something I forgot to say yesterday.
Many chemicals may be present in man-made fibers,
which is not the case for asbestos fibers.
During the fabrication process many chemicals may be added=20
and they may account for up to 25 %
of the weight of these man-made fibers,
which may also be termed inorganic non-metallic
The chemicals added may be:
4-Anti-dust agents( mineral oils, polypropylene glycol)
5-Binders(urea-formaldehyde and epoxy resins, bitumen)
So, it is not an easy task to study the toxicity of these=20
