they exist in the environment. This conference emphasized the study of genotoxicants in air and water, and the assessment of human exposure and cancer risk. The latest strategies and methodologies for biomonitoring of genotoxicants (including transformation products) were described in the context of the ambient environment. Source characterization and source apportionment were discussed as an aid to understanding the origin and relative contribution of various kinds of complex mixtures to the ambient environment. Similarly, investigations of genotoxicants found in the indoor environment (sidestream cigarette smoke) and in drinking water (chlorohydroxyfuranones) were given special attention in terms of their potential health impacts. New molecular techniques were described to enable more precise quantitation of internal dose and dose­to-target tissues. The emphasis of presentations on exposures/effects assessment was on integrated quantitative evaluation of human exposure and potential health effects

    Note: In the four years since the 1978 Symposium on the Application of Short-Term Bioassays in the Fractionation and Analysis of Complex Environmental Mixtures the use of short-term bioassays to evaluate potential health hazards of complex environmental mixtures has substantially increased. Increased research activity has been particularly noticeable in mobile source emissions, where initial observations on the mutagenic activity of diesel particulate extracts reported at the 1978 symposium stimulated the development of major research programs in government and industry. In the absence of appropriate reference materials, the U.S. Environmental Protection Agency initiated comparative genotoxicity studies to determine the relative mutagenic and carcinogenic activity and, ultimately, the potential human health risk due to exposure to various complex emission products. Among the materials investigated were those of known health risk, such as coke oven and roofing tar emissions and cigarette smoke condensates, and those of unknown hazard, such as exhaust from diesel-and gasoline-powered vehicles. Studies on diesel emission products proved useful in short­ term bioassay development, as the diesel exhaust extracts were genetically active with low cellular toxicity and could be obtained in relatively large quantities. Availability of such samples aided chemical characterization, and it was eventually determined that the nitro-polynuclear aromatic hydrocarbons were among the mutagenic components of diesel exhaust particulate

    Note: With this proceedings of the fourth symposium on complex mixtures, we continue to revise and extend our knowledge of genetic methods for the evaluation of chemical mixtures in the environment. The early chapters of this volume are devoted to new bioassay techniques that are directly applicable to the monitoring of environments contaminated with genotoxic chemicals. Microbiological methods have been further refined to meet the special needs of atmospheric monitoring so that very small samples may now be efficiently tested. New in situ methods utilizing green plants actually avoid many of the usual difficulties of sample collection and preparation and offer special advantages in monitoring wastewater, sludges, and hazardous wastes. Insects also are being employed very effectively in the evaluation of gaseous air pollutants in controlled laboratory investigations. Increased emphasis has been placed on a comprehensive assessment of the potential of complex mixtures t9 cause various kinds of genetic damage. New assays for chromosome structural and numerical aberrations in mammalian cells in vitro have been developed and are being applied in laboratory studies. Efforts to link tests for gene mutation and cell transformation in vitro with assays for tumorigenesis in vivo are contributing to the validation of the short-term testing approach. Studies comparing in vitro and in vivo data on a coal conversion by-product, on polycyclic aromatic hydrocarbons, and on mineral fibers are reported in separate papers. Later chapters are devoted to investigations on the fractionation and biological evaluation of specific chemical components within complex mixtures
