SECTION V: HEALTH HAZARDS
SUMMARY:
Natural diatomaceous earth (Kieselguhr) contains small quantities (typically <1%) of crystalline silica which is a
known cause of silicosis, a progressive, sometimes fatal lung disease. In a 1997 monograph (Volume 68, “Silica, Some Silicates,
Coal Dust and Para-Aramid Fibrils”), the International Agency of Research on Cancer (IARC) has classified “inhaled crystalline silica
from occupational sources” in Group 1 as a substance “carcinogenic to humans.” In making the overall evaluation, the IARC
Working Group noted that “There is inadequate evidence in experimental animals for the carcinogenicity of uncalcined
diatomaceous earth”. It further noted that “There is inadequate evidence in humans for the carcinogenicity of amorphous silica” and
therefore it was rated as “not classifiable as to its carcinogenicity to humans (Group 3)”. Natural diatomaceous earth is
predominantly amorphous silica.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE
Pre-existing diseases of the upper respiratory tract and lung such as bronchitis, emphysema, and asthma
