Study Finds Public Relatively Unconcerned About Nanotechnology Risks

13.04.2011
A new study finds that the general public thinks getting a suntan poses a greater public health risk than nanotechnology or other nanoparticle applications. The study, from North Carolina State University, compared survey respondents’ perceived risk of nanoparticles with 23 other public-health risks.

The study is the first to compare the public’s perception of the risks associated with nanoparticles to other environmental and health safety risks. Researchers found that nanoparticles are perceived as being a relatively low risk.

“For example, 19 of the other public-health risks were perceived as more hazardous, including suntanning and drinking alcohol,” says Dr. Andrew Binder, an assistant professor of communication at NC State and co-author of a paper describing the study. “The only things viewed as less risky were cell-phone use, blood transfusions, commercial air travel and medical X-rays.”

In fact, 60 percent of respondents felt that nanoparticles posed either no health risk or only a slight health risk.

In the study, researchers asked a nationally representative panel of 307 people a battery of questions about how risky they believe nanoparticles are compared to 23 other public health risks – such as obesity, smoking, using cell phones and nuclear energy.

Policy implications of these findings could be substantial given the concerns expressed by proponents and opponents of nanotechnology that the public is wary of its environmental health and safety dangers. “The findings suggest just the opposite,” says Dr. David Berube, professor of communication at NC State and lead author of the study. “While it remains unclear whether nanoparticles are safe, they are not a major concern among the general public.”

The paper, “Comparing nanoparticle risk perceptions to other known EHS risks,” is forthcoming from the Journal of Nanoparticle Research. The paper was co-authored by Berube and Binder; Jordan Frith and Christopher Cummings, Ph.D. students at NC State; and Dr. Robert Oldendick of the University of South Carolina. The research was funded by the National Science Foundation.

NC State’s Department of Communication is part of the university’s College of Humanities and Social Sciences.

“Comparing nanoparticle risk perceptions to other known EHS risks”

Published: Forthcoming, Journal of Nanoparticle Research

Abstract: Over the last decade social scientific researchers have examined how the public perceives risks associated with nanotechnology. The body of literature that has emerged has been methodologically diverse. The findings have confirmed that some publics perceive nanotechnology as riskier than others, experts feel nanotechnology is less risky than the public does, and despite risks the public is optimistic about nanotechnology development. However, the extant literature on nanotechnology and risk suffers from sometimes widely divergent findings and has failed to provide a detailed picture of how the public actually feels about nanotechnology risks when compared to other risks. This study addresses the deficiencies in the literature by providing a comparative approach to gauging nanotechnology risks. The findings show that the public does not fear nanotechnology compared to other risks. Out of 24 risks presented to the participants, nanotechnology ranked 19th in terms of overall risk and 20th in terms of “high risk.”

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
