Environmental impact of the launch vehicle "Soyuz-FG" emergency falling in Kazakhstan.

On October 11, 2018, in the Ulytau region of the Republic of Kazakhstan, the Soyuz-FG launch vehicle carrying a crewed MS-10 spacecraft failed. It resulted in the release into the fragile arid ecosystems of rocket propellants, i.e.

Data on the temporal changes in soil properties at the emergency crash site of the launch vehicle 'Soyuz-FG' in Kazakhstan.

On October 11, 2018, in the Ulytau region of the Republic of Kazakhstan, the Soyuz-FG launch vehicle carrying a crewed MS-10 spacecraft failed, creating two areas where rocket propellants spilled and soil condition was monitored in 2018, 2019, 2022 and 2023. This article presents data on the content of pollutants, namely unsymmetrical dimethylhydrazine (UDMH), nitrosodimethylamine (NDMA) and total petroleum hydrocarbons (TPH), total N, organic carbon, exchangeable Ca and Mg, water-soluble NO-, NO-, HCO-, CO , SO , Cl, , Na, pH values, cation exchange capacity and electrical conductivity of the water extract in disturbed and background Aridisols (more than 200 samples in total). This data set contains information on interseasonal (autumn 2022 and spring 2023) differences in the content and vertical differentiation of some soil properties in Aridisols in Central Kazakhstan.

The Influence of Kerosene on Microbiomes of Diverse Soils.

One of the most important challenges for soil science is to determine the limits for the sustainable functioning of contaminated ecosystems. The response of soil microbiomes to kerosene pollution is still poorly understood. Here, we model the impact of kerosene leakage on the composition of the topsoil microbiome in pot and field experiments with different loads of added kerosene (loads up to 100 g/kg; retention time up to 360 days).

The Effect of Kerosene Pollution on the Cellulolytic Activity of Albic Retisols and Arenosols (Aridic): A Laboratory Experiment.

Unlabelled: The results of a laboratory experiment modeling the effect of kerosene contamination on the cellulolytic activity of microbiocenosis of the Albic Retisol (Kaluga oblast, Russia) and Arenosol (Kyzylorda oblast, Republic of Kazakhstan) humus horizons are described. Cellulolytic activity is assessed according to the rate of weight loss in linen cloth fragments during the incubation for 0-3, 3-7, and 7-13 months. The intensity of cellulolytic activity in the unpolluted Albic Retisol is higher as compared with the Arenosol, which is determined by low acidity and an elevated content of organic matter and nutrients.
