Dominant lethal (DL) effects cause embryonic or foetal death. Induction of a dominant lethal event after exposure to a test substance (liquid, solid, vapour or gas, ...) indicates that the substance has affected germinal tissue of the test species ...
The purpose of the Dominant lethal (DL) test is to investigate whether chemical agents produce mutations resulting from chromosomal aberrations in germ cells. In addition, the dominant lethal test is relevant to assessing genotoxicity because, although they may vary among species, factors of in vivo metabolism, pharmacokinetics and DNA-repair processes are active and contribute to the response. Induction of a DL mutation after exposure to a test chemical indicates that the chemical has affected germinal tissue of the test animal. This modified version of the Test Guideline reflects more than thirty years of experience with this test and the potential for integrating or combining this test with other toxicity tests such as developmental, reproductive toxicity, or genotoxicity studies; however due to its limitations and the use of a large number of animals this assay is not intended for use as a primary method, but rather as a supplemental test method which can only be used when there is no alternative for regulatory requirements.
The in vitro mammalian cell gene mutation test can be used to detect gene mutations induced by chemical substances. In this test, the used genetic endpoints measure mutation at hypoxanthine-guanine phosphoribosyl transferase (HPRT), and at a transgene of xanthineguanine phosphoribosyl ...

Following a general update of the Genetic Toxicology TGs in 2015, the present Document was written to provide succinct and useful information to individuals unfamiliar with genetic toxicology testing, as well as experienced individuals wishing to obtain an overview of the recent changes that ...
First published in 1995: Alternative Methodologies for the Safety Evaluation of Chemicals in the Cosmetic Industry presents a categorization and collection of information available for the evaluation of safety using in vitro techniques. It offers a comprehensive and complete look at the entire field. In doing so, the author provides the foundation for the next phase of significant growth for this discipline.
The evolution of toxicology testing finds its impetus in the continuing growth of the chemical and pharmaceutical industries, as well as the awareness of public health initiatives, needs, and responses that demand faster, more accurate, more economical methods for screening potential toxicity. Concurrent advances in biotechnology enable viable in v
Providing a concise, yet comprehensive, reference on all aspects of industrial exposures and toxicants; this book aids toxicologists, industrial hygienists, and occupational physicians to investigate workplace health problems. • Updates and expands coverage with new chapters covering regulatory toxicology, toxicity testing, physical hazards, high production volume (HPV) chemicals, and workplace drug use • Includes information on occupational and environmental sources of exposure, mammalian toxicology, industrial hygiene, medical management and ecotoxicology • Retains a succinct chapter format that has become the hallmark for the previous editions • Distils a vast amount of information into one resource for both academics and professionals
The OECD Guidelines for the Testing of Chemicals are a collection of internationally agreed methods for testing the safety of chemicals and chemical preparations, including pesticides and industrial chemicals. This 2005 update contains 11 new and 3 revised guidelines.
