Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

No data are avialble for DTPA, but only one acute toxicity study with earthworms is available for EDTA-H4 (Edwards, 2009). The EC50 was determined at 156 mg/kg soil dry weight. This corresponds to 217 mg/kg soil dw DTPA-FeHNa.

Key value for chemical safety assessment

Short-term EC50 or LC50 for soil macroorganisms:
217 mg/kg soil dw

Additional information

The hazard assessment of DTPA-FeHNa reveals neither a need to classify the substance as dangerous to the environment, nor is it a PBT or vPvB substance. The substance is expected to have a low potential for adsorption based on its ionic structure under environmental relevant pH conditions and its low log Kow , the low log Kow also indicates that the substance will not be bioaccumulative. There are no further indications that the substance may be hazardous to the environment.
