Book excerpt: This book gathers the main international research findings on non-steroidal anti-inflammatory drugs (NSAIDs) as emerging contaminants in water. It focuses on the major routes of exposure, and the destinations and life cycles of NSAIDs in water, as well as the manifestations of toxicity in different organisms. It also reviews the methods used in the detection, analysis and quantification of NSAIDs in water as well as the biological and chemical methods of removing them. Lastly, the book offers an overview of the legal frameworks in place and provides conclusions and recommendations for the future. Given its scope, the book is an indispensable resource for scientists in academia and industry, as well as for decision-makers involved in contamination assessment and environmental analysis and NGOs interested in the problem of water contamination by NSAIDs.
