Interactive survey of consumer awareness of nanotechnologies and nanoparticles in consumer products in South Korea.

Abstract

BackgroundThe purpose of our study was to understand consumers’ risk awareness and need for relevant information about nanotechnology and nanoparticles contained in products currently being sold in Korea.MethodsOne thousand and seven adult consumers (aged 20–50 years) were randomly selected from all over South Korea between November 1 and 9, 2010. We surveyed the origin and degree of their concern and their need for information and education regarding nanomaterials.ResultsAnalysis of the survey results showed no significant differences in responses by sex, age, and level of education, but significant differences were found in responses based on average monthly household income. Our research showed that consumers have vague expectations for and positive image of nanotechnology and nanoproducts but do not clearly understand what they are. In addition, we found that preparing and disseminating information to consumers is required in order to provide correct information about nanotechnology to the public.ConclusionA communication system should be established among the multiple stakeholders involved with nanomaterials to address consumer expectations and concerns. Further, a safety evaluation system must be set up, the results of which should be processed by a reliable expert group so they can be disseminated to the public.
