Animal Virology consists of papers presented in a meeting which considered broad issues and advances in animal virology and tumor viruses. This book is divided into nine parts, representing the nine sessions of the meeting. Five of the nine sections deal particularly with viruses known to be oncogenic in animals, and one of these covers explicitly human oncornaviruses. The other four sections describe the processes common to all viruses: replication, protein synthesis, and persistence, wherein emphasis is given to negative strand viruses and plant viruses.
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 was...

In the laboratory, testing the toxic effects for a single compound is a straightforward process. However, many common harmful substances occur naturally as mixtures and can interact to exhibit greater toxic effects as a mixture than the individual components exhibit separately. Complex Mixtures addresses the problem of identifying and classifying complex mixtures, investigating the effect of exposure, and the research problems inherent in testing their toxicity to human beings. A complete series of case studies is presented, including one that examines the cofactors of alcohol consumption and cigarette smoke.
This volume concerns sources of polycyclic aromatic hydrocarbons (PAH), their emission factors, and relative importance. It deals with exposure, uptake, metabolism, and detection of PAH in the human body. The volume contains an update of information in environmental and biochemical studies of PAH.
The theme of this volume--risk analysis in the private sector--reflects a changing emphasis in risk analysis. Until re cently, attention has been focused on risk analyses conducted in support of federal regulatory decision making. Such analyses have been used to help set safety standards, to illuminate issues of regulatory concern, and to evaluate regulatory alternatives. As this volume indicates, however, risk analysis encompasses a broader set of activities. Analyses performed by private sector institutions aimed at preventing or reducing potential adverse health or environmental effects also play an important part in societal risk management. In virtually all societies, there have been st...
