The forms of amorphous silica for which there are or have been health standards are * ditomaceous earth-calcined,
* diatomaceous earth-uncalcined,
* precipitated and gel,
* fumed, and
* fused.
fumed is the only one that has no NIOSH, MAK, OSHA, of AIHA standard and the TLV was withdrawn.

Is silica gel the same thing as fumed silica (e.g. Cabosil, Aerosil)?
