   <abstract xml:lang="ru">
    <p>Фенолы относятся к приоритетным загрязнителям окружающей природной среды и попадают в водные источники через очистные сооружения промышленных предприятий. Они представляют определенную угрозу организму человека, так как многие из них характеризуются высокой токсичностью и относятся к первому классу опасности. Особо высокую токсичность проявляют хлорорганические производные фенола, которые в условиях дезинфекции воды хлорсодержащими препаратами могут образовывать полихлорированные дибензо-n-диоксины, которые относятся к суперэкотоксикантам и оказывают негативное влияние на генетический код организма человека. В результате проведенных исследований поверхностные воды бассейна реки Волги Куйбышевского водохранилища были проанализированы на содержание фенола и его производных методом газожидкостной хроматографии. При анализе фенолов в водной среде установлено превышение норм предельно-допустимых концентраций для орто-, мета-, пара- хлорфенолов, которые характеризуются высокой токсичностью для организма человека и живой природы. Установлена динамика сезонных изменений концентрации фенола и его производных в поверхностных водах реки Волги, которые связываются с интенсификацией окислительно-восстановительных процессов&#13;
в летний период времени, протекающих под влиянием температурных факторов с участием растворенного кислорода.</p>

    <p>Phenols are priority pollutants of the natural environment and enter water sources through wastewater treatment plants of industrial enterprises. They pose a certain threat to the human body, since many of them are highly toxic and belong to the first class of danger. Organochlorine derivatives of phenol exhibit particularly high toxicity; under conditions of water disinfection with chlorine-containing preparations, they can form polychlorinated dibenzo-n-dioxins, which are classified as super-ecotoxicants and have a negative effect on the genetic code of the human body. As a result of the studies, the surface waters of the Volga river basin of the Kuibyshev reservoir in the water area of the city of Kazan were analyzed for the content of phenol and its derivatives using gas-liquid chromatography. When analyzing phenols in the aquatic environment, it was established that the maximum permissible concentrations norms for ortho-, meta-, para- chlorophenols, which are characterized by high toxicity to the human body and wildlife, were exceeded. The dynamics of seasonal changes in the concentration of phenol and its derivatives in the surface waters of the Volga river has been established, which are associated with the intensification of redox processes in the summer, occurring under the influence of temperature factors involving dissolved oxygen.</p>
