Evaluation of the Acute Toxicity of an Ammonium Sulfate Fertilizer in Two Species of Anuran Tadpoles: Bufo mauritanicus (Schlegel 1841) and Rana ridibunda (Boulanger 1913)

Article scientifique 2020 Anglais

Résumé

As part of the ecotoxicological tests on anuran tadpoles, the authors propose to study the sensitivity of different stages towards a nitrogenous compound frequently used in Morocco (Ammonium sulphate). For this purpose, the acute toxicity tests on tadpoles of two species (Bufo mauritanicus and Rana ridibunda) belonging to different stages of development were carried out. The lethal effects after 96 hours caused by the pollutant used as a reference (potassium dichromate) as well as ammonium sulfate increase with concentration and vary according to the stage of development. Significant differences were observed in the sensitivity of the tadpoles to pollutants according to the stage of development. The tadpoles belonging to the early stages of development (stage 24 according to After 96 hours, the lowest effective concentration (LOEC) is observed in the tadpoles belonging to the early stages of development (Stage 24 according to Therefore, ammonium sulfate may play a role in the local decline of amphibians.
