ABSTRACT

Peculiarities of accumulation and excretion of different phosphor-organic pesticides from stomach wall at peroral introduction in LD50 dose. The data on dependence of pesticide LD50 on the rate of accumulation is stomach wall, the time of their biological lifetime, the direction of metabolism, and content of intact pesticides in liver tissues have been presented.
