В работе представлены результаты исследования по обоснованию условий определения остаточных количеств неоникотиноидов (тиаметоксама и его метаболита клотианидина) в импортируемой пищевой продукции (бананы, цитрусовые, чай и кофе-бобы) с применением тандемной жидкостной масс-спектрометрии (ВЭЖХ-МС/МС) последнего поколения, источник ионизации — электростатическое распыление (режим положительной ионизации). Для идентификации использован режим мультиреакционного мониторинга с двумя переходами материнских ионов (для количественного расчёта и подтверждения по ионному соотношению).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Процедура пробоподготовки выполнена по технологии QuEChERS, включающей стадии экстракции, центрифугирования, очистки дисперсионной твердофазной экстракцией, повторного центрифугирования. Для образцов бананов, кофе и чая в качестве экстрагента использован ацетонитрил, подкислённый уксусной кислотой (1%). Пробы цитрусовых подвергали экстракции ацетонитрилом. Смесь сорбентов для твердофазной экстракции включала первичный-вторичный амин, окстадецилсилан и графитизированную сажу. В аналитические образцы кофе-бобов и чая, относящихся к продуктам с низким содержанием влаги, на стадии экстракции вносили воду в количестве в 2 и более раз превышающем массу пробы.</p></sec><sec><title>Результаты</title><p>Результаты. Нижний предел количественного определения тиаметоксама и его метаболита клотианидина в плодах бананов и цитрусовых составил 0,01 мг/кг, чае — 0,05 мг/кг и в кофе-бобах — 0,02 мг/кг, определён при соотношении сигнал/шум, равном 226 : 1 (тиаметоксам) и 16 : 1 (клотианидин). Полнота извлечения, установленная по результатам анализа модельных проб с внесением веществ в четырёх точках по диапазону определяемого содержания, составила 90–100%, среднее квадратичное отклонение повторяемости варьирует в диапазоне 5,7–8,4%.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. This paper presents the results of a study determination of neonicotinoids’ residues (thiamethoxam and its metabolite clothianidin) in imported food products (bananas, citrus fruits, tea, and coffee-beans) using tandem liquid-mass spectrometry (HPLC-MS/MS) of the last generation, ionization source, ESI (positive ionization mode). The mode of the MRM with two parent-ion transitions was used for the identification (for quantitative calculation and confirmation for an ionic ratio).</p></sec><sec><title>Material and methods</title><p>Material and methods. The sample preparation procedure was performed on the QuEChERS technology, including extraction, centrifugation, purification dispersion solid-phase extraction, repeated centrifugation. The acetonitrile acidified by acetic acid (1%) was used for extractions from samples of bananas, coffee, and tea, samples of a citrus subjected extractions with acetonitrile. At the extraction stage to the samples of coffee beans and tea, related to products with a low moisture content, water was added in an amount 2 or more times exceeding the mass of the sample.</p></sec><sec><title>Results</title><p>Results. The LLOQ of a thiamethoxam and its metabolite of a clothianidin in the fruits of bananas and citrus fruits — 0.01 ppm, tea — 0.05 ppm and coffee beans — 0.02 ppm, with a signal-to-noise ratio equal to 226:1 (thiamethoxam) and 16:1 (clothianidin). The recovery of the extraction, determined from the analysis of model samples with the fortification of substances at four levels on the range of the detected contents, accounтеd for 90-100%, the RSD of repeatability varied in the range of 5.7-8.4%.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>неоникотиноиды</kwd><kwd>высокоэффективная жидкостная хроматография</kwd><kwd>масс-спектрометрия</kwd><kwd>бананы</kwd><kwd>цитрусовые</kwd><kwd>чай</kwd><kwd>кофе-бобы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>neonicotinoids</kwd><kwd>HPLC-MS/MS</kwd><kwd>bananas</kwd><kwd>citrus fruits</kwd><kwd>tea</kwd><kwd>coffee beans</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">Справочник пестицидов и агрохимикатов, разрешенных к применению на территории Российской Федерации, Москва: Агрорус; 2015.</mixed-citation><mixed-citation xml:lang="en">Reference book of pesticides and agrochemicals permitted for use in the Russian Federation.
