Chemicals in Rugs, Cookware May Be Linked to Raised Cholesterol in Teens

Common chemicals found in everything from non-stick cookware to grease-resistant food packaging appear to be associated with increases in cholesterol levels in adolescents, a new study suggests. People are exposed to these chemicals known as perfluoroalkyl acids (PFAAs)in dust, drinking water, non-stain carpets, waterproof fabrics, microwave popcorn bags and a host of other household products. "This is the first study that takes an in-depth look at an association between these chemicals and health effects in children," said study author Stephanie J. Frisbee, research instructor in the Department of Community Medicine at West Virginia University School of Medicine in Morgantown.

The PFAA compounds in question include perfluorooctanoic acid (PFOA) and perfluorooctanesulfonate (PFOS). "We found a positive association between PFOA and PFOS and total [cholesterol] and LDL cholesterol," she said. As the blood levels of these chemical increased, so did cholesterol, Frisbee added. The American Chemical Council, an industry group, did not respond to repeated attempts by HealthDay to get comment on the findings. The report is published in the September issue of the Archives of Pediatrics & Adolescent Medicine. For the study, Frisbee's team looked at cholesterol levels in more than 12,000 children and adolescents who are part of the C8 Health Project.

This project resulted from the settlement of a class-action lawsuit against Dupont over the landfill dumping of chemicals that contaminated groundwater in six water districts in two states near the company's plant in Parkersburg, West Virginia, and exposed residents to levels of C8 (another name for PFOA) far higher than that of the general population. Among the participants, the average PFOA concentration was 69.2 nanograms per milliliter and average PFOS concentration was 22.7 nanograms per milliliter. Among 12- to 19-year-olds, the PFOA concentrations were higher than those seen in the general population, but PFOS concentrations were similar to those seen in samples from the general population, the researchers found.
