Аннотация:The objective of the paper is to figure out what are COMPOSITION - Biotoxic activity and toxicPTEs and Issues of Environment effects.By using descriptive method for primary model, synthesis methods and process analysis and analysis ofdifficulties and discussion, we have already noted that in various geological, geochemical and geostructuralconditions there are different associations of potentially toxic elements-impurities in hydrocarbons. And Zones ofentry of such biotoxicants into the environment located directly near fuel and energy facilities processing andconsuming hydrocarbons raw materials, mainly fuel oils enriched with metals. Propagation range and levelsatmospheric pollution depend on the power of the source, emission conditions, time impact, meteorological,climatic, relief and other conditions
