Многие из этих продуктов (включая и сам CS) являются весьма реакционноспособными веществами, вследствие чего состав аэрозоля значительно отличается от набора продуктов, которые можно обнаружить впоследствии в объектах окружающей среды.</p><p>Цель работы – обнаружение и идентификация производных CS в образцах грунта и в материале газовых гранат, доставленных из зоны проведения специальной военной операции, для оценки их относительного содержания и выбора перспективных маркеров факта применения CS.</p><sec><title>Методы исследования</title><p>Методы исследования. Обнаружение и структурную идентификацию продуктов деградации CS выполняли методами газовой и жидкостной хромато-масс-спектрометрии низкого и высокого разрешения.</p></sec><sec><title>Результаты исследования</title><p>Результаты исследования. Обнаружены более 30 соединений, являющихся продуктами окисления, восстановления, термолитической деструкции и димеризации CS и его производных. Методом жидкостной хромато-масс-спектрометрии, ранее не использовавшегося для подобных работ, предположительно идентифицировали пять соединений, сведения о которых в отношении газовых гранат отсутствуют в доступных нам источниках.</p></sec><sec><title>Вывод</title><p>Вывод. В случае анализа объектов методом газовой хромато-масс-спектрометрии наиболее удобным маркером применения CS является 2-хлорбензилмалонилдинитрил, в то время как содержание самого CS может быть незначительным. Для варианта анализа методом жидкостной хромато-масс-спектрометрии предпочтителен поиск продуктов циклизации CS хинолиновой природы (положительный режим ионизации), а для отрицательного режима – продуктов димеризации и восстановления CS.</p></sec></abstract><trans-abstract xml:lang="en"><p>The formation of a CS aerosol during the combustion of a pyrotechnic mixture in gas grenades is accompanied by the formation of numerous thermolytic degradation products. Many of these products (including CS itself) are highly reactive substances, as a result of which the composition of the aerosol differs significantly from the set of products that can be subsequently detected in environmental objects.</p><p>The aim of the work is to detect and identify CS derivatives in soil samples and in the material of gas grenades delivered from the zone of a special military operation to assess their relative content and select promising markers of the fact of CS use.</p><sec><title>Research methods</title><p>Research methods. Detection and structural identification of CS degradation products were performed using gas and liquid chromatography-mass spectrometry (lowand high-resolution).</p></sec><sec><title>The results of the study</title><p>The results of the study. More than 30 compounds have been found that are products of oxidation, reduction, thermochemical degradation and dimerization of CS and its derivatives. The method of liquid chromatography-mass spectrometry, which was not previously used for such work, presumably identified five compounds, information about which in relation to gas grenades is not available in the sources available to us.</p></sec><sec><title>Conclusion</title><p>Conclusion. In the case of object analysis by gas chromatography-mass spectrometry, the most convenient marker of CS exposure is 2-chlorobenzylmalonyl nitrile, while the content of CS itself may be insignificant. For the variant of analysis by liquid chromatography-mass spectrometry, it is preferable to search for products of cyclization of CS of quinoline origin (positive ionization mode), and for the negative mode products of dimerization and reduction of CS.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>CS</kwd><kwd>газовая хромато-масс-спектрометрия</kwd><kwd>деградация</kwd><kwd>жидкостная хромато-массспектрометрия</kwd><kwd>маркеры воздействия</kwd><kwd>специальная военная операция</kwd><kwd>термолиз</kwd><kwd>точные массы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>CS</kwd><kwd>accurate masses</kwd><kwd>degradation</kwd><kwd>exposure markers</kwd><kwd>gas chromatography-mass spectrometry</kwd><kwd>liquid chromatography-mass spectrometry</kwd><kwd>special military operation</kwd><kwd>thermolysis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Федеральное государственное бюджетное учреждение «27 Научный центр имени академика Н.Д.
