Biomarkers are biochemical indicators that can be used to monitor biological changes in response to toxins or other stimuli. Researchers can measure and predict toxicological effects with the understanding that biomarkers within a biological system will fluctuate according to changes in that system. Biomarkers can help identify not only a substance’s degree of toxicity but also the mechanisms by which that substance causes toxic effects. Over the last few decades, the use of biomarkers has emerged as a valuable tool in many areas of life and health sciences, so Biomarkers in Toxicology is a much-needed resource, covering descriptions and applications of biomarkers in the field of toxicology for a wide range of research purposes. Biomarkers in Toxicology chiefly compile recent advancements and current information about biomarkers that are used in toxicology and toxicity assessment with strong organization and clear definitions throughout the book. Over 64 chapters, Biomarkers in Toxicology reviews and discusses several categories of biomarkers, including biomarkers of experimental animal models, specific organ systems and different types of toxicity and toxicological effects. These chapters are divided into eight large parts.
