Subiect of investigation. Synthetic pyrethroids II type &-cyhalothrin and cypermethrin. Chicken, potatoes, corn, root soil. Purpose of investigation. Study of toxicodynamic and toxicokinetic of &-cyhalothrin and cypermethrin. Elabor-ating the method of definition residues in animal and plant tissues. Substentiate of Maximal admissible level MAL) in animal fodder. Research methods. Hematological, biochemical, chromato-graphical, photocolorimetrical, pathomorfological and statistical. Equipment. Gas-liquid chromatograph, photocolorimeter, microscope, thermostat pH-meter. Theoretical results. Toxicodynamical and toxicocinetical peculiarity has been analysed. Find out accumulation of &-cyhalothrin an cypermethrin in lipid tissues, changes activity of ferments. Practical results. Elaborated method of definition pyre-throids, substentiate of maximal admissible level (MAL) in animal fodder. Novelty presense. Degree of introduction. Elaborated method of definition pyrethroids. Elaborated and confirma-tedby S tate department of veterinary medicine scientific-practical recommendations "Maximal admissible levels (MAL) of synthetic pyrethriods (permethrin, cypermethrin, delthamethrin, cyhalothrin, & -cyhalothrin, fenvalerat, fluvalinate) in animal fodder.
