[Neurotoxicity of pyrethrins in warm-blooded animals].

The synthetic pyrethroids, a new class of insecticides, have excellent insecticide properties with good biodegradability, therefore a low remanence. Their mammalian toxicity is low in considering amounts used in agriculture. On the other hand, experimental animals exposed to mean so high concentrations of pyrethroids display neurological symptoms. This paper is a review relating the electrophysiological, biochemical and pharmacological aspect of the patent neurotoxicity of pyrethroids. Benign cases human intoxication and acute animal intoxication are reported.
