Particle Size

Particulate pollution in the past decade has been measured as PM10, that is particulate matter 10 microns in diameter or less, which is talcum powder size Recently the focus has shifted to smaller diameter particles, PM25, which denotes all particles 25 microns and smaller (bacteria sized)...

Talc for Pleurodesis

The talc we used (Steritalc; Novatech; Plan-de-Grasse, France) has median particle size of 336 μm and a mean particle size of 313 μm, which is more explicit than to talk about an amount of 95% of particles with a size >5 μm, and varies markedly by more than a factor of three in the physical characteristics of several talc preparations ....

Talc (Mg3H2(SiO3)4)

Talc administered into the pleural space of rats is distributed systemically throughout the body Talc elimination of radioactivity was determined in the urine and faeces and therefore Talc (Mg3H2(SiO3)4) has no bioaccumulation potential Exposure to talc does not lead to any relevant dermal absorption...
