parathion

Parathion is an organophosphorus pesticide. Organophosphorus substances are substances that block the enzyme responsible for the degradation of acetylcholine (Ach). Parathion, as such, fails to interact with the enzymatic site of acetylcholinesterase, so it needs activation or bioactivation by liver enzymes, to become Paraoxon

Carbon tetrachloride or Freon 10

Once bioactivated, carbon tetrachloride (CCl4, a complex and in itself not very toxic molecule), leads to a chain of events and to the formation of numerous toxic compounds. This molecule is also known as FREON 10 . The Freon 10 was used in the past as a component in the liquid of fire extinguishers, in refrigerators, in air conditioners, in stain removers and in dry cleaning

Toxin, Toxic and Intoxication

Introduction to toxicology As with pharmacology, toxicology is also divided into toxicokinetics and toxicodynamics ; therefore all the theory made for the drug can very well be transferred to the study of the toxic substance. In this section of the site we will focus mainly on biotransformations, because it is precisely these reactions that generate toxic substances within our body
