Plasma concentrations varied significantly between experiments, especially when compared to a prior study with 4-week old animals. In the current study, male rat PFOA plasma concentrations are relatively constant in male rats across age groups, varying only with dose level. Female rat plasma concentrations. decreased with increasing age, but was only statistically significantly at the 30 mg/kg dose level, PFOA concentrations in urine, while not normalized for total elimination. indicated more rapid urinary excretion in female rats at all ages. The plasma concentrations from the supplemental group, however, ae significantly different from the main study levels or both male and female ats. The plasma concentration variability in 4-week old rats suggests an unknown physiological variabiliy in animals younger than 5 weeks. As a result, the relationship between age and PFOA plasma concentration is undefined in 3-4 week-old rats following oral dosing with 10 or 30 mglkg PFOA. A Plasma PFOA plasma concentrations in malerats were not significantly different by sample time (at 2 and 24 hours) or by animal age (3.4 or 5 weeks)a either 10 or 30 mg/kg. except at 2 hours and S weeksofage. The PFOA plasma concentrations in female rats were significantly lower at 2co4ncHeonutrrsatpioosntsdowseirnega(lcsoomlpoawreerdftoo5r2 hweoeuks-)0latdarlaltsagtehsanan3dadnods4eswteeeskte-d0.ldFreamtaslaet bpoltahsmsaample times and doses (p< 0.01). The PFOA plasma concentrations following a 30 mg/kg dose were approximately 1.5 to 4 times higher than those observed following a 10 mg/kg dose. Ina prior study, male and female rat PFOA plasma concentrations were measured at 24 hours post-dosing following a single 10 mg/kg oral gavage dose. PFOAplasma concentrations are consistent with the current study for bothsexesat 5 weeksofage but not at 4 weeksofage (3- week old animals were not previously measured). The standard deviatariesomnalsl in both studies, indicating that both are studies is whether the rats were internally consistent. fasted before dosing.
