Ecotoxicological information

Toxicity to soil macroorganisms except arthropods

Administrative data

toxicity to soil macroorganisms except arthropods: long-term
Type of information:
experimental study planned
Justification for type of information:
The PNECs for soil and sediment cannot be established by applying the
equilibrium partitioning method (EPM) since there is no hazard identified to
the aquatic environment. The low water solubility, high log Kow and high log Koc of the substance indicates that the substance has the potential for adsorption to sediment/soil and concern for soil/sediment organisms cannot be excluded. After consulting the ECHA help desk it was advised to perform the long-term terrestrial toxicity test to clarify the concern, while the results of this study can be used in a weight of evidence approach together with the absence of long-term effects in aquatic organism up to the solubility limit of the substance to conclude on the PNEC soil and sediment. This approach would allow to asses the risk of the substance to terrestrial organism, ensure its safe use and prepare the CSR.
