Chương này tập hợp nhiều người trong số các khái niệm trung tâm phát triển trong trước chương để đi đến các chủ đề cốt lõi của cuốn sách này - thông qua cuộc sống chu kỳ suy nghĩ và đánh giá rủi ro để quản lý các mối nguy hiểm của vật liệu nano và công nghệ nano. Xây dựng trên sự hiểu biết cơ bản về rủi ro đánh giá được đưa ra trong Chương 2, nó mô tả các khái niệm quản lý thích ứng và kiểm tra mức độ phân tích, và giải thích NANO LCRA, các đề xuất thích nghi khuôn. | 6__ NANO LCRA An Adaptive ScreeningLevel Life Cycle Risk Assessment Framework for Nanotechnology Jo Anne Shatkin CONTENTS Adaptive Management for Nanomaterials Using Risk Screening-Level Risk Assessment and Adaptive NANO LCRA An Adaptive Screening-Level Life Cycle Risk Assessment Framework for The Ten-Step NANO LCRA Examples using the NANO LCRA Summary . 111 References . 111 Good risk assessment is essential for good risk management. NSET 2007 This chapter brings together many of the central concepts developed in the preceding chapters to arrive at the core theme of this book adopting life cycle thinking and risk assessment for managing the hazards of nanomaterials and nanotechnology. Building on the basic understanding of risk assessment given in Chapter 2 it describes the concepts of adaptive management and screening-level analysis and explains NANO LCRA the proposed adaptive screening-level risk assessment framework that incorporates life cycle thinking. NANO LCRA is based on adaptive management and involves revisiting the framework and reevaluating prior decisions with new information. The screening-level or qualitative assessment process is targeted to today s decision making that is in the current state of uncertainty about the environmental and biological behavior of nanomaterials. As with any 97 2008 by Taylor Francis Group LLC 98 Nanotechnology Health and Environmental Risks emerging issue sound management is imperative but there is too much uncertainty to devise science-based regulation. This framework provides a sound scientific basis for sustainable nanotechnology development. Following the discussions in Chapters 4 and 5 of the state of the science it is clear that the scientific understanding of nanomaterial behavior in terms of health and environment is in an early stage. It is not infancy because much of what has .
