Временные границы анализируемого периода – 71 год (с 1952 по 2023 г.).</p><p>В обзоре приведены методики определения бензола, этилбензола и акрилонитрила в водных средах (вода централизованного и нецентрализованного водоснабжения, водоисточников хозяйственно-бытового и рекреационного водопользования, морская вода в местах водопользования населения, вода плавательных бассейнов и аквапарков, вода поверхностных водоисточников, используемых для централизованного водоснабжения населения, хозяйственно-бытового водопользования и водоснабжения пищевых предприятий), основанные на использовании физико-химических методов анализа – спектрофотометрии, газовой хроматографии (ГХ), высокоэффективной жидкостной хроматографии с различными типами детекторов (ВЭЖХ), хромато-масс-спектрометрии (ГХ-МС).</p><sec><title>Заключение</title><p>Заключение. Анализ методических документов показал несовершенство российской методической базы, охватывающей контроль бензола, этилбензола и акрилонитрила в водных средах. В связи с изменением нормативных показателей СанПиН 1.2.3685–21 в питьевой воде централизованного и нецентрализованного водоснабжения чувствительность ранее разработанных методик стала недостаточной, что требует разработки прецизионных аналитических методик хромато-масс-спектрометрического анализа токсичных бензола, этилбензола и акрилонитрила в водных средах с характеристиками, соответствующими международным стандартам.</p></sec><sec><title>Участие авторов</title><p>Участие авторов: Нурисламова Т.В. – концепция, научное консультирование, актуальность, заключение; Зайцева Н.В. – концепция, научное консультирование, актуальность; Попова Н.А. – материалы и методы, результаты; Мальцева О.А. – актуальность, результаты, обсуждение, заключение.

The analyzed period was 71 year (between 1952 and 2023).</p><p>The review dwells on methodologies for identifying benzene, ethylbenzene, and acrylonitrile in water media (tap water, water from non-centralized water supply, water objects used for household needs and recreation, sea water in places used by people, water in swimming pools and aqua parks, water in surface sources used for centralized drinking water supply, household needs and at food manufacturing enterprises). The outlined methodologies rely on using physical and chemical analytical methods including spectrophotometry, gas chromatography (GC), high performance liquid chromatography (HPLC) with different detectors, gas chromatography – mass spectrometry (GC-MS).</p><sec><title>Conclusion</title><p>Conclusion. Analysis of available methodical documents has revealed the Russian methodological base on control of toxic benzene, ethylbenzene and acrylonitrile in water to be far from the perfect. Given the introduced changes in regulatory indicators in the SanPiN 1.2.3685–21 in drinking water from centralized and non-centralized water supply systems, sensitivity of previously developed methodologies has become insufficient. This requires developing new precise analytical methodologies of gas chromatography – mass spectrometry to identify toxic benzene, ethylbenzene, and acrylonitrile in water media with characteristics conforming to international standards.</p></sec><sec><title>Contributions</title><p>Contributions: Nurislamova Т.V. – study concept, scientific advice on relevance; conclusions; Zaitseva N.V. – study concept, scientific advice on relevance; Popova N.А. – materials and methods, results; Maltseva О.А. – relevance, results, discussion, conclusions.
