- JUSTIFICATION FOR DATA WAIVING
A study is not applicable to the substance. Calcium carbonate as component of the substance 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 short term toxicity tests on terrestrial arthropods is scientifically unjustified.
