The peculiarities of sanitary and hygienic rationing of oil products content in environmental components are analyzed. It is established that the general ecological situation in our country and abroad is unsatisfactory and the issue of finding modern methods of standardizing the quality of environmental components is becoming more urgent, which would cover indicators and criteria of their composition and properties. It together would ensure ecologically sustainable development of the biosphere in all hierarchical levels of its organization. It is established that today such an assessment system does not exist and therefore, there is no generally accepted universal method for assessing the quality of the components of the environment. To do this, it is necessary to develop a methodology, in particular a method of biotesting, which will provide a generalized qualitative assessment of the ecological state of the environment, without being based on the quantitative characteristics of the MPC. The possibility of applying of a new method of phytotesting of soil that was artificially contaminated with different types of petrochemicals in different concentrations per unit volume of soil using flax seedlings (Linum usitatissimum L.). There are presented the growth characteristics of test plants grown on artificially contaminated soil with petroleum products. In the course of research, the possibility of studying the effect of petrochemicals on plants directly in artificially contaminated soil was confirmed. Based on the analysis of the obtained results, it was found that when the soil is contaminated with oil products, aviation fuel has a greater impact on the shoots, and gasoline and diesel fuel have a lower impact on the roots in lower concentrations. At higher concentrations, their depressant effect is almost equal.
