| renal clearance of perfluorooctane sulfonate and perfluorooctanoate in humans and their species-specific excretion. | perfluorooctane sulfonate (pfos) and perfluorooctanoate (pfoa) are detected in the environment, as well as more specifically in wildlife and humans. however, the toxicokinetic aspects of perfluorochemicals in humans are unclear. in this study, we measured concentrations of pfoa and pfos in subjects who had lived in kyoto city for more than 10 years. the serum concentrations of pfoa and pfos were higher in females who menstruated than those who did not menstruation (p<0.01), but in males this did ... | 2005 | 16194675 |
