Читать книгу Analytical Methods for Environmental Contaminants of Emerging Concern - Группа авторов - Страница 10

The occurrence of organic compounds of emerging concern (CECs) in the environment has given rise to growing unease. Although most CECs have been present in the environment for years, some of them have only recently been identified. Thus, some of these compounds remain unregulated and their toxicity and risk unstudied. They occur in different environmental compartments at trace levels (low ppb or ppt). Moreover, CECs belong to different families with several origins and have a broad range of physical-chemical properties. To respond to this situation, sensitive and selective analytical methods have been developed to determine different types of CECs in a broad range of environmental samples. Most of these analytical methods comprise sample preparation followed by chromatographic separation coupled to mass spectrometry. The specific requirements at each step of the analytical method are linked to the properties of the contaminants and sample matrix.

The aim of this book was to compile the analytical methods available to determine CECs in environmental samples. It is organized by families of CECs, with each chapter presenting complete information for each family. The chapters are dedicated to the following families of CECs: pesticides (Chapter 1); pharmaceuticals (Chapter 2); personal care products (Chapter 3); novel psychoactive substances (Chapter 4); artificial sweeteners (Chapter 5); perfluorinated substances (Chapter 6); high production volume chemicals (Chapter 7); musk fragrances (Chapter 8); disinfection byproducts (Chapter 9); and microplastics (Chapter 10). The relevant environmental samples are covered in each chapter (i.e., family of CECs): different types of water (drinking, tap, surface, and sewage), solids (sediment, soil, sludge, dust, as well as biota), and atmospheric samples (air and particulate matter). With a few exceptions, the content of each chapter is organized into the same sections – an overview, sample preparation and collection, determination, and future directions. In each chapter, different analytical methods are proposed through examples of cutting-edge research studies that are summarized in the form of tables to provide an overview of the state of the art; however, the common methods currently employed are also described so that the reader can identify the methods typically used. Thus, this book provides a detailed description of the different approaches for determining each group of CECs in environmental samples with distinctive, critical information about the state of the art for their determination in the environment. The editors truly hope that this book will serve to help researchers, industrial experts, students, decision-makers, and interested members of society learn about the approaches available to monitor each family of CECs, covering most of the CECs occurring in the environment.

We would like to acknowledge the authors for their invaluable contributions. All of the authors of this book are experts and skilled professionals in environmental trace analysis and, in particular, in each of the families of CECs addressed in each specific chapter. Without their effort and dedication, this book would have not been possible. We also sincerely thank our readers for their interest in this book. Thanks for reading and we hope you enjoy it!Núria Fontanals and Rosa Maria Marcé
