内容説明
New developments in the study of environmental mutagens continue to evolve in this rapidly emerging field. In Volume 7 of Chemical Mutagens, we have focused on various new techniques for the detection of genetic damage in somatic cells and germ cells of mammals and the use of lower eukaryotic microorganisms to detect aneuploidy as well as other types of genetic damage. Attention has also been given to the role of in vitro metabolic activation as a mechanism for modifying the genetic effects of different environmental chemicals. In a chapter on compar- ative mutagenesis, reaction kinetics and their relationship to the mu- tagenic action of monofunctional alkylating agents in higher eukaryotic organisms are examined. In another chapter, the pharmacology and toxicology of nitrites and nitrates, which are in widespread distribution in the environment, are discussed in detail. The books in this series have provided a mechanism for the publication of many important new developments in the study of the genetic effects of environmental chemicals. This series was launched by Dr. Alexander Hollaender who, beginning in 1971, edited Volumes 1-4 and then coedited Volumes 5-7.
The success of his lO-year effort with these volumes is another testimony to Dr. Hollaender's many contri- butions to the field of environmental mutagenesis. As Dr.

内容説明
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.

Volume 9 of Chemical Mutagens consists mainly of chapters discussing the development and validation of short-term assays to detect the mutagenic effects of environmental chemicals. These chapters include an assay with the grasshopper neuroblast, a comparison of mutagenic responses of human lung-derived and skin-derived diploid fibroblasts, a forward-mutation assay in Salmonella, a multigene sporulation test in Bacillus subtilis, a specific locus assay in mouse lymphoma cells, a study of the induction of bacteriophage lambda, and the granuloma pouch assay. In addition, there are two chapters on the identification of mutagens in cooked food and in human feces.
