Description of key information

Based on the solubility of strontium neodecanoate in water (45.07 g/L), a complete dissociation of strontium neodecanoate may be assumed. Upon dissolution, strontium and neodecanoate ions therefore determine the ecotoxicological potential (or lack thereof).Based on the calculated Kow value, neodecanoic acid is expected to have a Daphnia Chronic Value of 1.7 mg/L as determined by theECOSAR module of EPISuite_v4.00. Reliable data on chronic inverebrate toxicity of Sr, determined by effects on D. magna reproduction resulted in a 21 -d NOEC of 21 mg Sr/L (Biesinger and Christensen, 1972). In addition, further non-reliable chronic toxicity data for other freshwater crustacean species indicated long-term LC50 values well above 1 mg/L. Therefore, Sr has a low potential for chronic toxicity to aquatic freshwater invertebrates. With both strontium and neodecanoate species not being thought to pose any threat to aquatic invertebrates, strontium neodecanoate appears to have a low potential for chronic toxicity to aquatic invertebrates.
