pdf  Kinds of impact of potentially toxic elements-admixtures in hydrocarbons on the environment
A list of toxic elements-admixtures in hydrocarbon compounds is given. Their negative impact on biota in raw material utilizing when they become free and can contact with biota is shown. Their impact on the environment may be obvious or concealed, momentary or long-term up to the historical terms of dispersion. The technological cleaning of polluted areas is not profitable. It is necessary in proper time to detect them in the composition of raw material of products processed and to provide the decrease of their blowouts.

Key words: admixtures of toxic elements in hydrocarbons, contamination of environment and its protection.

pdf  Deep zoning in concentration of heavy elements-admixtures in hydrocarbons
Distinction in composition of heavy elements-admixtures containing in hydrocarbons in depending on the depth of hydrocarbon pools is shown. Hydrocarbon pools at depths of to 3 km are frequently enriched in such admixtures of heavy metals as V, Co, Ni and others, connected with resin-asphaltenes fractions. At great depths (>4.5 km), particularly in the zones of young troughs with activated mantle, they quite often contain such the most volatile and toxic elements as Cd, Hg, As, Tn, Se, Mo and others being the products of mantle emanation. Therefore consideration must be given to their impact on the environment.

Key words: deep zoning, elements-admixtures in hydrocarbons, mantle emanation
