Duke University researchers handed out silicone wristbands to firefighters to measure their exposure to hazardous chemicals
“Firefighters have a 9 percent higher risk of being diagnosed with cancer and a 14 percent higher risk of dying from cancer than the general US population,”research by the US Centers for Disease Control and Prevention / National Institute for Occupational Health and Safety .
“It turns out that ordinary silicone wristbands, like the ones sold in stores, absorb the semi-volatile organic compounds you’re exposed to while you’re out in the world,”Jessica Levasseur, a PhD student at Duke’s Nicholas School of the Environment, who led the study. “Firefighters have high cancer rates compared to the general population, but we don’t know why,” Levasseur points out.
The researchers recruited 20 firefighters and requested them to wear the silicone wristbands on days when they worked and separate wristbands on days when they were off. The study also revealed that “exposures to flame retardants and PAHs were associated with firefighting,” as the researchers wrote in the highlights of the study.
This research demonstrates that exposure to these chemical compounds is higher in firefighters than in adults performing other jobs, even when the firefighters did not actively respond to a fire while on duty.
