Toxicology (from the Ancient Greek words τοξικός toxikos "poisonous" and λόγος logos) is a branch of biology, chemistry, and medicine (more specifically pharmacology) concerned with the study of the adverse effects of chemicals on living organisms. It also studies the harmful effects of chemical, biological and physical agents in biological systems that establishes the extent of damage in living organisms. The relationship between dose and its effects on the exposed organism is of high significance in toxicology. Factors that influence chemical toxicity include the dosage (and whether it is acute or chronic); the route of exposure, the species, age, sex and environment.
Dioscorides, a Greek physician in the court of the Roman emperor Nero, made the first attempt to classify plants according to their toxic and therapeutic effect.Ibn Wahshiyya wrote the Book on Poisons in the 9th or 10th century. This was followed up in 1360 by Khagendra Mani Darpana.
Mathieu Orfila is considered the modern father of toxicology, having given the subject its first formal treatment in 1813 in his Traité des poisons, also called Toxicologie générale.
Toxicology depends on variables such as dosage and routes of experience. To learn more about the Flinn Scientific Laboratory Safety Training Course visit us at: http://labsafety.flinnsci.com/Home.aspx

Go to www.emboards.com to attend the live course or purchase the self study video! The National Emergency Medicine Board Review was created for one reason - to assist physicians in passing their exams. This objective drives the content of the course. The focus is on "bread and butter" emergency medicine that is neither controversial nor "leading edge." You won't hear anything about the specifics of whether TPA should or should not be given for strokes, but rather your valuable time will be focused on the core content of emergency medicine. You'll find emphasis on important topics that you may not routinely encounter in day-to-day emergency care, but which are still "must know" for the exams, including - toxicology syndromes, pediatric rashes, recognition of specific stroke presentations,...
“Toxins and Toxicology” - a presentation by Ann Arens, MD on May 21, 2015. We live in a polluted world. Toxic chemicals are added to our food, our household products, and body care products.
