We all know that we can reduce our risk of exposure to viruses and bacteria by washing our hands before we eat. New research in ES&T (DOI: 10.1021/es7029625)
suggests that good hygiene may also help protect people—especially
children—from taking up persistent organic pollutants (POPs) from
everyday objects like TVs and cell phones.
A team led jointly by Heather Stapleton, an assistant professor at Duke University's Nicholas School of the Environment, and Tom Webster,
associate chairman of the Boston University School of Public Health's
environmental health department, measured the concentrations of PBDE flame retardants
on the hands of 33 U.S. volunteers, including 6 children. They used
sterile gauze pads in a hand-wipe procedure developed for assessing
exposure to contaminants like pesticides in occupational settings.
