An article published in Science News last week revealed that elevated levels of four perfluorinated chemicals including C8 have been found in emergency workers who responded to the World Trade Center on 9/11.
New biomonitoring results have revealed that the responders have levels about twice as high as expected in the general public. The tragedy exposed thousands of people to smoke and dust containing the remains of the burning towers and including dioxins, fire retardant chemicals, and construction materials.
Researchers examined the blood of 457 workers - state personnel and national guardsmen - who worked at the site. The data will be used as a baseline for further study of the responders.
