The term “substance” is almost always synonymous with “chemical” and includes drugs, vitamins, pesticides, pollutants, and proteins. Even radiation is a toxic substance.
What makes a chemical poison?
What makes a chemical toxic? The toxicity of a substance is its ability to cause harmful effects. These effects can strike a single cell, a group of cells, an organ system, or the entire body. A toxic effect may be visible damage, or a decrease in performance or function measurable only by a test.
What is the science of poison called?
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.

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.

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.

- Hydrogen sulfide – In high enough concentrations, inhaling this gas results in a coma and death.
- Arsine – This gas attacks the hemoglobin in your red blood cells.
- Chlorine – Inhalation of chlorine at concentrations in excess of 1000 ppm is usually fatal.
