A recent study by the National Institute of Environmental Health Sciences indicates that in human beings of all sizes, ages and sexes, C8 may impact the body's ability to metabolize cholesterol.
The manmade manufacturing substances known as PFOA and PFOS have been found all over the world. An analysis of data from the National Health and Nutrition Examination Survey from 2003 - 2004 shows a correlation between elevated levels of C8 and cholesterol. The results were similar to those observed in other epidemiological studies.
The latest study calls for more investigation into human health effects of not only PFOA and PFOS exposure, but also exposure to other, lesser-known perfluorochemicals.
