Figure 1From: Bioaccessibility, bioavailability and toxicity of commercially relevant iron- and chromium-based particles: in vitro studies with an inhalation perspectiveParticle morphology of FeCr, FeSiCr, 316L, Fe, Cr, and Cr 2 O 3 by means of BE-SEM. SEM images of different magnification showing the morphology of the different particle types, with a) FeCr coarse (representative for FeCr fine and FeCr dust as well), b) FeSiCr fine (representative for FeSiCr coarse and FeSiCr dust as well), c) 316L coarse (representative for 316L fine as well), d) Fe coarse (as Fe fine), e) Cr coarse (as Cr fine), and f) Cr2O3.Back to article page
