Investigation of the influence of hyperthermia and soil pollution with the petrochemicals on test objects using the method of mathematical planning

Purpose. To increase the efficiency of using methods for assessing level soil contamination by oil products against background influence other factors. Methodology. The authors consider possibility bioassays to study impact several stressors on test system. Based theory experiment planning, a methodology researching hyperthermia and with kerosene growth parameters objects was developed. On basis obtained experimental data, regression models were built which allow finding numerical estimate stress factors changes in characteristics object. Findings. It determined that, as rule, order assess stressful when normalizing assumed levels their humans ecosystems biotesting methods, such an assessment is carried out individual But, real conditions existence plants organisms, they are exposed simultaneous many that can interact non-additively, i.e. antagonists or synergists. In use factors, applied one mathematical planning experiment. concluded effect factor depends, certain extent, factor, studied work. fact non-additive used makes it possible recommend practice monitoring condition soils technogenically loaded territories previously action hyperthermia. Originality. toxic petroleum product Pretreatment hyperthermic hormesis dose had preventive effect, increasing resistance product. Practical value. territories.
