Description of key information
Acute toxicity to Eisenia fetida was tested in a study according to EPA/600/3-88/029 (1988) using Ammonium chloride as test substance (CAS: 12125 -02 -9). The 14d- LC50 value was 201 mg/kg soil (Yeardley et al. 1995, value related to Ammonium sulphate). Ma et al. (1990) studied long-term effects (20 yr) on nitrogenous fertilizers usage on lumbricid earthworms in soil. This study revealed that, Ammonium sulphate (5 applications per year of 60 -180 kg N/ha had effects on earthworm numbers and biomass. However, the effects were attributed to the lowering of pH observed in parallel with Ammonium sulphate application in the absence of liming.

Additional information
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.
