Carbon black (CB) is the primary nanoparticulate component of air pollution from fossil fuel combustion. This work examines the cellular impact of ultrafine carbon (carbon black, CB) nanoparticles, that range in size down to 30 nm, upon murine macrophages. The size analysis of the carbon black nanoparticles was performed using atomic force microscopy (AFM) and transmission electron microscopy (TEM) techniques. RAW246.7 macrophage cells were exposed to CB doses ranging from 50 – 200 ug/ml in complete media. Analysis of cell survival over time revealed elevated rates of significant nuclear degradation and cell lifting after 48 hours of exposure, and in …
