toxicology Toxicology is the study of chemical substances (including drugs, environmental pollutants and industrial chemicals, etc.) the harmful effects of the application of discipline. Is the study of toxic effects of chemicals on organisms, severity, frequency of occurrence and toxicity mechanisms of science, but also on the toxic effects of qualitative and quantitative evaluation of science. Predict harm to humans and the environment, in order to determine the safety limits and to take preventive measures to provide a scientific basis for discipline. The main application of physiology, pharmacology, biology, biochemistry and pathology and other basic theory and technology disciplines; through animal experiments, clinical observation and epidemiological methods to study the absorption of foreign substances, distribution, metabolism and excretion, toxicity its mechanisms and treatment of poisoning, not only for the protection of humans and other organisms from the harmful effects of chemical substances to protect people's health, but also a good choice for the development of the direct effect of the poison, poison by comparing the toxicity and _select_ion method, developed more _select_ive drugs and pesticides, and chemical safety assessment or risk assessment, the development of health standards, and provide scientific basis. Toxicology and Pharmacology closely related, has developed into an independent discipline has some basic theoretical and experimental methods, and gradually formed a new branch of toxicology. Toxicological currently accepted definition of exogenous chemical substances harmful organisms science. Because toxicology research purposes is to provide a scientific basis for the protection of health or safety of a biological discipline, and therefore belong toxicology from the disciplinary nature of Preventive Medicine, through the prevention ideas. Due to the extensive toxicology study, including chemical factors, physical factors, biological factors, and organisms, including humans, animals, plants, and therefore toxicology and pharmacology, physiology, pathology, chemistry, biochemistry, biology associate; and industry, agriculture, economy linked; and forensic science, clinical medicine, ecology and environmental protection have contact; can say it with the entire future of life on Earth are linked. Thus, toxicology are widely used in clinical medicine, pharmacy, environmental protection, zoology, prenatal and postnatal care, occupational health and other labor protection and food areas. Therefore toxicology classification is very complex, can be classified from different angles, not entirely consistent. Toxicology Category: From the research can be divided into: descriptive toxicology, mechanisms of toxicology and management Toxicology (also known as regulatory toxicology) in three parts. From accordance with the standard disciplines can be divided into: forensic toxicology, clinical toxicology, management or regulatory toxicology toxicology, toxicology studies. Toxicology from the application can be divided into: food toxicology, industrial toxicology, pesticide toxicology, military toxicology, radiation toxicology, environmental toxicology, ecotoxicology and other branches. From the study can be divided into: insect toxicology, veterinary toxicology, human toxicology and plant toxicology. From the research can be divided into: Drug toxicology, environmental toxicology, food toxicology, industrial toxicology, clinical toxicology, forensic toxicology, analytical toxicology, military toxicology, toxicology management. From the study of the target organ or system can be divided into: Organ toxicology, toxicology liver, kidney toxicology, toxicology eyes, ears toxicology, neurotoxicology, reproductive toxicology, immunology toxicology, skin toxicology, blood toxicology and so on. From the study of the mechanism can be divided into: cell toxicology, genetic toxicology, film toxicology, biochemical toxicology, molecular toxicology. When poison effect from phase or process can be divided into: toxicokinetics and toxic effects dynamics.
