Key value for chemical safety assessment

Additional information

Several sediment studies are available on a variety of sediment dwelling species, some of which were directly referenced in the REACH guidance, others which were not but were based on published methodologies and performed in order to collect a large set of chronic data using an array of organisms with different habitats and feeding strategies in order to prepare a Species Sensitivity Distribution for aluminium. Recommended species tested were as follows:

Chirmonus riparius, Hyalella azteca,

Other species:

The snail, Lymnaea stagnalis, the aquatic oligochaete, Aeolosoma sp.

The robust summaries for these species have been compiled together with the results from aquatic toxicity studies, in the section "long term toxicity to aquatic organisms"
