The Behavior of Chemical Elements in the Forest Grass-Roots Fires (Altai Territory)
Studying the behavior of chemical elements at the ground fire in 2011 near the village of Bayevo (Altai Territory) allowed them to identify two groups, the opposite of their reaction to the high temperatures of a forest fire: the first group consists of the elements involved in atmospheric emissions (Hg, Cd, Mn, Zn and 137Cs), the second – in the area of accumulating conflagration (of Fe, Al, K, Na, Co, Ni, Pb, Cu, Ba, Sr, Mg, V). Behavior of elements in a fire conducted by comparing their average content in the “background space / conflagration”. Sampling conducted steel ring (50 mm diameter 84 mm). Analytical studies were conducted gamma spectrometry and atomic absorption methods on the device SoolarM6 with Zeeman and deuterium background corrector. After the fire, the density and pH of the soil increased. Comparison of the boiling point of elements with indices of atmospheric removal / accumulation in the conflagration gave reason to bring one rule: the lower the boiling point of the element, the higher the probability of its migration in plume composition, and conversely, the higher the boiling point of the element, the more likely it passive accumulation in the area burned. However, this general rule is complicated biogeochemical properties of the elements.
