Abstract |
The study of the concentration of trace metals in soils by atomic absorption analysis was carried out.
The results indicate the transformation of their migration properties. The diversity and versatility of behavior of
chemical elements in environmental components after the fire was noted. In different ecological conditions, it is possible
to observe a wide range of quantitative values of geochemical migration or accumulation of any particular
chemical element. Analytical results show that the contents of migrant elements, pH values, areas of incidents, which
are approximately in the same conditions, but passed by the grass or upper fire differ quite tangibly. Trace metals that
hit the environment can form difficult soluble hydroxides. In addition, in the soil solution, there is a probability of the
formation of hydroxocomplexes with different amounts of hydroxide ions by metals. The range of precipitation of
hydroxides and the region of predominance of soluble hydroxocomplexes have been studied by constructing concentration-
logarithmic diagrams. On the basis of the calculations it can be argued that the influence of the technogenic
loading of pyrogenic origin on the geochemical migration of trace metals takes place. The obtained calculations can
be used to predict the geochemical migration of trace metals in soils after the man-made consequences of emergencies
of pyrogenic origin. Відзначено різноманітність поведінки хімічних елементів у довкіллі після ураження пожежами. Створено прогнозування геохімічної міграції сполук міді у грунтах після пірогенного впливу. |
