Toxicology

Toxicology, toxicology and its effects, especially on life systems. Since many substances are known to be toxic to life (whether plants, animals or microorganisms), toxicology has a wide range of overlapping biochemistry, histology, pharmacology, pathology and many other fields It is a field.

The study and classification of toxic substances was first organized by Matthieu Orfila (1787-1853) in the 19th century. Traditionally, toxicologists have been responsible for identifying poisons and looking for antidotes and other ways to treat addictive injuries. There is a long history in areas related to ancient toxicology, forensic toxicology, and poisoning criminal activity. However, with the increase of new toxic substances, the practical application of toxicology is increasing. In ecological science, toxicologists play a role in identifying and removing environmental pollutants. Assessment of occupational exposure to hazardous substances is another aspect of toxicologist's work. In the United States, toxicologists are working with the Food and Drug Administration of the Federal Government to try to identify potential hazards to public health in chemical additives in foods and cosmetics, and along with pharmacologists, We are working on the safety test of.

Probably the biggest expansion field is toxic waste research. Environmental toxicology became very important as toxic waste from various industrial processes contaminates air, water and soil and causes many unprecedented and often undetectable dangers (for the general public) . Problems of concern to global toxicologists and scientists include the use of chlorofluorocarbon (which affects the ozone layer in the atmosphere), the effect of acid rain on the world's forests, and the effects of soil, groundwater, ocean, air Contains release of harmful radioactive material to the environment.

Forensic toxicology is the use of toxicology and analytical chemistry, pharmacology and other fields such as clinical chemistry, to support medical or legal investigations of death, addiction and substance abuse. The main focus of forensic toxicology is the acquisition and interpretation of the results, not the toxicological investigation or legal result of the technology being used. Toxicological analysis can be performed on various samples. Forensic toxicologists should understand the background of the investigation, in particular all the physical symptoms that have been recorded, as well as any evidence collected at crime scenes that may narrow down the survey (vials, powders, trace residues and available chemicals etc. ) Must be considered. Forensic toxicologists provide this information and sample for use and must decide which toxic substances are present, their concentrations, and the possible influence these chemicals have on the human body not.

The field of forensic toxicology includes three major sub-fields of postmortem forensic toxicology, human behavioral toxicology and forensic examination. These specialties offer a variety of exciting career paths. Autopsy In forensic toxicology, forensic toxicologists work with pathologists, consultants, and coroners to identify the role of alcohol, drugs, and toxins in the cause of death. Forensic Toxicology Laboratory identifies and quantifies the presence of fluids and chemicals in body fluids and tissues that are removed from body fluids during necropsy. In the autopsy toxicity test, various specimens such as blood, urine, vitreous humor from the eyeball, liver, brain, other tissues, and also hair and nails can be found. Once the test is completed, forensic toxicologists will explain the findings. This information will help forensic pathologists identify causes and causes.

Postmortal forensic toxicology involves analysis of fluids and toxins in body fluids and tissues collected from victims of suspicious circumstances. Postmortal forensic toxicology is an important part of the death investigation to provide information to address the following questions and problems. (1) What drugs and toxins are present in the body? (2) Is the concentration of drug or toxin within the critical range? (3) Does the medicine cause damage of a fatal accident?
