TAILIEUCHUNG - Emerging challenges - Nanotechnology and the environment

The emerging scientific and policy challenges of nanotech- nology are examined from an environmental perspective. Na- notechnology will bring env- ironmental benefi ts but it is vital that we adopt appro- priate assessment and legis- lative processes to address the unique challenges presented by nanomaterials and their life cycles. | EMERGING CHALLENGES Nanotechnology and the environment Source Donna Sheppard Light up the World Foundation Introduction The environmental beneritsor _ nanotechnology The environmental risks of nanotechnology Looking ahead Nanotechnology and the environment Nanotechnology has enormous potential for social economic and environmental benefits frominnovative medical techniques to savings on materials and energy as well as advancesin detection and remediation of pollution. However with environmental impacts as yet largely unknown and public controls largely absent more systematic research and sector-specific policies are necessary. INTRODUCTION Nanotechnologyis a field of applied science concerned with the control of matter at dimensions of roughly 1 to 100 nanometres one nanometreis one-billionth of a metre Box 1 . The appeal of nanoparticlesis that they can be engineered to function in ways that naturally occurring materials do surface area per unit volume and enhanced chemical reactivity can be exploitedin novel applications. Reseacrhersin nanotechnology anticipate thatit will have profound effects onindustry and technology human health social and economic development and the environment public and privateinvestmentsin nanotechnology are significant and increasing because of its potential to transform sectors as diverse as medicine manufacturing energy water supply and transportation. Nanotechnologyis poised to become a major element in the global economy. In 2004 nanotech products accounted forless than 0 1 per cent of revenue from 2014 they are projected to account for 14 per cent totaling us 2 6 trillion afigure that will match theinformation technology and telecommunication industries combined bux Research 2004 Currently the private sector funds about half the research expendituresin nanotechnology. To date the majority of nanotechnology researchis being carried out by countries belonging to the Organization for Economic .
