Size distribution of TiO2 particles in the maternal perfusion medium and the foetal exudate. Primary size distribution of TiO2 particles by number based on diameters measured on SEM-EDX images corresponding to samples of foetal exudate collected between 20 and 30 mn of E171 perfusion in 2 placentae, and compared to E171 suspension (solid line) in the perfusion medium (PM). P1 = 144 particles, P2 = 156 particles, and E171 in PM = 300 particles
