Chemistry for Toxicity Testing presents the chemical requirements for external toxicity studies. This book is organized into four parts encompassing 18 chapters that discuss the basic chemistry considerations for toxicity testing program. It also describes the structure-activity prediction of the carcinogenicity of chemicals and the development of methods for mixing chemicals in rodent feed. Some of the topics covered in the book are the formulations of insoluble and immiscible test agents in liquid medium for toxicity testing; problems of testing commercial-grade chemicals; analysis of dosed feed samples; determination of chemical and vehicle mixtures stability; and the toxicity of inhaled chemicals. Other parts explore the methods for generation of test atmosphere and the monitoring of vapor concentration in test atmosphere. An evaluation of dosage analysis data from a problem-solving point of view is provided. The discussion then shifts to the effects of good laboratory practices on chemistry requirements for toxicity testing. The final part is devoted to the monitoring of aerosol chemicals inhalation in chambers. The book can provide useful information to chemists, toxicologists, students, and researchers.
