Additional information

The toxicities of the three dilithium salts of dicarboxylic acids (C6-C10) to the carp (Cyprinus carpio) were determined in GLP-compliant, static, freshwater tests (Tobor-Kaplon 2015) following OECD guideline 203. In all studies the chemical confirmation of the test substance was based on analysis of the appropriate fatty acid, lithium and the total organic carbon (TOC). All three tests were conducted as limit tests at 100 mg/L. The results of the chemical analysis confirmed that all three test substances were stable over the 96 h duration of the tests and therefore all results are based on nominal concentrations. No fish mortalities were observed in any of the tests. A 96 h LC50 ≥ 100 mg/L was determined for all three substances. The results from these studies confirm similar low toxicity for dilithium adipate, dilithium sebacate and dilithium azelate to fish.
