Release of iron and chromium from alloys, pure metals and chromium oxide in ALF. Amounts of iron and chromium released per amount of iron and chromium in particles loaded (μg/μg) (top), and corresponding release rates (μg/cm2/h) (bottom) from coarse and fine sized particles (based on BET area) of alloys (FeCr, FeSiCr, 316L), alloy dust (FeCr dust, FeSiCr dust), pure metals (Fe, Cr), and chromium(III)oxide (Cr2O3) immersed in artificial lysosomal fluid (pH 4.5) for 168 h (1 week). Error bars represent the standard deviation of triplicate samples. Inset graphs are of higher magnification.
