Bentonite toxicology and epidemiology
Abstract
Bentonite, a clay with many industrial and consumer applications, is mined and processed in many countries around the world. Its many useful applications, as well as for its widespread professional and consumer impact\n\n\npotential [1]. Existing studies on toxicity and epidemiology suggest that the main route of exposure is inhalation of dust inhaled by professionally affected cohorts. Bentonite itself is probably no more toxic than any other unregulated particle and has not been classified as carcinogenic by any regulator or advisory body, but in some bentonites, a variable amount of breathable crystalline silica is recognized for humans may be carcinogenic. Therefore, careful management and adherence to the limits of professional exposure are advisable. This review summarizes the available literature on bentonite production, application, effects, toxicity, and epidemiology, and identifies gaps and limitations in the data [ 2].
