Environmental health risk communication of nanotechnology: Policy issues and challenges for third world countries

With the rapid development of nanotechnology and its wide application in contemporary modern society. Recent argument amongst academia, publics and Government posed much questions on the how to educate the populace and acceptable communication strategies of nanomaterials, their interactions with ecological systems, and their public health risk assessment. The potential scientific prospects such as super-intelligent machines, direct connections between human brains or between brain and computer, and the reanimation of patients in cryonic suspension, Bio-genetic technologies, robotics, information technology and nanotechnology has posed new challenge in the 21^st century. Despite the burgeoning literature on the emerging nanotechnological impact, the question is what is in store for humanity? Little or no attention is paid to the environmental health dimension, risk perception and public health communication amongst vulnerable people in developing world where most potential users abound. The paper offers special insight into communication strategies and public perception that make general acceptance of nanotechnology   more complex and skeptical in the third world society. Also, environmental and public health safety issues concerning nanomaterials were examined by empirically administered structured questionnaire in west Africa and South Africa to elicit opinion on nanotechnology from people. Since risk assessment involved socio and ecological dimensions, a unique conceptualization of risk communication strategies is therefore articulated, tailored toward mainstreaming or elimination of negative nanotechnological effects and a multidimensional perspective for testing all materials on the nanoscale to evaluate the potential for harmful effects. This could serve as catalyst for social transformation and has implication for policy formulations, novel understanding of multidisciplinary approach to nanotoxicology by contribution knowledgeable insights no social component of Nanotechnology.
