Description of key information
Waiving of studies:
The substance has no high potential to adsorb to soil and is not very persistent. In addition, 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.
The PEC/PNEC for the terrestrial compartment was calculated on the basis of the equilibrium partitioning method, resulting in values far below the trigger value of 1 for all calculated scenarios. In addition, chlorine dissipates rapidly in contact with soil with a DT50 of < 1 minutes. Therefore, long-term effects are not expected and consequently, short- and long-term toxicity testing on invertebrates, is not necessary.
In accordance with column 2 of REACH Annex IX and X, short and long-term toxicity to invertebrates (required in sections 9.4.1 and 9.4.4) do not need to be conducted as the equilibrium partitioning method was applied to assess the hazard to soil organisms.
