Recent research has tied environmental toxins to the development of obesity. Known as persistent organic pollutants (POPs), the contaminants were found to have a direct correlation with fat mass. The results showed that blood plasma concentrations of octachlorodibenzo-p-dioxin (OCDD), PCBs, and the pesticides HCB, TNK, and DDE were all found to lead to higher fat mass. The group with the highest blood content of PCB 105 were found to have a mean fat mass that was 10 pounds higher than those in the lowest 20 percent.
GreenMedInfo reports on the study:
BACKGROUND: Environmental contaminants have recently been implicated in the pathogenesis of obesity.
OBJECTIVE: To explore relations between persistent organic pollutants (POPs) and fat mass independently of body stature, using a cross-sectional design.
METHODS: In the Prospective Study of the Vasculature in Uppsala Seniors (PIVUS), fat mass was determined in 70-year-old subjects (n=890) by dual-energy X-ray absorptiometry (DXA). The plasma levels of 21 POPs (including 16 PCB congeners, 3 OC pesticides, 1 BDE47, and 1 dioxin) were measured by high resolution chromatography coupled with high resolution mass spectrometry (HRGC/HRMS).
