ABSTRACT
The widespread use of nanomaterials (NMs) in biomedical and environmental applications, consumer goods, food industry and drug delivery systems has raised concerns about their potential risks to human health and ecotoxicological effects. Inadequate understanding of the health risks and ecological impacts of NMs may create new societal challenges. Therefore, a comprehensive understanding of the interactions and effects of NMs in the environment is essential for developing and implementing appropriate safety measures and environmental guidelines regarding their production and use. This book chapter provides a comprehensive review of major aspects of NMs in the environment, elaborating on the sources, fate, transport, risk assessment and ecotoxicity. It also examines the current state of NM research to identify the knowledge gaps and justify the need for additional research.
