At present, it is not expected that coconut shell charcoal becomes
systemically available at significant amounts. The Particle Size
Distribution has been determined using a standard sieve analysis. The
particles were found to be large in size, with a mean particle diameter
(D(50)) equalling 5.25 mm and an effective size (D10) of 3.52 mm.
the Read-Across substance charcoal smaller particles could be found: In
the granulometry studies performed with three representative charcoal
samples only a minor fraction was inhalable (particle sizes ≤ 100 µm)
and more importantly only a negligible fraction was respirable (particle
sizes ≤ 2 µm). In addition, there is no evidence for a significant
translocation of even smaller carbonaceous particles (35 nm) to the
systemic circulation upon inhalation (Wiebert et al. 2006).
