Abstract

Present work aimed to assess the impact of pyrogenic effect on the flora, and quality and health of soils of the Utrish Reserve. Studies performed on the territory of reserve within a month after the fire revealed that the areas showed varying degrees of damaged characteristics due to catastrophic fire. The entire damage was recorded in a 40-hectare region, while the vegetation on another 26 hectares of the reserve was damaged to a lesser extent. In total, 4,800 trees were eliminated, 73% of them belonged to rare and endangered species, such as Junipers (Juniperus spp.), Mt. Atlas mastic trees (Pistacia mutica), and Pitsunda pines (Pinus brutia var. pityusa). In the areas of severe disturbance, the soil surface was covered with a constant layer of ash two weeks after the fire.  As a result, there was an increase in the pH values, and the chemical composition of brown soil (Cambisol) was determined after the fire. There was also an increase in the organic carbon content and peroxidase activity. Catalase activity, which is sensitive to pyrogenic effects, decreased in all soil samples obtained at post-pyrogenic areas. The effect of fire on the biological state of soils may diminish over time, however, the restoration of the damaged ecosystems may take hundreds of years. The results of this study can be used in assessing the damage to ecosystems after the wildfires, as well as in developing methods to accelerate the restoration of soils after a fire impact.

Abstract

Nanoparticles are increasingly used in many industrial fields because of their special properties. In this context, several questions arise related to possible negative consequences associated with nanoparticle (NPs) entrance into the ecosystem.  The adsorption of NPs by soil can adversely influence its biological properties. In the present article, the influence of Cu, Zn, and Ni NPs on the biological characteristics of Arenosol is considered. Research aimed to study the effect of Cu, Zn, Ni NPs on the biological characteristics of sandy loam chernozem. Copper, Zn, and Ni NPs were added to the soil in concentrations of 100, 1,000, and 10,000 mg kg-1. The effect of NPs on the biological properties of Arenosol was evaluated after 10-day incubation. The biological indices of the ecological condition of the soil, including the germination of radish, the length of the roots, the bacteria population, Azotobacter sp. count, the catalase activity, and dehydrogenases were studied. As a result of this study, it was revealed that the degree of indices changes depending on the concentration of Cu, Zn, and Ni NPs in the Arenosols. Microbiological characteristics (bacteria population, and Azotobacter sp. count) and phytotoxic feature (length of roots and radish germination) properties were most sensitive to contamination compared to the enzyme activity of Arenosol. Based on the soil integral index of a biological state, the strongest inhibitory effect on biological parameters of Arenosols relative to the control was exerted by Cu NPs (lower than control by 48-72%), while the greatest stability in Arenosol was found for Ni NPs (lower than control by 30-55%). The studied biological parameters allow characterizing the severity of nanoparticle exposure on Arenosols. Early diagnostics of the severity of soil contamination by NPs can be successfully used to quickly assess their impact on the soil condition and prevent possible adverse consequences.
