How is chemistry used in toxicology?

Toxicology includes the study of chemical properties and how they affect the body. It focuses on the adverse effects of chemicals in living organisms that come in contact with them. Toxicology includes the detection, symptoms, pathogenesis, mechanism and treatment of these chemicals.

What is the study of poison?

Toxicology is the study of how natural or man-made poisons cause undesirable effects in living organisms.

Which one is used as poison catalyst?

How do poisons enter the body?

Poisons enter the body by four main routes: by being swallowed. by being inhaled. by being absorbed through the skin.

Is toxin A poison?

In science, a toxin is often considered a specific type of poison – a poisonous substance produced within living cells or organisms. Some scientists, though, refer to toxins as they would any poison and call those toxins that have a living source ‘biotoxins’ or ‘natural toxins’.

What is organic poison?

Organic poisons, on the other hand, are frequently developed within the plant in the ordinary course of metabolism. When this occurs they do not appear to function as poisons, but enter in some way into the economy of the plant.

Which medicine is used for poison?

activated charcoal – sometimes used to treat someone who’s been poisoned; the charcoal binds to the poison and stops it being further absorbed into the blood. antidotes – these are substances that either prevent the poison from working or reverse its effects. sedatives – may be given if the person is agitated.

  • Chlorine – Inhalation of chlorine at concentrations in excess of 1000 ppm is usually fatal.
