Although poisons have been studied and written about since the ninth century, the true origin of modern toxicology goes back to the early 1800’s when a man named Mathieu Orfila produced a scientific work titled Traité des poisons: tires des règnes mineral, vegetal et animal; ou Toxicologie générale. The discripline requires high level skills in analytical techniques with a solid knowledge of pharmacology and pharmacokinetics. Toxicology involves studying the symptoms, mechanisms, detection and treatments of poisoning of a living body. <> Although the history of poisons dates to the earliest times, the study and the science of toxicology can be traced to Paracelsus (1493–1541) and Orfila (1757–1853). Analytical toxicology can assist in the diagnosis, management, prognosis, and prevention of poisoning. The aim of this study was to develop an LC-MS/MS based screening technique that covers a broad range of acidic and neutral drugs and poisons by combining a small sample volume and efficient extraction technique with simple automated data processing. Structure: The formulas are redrawn in the molefile format allowing their use in electronic databases. Toxicology studies poisons of all types, including industrial chemicals, pesticides, radioactive substances, bacterial toxins, and other poisons of inorganic, plant, and animal origin. Source. Chapters on chromatographic techniques such as thin-layer chromatography, gas chromatography (GC), high-pressure liquid chromatography and capillary electrophoresis will be appreciated by the reader for their detailed description of the techniques. endobj Chemicals, or toxic agents, may be biological, physical, or chemical. Ibn Wahshiyya wrote the Book on Poisons in the 9th or 10th century. For analytical purposes, poisons are generally divided into classes according to the methods which are used to isolate them. Drugs most commonly targeted include amphetamines, benzodiazepines, cannabis, cocaine and the opiates, but can be any other illicit substance or almost any over-the-counter or prescribed drug, as well as poisons available to the community. Toxicology is the science of poisons, embracing the physical and chemical study of all the known poisonous substances, as well as the methods of testing for them, their action on the living body, and the postmortem results they occasion. endobj It describes the cause and effect of the poison on different parts of the body when taken through the skin, injection, and oral routes. These documents list well-established methods for measuring lead and describe some of their characteristics, including their advantages and disadvantages. Systematic toxicological analysis (STA) is a major part of the examination in forensic and clinical toxicology. ? Nowadays the intentional poisoning of domestic and wild animals is a crime in the European Union (EU), but as in the past the poison is still used in rural areas of a number of European countries to kill animals that were considered harmful for human activities.
