Description of key information
Additional information
Magnesium carbonate and magnesium and carbonate ions are ubiquitous in the environment and are found naturally in soil, water and sediment. Magnesium is an important constituent of most soils and the minerals found in soil are mostly compounds of magnesium with other substances. Moreover, magnesium is essential to life and magnesium carbonate is intentionally applied to soils as an important constituent of fertilisers to ensure an adequate supply of magnesium to plants.
Given magnesium's essentiality, the natural occurrence of magnesium and magnesium carbonate in the environment, and the extensive and continued use of magnesium carbonate as a constituent of fertiliser, the performance of toxicity tests on terrestrial invertebrates is scientifically unjustified.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
