What Does The Word Toxicological Mean?


: a science that deals with poisons and their effect and with the problems involved (such as clinical, industrial, or legal problems)

What is the root word of toxicology?

Toxicology — which is a branch of pharmacology — has to do with toxic substances (poisons). It comes from the Greek word for “arrow poison.” Not all poisons come at the end of an arrow, though.

What are toxicological studies?

Toxicology studies are used to characterize the toxicity profile of a drug by identifying its impact on organ structure and / or functionality. This includes assessment of the severity and reversibility of toxicity, as well as dose ranges and their relationship to exposure.

Are toxicologists doctors?

Medical toxicologists are physicians who specialize in the prevention, evaluation, treatment, and monitoring of injury and illness from exposures to drugs and chemicals, as well as biological and radiological agents.

What are the four major types of toxic substances?

Types. There are generally five types of toxic entities; chemical, biological, physical, radiation and behavioural toxicity: Disease-causing microorganisms and parasites are toxic in a broad sense but are generally called pathogens rather than toxicants.

How would you define toxicology?

Toxicology is a field of science that helps us understand the harmful effects that chemicals, substances, or situations, can have on people, animals, and the environment. … The dose of the chemical or substance a person is exposed to is another important factor in toxicology.

Is toxicology a chemical?

Toxicology is a scientific discipline, overlapping with biology, chemistry, pharmacology, and medicine, that involves the study of the adverse effects of chemical substances on living organisms and the practice of diagnosing and treating exposures to toxins and toxicants.

What are the three types of toxicology?

There are various types of toxicology as outlined below:

  • Analytical toxicology.
  • Applied toxicology.
  • Clinical toxicology.
  • Veterinary toxicology.
  • Forensic toxicology.
  • Environment toxicology.
  • Industrial toxicology.

Who is known as the father of toxicology?

Mathieu Joseph Bonaventure Orfila (1787–1853), often called the “Father of Toxicology,” was the first great 19th-century exponent of forensic medicine. Orfila worked to make chemical analysis a routine part of forensic medicine, and made studies of asphyxiation, the decomposition of bodies, and exhumation.

When was toxicology first used?

The first comprehensive work on Forensic Toxicology was published in 1813 by Mathieu Orfila. He was a respected Spanish chemist and the physician who is often given the distinction of “Father of Toxicology.” His work emphasized the need for adequate proof of identification and the need for quality assurance.

What are toxicological effects?

Toxicological effects are dependent on the concentration of chemicals within the target organ and on the duration of exposure. Several pharmacokinetic processes (absorption, distribution, metabolism, and excretion) govern chemical disposition in the nervous system.


What does ballistics mean in science?

ballistics, science of the propulsion, flight, and impact of projectiles. It is divided into several disciplines. Internal and external ballistics, respectively, deal with the propulsion and the flight of projectiles. The transition between these two regimes is called intermediate ballistics.

What is sensitivity in biology?

In biology, sensitivity is a measure for how strong a stimulus has to be, before a system reacts to it; the smaller a stimulus is sufficient to elicit a reaction, the more sensitive a system is.

How many types of toxicology are there?

The different types of toxicology are listed below: Analytical toxicology: This includes the detection and evaluation of toxic chemicals. Applied toxicology: Applied toxicology is concerned with the application of modern technology in the early detection of toxicants.

What is the pharmacology of a drug?

Pharmacology is the science of how drugs act on biological systems and how the body responds to the drug. The study of pharmacology encompasses the sources, chemical properties, biological effects and therapeutic uses of drugs.

What is the difference between toxicology and Toxinology?

Toxinology is the study of the toxins, poisons, and venoms from plants, animals, and microbes; toxicology is the study of the effects of toxins, as well as other chemical substances, on living organisms.

What does Ecotoxicologist mean?

: a scientific discipline combining the methods of ecology and toxicology in studying the effects of toxic substances and especially pollutants on the environment. Other Words from ecotoxicology. ecotoxicological -​kə-​ˈläj-​i-​kəl adjective. ecotoxicologist -​ˈkäl-​ə-​jəst noun.

What does toxicology do for us?

The fundamental purpose of Toxicology is to help us avoid chemical injury or manage accidental exposure of humans or the environment.

What the body does to drug?

Pharmacokinetics, sometimes described as what the body does to a drug, refers to the movement of drug into, through, and out of the body—the time course of its absorption.

What are natural toxicants?

Natural toxins are chemicals that are naturally produced by living organisms. … Mycotoxins are toxic chemical products formed by fungi that can grow on crops in the field or after harvest. The foods that can be affected include cereals, nuts, fruit and dried fruit, coffee, cocoa, spices, oilseeds and milk.

What is a Class 3 poison?

Toxicity category III is Slightly toxic and Slightly irritating, Toxicity category IV is Practically non-toxic and not an irritant.

What are the 6 classes of toxins?
