Фураны входят в перечень основных экополютантов, составляющих ксенобиотический профиль. Высокая канцерогенность и мутагенность фуранов даже при низких концентрациях в организме человека, порядка 10–12–10–15 г/кг, могут создавать реальную угрозу здоровью настоящего и будущих поколений.Цель исследования: разработка и валидация авторской методики количественного определения потенциально опасных фурана и метилфурана в крови человека для обеспечения контроля за содержанием экзогенных соединений в биологических средах, для выполнения работ по оценке риска здоровью населения при воздействии химических веществ.Материалы и методы. Разработка методики определения фурана и метилфурана в крови человека основана на принципах: установление хромато-масс-спектрометрических условий анализа; экспериментальная отработка эффективных способов подготовки образца биосреды (кровь) к хромато-масс-спектрометрическому анализу; экспериментальное доказательство пригодности разработанной методики для решения задач по количественному определению фурана и метилфурана в крови.Результаты. Разработанная методика базируется на жидко-жидкостной экстракции органическим растворителем с целью извлечения и концентрирования аналитов в щелочной среде в течение 5 минут до установления межфазного равновесия и дальнейшем анализе экстракта методом капиллярной газовой хроматографии. Достигнута высокая степень извлечения фурана и метилфурана из образцов крови 98 и 98,5 %. Для идентификации фуранов в биосреде применяли масс-спектрометрическое детектирование с регистрацией спектра масс-ионов.Выводы. На основании выполненных исследований разработана и валидирована в условиях лаборатории высокочувствительная и специфичная методика газохроматографического определения фурана и метилфурана в крови с масс-спектрометрическим детектированием. Диапазон измеряемых концентраций для фурана и метилфурана составил от 0,0019 до 0,09 мг/дм3. В процессе валидации методики установлены пределы обнаружения (LOD) изучаемых соединений в крови, которые составили для фурана до 0,00011 мкг/см3 и до 0,000021 мкг/см3 для метилфурана.</p></abstract><trans-abstract xml:lang="en"><p>Background: Furans are global ecotoxicants making up the xenobiotic profile. High carcinogenicity and mutagenicity of these chemicals for humans even at concentrations as low as 10–12–10–15 g/kg, can pose health risks for the present and future generations.Our objective was to develop and validate the authors’ method of measuring potentially dangerous furan and methylfuran in human blood to ensure control over the levels of exogenous compounds in biological fluids for further assessment of related human health risks.Materials and methods: Development of the technique of measuring in human blood levels of furan and methylfuran was based on the following principles: establishment of gas chromatography-mass spectrometry (GC-MS) analytical conditions; experimental search for effective methods of blood sample preparation for the GC-MS analysis, and validation of the developed procedure.Results: The method includes liquid-liquid extraction with a polar organic solvent in an alkaline medium during 5 minutes until the inter-phase equilibrium is reached and further capillary gas chromatography. It ensures a high degree of recovery of furan and methylfuran from blood samples equaling 98 % and 98.5 %, respectively. Mass spectrometry detection with registering the mass spectrum of ions was used for identifying furans in the biological fluid.Conclusions: We have developed and validated a highly sensitive and specific method for GC-MS measurement of furan and methylfuran in human blood within the range of 0.0019 to 0.09 mg/dm3. The limits of detection of the chemicals were established within method validation, which appeared to be up to 0.00011 μg/cm3 for furan and up to 0.000021 μg/cm3 for methylfuran.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>экстракция</kwd><kwd>фуран и метилфуран</kwd><kwd>газовая капиллярная хроматография</kwd><kwd>масс-спектрометрическое детектирование</kwd><kwd>LOD</kwd><kwd>LOQ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>extraction</kwd><kwd>furan</kwd><kwd>methylfuran</kwd><kwd>capillary gas chromatography</kwd><kwd>mass spectrometric detection</kwd><kwd>LOD</kwd><kwd>LOQ</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">Kudryavtseva AD, Shelepchikov AA, Brodsky ES.
