Description of key information

Studies on other terrestrial organisms are available and these either do not show effects, or do show effects but at levels which are significantly higher than the PEC values in the chemical safety report. Since the CSA shows that there is no risk for the soil compartment, there is no indication for this test to be conducted. This is in accordance with column 2 of REACH Annex VII. 
Calcium carbonate and calcium and carbonate ions are ubiquitous in the environment and are found naturally in soil, water and sediment. Calcium is an important constituent of most soils and the minerals found in soil are mostly compounds of calcium with other substances. Furthermore, calcium carbonate is used as an inorganic fertiliser to improve soil quality, both pH and structure and guarantees an adequate supply of calcium to plants. Given the extensive and continued use of calcium carbonate as a constituent of fertiliser and its natural occurrence in the environment, it is considered that calcium carbonate would not have a detrimental effect on soil macroorganisms. Therefore, the performance of long term toxicity tests on terrestrial arthropods is scientifically unjustified.
