Description of key information

 No studies are available: Calcium fluoride is a inorganic compound and therefore will not be biodegraded. 

Key value for chemical safety assessment

Additional information

The substance is a reaction mass of calcium fluoride, calcium sulfate and calcium carbonate.

The substance  is composed of inorganic compounds and therefore it will not be biodegraded. Once released into the environment, calcium fluoride will ionise to a limited extent to form calcium and fluoride ions which will combine with various minerals to form a variety of other fluoride compounds.Calcium sulfate and calcium carbonate are inorganic substances and do not undergo biodegradation. They all will be degraded in the environment by means other than biodegradation. The ions will dissociate in the environment;

calcium will be assimilated by species in the water and is necessary to maintain a good chemical balance in soils, water and plants, carbonate and sulfur ions will become part of the carbon cycle and sulfure cycle, respectively.

Therefore testing soil simulation testing on reaction mass of calcium fluoride, calcium sulfate and calcium carbonate is considered scientifically unjustified.
