[Studies of the dependence of alkoxycyanodiphenyl toxicity on structure with the aim of health-related group standardization]. 
The article presents results of toxicity and hazard effects studies of alcoxicyandiphenyl CnH2n+ 1OC12H8CN with n = 1-8, octilcyandiphenyl and octildiphenyl.  Toxicity parameters were established in animal tests and on isolated mitochondria, and inhibiting concentrations were calculated.  Correlation was established between the alcoxicyandiphenyl detainment in high-performance liquid chromatography and the inhibition rate constant.  The allowable and hazard levels are also specified.
