Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
This endpoint is not relevant for aluminium nitride because the substance is inorganic.
Key value for chemical safety assessment
Additional information
For an inorganic substance biotic degradation in the environment is an irrelevant process. Here, the chemical assessment is based on the elemental concentration (i.e. pooling all aluminium speciations). Biotic processes may alter the speciation of an element, but it will not eliminate the element from the environment by degradation or transformation processes.
Ammonia can serve as a nutrient in soil, which can be taken up by plants and microorganisms and converted to organic nitrogen compounds. Ammonia in soil can be rapidly transformed to nitrate by the microbial population through nitrification (Atlas and Bartha 1998; Payne 1981). The nitrate formed will either leach through the soil or be taken up by plants or other microorganisms. Very high localised concentrations of ammonia, such as those that might occur after a spill, or an excessive application, of ammonia-containing fertilisers, can be toxic to plants, other organisms, or microbiota, which if inhibited or killed, will result in a decrease of the rates of any related nitrogen transformation processes. Under these conditions, other fate processes dictated by the physical and chemical properties of ammonia will dominate until the ammonia concentration returns to a background level. These physical and chemical processes include binding to soil particles (including organic carbon) or undergoing volatilization to the atmosphere. The nitrate formed will participate in one of the largest natural nutrient cycle, the nitrogen cycle.

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.
