It was so popular that it became firmly established in folklore and from the name of a chemical substance it turned into a nominal name. What kind of funds are hidden behind this name, can I get poisoned with dichlorvos and how can I give first aid for intoxication?

What is dichlorvos

Before considering the symptoms and treatment of dichlorvos poisoning, let's find out what modern manufacturers hide behind this trademark. Few people know that dichlorvos (DDVF) as such has been banned in Russia for a long time. This once popular insecticide, belonging to the class of organophosphorus compounds, had a number of undeniable advantages:

  • quickly acted on all kinds of insects and mites;
  • poisoned parasites by ingestion of poison, inhalation of vapors and contact action;
  • was relatively low toxic to warm-blooded animals and humans;
  • decomposed well in the environment;

All this led to the displacement of the drug by insecticides from the group of pyrethroids and at present, dichlorvos is excluded from the list of authorized pesticides.

This means that poisoning with dichlorvos vapors is unlikely, but still possible. Violation of instructions for use of insecticides leads to an accumulation of an excess dose of toxin. With a high concentration of toxin indoors, edema of the mucous membrane of the respiratory tract develops, headache due to vascular spasm, the poison enters the blood and affects the liver, destroying hepatocyte cells.
