M. is a unique and in-depth study dedicated to topical issues of assessing the quality of aquatic ecosystems and their inhabitants. Published under the auspices of P. Yaroslavl State University G. Demidov, this work is not only a scientific work, but also a practical guide for specialists in the field of ecology, biology and toxicology. The book examines key aspects of biotesting, which plays an important role in assessing the effects of various pollutants on aquatic organisms. The authors describe in detail the methods and approaches used to determine toxicity, as well as their importance for the protection of the environment. The reader will be able to learn about current research methods, such as cell- and organism-level testing, and how the results of these tests can be used to develop strategies to protect water resources. This book will be of interest not only to professional ecologists and toxicologists, but also to students studying related disciplines, as well as to anyone interested in environmental protection and sustainable development. It will be a useful resource for those who want to better understand how water pollution affects biodiversity and ecosystem health. The age category of readers is not limited, since the material is available and understandable, which allows you to attract both novice researchers and experienced specialists. The topics raised in the book cover a wide range of issues related to environmental safety, sustainable development, and water conservation. The authors emphasize the importance of biotesting as a tool for assessing the impact of anthropogenic factors on aquatic ecosystems, which makes the book especially relevant in the light of modern environmental challenges. With global climate change and increasing water pollution, understanding toxicological processes is becoming not just important, but vital for the conservation of ecosystems. The style of the authors is characterized by scientific rigor and at the same time the availability of presentation, which allows the reader to easily assimilate complex concepts and ideas.
