A organochlorinated compound is chemicals of synthesis, derived from molecules of Chlore and used like Solvant, Pesticide, Insecticide, Fongicide or Réfrigérant or intermediate molecules of synthesis in Chimie and Pharmacie.

Most known are the Pesticide S (DDT, aldrin, kepone, dieldrin, chlordane, heptachlore, endrin, mirex, BPC, Toxaphène, Lindane…), PCB and the Dioxane S.

They are important contaminants of the ecosystem S and the principal problem is which they are extremely stable. The majority of them belong to the persistent Polluants organics. They do not break up before decades, and in certain cases, of the centuries….

At the time when the Dieldrine was interdict in 1974, the Food and Drug Administration found some in 96% of the Viande, the Volaille and the Poisson consumed to the the United States, in 85% of the dairy products and the flesh of 99,5% of the Americans.”
