Description of key information
Aluminium
The available reliable EC50 values from 11 algal growth inhibition studies, all performed with Pseudokirchneriella subcapitata, vary from 0.2 to > 4.9 mg Al/L (total). Most of the variation in results can be explained by differences in parameters of the test media, i.e. mostly differences in pH and DOC and to a lesser extent hardness.Under standard test (pH, DOC and hardness) conditions, however, aluminium appears to have a low potential for toxicity to freshwater algae.
LanthanumIn a growth inhibition test according to OECD TG 201, the toxicity of a soluble lanthanum salt (LaCl3) to Desmodesmus subspicatus was examined. The 72-h ErC50 and ErC10 of 16 mg/L La and 1.3 mg/L La (both based on measured) corresponding to 24.6 mg/L AlLaO3 and 2.0 mg/L AlLaO3, respectively, indicate that lanthanum has a low potential for toxicity to freshwater algae.
Key value for chemical safety assessment
