The book "Sampling and sample preparation methods" by Yu. A. Karpova is an indispensable work for anyone interested in modern methods of environmental analysis and research, as well as for specialists in the field of ecology, chemistry and biology. In this publication, the author examines in detail the key aspects of sampling and sample preparation, which makes it relevant not only for students and graduate students, but also for professionals working in laboratories and scientific institutions. Yu. A. Karpov, known for his in-depth research in ecology and analytical chemistry, offers the reader a unique look at the methods that are used to produce quality samples. The book examines both traditional and modern approaches, allowing readers to gain a complete understanding of the sampling process. The author focuses on the importance of choosing the right methods, as this directly affects the results of research and their interpretation. The book will be of particular interest to those involved in environmental monitoring, pollutant analysis, as well as those working in the field of quality control of products and materials. Students studying ecology, chemical technology or biology will find in it useful tips and practical recommendations that will help them in their studies and future professional activities. Professionals working in laboratories will be able to use the knowledge gained to improve their techniques and improve the accuracy of analyzes. One of the key topics raised in the book is the importance of trial preparation. Karpov explains in detail how improper sampling methods can lead to data distortion, which in turn can affect environmental and human health decision-making. He shares examples from practice, which makes the material more visual and understandable. Readers will be able to see how theoretical knowledge is applied in practice, and what consequences may arise from a careless approach to sampling. Style Y. A. Karpova is distinguished by clarity and accessibility, which allows even complex scientific concepts to be explained in simple and understandable language. His previous works, such as Environmental Monitoring: Theories and Practices and Analytical Chemistry in Ecology, have also been recognized for their informative and practical focus. In "Sampling and sampling methods" the author continues this tradition, offering readers not only theoretical knowledge, but also practical advice that can be applied in real life. The book will be an excellent addition to the library of any specialist in the field of ecology and analytical chemistry. It will help to understand the intricacies of sampling, which is especially important in the modern world, where environmental issues and environmental protection are becoming increasingly important. Readers interested in the topics of sustainable development, ecology and environmental protection will find in it a lot of useful and inspiring. Thus, “Sampling and sample preparation methods” is not just a textbook, but a whole world of knowledge that will open doors to the world of exact scientific research and help each reader to become more competent in his field. Do not miss the opportunity to immerse yourself in this fascinating and important topic that concerns each of us.
