Toxicology and Drug Testing

Toxicology and Drug Testing is a comprehensive academic textbook that explores two vital scientific fields: toxicology—the study of poisons, and drug testing—the detection of substances in biological systems. Designed for students, educators, and professionals in medical, pharmaceutical, forensic, and environmental sciences, the book presents a well-structured, in-depth, and theoretical approach to both disciplines. The text begins with foundational toxicology principles, including classifications of toxicants, dose-response relationships, and the physiological and biochemical factors affecting toxicity. It then delves into mechanisms of toxicity, explaining how toxicants induce oxidative stress, disrupt cellular balance, and damage genetic material. Organ-specific toxicology is explored in detail, highlighting how toxins impact vital organs like the liver, kidneys, heart, brain, and lungs. Environmental and occupational toxicology are also emphasized, addressing real-world exposures to heavy metals, pesticides, and pollutants. Forensic and clinical toxicology sections focus on practical aspects such as poisoning diagnosis, analytical techniques, and the legal implications of substance misuse. The drug testing component covers collection methods, immunoassays, chromatographic techniques, and emphasizes quality control, ethical considerations, and legal compliance. A unique strength of the book is its focus on global regulatory standards, toxicological risk assessment, and ethical laboratory practices. Clearly organized and scientifically rigorous, Toxicology and Drug Testing supports independent learning and critical thinking, making it an essential resource for understanding and managing toxicological risks across various professional settings.
