Плоды цитрусовых культур благодаря их полезным свойствам и витаминной наполненности занимают существенное место в фактическом питании населения, в том числе детей и подростков, но в силу природно-климатических условий не могут возделываться в нашей стране и относятся к категории импортируемой продукции, что обосновывает важность контроля их безопасности.</p><p>Цель работы – разработка метода для одновременного многокомпонентного определения остаточных количеств пестицидов и их метаболитов в плодах цитрусовых культур.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Для идентификации и количественного определения при совместном присутствии действующих веществ пестицидов, относящихся к различным химическим классам (аминопиримидины, имидазолы, карбаматы, стробилурины, триазолы, ФОС и др.), использованы методы высокоэффективной жидкостной хроматографии с тройным квадрупольным масс-детектором (ВЭЖХ-МС/МС) в режиме мониторинга множественных реакций (MRM) и газожидкостной хроматографии с масс-селективным детектором (ГЖХ-МС) в режиме мониторинга выбранных ионов (SIM). Пробоподготовку выполняли согласно методике QuEChERS, основанной на извлечении веществ из гомогенизированного образца органическим растворителем в присутствии солей, содержащих цитратный буфер, с последующей очисткой аликвоты экстракта дисперсионной твердофазной экстракцией.</p></sec><sec><title>Результаты</title><p>Результаты. Созданный мультиметод определения остаточных количеств широкого спектра соединений (50 наименований действующих веществ пестицидов и их токсичных метаболитов) в цитрусовых использован для исследования плодов цитрусовых культур (лимоны, грейпфруты, апельсины, мандарины), импортированных из Египта, Турции и Абхазии, приобретённых на потребительском рынке. Идентифицированные уровни действующих веществ пестицидов не превышали установленных величин МДУ.</p></sec><sec><title>Заключение</title><p>Заключение. Современное развитие аналитической химии пестицидов, использование тандема газовой и жидкостной хроматографии с масс-спектрометрическим детектированием позволили реализовать групповой метод количественного измерения действующих веществ пестицидов и их токсичных метаболитов в плодах цитрусовых культур, направленный на выявление содержания их остаточных количеств в исследуемой продукции.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Thanks to possessing beneficial properties and vitamin content, citrus fruits occupy a prominent place in the ubiquitous nutrition of all ages due to various crops. On the other hand, due to climatic conditions, they cannot be cultivated in our country and are classified as imported products, which justifies the importance of controlling their safety.</p></sec><sec><title>Purpose of the work</title><p>Purpose of the work. The creation of a multicomponent method for determining the residual amounts of pesticides and their metabolites in citrus fruits.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. HPLC with triple quadrupole mass detector in multiple reaction monitoring (MRM) mode and capillary gas-liquid chromatography with mass selective detector (GC-MC) in selected ion monitoring mode (SIM) together were used to perform the identification and quantitative determination of the active substances of pesticides of various classes (amino pyrimidines, imidazoles, carbamates, strobilurins, triazoles, organophosphorus compounds, etc.) As a sample preparation method, there was used the QuEChERS technology, based on the extraction of pesticides with an organic solvent from a homogenized sample in the presence of salts containing citrate buffer and the purification of the extracts by dispersive solid-phase extraction.</p></sec><sec><title>Results</title><p>Results. To control the safety of citrus fruits (lemons, grapefruits, oranges, tangerines) imported from Egypt, Turkey and Abkhazia, purchased on the food market, a multi-method was used for determining the residual amounts of a wide range of pesticide compounds (50 names of active ingredients of pesticides and their toxic metabolites) in citrus fruits. The identified levels of active pesticide ingredients did not exceed the established MRLs.</p></sec><sec><title>Conclusion</title><p>Conclusion. The modern development of the analytical chemistry of pesticides, the use of a tandem of gas and liquid chromatography with mass spectrometric detection made it possible to implement a group method for the quantitative determination of the active substances of pesticides and their toxic metabolites in citrus fruits. Modern development makes it possible to detect the contamination of their residual amounts in the processed products.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>пестициды</kwd><kwd>QuEChERS</kwd><kwd>плоды цитрусовых</kwd><kwd>аналитический контроль остаточных количеств</kwd><kwd>ГЖХ-МС</kwd><kwd>ВЭЖХ-МС/МС</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pesticides</kwd><kwd>QuEChERS</kwd><kwd>citrus</kwd><kwd>analytical control of residues</kwd><kwd>GC-MS</kwd><kwd>HPLC-MS/MS</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Климова Е.В.
