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. (read more)
