Carbon Black Particle Exhibits Size Dependent Toxicity in Human Monocytes
Figure 5
Percentage of cells capable of phagocytosing the indicator latex beads after the uptake of test particles (i.e., phagocytic monocytes). Cells were exposed to 1/2TC-50, TC-50, and 2TC-50 concentrations of nano carbon (295.7 μg/mL, 591.4 μg/mL, and 1182.8 μg/mL, resp.) and micro carbon (343.5 μg/mL, 687.1 μg/mL and 1374.2 μg/mL, resp.) for 4 h. The results are expressed as a percentage relative to controls and are presented as mean ± SEM of three independent replicate experiments. Significance is indicated by versus control.
