“…Exposure to perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) has been associated with higher serum lipid concentrations in children and adolescents (Frisbee et al, 2010;Geiger et al, 2014), adults (Eriksen et al, 2013;Nelson et al, 2010;Steenland et al, 2009), and pregnant women (Starling et al, 2014). Current evidence on the influence of PFAAs on serum lipid concentrations in humans originates from cross-sectional epidemiologic studies, thus causal inference is limited.…”
