The research results described prove the existence of health injury to the population, living in the areas of exposure to oil storage and transfer objects on the basis of in-depth biomedical research. It is shown that the presence in the blood of children living in the area of the objects' exposure to specific chemical contaminants (benzene, toluene, ethyl benzene, phenol, formaldehyde) was significantly associated with the development of processes connected with toxic metabolites' intoxication and accumulation, cellular immunity activation, damage to the liver cells' membranes, cell regulatory mechanisms' destabilization, regardless of age.
