Fuller's earth (montmorillonite) pneumoconiosis.

Pneumoconiosis due to Fuller's earth.

The Origin of English Fuller's Earths

It is suggested that the source materials of the English Aptian fuller's earths were soils of the Anglo-Belgian Land and that montmorillonite is the characteristic clay mineral of marine deposits formed when old land surfaces of low relief are transgressed. When the origin of English fuller's earths was discussed in the 1930's, Grim (1933, 1935) and Newton (1934) engaged in a polemic. Grim main...

Inhibition of the absorption of paraquat from the gastrointestinal tract by adsorbents.

Clark, D. G. (1970). Brit. J. industr. Med., 27, 186-188. Inhibition of the absorption of paraquat from the gastrointestinal tract by adsorbents. The efficacy of the oral administration of adsorbents Kaolin, Decalso, Amberlite, Bentonite and Fuller's Earth in preventing the toxic actions ofingested paraquat (1,1'-dimethyl-4,4'-dipyridylium) has been assessed using rats and cats. Only Bentonite ...

Dendriform pulmonary ossification in patient with rare earth pneumoconiosis.

The case history is presented of a patient with pathologically proven dendriform pulmonary ossification and rare earth pneumoconiosis confirmed by analytical transmission electron microscopy. This is thought to be the first report of this association.

Distribution pattern of rare earth ions between water and montmorillonite and its relation to the sorbed species of the ions.

REE (rare earth element) distribution coefficients (Kd) between the aqueous phase and montmorillonite surface were obtained to investigate the relation between the REE distribution patterns and the species of REE sorbed on the solid-water interface. It was shown that the features in the REE patterns, such as the slope of the REE patterns, the tetrad effect, and the Y/Ho ratio, were closely rela...
