Mean 8-h TWA concentrations of respirable dust and chrysotile fibers are numerically highest for specialists...
Raleigh, NC (PRWEB) November 30, 2014
Researchers say drywall specialists who have worked in older buildings tend to breathe in more dust than is currently considered safe and the exposure could raise their risk for deadly malignant pleural mesothelioma. Surviving Mesothelioma has just posted the story on their website. Click here to read it now.
Scientists with ENVIRON International Corporation in Chicago collected information on groups of workers exposed to drywall dust. Until the mid-1970s, most drywall was put up using joint compound that contained asbestos, the leading cause of mesothelioma.
“On a task basis, we found mean 8-h TWA concentrations of respirable dust and chrysotile fibers are numerically highest for specialists, followed by generalists, DIYers, and bystander tradespersons,” writes lead author Fred Boelter.
According to the report in Risk Analysis, concentrations of mesothelioma-causing dust are estimated to be higher than the current safety standards.
“Because we still do not know how much asbestos it takes to trigger mesothelioma, a study like this one is a reminder, especially to DIYers, that we all need to be diligent about limiting exposure to drywall dust,” says Surviving Mesothelioma’s Managing Editor, Alex Strauss.
