В связи с ужесточением гигиенического показателя допустимой концентрации в почве для гербицида на основе производного феноксиуксусной кислоты (МЦПА) с 0,04 до 0,003 мг/кг возникла необходимость оптимизировать аналитические подходы к его определению.</p><p>Цель исследования – разработать современный метод для определения МЦПА в почве с использованием высокоэффективной жидкостной хроматографии с масс-спектрометрическим детектированием (ВЭЖХ-МС/МС), упростив предшествующую методику изменением подготовки проб и исключением процесса дериватизации вещества перед анализом.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Определение проводили методом тандемной жидкостной масс-спектрометрии с тройным квадрупольным масс-детектором в режиме мониторинга множественных реакций, используя в качестве источника ионов электро-спрей ионизацию. Вещество из проб почвы извлекали раствором гидроксида натрия с последующим подкислением соляной кислотой до рН 3. Дальнейшее очищение экстракта проводили на патроне для твердофазной экстракции на основе сополимера дивинилбензола и N-винилпирролидона.</p></sec><sec><title>Результаты</title><p>Результаты.

Удалось установить уровень нижнего предела количественного определения МЦПА на уровне 0,001 мг/кг (при установленном значении ПДК – 0,003 мг/кг). Быстрый и чувствительный метод ВЭЖХ-МС/МС позволил значительно сократить время пробоподготовки в сравнении с методами газожидкостной хроматографии (ГЖХ), исключив стадию дериватизации вещества в метиловый эфир.</p></sec><sec><title>Ограничения исследования</title><p>Ограничения исследования.

Due to the tightening of the hygienic indicator of permissible concentration in soil for herbicide based on phenoxyacetic acid derivative (MCPA) from 0.04 mg/kg to 0.003 mg/kg, it became necessary to optimize analytical approaches to its determination.</p><p>The aim of the study is to develop a modern method for determining MCPA in soil using high-performance liquid chromatography with mass spectrometric detection (HPLC-MS/MS), simplifying the previous technique by changing sample preparation and excluding the process of substance derivatization before analysis.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Determination was conducted by tandem liquid mass spectrometry with triple quadrupole mass detector (HPLC-MS/MS) in multiple reaction monitoring mode, using electrospray ionization as an ion source. The substance was extracted from soil samples with sodium hydroxide solution followed by acidification with hydrochloric acid to pH 3. Further purification of the extract was carried out on a solid-phase extraction cartridge based on a copolymer of divinylbenzene and N-vinylpyrrolidone.</p></sec><sec><title>Results</title><p>Results. The method was validated on standard soil samples of three different soil types by means of additions “applied-found”. It was possible to set the level of the lower limit of MCPA quantification at 0.001 mg/kg (with a set MPC value of 0.003 mg/kg).</p></sec><sec><title>Limitations</title><p>Limitations. The development was carried out using standard soil samples of three types available to the laboratory.</p></sec><sec><title>Conclusion</title><p>Conclusion. The developed method included in the Register of certified methods. The approach proposed in the method allows analyzing a larger number of samples in less time and can be used in monitoring studies of MCPA residues in soil. Fast and sensitive HPLC-MS/MS method allowed to significantly reduce the sample preparation time in comparison with other gas-liquid chromatography methods, excluding the stage of derivatization of the substance into methyl ether.</p><p>Compliance with ethical standards. The study does not require the submission of the conclusion of the Biomedical Ethics Committee or other documents is required.</p></sec><sec><title>Author contribution</title><p>Author contribution: Grechina M.S. – the concept and design of the study, the collection and processing of the material, statistical analysis, writing a text, editing; Belitskaya V.V. – the collection and processing of the material, statistical analysis, writing a text, editing.
