This book focuses not only the impact of nanotechnology and the discipline of nanotoxicity, but also explains each of these disciplines through the eyes of management requirements and via risk scenarios - providing an overview of regulation, managing risk and exposure. Contributors thoroughly explain EHS issues, financial implications, foreseeable risks (i.e. exposure, dose, hazards of nanomaterials), occupational hygiene, and consumer protection. The second edition has been expanded by 50%, with key new chapters covering eco-toxicity, nanomedicine, informatics and future threats. New case studies have also been added, including a chapter on the impact of nanosilver on the environment. Practical guidance on risk management and mitigation across different legislatory frameworks worldwide. Reviews toxicological studies and industrial initiatives, supported by numerous case studies. A major revision: 50% new material, including extensive material on nanohealth and medicine, and new case studies
