Carbon Black – Exposure

Carbon Black (CB) can principally be taken up through the air we breathe, by swallowing or via the skin. At present, there are no studies that investigate explicitly the release of nanoscale carbon black from products during use. Provided that the operation of a carbon black-producing factory remains undisturbed, there will be no release of nanoscale particles.

It is difficult to distinguish between an environmental exposure with synthetically produced Carbon Black (CB) and soot from combustion processes (e.g. traffic exhaust). The latter contains many harmful substances produced by combustion processes, which bind effectively to the carbon particles.

In cell culture systems, the addition of medium doses of Carbon Black (CB) induces the formation of reactive oxygen species (ROS) while high doses decrease the viability of the cells.

While small doses of Carbon Black (CB) do not cause any damage, very high doses can cause tumors of the lung.
