Studies and Reports

• Entine J, Scare to Death: How Chemophobia Threatens Public Health, American Council on Science and Health, January 18, 2011.
• Fel C et al., Prenatal exposure to PFOA and PFOS and risk of hospitalization for infectious diseases in early childhood, Environ Res. 2010 Nov;110(8):773-7.
  • Conclusions. "These findings suggest that prenatal exposure to PFOA or PFOS is not associated with increased risk of infectious diseases leading to hospitalization in early childhood."
• Eriksen K et al., Perfluorooctanoate and perfluorooctanesulfonate plasma levels and risk of cancer in the general Danish population, J Natl Cancer Inst. 2009 Apr 15;101(8):605-9.
  • Abstract. "Perfluorooctanoate and perfluorooctanesulfonate are used in many industrial products and have been widely detected in human blood. Both chemicals are associated with tumor development in animal studies, but data on carcinogenic potential in humans are sparse. We investigated the association between plasma levels of perfluorooctanoate and perfluorooctanesulfonate and cancer risk within a prospective Danish cohort of participants with no previous cancer diagnosis at enrollment. From enrollment, between December 1, 1993, and May 31, 1997, and through July 1, 2006, we identified 713 participants with prostate cancer, 332 with bladder cancer, 128 with pancreatic cancer, and 67 with liver cancer in the entire cohort and we selected a comparison subcohort of 772. Plasma concentrations of perfluorooctanoate and perfluorooctanesulfonate were measured in each participant by use of high-pressure liquid chromatography coupled to tandem mass spectrometry. We found no clear differences in incidence rate ratios for these cancers in relation to plasma concentrations of perfluorooctanoate or perfluorooctanesulfonate. A 30%-40% increase in risk estimates for prostate cancer was observed for the three upper quartiles of perfluorooctanesulfonate concentration compared with the lowest quartile (eg, for the lowest vs the fourth quartile, incidence rate ratio = 1.38, 95% confidence interval = 0.99 to 1.93). Plasma concentrations of perfluorooctanoate and perfluorooctanesulfonate in the general Danish population appear not to be associated with risk of prostate, bladder, pancreatic, or liver cancer."
• Fel C et al., Prenatal exposure to perfluorooctanoate (PFOA) and perfluorooctanesulfonate (PFOS) and maternally reported developmental milestones in infancy, Environ Health Perspect. 2008 Oct;116(10):1391-5. Epub 2008 Jun 4.
  • Conclusion. "We found no convincing associations between developmental milestones in early childhood and levels of PFOA or PFOS as measured in maternal plasma early in pregnancy."
