A chemical element or of biological origin is known as neurotoxic if it is about a Toxine affecting to the Nervous system organizations which come into contact with him.

A neurotoxic usually acts while disturbing or of paralyzing the nerve impulse, while acting in particular on the synaptic transmitters or receivers. The result is, in a few minutes, even in a few seconds, of the sight trouble and other directions, loss of the engine control (general paralysis), possibly followed by a paralysis of the cardiac muscle and muscles of breathing, then of the Mort. Certain molecules act only on the warm-blooded animals, others on the animals with cold blood, others in both cases.

Many products usually used or produced by industry are the neurotoxic certain ones: it is for example the case of the Plomb, of the methyl mercury, the Arsenic, the Polychloro-biphenyl S (PCB) and of many Solvant S organics (Toluène), have a known neurotoxicity which affects the development. These products are active with very low dose on the fetus or the embryo with irreversible effects. Products such as manganese in certain forms, the fluorides and perchlorates are suspectés to cause disorders of the memory, behavior or delays intellectual.

When they are used by the soldiers (in the chemical weapons of the type Sarin for example), they are often létaux, but some are only Incapacitant S. The parade is protective clothing, with adapted mask, or in the event of exposure to a neurotoxic agent, the injection of an amount of Antidote in the seconds which follow the exposure. The antidotes currently most used consist of a combination of Atropine and Avizafone. A third agent antidote to be combined with the two precedents is currently under study with the Canada, it acts of a Oxime called HI-6. Certain antidotes are them-even toxic.

Sources, ways and types of exposure

The Man or the animal is exposed there via the air, water, the grounds. The neurotoxic ones arrive to the Cerveau or the nervous system after being inhaled, introduced and/or while passing directly through the skin for some. The Fetus and the Embryon are generally much more sensitive there.

Neurotoxic plants

Certain plants are neurotoxic, the such Hysope.
