Unique genetic resources of plant biodiversity are concentrated in Kazakhstan. Economically important species make a significant contribution to the structure of the Earth in comparison with taxa with insignificant or unknown economic use, many economically valuable species of Kazakhstan are of global importance.The purpose of this work is to identify economically valuable species of Northern Kyzylkum within the Republic of Kazakhstan. Objects and methods of research: To collect and identify species, classical botanical, route-reconnaissance; ecological-systematic; ecological-geographical methods were used. The main groups of useful plants of economically valuable flora species of Northern Kyzylkum were identified: woody, food, medicinal, fodder, decorative, technical species.During the research, it was revealed that 310 economically valuable species belonging to 62 families and 196 genera are found in Northern Kyzylkum within the Republic of Kazakhstan. According to the results of the classification, the dominant families are determined: Poaceae Barnhart has 34 genera, 58 species; Asteraceae Dumortier -24 genera, 46 species; Chenopodiaceae Vent. -19 genera, 30 species; Fabaceae Juss. -11 genera, 23 species. The study analyzed 200 types of medicinal, 100 types of fodder, 22 types of decorative, 11 types of sand fixers, 9 types used for fuel according to significant economic valuable characteristics. According to the classification of economically valuable species by life forms, tree forms were identified in 6 species: Salix alba L., Populus diversifolia Schrenk, P. pruinosa Schrenk, Acer negundo L., Elaeagnus angustifolia L., Haloxylon persicum Bunge ex Boiss., 44 shrubs and semi-shrubs, 155 perennials, 105 biennial and annual plants.

“…In 2018–2020, 127 of the 329 orbital rocket launches were conducted using highly toxic hypergolic fuel – unsymmetrical dimethylhydrazine (UDMH) [1] mixed with NO 2 as an oxidant. After launch, burned‐out rocket stages fall at the distance ≤1500 km from a launchpad [2], such as Baikonur (Kazakhstan), resulting in contamination of the environment with ≤4 tons of unburned fuel [3–5] in the case of a successful launch and ≤600 tons in the case of an accident [6]. Under the effect of NO 2 , oxygen, sunlight, elevated temperatures, biota, soil, and water constituents [7–9], UDMH transforms into a number of potentially dangerous substances – amines, nitrosoamines, triazoles, pyrazoles, and amides [10,11].…”

Quantification of unsymmetrical dimethylhydrazine transformation products in ambient air is important for assessing the environmental impact of heavy rocket launches. There are very little data of such analyses, which is mainly caused by the low number of analytes covered by the available analytical methods and their complexity. A simple and cost‐efficient method for accurate simultaneous determination of seven unsymmetrical dimethylhydrazine transformation products in air using solid‐phase microextraction followed by gas chromatography‐mass spectrometry was developed. The method was optimized for air sampling and solid‐phase microextraction from 20‐mL vials, which allows full automation of analysis. The extraction for 5 min by Carboxen/polydimethylsiloxane fiber from amber vials and desorption for 3 min provided the greatest analytes' responses, lowest relative standard deviations, linear calibration (R2 ≥ 0.99), and limits of detection from 0.12 to 0.5 μg/m3. Samples with concentrations 500 μg/m3 can be stored at 21 ± 1°C without substantial losses (1–11%) for up to 24 h, while air samples with concentrations 10 and 50 μg/m3 stored for up to 24 h can be used for accurate quantification of only two and four out of seven analytes, respectively. The developed method was successfully tested for the analysis of air above real soil samples contaminated with unsymmetrical dimethylhydrazine rocket fuel.
