Description
Curator's Comment: description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/8342726 | https://www.ncbi.nlm.nih.gov/pubmed/3415787 | https://www.ncbi.nlm.nih.gov/pubmed/23115717

Calcium magnesium carbonate (dolomite), a mineral with the chemical formula CaMg(CO3)2, is made up of 60% calcium carbonate (equivalent to 24% calcium) and 40% magnesium carbonate (equivalent to 12% magnesium). It is recommended by lay periodicals as a desirable source of calcium and magnesium, but found to be also a source of potentially toxic heavy metals. Exposure to high atmospheric concentrations of this compound is likely to be associated with respiratory symptoms.

Curator's Comment: Deodat Gratet de Dolomieu, a French geologist, was the first to describe dolomite in 1791.

In Vitro Use Guide
Dolomite powder contained particles of different shapes and size both microparticles (MPs) and nanoparticles (NPs), suggesting potential occupational exposure of these particles. An attempt was therefore, made to investigate dolomite toxicity in a particle size-dependent manner in human lung epithelial cells A(549). cytotoxicity profiles were estimated by exposing cells at concentration doses 100–1000 ug/ml by two different methods. LC50 values of MPs were 655 ug/ml and 675 ug/ml whereas for NPs were 278 ug/ml and 300 ug/ml in MTT and Trypan blue assays, respectively.
