Asbestos: the size and shape of inhaled nanofibers could be exclusively (scienmag.com)

The pathogenic potential of inhaling the inert fibrous nanomaterials used in thermal insulation (such as asbestos or fibreglass) is actually connected not to their chemical composition, but instead to their geometrical characteristics and size.

The reason for this is the inability of the macrophages naturally present in pulmonary alveolar tissue to eliminate foreign bodies that are too large.

This discovery poses a challenge for the use of inert nanofibre felts in construction, which had heretofore been deemed to be less harmful than the asbestos it replaced, but that in reality could present the same health risks for those handling it.

Four days and your only rebuttal is an insult and missing the point yet again? I knew it was pointless to point out your folley.

Lots of flammable stuff is also chemically stable at “great heat” (the fuck kind of unit is this…?), what’s your point? It seems you’ve just missed the point here actually.
