“…The effect of hydrocarbon pollution on CA has been most frequently studied in the soils contaminated with oil, mazut, gasoline, and motor oils [ 21 , 23 , 24 ] and less frequently, with kerosene [ 10 ]. A high migration ability of kerosene and its toxicity for biota determined the need to assess the allowable load of hydrocarbons of this type on the components of ecosystems, especially, the areas adjacent to airfields and spaceports [ 19 , 25 , 27 , 37 , 46 , 47 ].…”

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. The soil pollution with kerosene to 10 g/kg causes a reversible change in cellulolytic activity of both Albic Retisol and Arenosol (Aridic). A high load of kerosene (≥25 g/kg) inhibits cellulolytic activity in both soils over 13 months of observation.

“…The use of highly toxic rocket fuel based on 1,1-dimethylhydrazine (unsymmetrical dimethylhydrazine, UDMH) in many types of Russian, Indian, EU, and Chinese launch vehicles inevitably gives rise to a risk of environmental pollution. It can be associated with an ingress of rocket fuel into soils and water bodies in fall sites of spent rocket stages, emergency situations, as well as the disposal of UDMH containing wastewater generated at launch sites during storage, transportation of fuel, and refueling the carrier rockets [ 1 , 2 ]. The situation is complicated by the high reactivity of UDMH causing the rapid formation of a large number (up to several hundreds) of toxic nitrogen-containing products of its oxidative transformations upon contact with atmospheric air or reagents used in the detoxification of waters and soils [ 3 , 4 , 5 ].…”

Gas Chromatography–Mass Spectrometry Quantification of 1,1-Dimethylhydrazine Transformation Products in Aqueous Solutions: Accelerated Water Sample Preparation

The use of highly toxic rocket fuel based on 1,1-dimethylhydrazine (UDMH) in many types of carrier rockets poses a threat to environment and human health associated with an ingress of UDMH into wastewater and natural reservoirs and its transformation with the formation of numerous toxic nitrogen-containing products. Their GC-MS quantification in aqueous samples requires matrix change and is challenging due to high polarity of analytes. To overcome this problem, accelerated water sample preparation (AWASP) based on the complete removal of water with anhydrous sodium sulfate and transferring analytes into dichloromethane was used. Twenty-nine UDMH transformation products including both the acyclic and heterocyclic compounds of various classes were chosen as target analytes. AWASP ensured attaining near quantitative extraction of 23 compounds with sample preparation procedure duration of no more than 5 min. Combination of AWASP with gas chromatography–mass spectrometry and using pyridine-d5 as an internal standard allowed for developing the rapid, simple, and low-cost method for simultaneous quantification of UDMH transformation products with detection limits of 1–5 μg L–1 and linear concentration range covering 4 orders of magnitude. The method has been validated and successfully tested in the analysis of aqueous solutions of rocket fuel subjected to oxidation with atmospheric oxygen, as well as pyrolytic gasification in supercritical water modelling wastewater from carrier rockets launch sites.
