Dolomite Can Cause Irritation to Eyes, Skin, Respiratory System, and Gastrointestinal Tract & Cancer

Crystalline silica (RCS) may cause cancer. Dolomite is a naturally occuring mineral complex that contains varying quantities of quartz (crystalline silica. Lhoist North America disclosed that dolomite contact “can cause irritation to eyes, skin, respiratory system, and gastrointestinal tract,” adding that “long-term exposure may cause permanent damage.”

Is dolomite dangerous to humans?

CBI concluded that while its data “cast doubt on the notion that dolomite is a harmless chemical, they provide evidence in favor of the proposition that exposure to high atmospheric concentrations of these compound is likely to be associated with respiratory symptoms.”

In its website, Lhoist North America disclosed that dolomite contact “can cause irritation to eyes, skin, respiratory system, and gastrointentestinal tract,” adding that “long-term exposure may cause permanent damage.”


“However, this product may contain trace amounts of crystalline silica in the form of quartz or crysbobalite, which has been classified by IARC as a Group I carcinogent to humans when inhaled,” reported the firm, a subsidiary of Belgium-based Lhoist Group the which is the global distributor of lime, dolime, and other minerals.

Meanwhile, the Lehigh Hanson Inc. released a safety data sheet for dolomite, classifying the material used for manufacture of brick, cement, and other construction materials, to Category 1A in terms of carcinogenicity.

“Respirable crystalline silica (RCS) may cause cancer. Dolomite is a naturally occuring mineral complex that contains varying quantities of quartz (crystalline silica),” the firm added.

Lehigh Hanson is a distributor of various construction materials, concrete products, and other industrial products.

Calcium and Calcium Magnesium Carbonate Specimens Submitted as Urinary Tract Stones

Of 8, 129 specimens submitted as urinary stones from 6,095 patients, 67 from 15 patients were predominantly calcium carbonate or calcium magnesium carbonate (dolomite) by infrared analysis. Detailed study of 1 man and 4 women who submitted 3 or more such specimens showed that all were of aragonite calcium carbonate crystal form in 2 women and all calcite in the man. All 3 patients had a long history of nephrolithiasis preceding submission of calcium carbonate stones. There was frequent and often painful spontaneous passage of many small stones. Medullary sponge kidney was reported in 2 patients. Specimens submitted by the other 2 women included dolomite and quartz artifacts. Of the other 10 patients 4 had calcite and 1 had aragonite (possibly true stones). Five patients had artifacts with dolomite in 3 and mixed specimens in 2. True calcium carbonate kidney stones and calcium carbonate artifacts may be difficult to distinguish, and dolomite and quartz artifacts may require x-ray diffraction for clear-cut diagnosis.

Dolomite sand: Non-viable as beach material; exposure leads to cancer, lung failure


Ridon warned that the country’s major dolomite sand supplier makes no mention that dolomite can be used as top fill for beaches. 

“Dolomite sand has typically been used for as: auxiliary materials for iron and steel, plate glass for construction materials, automotive glass, fertilizer, soil conditioner. Nothing in this list mentions dolomite as viable for use as artificial sand for beaches. So why is DENR insisting that there is nothing irregular about using dolomite sand in Manila Bay?”

Ridon said this is probably due to the proven ill effects of dolomite sand exposure on human health.

” Several studies consistently state that dolomite exposure is a hazard to human health:

a. May cause irritation of cornea, burning, itching and redness to the eye. b. Repeated or prolonged exposure may dry out the skin and cause irritation. c. Irritation of the lungs, coughing or choking may occur. d. Overexposure may cause silicosis, cancer, bronchitis, or emphysema.”
