Toxicity to birds:

In an avian repeated dose toxicity study with Japanese quails the NOEL was determined to be 200 mg chlorine/L. The LOEL was 400 mg chlorine/L based on smaller but functional testes.

Waiving of other terrestrial toxicity studies:

In accordance with column 2 of REACH Annex IX and X, terrestrial toxicity studies (required in sections 9.4.X and 9.6.1) do not need to be conducted as the equilibrium partitioning method was applied to assess the hazard. The substance has no high potential to adsorb to soil and is not persistent. In addition, chlorine dissipates rapidly in contact with soil with a DT50 of < 1 minutes. Therefore, toxicological effects are not expected and consequently terrestrial toxicity testing is not necessary. Furthermore, the results of the chemical safety assessment do not indicate the need to investigate further the effects of the substance and/or relevant degradation products on terrestrial organisms.
